Father of SQL Says Yes to NoSQL

Par : EditorDavid
12 mai 2024 à 15:34
An anonymous reader shared this report from the Register: The co-author of SQL, the standardized query language for relational databases, has come out in support of the NoSQL database movement that seeks to escape the tabular confines of the RDBMS. Speaking to The Register as SQL marks its 50th birthday, Donald Chamberlin, who first proposed the language with IBM colleague Raymond Boyce in a 1974 paper [PDF], explains that NoSQL databases and their query languages could help perform the tasks relational systems were never designed for. "The world doesn't stay the same thing, especially in computer science," he says. "It's a very fast, evolving, industry. New requirements are coming along and technology has to change to meet them, I think that's what's happening. The NoSQL movement is motivated by new kinds of applications, particularly web applications, that need massive scalability and high performance. Relational databases were developed in an earlier generation when scalability and performance weren't quite as important. To get the scalability and performance that you need for modern apps, many systems are relaxing some of the constraints of the relational data model." [...] A long-time IBMer, Chamberlin is now semi-retired, but finds time to fulfill a role as a technical advisor for NoSQL company Couchbase. In the role, he has become an advocate for a new query language designed to overcome the "impedance mismatch" between data structures in the application language and a database, he says. UC San Diego professor Yannis Papakonstantinou has proposed SQL++ to solve this problem, with a view to addressing impedance mismatch between heavily object-based JavaScript, the core language for web development and the assumed relational approach embedded in SQL. Like C++, SQL++ is designed as a compatible extension of an earlier language, SQL, but is touted as better able to handle the JSON file format inherent in JavaScript. Couchbase and AWS have adopted the language, although the cloud giant calls it PartiQL. At the end of the interview, Chamblin adds that "I don't think SQL is going to go away. A large part of the world's business data is encoded in SQL, and data is very sticky. Once you've got your database, you're going to leave it there. Also, relational systems do a very good job of what they were designed to do... "[I]f you're a startup company that wants to sell shoes on the web or something, you're going to need a database, and one of those SQL implementations will do the job for free. I think relational databases and the SQL language will be with us for a long time."

The People Who Won't Give Up Floppy Disks

Par : EditorDavid
11 mai 2024 à 21:34
Slashdot reader quonset writes: The last floppy disk was manufactured in 2011. Despite no new supplies being available for over a decade, there are still people, and organizations, who rely on floppy disks. Each has their own story as to why they rely on what is essentially 1970s technology. From the BBC: Tom Persky, a US businessman, has been selling "new", as in, unopened, floppy disks for years and still finds the trade lucrative. He runs Floppydisk.com, which offers disks for about US$1 (£0.80) each, though some higher capacity versions cost up to US$10 (£8) per disk, he says. Persky has customers all over the world and you could split them roughly 50-50 into hobbyists and enthusiasts like Espen Kraft on one side, and industrial users on the other. This latter category encompasses people who use computers at work that require floppy disks to function. They are, essentially, locked in to a format that the rest of the world has largely forgotten. "I sell thousands of floppy disks to the airline industry, still," says Persky. He declines to elaborate. "Companies are not happy about when I talk about them." But it is well-known that some Boeing 747s, for example, use floppy disks to load critical software updates into their navigation and avionics computers. While these older aircraft might not be so common in Europe or the US these days, you might find one in the developing world, for instance, Persky hints. There are also pieces of factory equipment, government systems — or even animatronic figures — that still rely on floppy disks. And in San Francisco, the Muni Metro light railway, which launched in 1980, won't start up each morning unless the staff in charge pick up a floppy disk and slip it into the computer that controls the railway's Automatic Train Control System, or ATCS. "The computer has to be told what it's supposed to do every day," explains a spokesman for the San Francisco Municipal Transport Agency (SFMTA). "Without a hard drive, there is nowhere to install software on a permanent basis." This computer has to be restarted in such a way repeatedly, he adds — it can't simply be left on, for fear of its memory degrading. The article also includes this quote from a cybersecurity expert at Pen Test Partners. "If floppy was the only interface, the only way to get malware on to [the computer] would be via said floppy disk. That's quite a limiting factor for the attacker..."

Sabrent Launches Rocket Nano M.2-2242 SSD: Up to 5 GB/sec

9 mai 2024 à 12:00

Sabrent tends to get into news when it launches ultra-high-performance SSDs for enthusiast-grade desktops, but this week the company introduced a completely different type of product: a small form-factor M.2-2242 SSD aimed at Lenovo's Legion Go handheld and ultra-thin laptops that don't accomodate M.2-2280 drives. And even though it's not an enthusiast-grade drive, the Rocket Nano still boasts with quite decent performance and capacity.

The Sabrent Rocket Nano 2242 (SB-2142) drive is based on the Phison E27T platform, a PCIe 4.0 x4 controller that is that is designed for mainstream DRAM-less SSDs, and in the case of the Rocket Nano, is paired with 3D TLC memory. The SSD is available in a single 1TB configuration, and is rated for read speeds up to 5 GB/s. Interestingly, the Phison E27T controller itself is rated for read speeds up to 7 GB/s, so it appears that the petite Rocket Nano isn't making full use of the controller's performance.

Sabrent positions its Rocket Nano 2242 SSD as drives for upgrading Lenovo's Legion Go portable game console, select Lenovo ThinkPad laptops, and other M.2-2242-sized PCs that can't accomodate larger 2280 drives. Keeping in mind that most devices shipping with M.2-2242 SSDscome with pretty slow stock drives, Sabrent solution seems to be a viable product for such upgrades. All the while, Sabrent's Rocket Nano 2242 will also work in systems with a PCIe 3.0 x4 M.2 slots, so the market for these drives is pretty wide.

Sabrent's Rocket Nano 2242 SSD 1 TB (SB-2142-1TB) SSD has a recommended price of $99.99, which is more or less in line with other 1 TB drives in the same form-factor and offering comparable performance. The SSD is currently available at Amazon for $101.

Le violent orage qui a frappé Dubaï a-t-il été causé par la manipulation de nuages ?

28 avril 2024 à 13:32

orage dubai

Dubaï a été récemment frappé par un épisode météorologique d'une ampleur rare, avec des précipitations exceptionnelles -- au point de provoquer des inondations. Une hypothèse a suggéré que le violent orage qui a frappé l'émirat était dû à un ensemencement de nuages qui a mal tourné. C'est toutefois improbable.

The 'Ceph' Community Now Stores 1,000 Petabytes in Its Open Source Storage Solution

Par : EditorDavid
27 avril 2024 à 17:34
1,000 petabytes. A million terabytes. One quintillion bytes (or 1,000,000,000,000,000,000). That's the amount of storage reported by users of the Ceph storage solution (across more than 3,000 Ceph clusters). The Ceph Foundation is a "directed fund" of the Linux Foundation, providing a neutral home for Ceph, "the most popular open source storage solution for modern data storage challenges" (offering an architecture that's "highly scalable, resilient, and flexible"). It's a software-defined storage platform, providing object storage, block storage, and file storage built on a common distributed cluster foundation. And Friday they announced the release of Ceph Squid, "which comes with several performance and space efficiency features along with enhanced protocol support." Ceph has solidified its position as the cornerstone of open source data storage. The release of Ceph Squid represents a significant milestone toward providing scalable, reliable, and flexible storage solutions that meet the ever-evolving demands of digital data storage. Features of Ceph Squid include improvements to BlueStore [a storage back end specifically designed for managing data on disk for Ceph Object Storage Daemon workloads] to reduce latency and CPU requirements for snapshot intensive workloads. BlueStore now uses RocksDB compression by default for increased average performance and reduced space usage. [And the next-generation Crimson OSD also has improvements in stability and read performance, and "now supports scrub, partial recovery and osdmap trimming."] Ceph continues to drive the future of storage, and welcomes developers, partners, and technology enthusiasts to get involved. Ceph Squid also brings enhancements for the CRUSH algorithm [which computes storage locations] to support more flexible and cost effective erasure coding configurations.

Seagate Joins the HDD Price Hike Party, Blames AI for Spike in Demand

Par : msmash
26 avril 2024 à 00:41
Seagate has joined Western Digital in increasing the prices of hard drives, with rising demand due to the huge data requirements of AI taking the blame. AI is also behind a rapid growth in orders for Enterprise solid state drives. From a report: One of the big three makers of traditional rotating hard disk drives, Seagate informed customers that it is increasing prices effective immediately for new orders, but also for any changes to orders that are "over and above" previously committed volumes. This was disclosed in a letter from the company seen by analyst Trendforce, and comes just a couple of weeks after rival manufacturer Western Digital sent out a similar letter to customers informing them of price hikes. According to Trendforce, the cause of the issue is two-fold: rising demand for high-capacity HDD products driven by the current craze for all things AI, and reduced production by hard drive manufacturers that means they are unable to meet the demand, leading to soaring prices. The rising demand comes from AI training requiring huge volumes of data: OpenAI's GPT-3 model is said to have been trained using 45TB of data, which may have been surpassed for newer models. And while flash-based SSDs boast high-speed and low-latency, storing everything in flash would still be costly. Seagate launched a 30TB hard drive line last year. Hard drive production was cut by as much as 20 percent over the last two years or so because of falling orders during the pandemic, and now manufacturers are unprepared for a sudden uptick in demand.

Report: Seagate, Western Digital Hike HDD Prices Amid Surge In Demand

24 avril 2024 à 16:00

Seagate Technology has reportedly notified its customers abouts its plans to raise prices on new hard drive orders and for demands that exceed prior agreements, echoing a similar move by Western Digital, which increased its prices earlier this month. These changes come in response to a surge in demand for high-capacity HDDs and constraints in supply due to decreased production capabilities of both Seagate and Western Digital, reports TrendForce.

According to industry insights reported by TechNews, the sector anticipates that the scarcity of high-capacity HDD products will persist throughout the current quarter and possibly extend over the entire year. It is forecasted that HDD prices will rise by 5% to 10% in Q2 2024 alone and could increase further as a reault of the ongoing challenges faced by the storage industry.

The primary driver behind Seagate's decision is increased demand for high-capacity HDDs, which are used to train AI models. This demand spike, coupled with a reduction in production output from hard drive makers, has created a significant supply-demand imbalance. As a result, Seagate has decided to adjust their pricing strategy to manage the situation. Further exacerbating the issue are global inflationary pressures which continue to inflate costs across the board, which also contributed to the company's decision to increase prices, Seagate said in a message to clients published by TrendForce.

Seagate emphasized that its reduced production capacity has been a major challenge, hindering the company's ability to fulfill customer demands fully and promptly.

"As a result, we will be implementing price increases effective immediately on new orders and for demand that is over and above previously committed volumes," the alleged memo from Seagate reads. "Supply constraints are expected to continue and as such we anticipate that prices will continue to increase in the coming quarters."

Earlier this month Western Digital also informed its customers about price hikes for its HDD and SSD products. This notification was based on similar issues — higher than anticipated demand across the whole product range and additional supply chain challenges affecting the electronics sector. Western Digital's announcement made it clear that these disruptions are likely to continue, prompting further price adjustments.

Seagate: Mozaic 3+ HAMR Hard Drives Can Last Over Seven Years

23 avril 2024 à 23:30

As Seagate ramps up shipments of its new heat assisted magnetic recording (HAMR)-based Mozaic 3+ hard drive platform, the company is both in the enviable position of shipping the first major new hard drive technology in a decade, and the much less enviable position of proving the reliability of the first major new hard drive technology in a decade. Due to HAMR's use of temporal heating with its platters, as well as all-new read/write heads, HAMR introduces multiple new changes at once that have raise questions about how reliable the technology will be. Looking to address these matters (and further promote their HAMR drives), Seagate has published a fresh blog post outlining the company's R&D efforts, and why the company expects their HAMR drives to last several years – as long or longer than current PMR hard drives.

According to the company, the reliability of Mozaic 3+ drives on par with traditional drives relying on perpendicular magnetic recording (PMR), the company says. In fact, components of HAMR HDDs have demonstrated a 50% increase in reliability over the past two years. Seagate says that Mozaic 3+ drives boast impressive durability metrics: their read/write heads have demonstrated capacity to handle over 3.2 petabytes of data transfer over 6,000 hours of operation, which exceeds data transfers of typical nearline hard drives by 20 times. Accordingly, Seagate is rating these drives for a mean time between failure (MTBF) 2.5 million hours, which is in-line with PMR-based drives.

Based on their field stress tests, involving over 500,000 Mozaic 3+ drives, Seagate says that the heads of Mozaic 3+ drives will last over seven years, surpassing the typical lifespan of current PMR-based drives. Generally, customers anticipate that modern PMR drives will last between four and five years with average usage, so these drives would exceed current expectations.

Altogether, Seagate is continuing aim for a seamless transition from PMR to HAMR drives in customer systems. That means ensuring that these new drives can fit into existing data center infrastructures without requiring any changes to enterprise specifications, warranty conditions, or form factors.

Lexar SL500 Portable SSD Review: Silicon Motion SM2320 and YMTC NAND in a Potent Package

23 avril 2024 à 12:00

Lexar has a long history of serving the flash-based consumer storage market in the form of SSDs, memory cards, and USB flash drives. After having started out as a Micron brand, the company was acquired by Longsys which has diversified its product lineup with regular introduction of new products. Recently, the company announced a number of portable SSDs targeting different market segments. The Lexar SL500 Portable SSD is one of the moderately priced 20 Gbps PSSDs in that set.

The SL500 is able to achieve its price point thanks to the use of a native USB flash controller - the Silicon Motion SM2320. The unique aspect is the use of YMTC 3D TLC NAND (compared to the usual Micron or BiCS NAND that we have seen in previous SM2320-based PSSDs). Read on for a detailed look at the SL500, including an analysis of its internals and evaluation of its performance consistency, power consumption, and thermal profile.

SK hynix Tube T31 Stick SSD Review: Bridging Solution Springs A Surprise

15 avril 2024 à 12:00

SK hynix is one of the few vertically integrated manufacturers in the flash-based storage market. The company is well-established in the OEM market. A few years back, they also started exploring direct end-user products. Internal SSDs (starting with the Gold S31 and Gold P31) were the first out of the door. Late last year, the company introduced the Beetle X31 portable SSD, its first direct-attached storage product. In February, a complementary product was introduced - the Tube T31 Stick SSD.

The Beetle X31 is a portable SSD with a Type-C upstream port and a separate cable. The Tube T31 is a take on the traditional thumb drive with a male Type-A interface. The size of the Beetle X31 makes the use of a bridge solution obvious. Our investigation into the Tube T31 also revealed the use of the same internal SSD, albeit with a different bridge. Read on for a detailed look at the Tube T31, including an analysis of its internals and evaluation of its performance consistency, power consumption, and thermal profile.

Western Digital Previews 4 TB SD Card: World's Highest-Capacity

11 avril 2024 à 22:30

Western Digital this week is previewing the industry's first 4 TB SD card. The device is being showcased at the NAB trade show for broadcasters and content creators and will be released commercially in 2025.

Western Digital's SanDisk Extreme Pro SDUC 4 TB SD card complies with the Secure Digital Ultra Capacity standard (SDUC, which enables up to 128TB). The card uses the Ultra High Speed-I (UHS-I) interface and is rated for speed Class 10, therefore supporting a minimum speed of 10 MB/s and a maximum data transfer rate of 104 MB/s when working in UHS104 (SDR104) mode (there is a catch about performance, but more on that later). WD's SD card is also rated to meet Video Speed Class V30, supporting a minimal sequential write speed of 30 MB/s, which is believed to be good enough for 8K video recording, above and beyond the 4K video market that Western Digital is primarily aiming the forthcoming card at.

For now, Western Digital is not disclosing what NAND is in the SanDisk Extreme Pro SDUC 4 TB SD card. Given the high capacity and relatively distant 2025 release date, WD may be targetting this as one of their first products to use their forthcoming BiCS 9 NAND.

And while not listed in WD's official press release, we would be surprised if the forthcoming card didn't also support the off-spec DDR200/DDR208 mode, which allows for higher transfer rates than the UHS-I standard normally allows via double data rate signaling. Western Digital's current-generation SanDisk Extreme Pro SDXC 1 TB SD card already supports that mode, allowing it to reach read speeds as high as 170 MB/s, so it would be surprising to see the company drop it from newer products. That said, the catch with DDR208 remains the same as always: it's a proprietary mode that requires a compatible host to make use of.

Western Digital has not disclosed how much will its SanDisk Extreme Pro SDUC 4 TB SD card cost. A 1 TB SanDisk Extreme Pro card costs $140, so one can make guesses about the price of a 4 TB SD card that uses cutting-edge NAND.

San Francisco's Light Rail To Upgrade From Floppy Disks

Par : msmash
9 avril 2024 à 07:52
Those taking public transport in the tech hub of San Francisco may be reassured to know that their rides will soon no longer be dependent on floppy disks. From a report: San Francisco Municipal Transportation Agency's director of transportation Jeffrey Tumlin told ABC that the city's automatic light-rail control system is running on outdated tech and "relies on three five-inch floppy disks" to boot up. The reporter was holding a 3.5-inch disk in the broadcast, so may have just skipped the word "point." "It's a question of risk," Tumlin explained in a three-minute segment about the floppy replacement project. "The system is currently working just fine, but we know that with each increasing year the risk of data degradation on the floppy disks increases and that at some point there will be a catastrophic failure." The agency noted that its system was installed in 1998, when floppies were still in common use and, er, "computers didn't have hard drives."

Cinephiles Rallying To Physical Media

Par : msmash
5 avril 2024 à 17:21
An anonymous reader shares a report: Streaming was supposed to kill physical media, and has come very close. The DVD and Blu-ray market fell from $4.7bn in revenue in 2017 to barely $1.5bn in 2022. In September, Netflix ended its movie-by-mail service. Best Buy has removed physical media from its brick-and-mortar stores, and Target and Walmart may follow. Some new films may never be released physically at all. Yet a counterrevolution has been gathering. Some film fans never gave up physical media: they've spent years quietly buying thrift-store discs, discarded by the many US households that no longer have DVD or Blu-ray players, and waiting for their chance to rise again. Other fans, frustrated by streaming's limitations, have recently rediscovered physical media and trickled to join its rear-guard army. Physical media will never regain its heights, but it may live to fight a little longer -- supported by loyalists and by a cottage industry of independent and boutique film distributors that license classic and cult films and sell high-quality physical editions to eager, sometimes frantic, fans. Some of these labels offer streaming channels or video-on-demand as well, but still find business in Blu-rays. "We've grown rather than shrunk," Umbrella Entertainment, a distributor in Australia, told me. And when Universal released Oppenheimer on 4K Blu-ray this fall, the initial run sold out, with feverish Christopher Nolan fans pillaging the same megastores that are moving to drop physical media. 4K Blu-rays are currently the smallest slice of the film disc market, and require ultra-high-definition players and TVs, meaning that the Oppenheimer run was driven by a niche within a niche. But the episode seemed to indicate that a market exists -- especially when it has champions. Nolan himself had encouraged fans to rally to physical media: "If you buy a 4K UHD, you buy a Blu-ray, it's on your shelf, it's yours," he told IGN last year. "[Y]ou own it. That's never really the case with any form of digital distribution."

Western Digital Ships 24TB Red Pro Hard Drive For NASes [UPDATED]

28 mars 2024 à 16:00

Nowadays highest-capacity hard drives are typically aimed at cloud service providers (CSPs) and enterprises, but this does not mean that creative professionals or regular users do not need them. To cater to demands of more regular consumers, Western Digital has started shipments of its Red Pro 24 TB HDDs, which are aimed at high-end NAS use for creative professionals with significant storage requirements.

Western Digital's Red Pro 24 TB hard drives come approximately 20 months after their 22 TB model hit retail in 2022, offering an incremental improvement to WD's highest-capacity NAS and consumer hard drive offering. The platform uses conventional magnetic recording (CMR), feature a 7200 RPM rotating speed, are equipped with a 512 MB cache, and use OptiNAND technology to improve reliability as well as optimize performance and power consumption. The HDDs are rated for an up to 287 MB/s media to cache transfer rate, which makes them some of the fastest hard drives around (albeit, still a bit slower compared to CSP and enterprise-oriented HDDs).

Just like other high-end network-attached storage-aimed HDDs, the Red Pro 24 TB hard drives use helium-filled platforms that are very similar to those designed for enterprise drives. Consequently, the Red Pro 24 TB HDD are equipped with rotation vibration sensors to anticipate and proactively counteract disturbances caused by increased vibration and multi-axis shock sensors to detect subtle shock events and automatically offset them with dynamic fly height technology to ensure that heads to not scratch disks.

UPDATE 4/2/2024: Western Digital has notified us that WD Red Pro fully support ArmorCache capability, even though it is not listed in datasheets.

What these drives lack compared Apparently, just like WD Gold and Ultraster 22 TB and 24 TB drives for enterprises and cloud datacenters, WD Red Pro HDDs fully support the ArmorCache feature that provides protection against power loss when write-cache is enabled (WCE mode) and enhances performance when write-cache is disabled (WCD mode).

On the reliability side of matters, Western Digital's Red Pro 24 TB HDDs are designed for 24/7 operation in vibrating environments, such as enterprise-grade NAS with loads of bays, and are rated for up to 550 TB/year workloads as well as up to 600,000 load/unload cycles, which is in line with what Western Digital's WD Gold and Ultrastar hard drives offer.

As for power consumption, the WD Red Pro 24 TB consumes up to 6.4W during read and write operations, up to 3.9W in idle mode, and up to 1.2W in standby/sleep mode.

Western Digital's Red Pro 24 TB (WD240KFGX) HDDs are now shipping to resellers as well as NAS makers, and are slated to be available shortly. Expect these hard drives to be slightly cheaper than the WD Gold 24 TB model.

SK hynix Platinum P51 Gen5 SSD with 238L NAND Spotted at GTC

20 mars 2024 à 01:45

SK hynix is set to unveil their first Gen5 consumer NVMe SSD lineup shortly, based on the products at display in their GTC 2024 booth. The Platinum P51 M.2 2280 NVMe SSD will take over flagship duties from the Platinum P41 that has been serving the market for more than a year.

Similar to the Gold P31 and the Platinum P41, the Platinum P51 also uses an in-house SSD controller. The key updates are the move to PCIe Gen5 and the use of SK hynix's 238L TLC NAND. Other details are scarce, and we have reached out for additional information.

SK hynix Platinum P51 Gen5 NVMe SSD Specifications
Capacity 500 GB 1 TB 2 TB
Controller SK hynix In-House (Alistar)
NAND Flash SK hynix 238L 3D TLC NAND at ?? MT/s ('4D' with CMOS circuitry under the NAND as per SK hynix marketing)
Form-Factor, Interface M.2-2280, PCIe 5.0 x4, NVMe 2.0
Sequential Read 13500 MB/s
Sequential Write 11500 MB/s
Random Read IOPS TBD
Random Write IOPS TBD
SLC Caching Yes
TCG Opal Encryption TBD
Warranty TBD
Write Endurance TBD TBD TBD

Only the peak sequential access numbers were available at the GTC booth, indicating that the drive's firmware is still undergoing tweaks. It is also unclear how these numbers are going to vary based on capacity. Availability and pricing are also not public yet.

This is a significant launch for the Gen5 consumer SSD market, where the number of available options are quite limited. The Phison E26 controller and Micron's B58R NAND combination is already in its second generation (with the NAND operating at 2400 MT/s in the newest avatar), but other vertically integrated vendors such as Samsung, Western Digital / Kioxia, and SK hynix (till now) are focusing more on the Gen4 market which has much higher adoption.

We will update the piece with additional information once the specifications are officially available.

First DNA Data Storage Specification Released: First Step Towards Commercialization

The DNA Data Storage Alliance introduced its inaugural specifications for DNA-based data storage this week. This specification outlines a method for encoding essential information within a DNA data archive, crucial for developing and commercializing an interoperable storage ecosystem.

DNA data storage uses short strings of deoxyribonucleic acid (DNA) called oligonucleotides (oligos) mixed together without a specific physical ordering scheme. This storage media lacks a dedicated controller and an organizational means to understand the proximity of one media subcomponent to another. DNA storage differs significantly from traditional media like tape, HDD, and SSD, which have fixed structures and controllers that can read and write data from the structured media. DNA's lack of physical structure requires a unique approach to initiate data retrieval, which brings its peculiarities regarding standardization. 

To address this, the SNIA DNA Archive Rosetta Stone (DARS) working group, part of the DNA Data Storage Alliance, has developed two specifications, Sector Zero and Sector One, to facilitate the process of starting a DNA archive. 

Sector Zero serves as the starting point, providing minimal details necessary for the archive reader to identify the entity responsible for synthesizing the DNA (e.g., Dell, Microsoft, Twist Bioscience) and the CODEC used for encoding Sector One (e.g., Super Codec, Hyper Codec, Jimbob's Codec). Sector Zero consists of 70 bases: the first 35 bases identify the vendor, and the second 35 bases identify the codec. The information in Sector Zero enables access and decoding of data stored in Sector One. The amount of data stored in SZ is small and fits into a single oligonucleotide.

Sector One expands on this by including a description of the contents, a file table, and parameters required for transferring data to a sequencer. This specification ensures that the main body of the archive is accessible and readable, paving the way for data retrieval. Sector One contains exactly 150 bases and will span multiple oligonucleotides. 

"A key goal of the DNA Data Storage Alliance is to set and publish specifications and standards that allow an interoperable DNA data storage ecosystem to grow," said Dave Landsman, of the DNA Data Storage Alliance Board of Directors. "With the publishing of the Alliance's first specifications, we take an important step in achieving that goal. Sector Zero and Sector One are now publicly available, allowing companies working in the space to adopt and implement."

The DNA Data Storage Alliance is led by Catalog Technologies, Inc., Quantum Corporation, Twist Bioscience Corporation, and Western Digital (though we are unsure whether Western Digital's NAND or HDD division is responsible for developing the specification). Meanwhile, numerous industry giants, including Microsoft, support the DNA Data Storage Alliance.
