Samsung Electronics has started mass production of its 9th generation of V-NAND memory. The first dies based on their latest NAND tech come in a 1 Tb capacity using a triple-level cell (TLC) architecture, with data transfer rates as high as 3.2 GT/s. The new 3D TLC NAND memory will initially be used to build high-capacity and high-performance SSDs, which will help to solidify Samsung's position in the storage market.

Diving right in, Samsung is conspicuously avoiding to list the number of layers in their latest generation NAND, which is the principle driving factor in increasing capacity generation-on-generation. The company's current 8th gen V-NAND is 236 layers – similar to its major competitors – and word on the street is that 9th gen V-NAND ups that to 290 layers, though this remains to be confirmed.

Regardless, Samsung says that its 9th generation V-NAND memory boasts an approximate 50% improvement in bit density over its 8th generation predecessor. Driving this gains, the company cites the miniaturization of the cell size, as well as the integration of enhanced memory cell technologies that reduce interference and extend the lifespan of the cells. With their latest NAND technology, Samsung has also been able to eliminate dummy channel holes, thus reducing the planar area of the memory cells.

Interestingly, today's announcement also marks the first time that Samsung has publicly confirmed their use of string stacking in their NAND, referring to it as their "double-stack structure." The company is widely believed to have been using sting stacking back in their 8th generation NAND as well, however this was never confirmed by the company. Regardless, the use of string stacking is only going to increase from here, as vendors look to keep adding layers to their NAND dies, while manufacturing variability and channel hole tolerances make it difficult to produce more than 150-200 layers in a single stack.

Speaking of channel holes, another key technological enhancement in the 9th gen V-NAND is Samsung's advanced 'channel hole etching' technology. This process improves manufacturing productivity by enabling the simultaneous creation of electron pathways within a double-stack structure. This method is crucial as it enables efficient drilling through more layers, which is increasingly important as cell layers are added.

The latest V-NAND also features the introduction of a faster NAND flash interface, Toggle DDR 5.1, which boosts peak data transfer rates by 33% to 3.2 GT/s, or almost 400MB/sec for a single die. Additionally, 9th gen V-NAND's power consumption has been reduced by 10%, according to Samsung. Though Samsung doesn't state under what conditions – presumably, this is at iso-frequency rather than max frequency.

Samsung's launch of 1Tb TLC V-NAND is set to be followed by the release of a quad-level cell (QLC) model later this year.

"We are excited to deliver the industry’s first 9th-gen V-NAND which will bring future applications leaps forward," said SungHoi Hur, Head of Flash Product & Technology of the Memory Business at Samsung Electronics. "In order to address the evolving needs for NAND flash solutions, Samsung has pushed the boundaries in cell architecture and operational scheme for our next-generation product. Through our latest V-NAND, Samsung will continue to set the trend for the high-performance, high-density solid-state drive (SSD) market that meets the needs for the coming AI generation."

Western Digital has introduced its new series of SSDs aimed at mainstream PCs, which combine high performance and low cost. The Western Digital PC SN5000S family of DRAM-less drives uses the company's 3D QLC NAND memory and an in-house-developed platform, so the SSDs promise to be relatively inexpensive. Meanwhile, their sequential read performance reaches 6,000 MB/s.

Western Digital's PC SN5000S drives are based on the company's latest in-house controller, which supports a PCIe 4.0 x4 host interface and BICS6 3D QLC NAND memory. The controller fully supports Western Digital's nCache 4.0 HybridSLC technology with endurance monitoring to ensure decent performance, RSA-3K and SHA-384 encryption, and TCG Opal 2.02 and Pyrite security capabilities.

On the capacity side, Western Digital's PC SN5000S drives will be available in 512 GB, 1 TB, and 2 TB configurations. As for performance, the 2TB PC SN5000S is rated for up to 6,000 MB/s sequential read speed, up to 5,600 MB/s sequential write speed, up to 750,000 random read IOPS, and up to 900,000 random write IOPS. The SSDs will be available in M.2-2230 and M.2-2280 form factors.

When it comes to endurance, Western Digital rates 2TB PC SN5000S at 600 terabytes to be written, 1TB version at 300TBW, and 512GB at 150TBW, which is significantly lower compared to entry-level SSDs with similar capacities (yet higher compared to WD Green-branded drives). 

While the performance of Western Digital's PC SN5000S hardly impresses our avid readers, who tend to look at the highest-end SSDs, 1TB and 2TB versions offer considerably higher performance than most entry-level drives on the market today. What disappoints is the relatively low endurance of Western Digital's new SSDs compared to entry-level drives from other makers.

Western Digital primarily markets its PC SN5000S solid-state drives for OEMs, where they succeed the company's SN740-series. For PC makers, the drives are fast enough, and perhaps more importantly, they support advanced encryption technologies as well as TCG Opal 2.02 and Pyrite security capabilities, which is crucial for desktops and laptops sold to various U.S. government agencies.

Patriot has formally introduced its first solid-state drives featuring a PCIe 5.0 x4 interface aimed at demanding users. The Viper PV553 SSD uses the company's all-new active cooling system boasting an aluminum radiator, a blower fan, and a special heat shield that promises to ensure the best possible cooling for consistent performance under high workloads.

Set to be available in 1 TB, 2 TB, and 4 TB configurations, Patriot's Viper PV553 uses Micron's 232-layer 3D TLC NAND memory and we presume Phison's PS5026-E26 controller as Patriot is a loyal partner of the Taiwan-based SSD controller developer.

As for performance, Patriot rates its 2 TB and 4 TB PV553 for sequential read/write speeds of up to 12,400 MB/s and 11,800 MB/s as well as up to 1.4 million random 4K read and write IOPS. Meanwhile, the 1 TB model is slightly slower and offers read/write speeds of up to 11,700 MB/s and 9,500 MB/s as well as up to 1.3/1.4 million read/write IOPS.

The drives come in an M.2-2280 form-factor and are compatible with desktops that have sufficient space inside as Patriot's Viper PV553 SSDs are equipped with quite an extraordinary cooling system to take away 11W of thermal power that they can dissipate. The cooler (which features a 16.5 mm z-height) employs a rather big aluminum radiator that covers both the controller and memory chips, a blower fan, thermal pads on both sides of the drive, and an aluminum casing — which the company calls heat shield — that directs air produced by the fan through the radiator's fins to maximize cooling performance.

The extensive cooling is supposed to ensure that Patriot's Viper PV553 drives sustains performance even under severe workloads. In fact, Patriot says that the cooler ensures that the drive maintains temperature at about 45ºC in normal room temperature conditions.

Meanwhile, PV553 SSDs are not Patriot's fastest drives. Recently the company demonstrated its Viper PV573 SSDs that use Micron's B58R 3D TLC NAND with a 2400 MT/s data transfer rate and offer a sequential read and write speed of up to 14,000 MB/s and 12,000 MB/s, respectively. That drive will perhaps get more benefits from the new cooling system, but it will be available at a later date.

As it is always the case with Patriot's premium SSDs, the Viper PV553 drives are backed by a five-year warranty and are guaranteed to sustain 700, 1400, and 3000 terabytes to be written.

While enthusiasts are now focused mostly on SSDs with a PCIe 5.0 interface, there are many people who will be just fine with drives featuring a PCIe 4.0 interface to upgrade their PlayStation 5 or PCs bought a few years ago. To address these customers, SSD makers need to offer something that offers the right balance between price and performance. This is exactly what Corsair does with its MP600 Elite devices.

Corsair this week has released a new line of SSDs aimed at the mainstream market, the MP600 Elite. The drives are based on Phison's low-power highly-integrated PS5027-E27T platform, which is geared towards building mainstream, DRAM-less drives. The controller supports both 3D TLC and 3D QLC NAND flash via a four channel, Toggle 5.0/ONFi 5.0 interface, with data transfer rates up to 3600 MT/s. Meanwhile host connectivity is provided via a PCIe 4.0 x4 interface.

With its MP600 Elite SSDs, Corsair is not trying to offer the fastest PCIe Gen4 drives on the market, but rather attempts to offer the maximum value for 3D TLC-powered 1 TB, 2 TB as well as 4 TB configurations. The drives will offer sequential read performance of up to 7,000 MB/s and write performance of up to 6,500 MB/s, as well as random read and write speeds of up to 1,000K and 1,200K IOPS respectively, which is not bad for a PCIe Gen4 SSDs.

To maximize compatibility of its MP600 Elite drives (and make it compatible with Sony's PlayStation 5 and PlayStation 5 Slim), Corsair offers them both with a tiny aluminum heatspreader and an even thinner graphene heatspreader.

The main idea behind the Corsair MP600 Elite is its affordability: it does not require DRAM or a sophisticated cooling system, which optimizes the manufacturer's costs. Meanwhile, Corsair offers 1 TB MP600 Elite SSD with a graphene heatspreader for $89.99 and 2 TB MP600 Elite SSD with a graphene heatspreader for $164.99 (whereas versions with an aluminum heatsink are $5 cheaper), which is not particularly cheap. For example, a faster Corsair MP600 Pro LPX 2 TB costs $169.99.

Every drive is comes with a five-year warranty and can endure up to 1,200 terabytes written (TBW).

Virtually all client SSDs with a PCIe 5.0 x4 interface released to date use Phison's PS5026-E26 controller. Apparently, TeamGroup decided to try something different and introduced a drive powered by a completely different platform, the Innogrit IG5666. The T-Force Ge Pro SSD not only uses an all-new platform, but it also boasts with fast 3D NAND to enable a sequential read speed of up to 14 GB/s, which almost saturates the PCIe 5.0 x4 bus.

TeamGroup's T-Force Ge Pro PCIe 5.0 SSDs will be among the first drives to use the Innogrit IG5666 controller, which packs multiple cores that can handle an LDPC ECC algorithm with a 4096-bit code length, features low power consumption, has eight NAND channels, is made on a 12 nm-class process technology, and has a PCIe 5.0 x4 host interface. The drives will be available in 1 TB, 2 TB, and 4 TB configurations as well as will rely on high-performance 3D TLC NAND memory with a 2400 MT/s interface speed to guarantee maximum performance.

Indeed, 2 TB and 4TB T-Force Ge Pro drives are rated for an up to 14,000 MB/s sequential read speed as well as an up to 11,800 MB/s sequential write speed, which is in line with the highest-end SSDs based on the Phison E26 controller. Meanwhile, TeamGroup does not disclose random performance offered by these SSDs.

What is noteworthy is that to T-Force Ge Pro drives are equipped with a simplistic graphene heatspreader, which is said to be enough to sustain such high-performance levels under loads. Usage of such a cooler makes it easy to fit a T-Force Ge Pro into almost any system, a major difference with many of Phison E26-based drives. Of course, only reviews will reveal whether such a cooling system is indeed enough to properly cool the SSDs, but the fact that TeamGroup decided to go with a thin cooler is notable.

TeamGroup is set to offer its T-Force Ge Pro SSDs with a five-year warranty. Amazon, Newegg, and Amazon Japan will start taking pre-orders on these drives on February 9, 2024. Prices are currently unknown.
