Patriot Memory today announced the launch of the P400 V4, a high-performance PCIe Gen 4 x4 M.2 SSD that delivers exceptional speeds of up to 6,200 MB/s read and 5,200 MB/s write. This versatile storage solution is optimized for both PC and PlayStation 5 platforms, offering gamers and content creators unprecedented performance and reliability.

The P400 V4 leverages cutting-edge PCIe Gen 4 x4 NVMe technology to provide lightning-fast data transfer speeds while maintaining efficient power consumption. On the PlayStation 5, the drive achieves impressive sequential read speeds of up to 6,000 MB/s, ensuring quick load times and smooth gameplay across all gaming platforms.

Although it was revealed back in March this year, SK hynix new Platinum P51 PCIe 5.0 has only just now launched in South Korea and the specs have been boosted since March. The official sequential read speed is now rated at 14.7 GB/s vs. 13.5 GB/s in March and likewise, the sequential write speed has increased to 13.4 GB/s from 11.5 GB/s. We're also looking at a random IOPS read speed of up to 2,300k and random write IOPS of up to 2,400k. This compares really favourably compared to Phison E26 based SSDs, especially the random IOPS are very impressive.

However, it's not all good news, as the endurance tops out at 1200 TBW on the 2 TB SKU, which is pretty much what every other modern SSD offers today and somewhat disappointing considering that we're looking at SK hynix 238 layer 3D TLC NAND here. The 2 TB SKU is also the largest size available for now and the Platinum P51 will also come in 1 TB and 500 GB flavours. Another not so great, is the 10 W power consumption, even though SK hynix claims it's industry leading, but we know that this isn't true, as the Silicon Motion SM2508 controller is more power efficient than that. The drive has already been quickly benchmarked by South Korean hardware site Quasar Zone and it delivers in terms of the claimed speeds from the manufacturer, at least according to the CrystalDiskMark numbers. No pricing has tipped up as yet, so we'll have to wait to see how competitive the drive will be in an already crowded market. However, it's worth keeping in mind that SK hynix tends to charge a premium for its SSDs over many of its competitors.

Update Dec 14th: The 2 TB SKU has a retail price of 473,000 Korean Won, which equals about US$330, making it prohibitively expensive at the moment, even compared to most other PCIe 5.0 SSDs on the market. The 1 TB SKU comes in at 279,000 Korean Won, or about US$195. The Korean prices include 10% VAT/sales tax.

ADATA has launched the Legend 860 M.2 NVMe Gen 4 SSD series, aimed at mid-range users seeking a fast and reliable storage solution for PCs, laptops, or PS5 devices. Utilizing the PCIe Gen 4 x4 interface, the Legend 860 delivers sequential read and write speeds of up to 6,000 MB/s and 5,000 MB/s, respectively—three times faster than standard PCIe Gen 3 SSDs and ten times faster than SATA SSDs.

The lineup consists of three models with capacities of 500 GB, 1 TB, and 2 TB, each equipped with a slim aluminium heatsink. The ADATA Legend 860 utilizes 3D NAND flash chips and incorporates an SLC cache algorithm, HMB (Host Memory Buffer) technology, and an LDPC (Low-Density Parity Check) error correction mechanism, providing up to 640 TB TBW (Terabytes Written). ADATA offers a 5-year limited warranty, though pricing has not yet been disclosed.

Kingston Digital, Inc., the flash memory affiliate of Kingston Technology Company, Inc., a world leader in memory products and technology solutions, today announced it is shipping the NV3 PCIe 4.0 NVMe SSD for users looking for high capacity 4x4 NVMe PCIe performance in a compact form factor.

The Kingston NV3 PCIe 4.0 NVMe SSD is a robust next-gen storage solution powered by a Gen 4x4 NVMe controller. The Kingston NV3 delivers read/write speeds of up to 6,000/5,000 MB/s, ensuring a faster system capable of handling a variety of workloads, from editing to gaming. The drive optimizes system performance and delivers value without compromise. Its compact single-sided M.2 2280 (22x80mm) design allows for storage expansion up to 4TB2,5 while saving space for other components. As a cost-effective storage solution, the NV3 is ideal for creators and gamers looking to enhance their PC performance.[Editor's note: Our in-depth review of the Kingston NV3 is now live]

Kingston's NV2 NVMe SSD has been a popular budget choice that has offered some of the best price/performance ratio in its segment of the market. Now, Kingston has quietly added its replacement, the NV3 to its website and that entails a wide range of upgrades over the NV2. The Kingston NV2 came in a range of different variations with multiple different controllers and NAND types and so far the company hasn't revealed which controller or what NAND the NV3 will feature. However, the company lists 3D NAND with a sequential read speeds of 6,000 MB/s for the 1 TB and up SKUs which is a huge improvement over the NV2 which topped out at 3,500 MB/s. Write speeds top out at 5,000 MB/s, but this is limited to the 2 and 4 TB SKUs, but it's nearly twice that of the 2 TB NV2 SKU. The 1 TB SKU is also seeing almost a doubling in terms of write speeds over the NV2. The 500 GB SKU is seeing more modest performance improvements, but it's still getting a decent performance uplift.

Initially, Kingston will launch 500 GB, 1 TB and 2 TB SKUs, with the 4 TB SKU following in Q4 this year. Endurance remains the same as for the NV2, with the NV3 starting out at 160 TBW for the 500 GB SKU, which then doubles for each increase in size and tops out at 1280 TBW for the 4 TB SKU. Kingston has as yet to officially announce the drive, but some online retailers claim to be able to ship the NV3 in four to five days time, suggesting that the launch is imminent. Pricing appears to start at US$50 for the 500 GB SKU, which increases to US$70 for the 1 TB SKU, with the 2 TB SKU jumping to US$139 from the same retailer. This places the NV3 slightly higher than the current retail price of the NV2, which is hardly a surprise, considering it delivers better performance. All SKUs come with a three year warranty.

Western Digital has released a new budget friendly SSD that got a serious jump in model number, since the company decided to call it the SN5000. Its predecessor is the SN580 launched just under a year ago and price wise, it's the better option of the two. The new SN5000 uses the same BiCS 5 TLC NAND as the SN580 on the 500 GB to the 2 TB SKU, but according to Anandtech, the 4 TB uses BiCS 6 QLC NAND. The SN5000 is still a PCIe 4.0 x4 NVMe drive, but the overall performance has been significantly improved. If we use the 1 TB SKU for comparison, then the sequential read speeds have gone up by 1 GB/s from 4150 MB/s to 5150 MB/s. The sequential write speed is up 750 MB/s from 4150 MB/s to 4900 MB/s.

As for random performance, the read IOPS are up from 600K IOPS to 730K IOPS and the write IOPS are up slightly from 750K to 770K. The 4 TB QLC SKU is said to deliver even better performance with the exception of the random read IOPS. The 1 TB SKU is said to have a write endurance of 600 TBW, but the 4 TB SKU only offers 1200 TBW. That's 0.33 drive writes per day (DWPD) for the 1 TB SKU vs. 0.16 DWPD for the 4 TB SKU, showing the weakness of the QLC NAND. A new feature for the SN5000 series compared to previous WD Blue NVMe drives is support for TGC Pyrite 2.01 encryption. The WD SN5000-series starts at US$70 for the 500 GB model, going up to US$80 for 1 TB, US$140 for 2 TB and topping out at US$280 for the 4 TB model. WD only seems to have the 500 GB model in stock, with all the others being available in 3-4 weeks time. All SKUs come with a five year warranty.

SK hynix press release about its upcoming PCB01 PCIe 5.0 SSD was a bit light on details and Anandtech got a closer look at the upcoming drive at GTC 2024. Not entirely unsurprising, the drive will be called the Platinum P51 rather than the PCB01, which is a continuation of the branding SK hynix is using for its current range of SSDs. As we already know, it'll feature a custom SK hynix controller and no further data was revealed to Anandtech, but the publication did manage to get some more details with regards to the NAND flash used.

The Platinum P51 is SK hynix first consumer SSD with its new-ish 238-layer 4D NAND flash based on the company's PUC (peri. under cell) technology, which places the peripheral circuits under the cell array. The official performance figures of the Platinum P51 appears to be somewhat lower than the press release from earlier today stated, with sequential read speeds of up to 13.5 GB/s and sequential write speeds of 11.5 GB/s. SK hynix will apparently release the drive in the typical SSD sizes of 500 GB, 1 TB and 2 TB. It'll be interesting how SK hynix in-house controller will compare to the second generation of Phison E26 based drives paired with Micron B58R NAND flash once it becomes available later this year.

VisionTek Products LLC, a leading provider of high-performance upgrades and accessories for PCs and Macs, today unveiled its new lineup of M.2 solid-state drives (SSDs) featuring exceptional speed, thermal management and durability. These next-generation form factor M.2 drives cater to demanding workloads and offer blazing fast read and write speeds up to 7,500 MB/s.

The DLX4 PCIe 4.0 SSDs feature a PCIe 4.0 interface for high-bandwidth, low-latency performance for the most demanding of workloads. The range includes 2230, 2242 and 2280 SSDs to support a variety of systems and devices. Capacities range from 500 GB to 4 TB, making the SSDs perfect for applications like 3D rendering, gaming and video editing.

Client SSDs constituted a major driver of demand bit growth in the NAND Flash market for the past two years as the effects of the COVID-19 pandemic were spurring procurement activities related to working and studying from home. TrendForce currently projects that the attach rate of client SSDs among notebook computers will reach 92% in 2022 and around 96% in 2023. However, the demand surge related to the pandemic is subsiding, and the recent headwinds in the global economy have caused a demand freeze in the wider consumer electronics market. Hence, among the major application segments of the NAND Flash market, client SSDs are going to experience the most significant demand slowdown. This, in turn, will constrain demand bit growth as well. TrendForce projects that for the period from 2022 to 2025, the YoY growth rate of NAND Flash demand bits will remain below 30%.

The average NAND Flash content of client SSDs has already surpassed 500 GB this year. Quotes for 512 GB SSDs have fallen sharply and come to a level that is roughly comparable to the quotes that were given for 256 GB SSDs half-a-year ago. In fact, quotes for 512 GB SSDs are also near the level for HDDs with the same capacity. On the other hand, upgrading to 1 TB or higher for notebook SSDs could be challenging for PC OEMs mainly because the licensing fee for the Windows OS has a positive correlation with device specifications. Therefore, an increase in SSD capacity will raise the cost of a whole notebook computer. With PC OEMs being less keen on adopting SSDs that are 1 TB or higher, growth in the average NAND Flash content of client SSDs will also be more limited in the future.

Corsair has quietly launched two new SSD SKUs, the MP600 PRO NH and the MP600 GS. Although the model names seem similar, the two models couldn't be more different. Both are PCIe 4.0 x4 drives and in both cases controllers from Phison are used, but beyond both using a black PCB, the common features end here. The MP600 PRO NH is based around the Phison E18 and delivers sequential read speeds of up to 7000 MB/s, with the write speeds peaking at 6500 MB/s, depending on the storage capacity and this is where things get really interesting. Corsair is offering the MP600 PRO NH in capacities of up to 8 TB, but the SKU with the overall best performance is the 4 TB SKU. Random write performance is said to be up to 1.2 million IOPS, with random read performance topping out around 1 million IOPS. For some reason Corsair is offering a 500 GB SKU as well, but it offers fairly poor performance compared to its larger siblings. All drives use 3 TLC NAND, so we're not looking at QLC drives here.

The MP600 GS on the other hand is based on the Phison E21T, which is a DRAM-less controller that targets the more affordable drive segment. Here we're looking at only two SKUs, 500 GB or 1 TB, with the 1 TB drive offering sequential read speeds of up to 4800 MB/s and sequential write speeds of up to 3900 MB/s. The random read speed hits 580k IOPS with the random write speeds reaching 800k IOPS. This drive is also using 3D TLC NAND. The MP600 GS costs US$57.99 for the 500 GB SKU and US$92.99 for the 1 TB SKU. The MP600 PRO NH starts at US$72.99 for the 500 GB SKU, followed by US$112.99 for 1 TB, US$212.99 for 2 TB, US$529.99 for 4 TB and finally a rather steep US$1,074.99 for the 8 TB SKU. Both models come with a five year warranty.

(Update May 6: Added PNY's official word on the endurance changes)

PNY has quietly reduced the endurance rating (TBW - TeraBytes Written) for its XLR8 CS3030 M.2 NVMe SSD by almost 80%. The "quietly" comes from the fact that the company only deemed it necessary to update the product specifications on their website, and didn't announce any such changes via press release or any other means. Hence, prospective buyers who might look to launch reviews of this NVMe SSD so as to make a decision regarding its purchase may be led astray by the (then) quoted TBW ratings, which are actually no longer relevant for samples of this SSD - at the very least for any model manufactured post-specifications change on their website.

There are no other changes to specifications - neither in capacity, nor in Read/Write speeds. However, endurance has taken an almost 80% dive in the worst case scenarios - those of the 2 TB and 500 GB capacities, which saw reductions from their respective 3,115 TBW and 800 TBW down to 660 TBW and 170 TBW - or 78.8%. The 1 TB capacity takes a 78.4% dive in endurance (1665 TBW down to 360 TBW) and the 250 GB model is the least affected one, whilst still losing out 55.3% of its rated endurance (380 TBW down to 170 TBW).

Western Digital today introduced another addition to their PCIe 4.0 lineup - which previously consisted only on the WD Black 850, their enthusiast-level offering. Now, the Black 850 gets some entry-level company with the Black 750 SE, which makes use of a 4-channel DRAMless controller to keep the drive fed at some still respectable 3600 MB/s, Sequential Write, and 2830 MB/s Sequential Read speeds (WD isn't quoting the random read/write speeds just yet).

The new WD_Black SN750 SE will start at $49.99 for the 250 GB model. Pricing on the 500 GB and 1 TB capacities hasn't been announced at time of writing, nor is there a mention of a 2 TB model being a part of the current lineup plans. The WD_Black SN750 SE is available for preorder from WD now, and will land on store shelves this summer.

Crucial, Micron's global consumer brand of memory and storage, today launched an expansion of its award-winning portable solid-state drive (SSD) portfolio to offer consumers more options for external storage performance, capacity and value at any price point. The new products include the high-capacity 4 TB portable SSD at a RRP of 489.95 USD, and a new 500 GB portable SSD for a wallet-friendly RRP of 69.95 USD. Consumers looking to store large gaming libraries or more movies for long road trips will find an ideal solution in the Crucial X6.

With read speeds up to 800 MB/s, the 4 TB drive performs up to 5.6 times faster than portable hard drives in the market and are drop-proof up to 6.5 feet. Similar to the existing products in the Crucial X6 portable SSD lineup, the 4 TB and 500 GB versions deliver compact portable SSDs in these capacities to consumers for the first time. The entire award-winning Crucial portable SSD product line is compatible with the latest USB-C-enabled devices, such as PCs, Macs, PlayStation 5, Android devices and more. When used with the Crucial USB-C to USB-A adapter, the portable drives also work with PS4, Xbox One, XBOX Series S|X and other USB-A devices.

Samsung today has officially taken the lid off their latest consumer-oriented SATA SSDs, the 870 EVO. The 870 EVO series from Samsung don't push the maximum storage density ceiling on traditional SATA consumer drives, topping out at a maximum 4 TB, but they do achieve that ceiling whilst making use of Samsung's 128-layer TLC (Triple-Layer-Cell) NAND, which offers increased endurance (and higher theoretical performance than) more widespread QLC-based SSDs (of which Samsung launched the 870 QVO back in July 2020).

Samsung quotes SATA sequential read and write speeds of 560 MB/s and 530 MB/s respectively, with a "variable SLC" cache (which means it decreases in maximum size as the available free drive space decreases). The drives are also quoted at 98K IOPS Random Read, and 88K IOPS Write, and feature the company's Intelligent TurboWrite to maintain the interface's SATA 6 Gbps saturation as long as possible before sustained performance degradation appears. Samsung claims the 870 EVO also delivers a nearly 38% improvement in random read speeds over the previous 860 model, and quotes a (TBW) rating of 2,400 TB (or a 5-year limited warranty, whichever comes first) for its 4 TB model. The 870 EVO is available in either 256 GB, 512 GB, 1 TB, 2 TB, or 4 TB capacities, with the drives' RAM buffer scaling almost accordingly (512 MB DDR3 for the 256/512 Gb models, 1 GB for the 1 TB, 2 GB for the 2 TB drive, and 4 GB for the 4 TB one. Pricing starts at $49,99 for the 256 GB model; 500 GB for $79.99, 1 TB for $139.99; 2 TB for $269.99; and 4 TB for $529.99.

SK hynix Inc., a global semiconductor supplier based in Korea, announced today the release of its newest PCIe SSD: the SK hynix Gold P31. The latest edition is the world's first 128-layer NAND flash-based consumer SSD and the company's first consumer-facing PCIe SSD launched in the United States under the SK hynix brand.

The Gold P31 is intended for all PC users with a particular focus on gamers, designers, and content creators. The drive supports the PCIe NVMe interface based on 4D NAND flash technology and is now available for purchase in 1 TB and 500 GB capacities on Amazon U.S. The Gold P31 offers best-in-class read speeds of up to 3,500 MB/s and write speeds of up to 3,200 MB/s. The drive is a reliable choice for gamers whose PCs must support long hours of play, as well as professional creators and designers for whom performance and stability is essential. The Gold P31's reliability has been tested and validated through 1,000 hours of high-temperature operating life tests (HTOL) with mean time between failures (MTBF) reaching 1.5 million hours. The SSD also comes with a five-year warranty.

ADATA Technology, a leading manufacturer of high-performance DRAM modules and NAND Flash products, today announces the launch of the ADATA Ultimate SU720 SATA 6 Gb/s solid state drive (SSD). An ideal offering for those looking to make the switch to SSDs, the SU720 offers great performance and reliability at an amazing value. Equipped with 3D NAND memory and intelligent SLC caching, the SU720 reaches read/write speeds of up to 520/450 MB per second.

Back at CES 2019 we shared a story on Kingston's then upcoming A2000 series NVMe drives. The company's development strategy for these was to undercut SATA SSDs in pricing while delivering non SATA-bound speeds. The company planned to leverage component cost falls for NVMe controllers, pairing that with the reduced materials cost of NVMe drives (smaller than their SATA counterparts) so as to be able to achieve below-SATA price points. The choice of Toshiba's BiCS4 3D TLC NAND also aimed to keep costs down, whilst delivering performance that's "at least three times as high as SATA-bound drives".

The company is offering a limited 5-year warranty on their A2000 series, which in itself is a sign of the company's confidence in these products - despite their entry-level classification and overall development strategy. The A2000 series will be available in 250 GB, 500 GB and 1 TB capacities, with speeds claimed of up to 2,200/2,000MB/s sequential read/writes; up to 250,000/220,000 IOPS in random 4K read/writes; and 600 TBW rating (all of these values are for the 1 TB solution, with TBW falling to 350 TBW for the 500 GB part and 150 TBW for the 250 GB drive. These drives make use of a PCIe 3.0 4x controller, which means savings weren't at the expense of 2x PCIe channels, as some solutions have done in the past in order to cut costs. Pricing is being quoted at $40 for the 250 GB part, $60 for the 500 GB one, and a mere $100 for the 1 TB part. The true democratization of NVMe SSDs has just caught some heavy favorable winds on its sails.

Seagate, who are making strides in both storage density and performance of traditional HDDs with their HAMR and Multi-actuator technologies aren't going to let themselves be left dry in the SSD race. To that effect, the company, via a blog post, has just announced the introduction and availability of their barracuda SSDs, available in capacities up to 2 TB (in 250 GB, 500 GB and 1 TB additional tiers).

Like most recent SATA III SSDs, the Barracuda SSDs max out the data channel with maximum sequential read and write speeds reaching 540 and 520 MB/s respectively. There's a five-year warranty on these SSDs, which is in line with industry standards, and Seagate is asking $74.99 for the 250 GB SSD; $119.99 for the 500 GB one; and $229.99 for the 1 TB capacity. The 2 TB model will be available at a later date.

Western Digital and SanDisk have updated their Blue and Ultra line of consumer SSDs with the latest 3D BiCS FLASH NAND technology. Capacities will range from 250 GB capacities through 500 GB and up to 1TB at launch, with a 2 TB SanDisk Ultra 3D SSD "coming soon." The hardware powering each drive is exactly the same, save for the difference in available storage: the controller used is a Marvell 88SS1074, protocol is SATA 6Gbps / AHCI, and even warranty stays the same through all WD and SanDisk models, at three-years (limited.)

The WD Blue line of SSDs will be available in both 2.5" and M.2 2280 single-sided models. Sequential read speed starts at 550 MB/s for both WD Blue 250 GB and SanDisk Ultra 3D, with sequential write speeds at a rated 525 MB/s and read/write IOPS being set at 95,000/81,000 respectively. All other (higher) capacities deliver slightly more performance: 560 MB/s sequential read speeds, 530 MB/s sequential writes, 95,000 random read IOPS, and 84,000 random write IOPS. Pricing is as follows: WD Blue 3D 250 GB ($89); Blue 3D 500 GB ($149.99), Blue 3D 1 TB ($279.99); SanDisk Ultra 3D 250 GB ($99.99), Ultra 3D 500 GB ($164.99), Ultra 3D 1TB ($279.99) and Ultra 3D 2TB ($549.99, currently unavailable.)

Seagate has officially updated their FireCuda line, the solid-state supported, high-capacity hybrid drives. The new, 5th Gen models sport a thinner form-factor (2.5"), rocking the company's multi-tier cache technology as well as 1 TB SMR (Shingled Magnetic Recording) plates. The SMR plate's difference compared to conventional, perpendicular recording HDD technology allows these hybrid drives to increase storage density by up to 25%, by allowing newly-written magnetic tracks to partly overlap previously-written ones, reducing the amount of platter real-estate occupied.

The caveat with this technology is that the overlapping-tracks architecture may slow down the writing process, since writing to one track overwrites adjacent tracks, and requires them to be rewritten as well. However, according to Seagate, the large, multi-tier cache technology and large NAND caches are enough to offset any performance loss incurred by the SMR technology employed on these drives, and then some.
