Kioxia today introduced the Exceria Plus G4, a mid-range M.2 NVMe Gen 5 SSD. Built in the M.2-2280 form-factor, the drive takes advantage of the PCI-Express 5.0 x4 host interface, and comes in capacities of 1 TB and 2 TB. Both models offer sequential read speeds of up to 10,000 MB/s, but while the 1 TB model offers up to 7,900 MB/s sequential writes, the 2 TB model does up to 8,200 MB/s. 4K random access performance for both models are listed at up to 1.3 million IOPS reads, with up to 1.4 million IOPS writes. The 1 TB model endures up to 600 TBW of writes, while the 2 TB model is double that, at 1,200 TBW. Under the hood, the Kioxia Exceria Plus G4 appears to combine a Phison E31T series DRAMless NVMe Gen 5 controller, with Kioxia 218-layer BiCS flash memory. The company is backing the drive with 5-year product warranty. It didn't reveal pricing information.

Apacer today introduced the PE4430-R, a compact M.2 NVMe SSD in the M.2-2230 form-factor, which makes it suitable for handheld gaming consoles, such as the Steam Deck. The drive uses a graphene based heatspreader that's 0.17 mm-thick. It comes in 1 TB and 2 TB capacities, and appears to be based on a combination of a Phison E27T DRAMless controller, and a single 3D TLC NAND flash chip. It takes advantage of the PCI-Express 4.0 x4 host interface, offering sequential transfer speeds of up to 5500 MB/s reads, with up to 5200 MB/s writes, with around 700,000 IOPS of 4K random reads, and around 880,000 IOPS 4K random writes. The Apacer PE4430-R comes with some impressive endurance figures, of 500 TBW for the 1 TB variant, and 1,000 TBW for the 2 TB. The company didn't reveal pricing information.

Samsung Electronics just filed trademark paperwork for two unreleased client SSD models, the SSD 990 EVO Plus, and the SSD 9100 PRO. Having exhausted the three-digit model number sequence with the 990 PRO, Samsung is going with the 9000 series for the next nine generations of its flagship M.2-2280 client SSDs, beginning with the 9100 PRO, which will likely be succeeded in the future by the 9200 PRO, 9300 PRO, and so on. Nothing yet is known about the 9100 PRO, but we predict it to be Samsung's answer to the latest crop of Gen 5 drives that offer over 14 GB/s of sequential read speeds, and over 12 GB/s of sequential writes.

The Samsung 990 EVO Plus could be a whole different drive from the current 990 EVO, designed to compete with the value end of Gen 5 SSDs that are based on the new Phison E31T DRAMless Gen 5 controller with around 11 GB/s of sequential transfer speeds on tap. This is something the current 990 EVO cannot achieve, as its controller has a wacky logic that either uses Gen 4 x4 or Gen 5 x2 (it lowers the lane count upon detecting Gen 5). Samsung will probably remove this limitation with the 990 EVO Plus, allowing Gen 5 x4, and getting its performance in the league of the E31T-powered drives.

At Computex 2024, we paid a visit to the Patriot booth and found a few new product announcements from the company. From record-shattering DDR5 memory speeds to next-generation Gen 5 SSDs, the company has prepared it all. Headlining the showcase is the Viper Xtreme 5 DDR5 memory series, achieving regular speeds of up to 8,200 MT/s and an astonishing 11,500 MT/s when overclocked. Patriot is also launching something for professional workstations with its overclockable ECC RDIMM modules, offering error correction, larger capacities, and the ability to exceed industry specifications through overclocking.

Sabrent introduced the Rocket 2242 M.2 Gen 4 NVMe SSD. The drive is built in the M.2-2242 form-factor (42 mm long), which should make it suitable for certain kinds of handheld game consoles, such as the Legion Go. The Rocket 2242 comes in just one capacity for now, 1 TB. The drive combines a Phison E27T series DRAMless controller with Kioxia 162-layer 3D TLC NAND flash, and takes advantage of the PCI-Express 4.0 x4 host interface to offer sequential transfer speeds of up to 5000 MB/s. The company put out no other performance or endurance related specs. Sabrent is pricing the Rocket 2242 1 TB at USD $99.99, it is available now, and backed by a 5-year warranty.

KLEVV today announced the CRAS C925 line of mid-range M.2 NVMe SSDs. Built in the M.2-2280 form-factor, these drives take advantage of the PCI-Express 4.0 x4 host interface, to provide sequential transfer speeds of up to 7400 MB/s reads, and up to 6500 MB/s sequential writes, depending on the model. There are three of these based on capacity—500 GB, 1 TB, and 2 TB. All three offer up to 7400 MB/s sequential reads, while the maximum write speeds are up to 6200 MB/s for the 500 GB model, up to 6300 MB/s for the 1 TB model, and up to 6500 MB/s for the 2 TB model. Both the 500 GB and 1 TB models offer up to 670,000 IOPS 4K random reads, and up to 980,000 IOPS random writes; while the 2 TB model does up to 700,000 IOPS random reads, with up to 1 million IOPS random writes.

The KLEVV CRAS C925 combines a MaxioTech MAP1602 DRAMless controller with an unspecified brand of 3D TLC NAND flash memory. The drive features a single-sided design, in that even the top 2 TB model has all its components on one side of the PCB. You can use the included aluminium heat-spreader that reduces temperatures by 12%, or the heatsink your motherboard includes. KLEVV rates the write endurance of these drives at 600 TBW for the 500 GB model, 1,200 TBW for the 1 TB model, and 2,400 TBW for the 2 TB model. The company is backing the drives with a 5-year warranty. The company didn't reveal pricing, but mentioned that the drives will be available from May 2024.

Sabrent today debuted the Rocket 4 line of DRAMless M.2 NVMe Gen 4 SSDs. Built in the M.2-2280 form-factor, these drives take advantage of the PCI-Express 4.0 x4 host interface, and provide sequential transfer speeds of up to 7.4 GB/s reads, with up to 6.4 GB/s writes. The drives also offer 4K random access performance of up to 1 million IOPS reads, and 0.95 million IOPS writes. For now, Sabrent is launching 1 TB and 2 TB capacity variants of the Rocket 4, but the company is preparing to launch a larger 4 TB variant soon.

The Sabrent Rocket 4 combines a Phison E27T series DRAMless controller with Kioxia 162-layer 3D TLC NAND flash memory (also known as the BiCS 6). There's just a copper foil heat spreader to keep things cool. The 12 nm E27T doesn't run anywhere near as hot as the E18, so you can make do with the heatsink your motherboard includes, or run it the way it is. The 1 TB variant is priced at $99.99, and the 2 TB variant at $199.99. The company didn't reveal pricing of the unreleased 4 TB variant.

GIGABYTE today introduced the Gen 4 4000E line of value M.2 NVMe SSDs that take advantage of the PCI-Express Gen 4 host interface, as it says on the tin. These drives form the company's new entry level M.2 NVMe SSD series. The drive comes in 250 GB, 500 GB, and 1 TB capacities, and are really targeted at the crowd that likes to pick up well-priced processor+motherboard+DRAM+SSD bundles in the DIY retail channel. The company didn't specify controller and NAND flash type, but we gather from the specs sheet that it uses a DRAMless controller.

The 1 TB variant (model: G440E1TB) offers sequential speeds of up to 4 GB/s reads, with up to 3.9 GB/s sequential writes. The 500 GB and 250 GB variants offer speeds that don't really need Gen 4 bandwidth. The 500 GB model (G440E500G) does up to 3.6 GB/s sequential reads, with up to 3 GB/s sequential writes. The 250 GB (G440E250G) model offers 3.5 GB/s reads, with up to 1.8 GB/s sequential writes. Endurance is rated at 320 TBW for the 1 TB model, 300 TBW for the 500 GB model, and 150 TBW for the 250 GB model. All three models are backed by 3-year warranties. The company didn't reveal pricing.

The current crop of PCIe Gen 5 based M.2 NVMe SSDs run scorching hot to deliver sequential transfer speeds of 10 GB/s, requiring some massive cooling solutions with tiny fans. All this might change, as Phison, a leading SSD controller manufacturer, unveiled three new controllers at the 2024 International CES. One of these that stands out, is the PS5031-E31T, which is built on the 7 nm node, and could power the first Gen 5 SSDs delivering 10 GB/s without elaborate cooling solutions. This is a big upgrade from the 12 nm node used by their first Gen 5 controllers. The PS5031-E31T is a DRAMless controller meant for mainstream Gen 5 SSDs. This controller has a 4-channel flash interface (16 CE), a PCI-Express 5.0 x4 host interface, supports capacities of up to 8 TB, and is claimed by Phison to offer sequential transfer rates of up to 10.8 GB/s, and up to 1500K IOPS random access; exceeding the fastest Gen 4 SSDs.

Phison also updated its high-end controller lineup with the new PS5026-E26 Max14um. This is a variant of the E26 that's designed for the upcoming Micron B58R NAND flash chip that offers 2400 MT/s per channel transfers. Over the 8-channel interface of the E26, this finally unlocks sequential transfer speeds exceeding 14 GB/s reads, and 12.7 GB/s sequential writes. This is merely a revision of the existing E26 with updated power-optimized firmware, the underlying silicon is identical. The E26 Max14um is the first controller to surpass 1000 MB/s in all three PCMark 10 storage tests. We have a sample of an SSD powered by the E26 Max14um in our labs, and will post our review soon.

With IMAGIN+ design services, Phison teams work hand-in-hand with customers to deliver AI-boosted SSD solutions that address demanding requirements.

Innodisk has the right idea about how to do PCIe Gen 5 NVMe SSDs—to ditch the M.2 form-factor, and make them PCIe add-in cards. This would remove the need for cartoonishly disproportionate cooling solutions with high-pitched 20 mm fans; and rather allow SSD designers to use cooling solutions resembling those of graphics cards. Gen 5 NVMe controllers have a TDP of around 15 W, or roughly similar to that of a motherboard chipset. The M.2-2280 form-factor is tiny for the deployment of a sufficiently large heatsink, and so SSD designers are resorting to active cooling, using 20 mm fans that don't sound pleasant. Most single-slot VGA cooling solutions can make short work of 15 W of heat while being much quieter, some even fanless.

The Innodisk 5TG-P AIC SSD uses a PCIe Gen 5 + NVMe 2.0 SSD controller with a large passive heatsink, a PCI-Express 5.0 x4 host interface, and 32 TB of capacity. The drive runs entirely on slot power, and besides the 3D TLC NAND flash, uses a large DDR4 DRAM cache. The company claims sequential transfer speeds of up to 13 GB/s in either direction. Innodisk is targeting the PCIe 5TG-P at workstation and HEDT use-cases. The company is building them in server-relevant form-factors such as U.2 and E.1S. A CDM screenshot shows 13.62 GB/s sequential reads, with 11.55 GB/s sequential writes.

Patriot Memory introduced some truly unique memory and storage products at the 2023 Computex. The company showed us what is probably the world's first PCIe Gen 5 NVMe SSD with a DRAMless architecture. It also runs surprisingly cool for the kind of performance that's being claimed. The untitled Patriot Gen 5 SSD uses a Maxiotek MAP802A-F1C DRAMless controller that features a PCI-Express 5.0 x4 host interface. The drive comes in capacities of 1 TB, 2 TB, and 4 TB. The performance on offer easily matches or beats some of the early Gen 5 SSDs based on Phison E26. You get sequential speeds of up to 12 GB/s, with up to 10.5 GB/s sequential writes.

The company also showcased the Viper PV553, a more traditional Gen 5 SSD that uses a DDR4-based DRAM cache that can be as large as 4 GB for the 2 TB model. At this point we don't know which controller is powering this drive, but it's confirmed that it uses a DRAM cache, and needs active cooling. The performance on offer is up to 12.4 GB/s sequential reads, with up to 11.8 GB/s sequential writes. A side-effect of Gen 5 SSDs picking up traction in the market is that Gen 4 SSDs with fairly powerful specs are taking up mainstream pricing. The Viper VP4300 Lite is one such drive, it is a revision of the VP4300 from 2021. This drive uses an InnoGrit-sourced controller paired with 3D TLC NAND flash, DDR4 DRAM cache, and sequential transfer speeds of up to 7.4 GB/s reads, with up to 6.8 GB/s writes. It comes in 500 GB thru 4 TB capacities, and unlike the original VP4300, lacks a heatsink.

Mushkin at the 2023 International CES showed off its Vortex Redline and Vortex LX M.2 NVMe SSDs. The Vortex Redline is the company's top PCIe Gen 4 drive, combining an Innogrit IG5236 NVMe 1.4 controller with 3D TLC NAND flash, to offer transfer speeds of up to 7415 MB/s. The Vortex Redline comes in capacities of 512 GB, 1 TB, and 2 TB. The Vortex LX is a more value-oriented product, based on an unnamed Innogrit-sourced DRAMless controller. This drive features a PCIe Gen 4 interface, but offers slightly lower performance that the company didn't disclose.

The star attraction at the Mushkin booth was its Epsilon SSD that features a PCI-Express 5.0 x4 + NVMe 2.0 interface, a Phison E26-series controller, and next generation 3D NAND flash memory (possibly 232-layer). The drive features active cooling from a fan-heatsink, and while the company didn't talk about performance, drives based on this controller are known to offer up to 12 GB/s of sequential transfers. Lastly, the company showed off its lineup of 2.5-inch SATA 6 Gbps SSDs in capacities ranging all the way up to 16 TB, which are meant to be HDD replacements, and "warm" storage devices.

Patriot Memory showed off its fastest gaming PC storage solutions at the 2023 International CES. The star attraction is an unnamed prototype M.2 PCIe Gen 5 NVMe SSD which features active cooling. This is actually the second Gen 5 SSD we've come across today that has active cooling, signaling that future NVMe SSDs are about to get hot. The ES drive comes in capacities ranging between 1 TB to 4 TB, features a PCI-Express 5.0 x4 interface with NVMe 2.0 protocol, an unknown controller+flash combination, and claimed performance of up to 12 GB/s sequential reads, with up to 10 GB/s sequential writes.

Among the other internal drives shown are the Viper P450, a Gen 4 NVMe drive offering sequential speeds of up to 7 GB/s and up to 6 GB/s writes; and capacities ranging between 512 Gb to 2 TB; a more cost-effective VPR450 drive based on a DRAMless Phison Gen 4 controller offering up to 6 GB/s reads and up to 5 GB/s writes. The Viper VXD is an external SSD enclosure meant for M.2-2280 PCIe SSDs. It offers a USB-C connection, which connects to a Realtek RTL9210B chip that converts a 10 Gbps USB 3.2 Gen 2 uplink to a PCI-Express 3.0 x4 downlink, offering sequential transfer rates of up to 1 GB/s.

Netac over the weekend released the NV5000-t, an M.2 NVMe SSD that takes advantage of the PCI-Express 4.0 x4 host interface, offering mid-range performance. Available in 500 GB and 1 TB capacities, the drive uses an unspecified type of 3D NAND flash memory, and a DRAMless controller design. On offer, are sequential transfer rates of up to 4800 MB/s reads, with up to 4600 MB/s writes for the 1 TB variant. The 500 GB variant writes sequentially at speeds of up to 2700 MB/s, but with the same up to 4800 MB/s reads. The 1 TB variant offers endurance of 640 TBW, while the 500 GB variant does 320 TBW. Both models are backed by 5-year warranties. The company didn't reveal pricing.

Kingston released the NV2 line of entry-level M.2 NVMe SSDs succeeding the NV1 series from early-2021, which was infamous for its hardware-specs lottery. The biggest change with the NV2 series is the move to PCI-Express Gen 4 (from Gen 3 for the NV1 series), even though it doesn't appear like they can take advantage of all that bandwidth.

The Kingston NV2 comes in capacities of 250 GB, 500 GB, 1 TB, and 2 TB; and offer sequential transfer speeds of up to 3000 MB/s reads, with up to 1300 MB/s writes; with endurance ratings of up to 80 TBW for 250 GB, 160 TBW for 500 GB, 320 TBW for 1 TB, and 640 TBW for 2 TB. The company won't mention the controller + NAND flash combo in use (so it could use whatever combination it wants to in the future, as long as the advertised speeds and endurance are achieved); but in all likelihood, this is Phison E19T DRAMless controller that features PCI-Express 4.0 x4, paired with 3D QLC NAND flash. Kingston is backing these with 3-year warranties.

Transcend rolled out the SSD225S, a 2.5-inch SATA client-SSD offering high endurance. The drive is available in 250 GB, 500 GB, 1 TB, and 2 TB variants, with the highest capacity offering an endurance of 720 TBW. The 1 TB variant offers 360 TBW, the 500 GB variant offers 180 TBW, and the 250 GB variant 90 TBW. Taking advantage of the SATA 6 Gbps interface, the drive offers up to 560 MB/s of sequential reads, up to 500 MB/s of sequential writes, and up to 80,000 IOPS 4K random access. The company didn't mention the NAND flash type, or controller make, but that it is DRAMless, offers SLC caching, LDPC, wear-leveling, and DEVSleep. Transcend is backing these with 3-year warranties.

PC OEMs have revealed to market intelligence firm Trendfocus that Microsoft wants them to stop the use of hard-disk drives (HDDs, or mechanical hard-drives) as the main boot device in products powered by Windows 11, from 2023. It's not known how the company will go about enforcing this. One theory holds that it may amend the Minimum System Requirements for the operating system to specify a flash-based storage device, such as an SSD. If push comes to shove, the OS could even refuse to deploy on a machine with an HDD as the boot device.

What's also not known is how this affects SSHDs (hard drives with tiny flash-based storage media and an access-based data-juggling mechanism). Microsoft's decision should come as a boon for entry-level notebook and desktop buyers; as this segment sees OEMs use HDDs as the boot device, the most. There could be a push toward at least DRAMless QLC SSDs, or even single-chip SSDs. Regardless, it's clear that 2.5-inch HDDs are on their way out of the industry. HDD as a technology may still exist in the 3.5-inch form-factor, as they are in high demand from the data-center and surveillance markets as cold storage devices.

Patriot has seemingly gone the ADATA way in changing components for at least one of its SSD products without updating the relevant documentation. The move in question affects Patriot's VPN100 SSD in its 2 TB capacity - it is currently unclear if there have been any more changes to that particular SSD stack or others in Patriot's portfolio. According to reddit user Hexagonian, he was surprised to open up his brand new Patriot VPN100 2 TB SSD to find that the components listed in Patriot's documentation don't fit at all with what's actually packaged in the SSD solution. Namely, Patriot's documentation clearly lists a Phison E12 controller paired with 2 GB of DRAM cache. However, the Patriot VPN100 user Hexagonian received featured the Phison E12S controller alongside just 1/4 of the announced DRAM cache, at 512 MB.

The SSD market in particular has been shaken by some companies silently changing their component choice for particular products. These changes are not that uncommon, mind you; especially due to the logistics and supply constraints that we are still getting out of on account of the pandemic, it's understandable that manufacturers replace some of the originally selected components with others that have either reduced pricing, higher availability, and so on. However, these decisions are particularly egregious when these changes have relevant impact on a product's performance. ADATA was one of the first SSD manufacturers caught red-handed in this game of component replacement. It's interesting how these component changes have never served to improve characteristics of these hardware pieces, however; changes have always seemingly pointed towards lower manufacturing costs whilst the end-user pricing remains the same.

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.
