The first reviews of Silicon Motion's new PCIe 5.0 NVMe SSD controller, the SM2508 are starting to appear online, and the good news is that the controller is as power efficient as promised by the company. Tom's hardware has put up their review of a reference design M.2 SSD from Silicon Motion and in their testing, equipped with 1 TB of Kioxia's 162-layer BiCS6 TLC NAND. It easily bests the competition when it comes to power efficiency. In their file copy test, it draws nearly two watts less than its nearest competitor and as much as three watts less than the most power hungry drive. It's still using about one watt more than the best PCIe 4.0 drives, but it goes to show that the production nodes matters, as the SM2508 is produced on a 6 nm node, compared to 12 nm for Phison's E26.

We should point out that the peak power consumption did go over nine watts, but only one of the Phison E26 drives managed to stay below 10 watts here. The most power hungry PCIe 5.0 SSD controller in the test, the InnoGrit IG5666 peaks at nearly 14 watts for comparison. Idle power consumption of the SM2508 is also very good, still drawing more than the PCIe 4.0 drives it was tested against, but far less than any of the other PCIe 5.0 drives. What about performance you ask? The reference drive places itself ahead of all the Phison E26 drives when it comes to sequential file transfers, regardless if it's to or from the drive. Random read IOPS also places right at the top, but it's somewhat behind when it comes to random writes, without being a slow drive by any means. Overall we're looking at a very promising new SSD controller from Silicon Motion with the SM2508 and TPU has also received a sample that is currently undergoing testing, so expect a review here soon.

Phison, a global leader in NAND controllers and storage solutions, is set to showcase its cutting-edge technologies at the Future of Memory and Storage (FMS) 2024. The event will highlight the new Pascari D-Series D200V, a datacenter SSD with up to 61.44 TB alongside the latest capabilities of aiDAPTIV+ Pro Suite, the company's end-to-end on-premises generative AI solution. Each solution is purpose-built to meet the demands of modern, data-intensive workloads, from small to medium-sized businesses looking to leverage GenAI through aiDAPTIV+, to enterprises scaling quickly with Pascari Data Center storage. These solutions allow users the necessary storage, scalability and processing power for data-hungry AI workloads.

The Pascari D200V is the latest addition to Phison's renowned D-Series product family. This SSD is designed for data centers and comes in the most popular form factors. "Pascari's new D200V scales to 61.44 TB today with Kioxia BiCS FLASH generation 8 QLC flash memory," says K.S. Pua, CEO of Phison Electronics. "The D-Series also allows room to scale beyond 100 TB, providing data centers with the large capacity options needed to reduce operating costs."

Silicon Motion's SM2508 was first revealed in August last year at the Flash Memory Summit 2023, but after that things went pretty quiet. However, the company was demoing the SM2508 up and running at Computex this past week and it's set to edge out Phison's E26 Max14um in the battle of fastest NVMe SSD controller. We're not talking about any massive gains here, but the reference drive from Silicon Motion was shown running CrystalDiskMark 8.0.4 at the show and if we do a rough comparison to a Phison E26 Max14um, the SM2508 beats Phison by about 800 MB/s in sequential read performance and 500 MB/s in sequential write performance.

This might not seem like a whole lot, but the SM2508 is built on TSMC's N6 node which results in a 3.5 Watt peak power consumption, or 7 Watts for the entire SSD at load. A typical Phison E26 based SSD draws in excess of 11 Watts of power at full load, which is a big difference in a mobile device. This should obviously also lead to lower thermals and we should finally see PCIe 5.0 drives that don't need massive heatsinks or active cooling. In fact, 7 Watts power draw is very similar to Phison's E18 PCIe 4.0 based SSDs. Silicon Motion is still working on fine tuning the firmware for the SM2508, so performance might yet improve to reach the promised 14 GB/s write performance. Currently the random performance is also looking a bit on the weak side compared to Phison. According to Tom's hardware, we should see the first drives with the Silicon Motion SM2508 appear in the market sometime in Q4 this year.

MSI Spatium M580 Liquid Frozr is easily one of the most interesting SSDs we've come across in CES 2024. Picture this—an M.2-2280 SSD that has a self-contained liquid cooler, complete with a fan, radiator, a pump-block, and coolant channels. This is both cute and a little sad. M.2 SSDs were supposed to stay out of sight and be completely cable-free, like DIMMs. This isn't MSI's fault, they have to use the fastest controllers in the market, which are built on older 12 nm foundry nodes. PCI-Express 5.0 x4 is comparable bandwidth to PCI-Express 3.0 x16, and moving this kind of data is bound to generate heat for an SSD controller. Enough banter—the Spatium M580 uses the fastest Phison E26 Max14um controller, with Micron's fastest B58R 232-layer 3D NAND flash chips that deliver 2400 MT/s per flash channel.

The combination of Phison Max14um and B58R results in sequential transfer speeds beyond the 14 GB/s mark, which is where most PCIe Gen 5 x4 drives will end up accounting for the interface+protocol overhead. The theoretical max bandwidth of Gen 5 x4 is 16 GB/s. The drive comes in capacities of up to 4 TB. As for the cooler's design, the bare drive makes contact with a copper cold-plate, which has the block+reservoir, with a tiny pump. This sends coolant through a real aluminium heat-exchanger—this is probably the smallest radiator we've ever seen. The radiator is held up, a supporting structure has a tiny 20 mm lateral-flow fan, which blows air through the radiator. We can't wait to review this thing!

Patriot Memory brought their latest ware to the 2024 International CES that use recent advancements in tech on both the SSD and memory fronts. On the SSD front, this year sees 14 GB/s capable PCIe Gen 5 NVMe SSDs thanks to Phison's E26 Max14um controller; and a new crop of USB4 portable SSDs; while the memory front sees DDR5 speeds go far north of DDR5-6000, thanks to on-module CKDs. Patriot showed us examples of each.

First up, there's the Patriot Viper PV573 Gen 5 NVMe SSD. This thing comes in capacities of up to 4 TB, and combines a Phison E26 Max14um controller with Micron's latest B58R TLC NAND flash chips that offer 2400 MT/s per flash channel. The controller also gets some incremental thermal optimizations, which means the cooling solution for the PV573 is a 16.5 mm-tall fan-heatsink. The drive offers up to 14 GB/s sequential reads, with up to 12 GB/s sequential writes. There's also a slightly de-rated version of this drive, the Viper PV553, which has the same combination of controller and NAND flash, but with transfer speeds of up to 12.4 GB/s reads, with up to 11.8 GB/s writes.

MSI, the world's leading gaming PC hardware brand, is excited to announce the launch of its next-gen flagship SSD, the SPATIUM M570 PRO FROZR, along with the high-performance model, SPATIUM M482, expanding its SSD product line. Featuring the revolutionary PHISON E26 PCIe Gen 5 controller paired with state-of-the-art 3D NAND flash and an innovative passive thermal solution, the SPATIUM M570 PRO FROZR introduces a new era in storage performance with lightning-fast read and write speeds of up to 12.4/11.8 GB/s.

This represents up to 1.8 times faster speeds compared to current PCIe 4.0 SSDs, accompanied by a temperature reduction of up to 20℃. The SPATIUM M482, built with high-quality, high-density 3D NAND flash, delivers top-tier performance for PCIe 4.0 with a sequential read speed of up to 7300 MB/s. Both models deliver a supremely responsive experience, gaining valuable milliseconds in latency for gameplay or processing gigabytes of files for professionals, content creators, and gamers. Performance-enhancing technologies include a DRAM cache buffer for M570 PRO, and a SLC cache for all announced models, supporting a comprehensive range of data error correction features including LPDC ECC and E2E Data Protection. These SSDs offer a high TBW (Terabytes Written) for excellent durability and longevity backed with a limited 5-year warranty.

The advent of PCIe 5.0 SSDs with Phison's E26 controllers has been a double-edged sword. While these SSDs offer impressively high data throughputs, they come with a significant drawback: severe overheating issues that can cause the SSDs not only to throttle down but to shut off entirely. TechPowerUp first noted this issue back in May, in our Corsair MP700 review, where the uncooled drive shut down after 86 seconds of reads and after 55 seconds of writes. Regarding criticism from tech reviewers, Corsair has released a firmware update (version 22.1) for its MP700 SSD to ensure that it throttles down rather than shutting off when overheated. Yet, many other SSDs like the Crucial T700, Seagate FireCuda 540, Gigabyte Aorus Gen 5 10000, and ADATA Legend 970 still suffer from temperature issues.

However, it's crucial to note that these extreme overheating problems occur only when the SSDs run without any cooling. While some manufacturers have planned firmware updates to address the issue, Corsair is the only company that has taken tangible action so far. Crucial has released a new firmware (PACR5102), but the ComputerBase report indicates that the SSD continues to shut off at high temperatures. The problem, though, can generally be mitigated with proper cooling. Whether using the included cooler or placing the SSD under a motherboard cover, temperatures usually stay below the critical limit, thus avoiding a complete shutdown. When we tested the SSTC Tiger Shark Elite 2 TB with Phison E26 (with updated firmware) without adequate cooling, the SSD continued to operate and throttled down, indicating that the remaining SSDs using this controller need a proper firmware update that throttles the SSD instead of shutting it down.

The first batch of PCIe 5.0 NVMe SSDs didn't quite deliver on the promise of doubling performance from PCIe 4.0 NVMe SSDs, but now it appears that Sabrent has managed to work some magic with its upcoming Rocket X5 SSD. The SSD is still based on the same Phison E26 controller as all other current PCIe 5.0 NVMe drives and from what we know, the controller is paired to Micron's 232-layer B58R NAND, a combination that should be able to reach 2400 MT/s across eight channels. However, it's not the only drive with this combination of components, so it seems like the magic here might be in the firmware.

A 2 TB version of the Rocket X5 was tested in CrystalDiskMark 8.0.4 and reached a read speed of 14,179 MB/s or just over 14 GB/s, with write speeds trailing somewhat at 12,280 MB/s. The random 4K numbers are looking good too with 106 MB/s for reads and 448 MB/s for writes, a step up from the competition at least, if not a major one with regards to the read speed. The downside you ask? Sabrent has equipped the Rocket X5 with not only a heatsink and heatpipes, but also a tiny fan, which is likely to add some noise at some time in the future when the fan starts to give up. We obviously don't know the price of the Rocket X5 either, but Sabrent tends to have competitively priced products.

Essencore KLEVV brought in a formidable lineup of new PCIe Gen 5 NVMe SSDs and DDR5 memory for gamers and overclockers, at the 2023 Computex. The lineup is led by the KLEVV CRAS V RGB series of DDR5 memory that comes in high-end speeds of DDR5-6000 (30-36-36-76 @ 1.35 V), DDR5-6400 (32-38-38-78 @ 1.35 V), DDR5-7200 (34-44-44-84 @ 1.40 V), DDR5-7600 (36-46-46-86 @ 1.40 V), and DDR5-8000 (38-48-48-128 @ 1.55 V). These modules feature both Intel XMP 3.0 and AMD EXPO SPD profiles. The KLEVV BOLT V series form the company's mid-range, offering speeds of DDR5-6000 (30-36-36-76 @ 1.35 V), DDR5-6400 (32-38-38-78 @ 1.35 V), and DDR5-6800 (34-40-40-80 @ 1.35 V). Both XMP 3.0 and EXPO are to be found even with these modules. The company interestingly also has standard modules for DDR5-4800 and DDR5-5600, which make do with just 1.1 V. We also spied KLEVV's odd-capacity 24 GB and 48 GB CRAS V RGB modules.

The storage lineup for Essencore is led by the KLEVV CRAS C950 PCIe Gen 5 NVMe SSD, and the CRAS C910 Gen 4 SSD. The CRAS C950 comes in 1 TB, 2 TB, and 4 TB capacities, and uses a Phison E26-series controller paired with 3D TLC NAND flash. The 1 TB variant offers up to 11.5 GB/s sequential reads, with up to 8.5 GB/s sequential writes, while the 2 TB and 4 TB models do up to 12 GB/s sequential reads, with up to 11 GB/s sequential writes. The drive uses a chunky passive aluminium heatsink to keep cool. The CRAS C910, on the other hand, comes both as a bare drive (without heatsink), and as the CRAS C910 RGB, where it features a heatsink with an RGB diffuser. The drive uses an InnoGrit IG5220 controller, comes in capacities of up to 1 TB, and offers speeds of up to 5 GB/s sequential reads, with up to 4.8 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.

ADATA and XPG, its gamer focused sub-brand, unveiled a plethora of memory and storage products at the 2023 Computex. We begin with PC memory, and we see the company showing off its upcoming models of the XPG DDR5 memory targeting enthusiasts. These include the XPG Caster RGB DDR5, which is capable of DDR5-9000, the XPG Lancer RGB ROG edition, capable of DDR5-7200, and the company's overclocking-capable DDR5-6400 R-DIMM targeting Xeon W workstations. The company also showed us "Project NeonStorm." This is an innovative new SSD cooling system that uses a self-contained liquid cooler.

The way this liquid cooler works is that a high conductivity heat spreader transfers heat to a chamber containing a coolant fluid. This coolant heats up an aluminium alloy tube via convection. The inner wall of this tube serves as an airflow channel for a 20 mm fan. ADATA claims that this solution offers "over 20% better heat dissipation compared to SSDs without water cooling." This is also one of the very first SSDs we've seen that utilize Silicon Motion SM2508 PCIe Gen 5 NVMe controller. ADATA claims sequential reads of up to 14 GB/s, with up to 12 GB/s sequential writes. The drive comes in capacity-based models of up to 8 TB (could include 2 TB, 4 TB, and 8 TB). ADATA also showed off the Legend 970 PCIe Gen 5 NVMe SSD that uses a Phison E26-series controller, and comes in capacities of 1 TB and 2 TB. This drive belts out up to 10 GB/s reads, with up to 10 GB/s writes.

A trend we've seen in the 2023 Computex is that SSD manufacturers aren't advertising their feisty Gen 5 NVMe SSDs with the elaborate cooling solutions that they sorely need, but rather as bare drives, with the cooling options marketed separately. In practice, manufacturers could get retailers to bundle Gen 5 SSDs with a selection of their coolers. This lets them trim some of the criticism of just how hot SSDs have gotten over just one generation. Team Group showed off its T-Force Cardea Z5 lines of M.2 Gen 5 NVMe SSDs. There are two distinct lines with the same names. One of these comes with a maximum sequential read speed of 12 GB/s, while the other comes with 14 GB/s. Both have their respective 1 TB, 2 TB, and 4 TB capacity variants. Both use 3D TLC NAND flash. The under-the-hood difference between the 12 GB/s and 14 GB/s versions of the Cardea Z5 is that while the 12 GB/s variant uses a Phison E26-series controller, the 14 GB/s one uses an InnoGrit IG5666 controller. Team Group intends to eventually re-brand the 14 GB/s variant as the Cardea Z54A series.

Team Group also announced a handful cooling solutions to pair with these Gen 5 SSDs. The most striking of these is the T-Force Siren, an all-in-one (AIO) closed loop liquid M.2 NVMe SSD cooler, with as 120 mm radiator. The name is a bit of a misnomer, as SSD coolers with 20 mm fans is what a siren might sound like. Obviously, this cooler is overkill, and helps the SSD deliver its best performance, but there are other options from the company. The T-Force AirFlow I uses two copper heatpipes that run through the base-plate, pulling heat from the controller, NAND flash, and DRAM, and pushing it through an aluminium fin-stack arranged vertically. This is then ventilated by a 30 mm fan. The T-Force Airflow II uses a slightly different approach, with a single thicker heat pipe arranged in a C-shape, with radially-projecting finnage that have the appearance of a cylinder. At the other end of this is a 30 mm fan.

Crucial T700, the company's flagship M.2 NVMe Gen 5 SSD, runs hot—like every other drive based on the Phison E26-series controller (such as the Corsair MP700). ComputerBase.de discovered what the drive does without some sort of cooling. The E26 controller has a Tjmax value of around 86°C, and what happens when it's reached depends on the drive in question. The Corsair MP700 can turn itself off to protect the controller—something that will definitely cause your machine to hang with a BSOD.

The Crucial T700, on the other hand, aggressively throttles down the controller in an attempt to lower temperatures. While the drive won't stop (and your machine won't hang), its performance drops to hard drive levels, with CrystalDiskMark (CDM) measurements pointing to around 101 MB/s (of course, with much lower access times than a HDD). Both Crucial and Corsair offer the drive with large heatsinks, and recommend users to use them. This should severely limit the adoption of Gen 5 NVMe SSDs among notebooks, where the notebook chassis has room for only bare drives. However, some OEMs specializing in larger high-end gaming notebooks and desktop-replacement workstations, can find ways to connect the drives to the notebook's main cooling system using flattened heatpipes. You can catch ComputerBase's review of the MP700 in the source link below.

Galax is joining the PCIe 5.0 SSD crowd with its newest HOF Extreme 50 SSD that has been launched in China, and should come to the rest of the markets soon. The Galax HOF Extreme 50 will be only available in 1 TB and 2 TB capacities, and comes with thick heatsink with active cooling via PWM fan.

As it is the case with all other PCIe 5.0 SSDs currently on the market, the HOF Extreme 50 is based on Phison E26 controller paired up with Micron 232-layer 3D NAND flash and up to 4 GB of LPDDR4 DRAM cache. The Galax HOF Extreme 50 is not the fastest Phison E26-based PCIe 5.0 SSD announced, as Gigabyte Aorus Gen 5 1000, MSI Spatium M570 Pro, and Crucial T700, are coming and reaching up to 12 GB/s (12.4 GB/s for the Crucial T700).

GIGABYTE formally launched its flagship AORUS Gen5 10000 series M.2 NVMe SSDs that take advantage of a PCI-Express 5.0 x4 interface. Currently, all AMD B650 series and X670 series motherboards offer a PCIe Gen 5 M.2 slot wired to the processor without eating into PEG bandwidth, while some Intel 700-series chipset motherboards offer Gen 5 M.2 slots by subtracting lanes from the PEG slot. AORUS Gen5 10000 for now comes in 1 TB and 2 TB capacities. The drives combine a Phison E26 series controller with 3D TLC NAND flash memory and LPDDR4 DRAM cache.

The 1 TB model offers sequential transfer speeds of up to 9.5 GB/s reads, with up to 8.5 GB/s writes, and 700 TBW endurance; whereas the 2 TB model is faster, with up to 10 GB/s sequential reads, up to 9.5 GB/s writes, and 1,400 TBW endurance. The drive's power consumption is under 10 W, and GIGABYTE has deployed a thoughtful fanless cooling solution for the drive that spares you from the annoying high-pitched noise of other upcoming Gen 5 M.2 SSDs that use fan-heatsinks. The company didn't reveal pricing, but mentioned that the drives are backed by 5-year warranties.

In Japan, the first consumer focused PCIe 5.0 NVMe SSDs have gone on sale and one of these drives has been put through some quick synthetic benchmarks by @momomo_us on Twitter. We're not familiar with the CFD Gaming brand which the drive is sold under, but the CSSD-M2M2TPG5NFZ—as the drive is called—is based on Phison's E26 controller and it's paired with Micron's B58R 3D TLC NAND, suggesting it's based around a reference design from Phison. CFD Gaming offers the drive in 1, 2 and 4 TB sizes and @momomo_us tested the 2 TB version.

Before we go into the performance figures, there's one thing that needs to be highlighted about this drive, it produces a high pitch noise during use, thanks to its tiny 17x17 mm, 21,000 rpm fan from Sunon. @momomo_us provided a video on Twitter which is linked below, so you can hear it in action for yourself. Hopefully this isn't the future of NVMe SSDs, as it's going to put off many potential customers from getting one. @momomo_us only tested the drive with CrystalDiskMark 8.0.4, which shows that sequential write speeds are slightly faster than claimed by CFD Gaming, with the sequential write speeds being bang on the money. For those hoping for higher random performance, things aren't looking so great, as the drive only performs slightly better than the best PCIe 4.0 NVMe drives.
