Hand-held gaming consoles based on notebook platforms (such as the Valve SteamDeck, ASUS ROG Ally, and the MSI Claw) are one of the fastest growing segments in the PC gaming market. The form-factor of such systems has created a demand for M.2 2230 NVMe SSDs. Almost all vendors have a play in this market, and even Micron has OEM SSDs (such as the Micron 2400, 2550, and 2500 series) in this form-factor. Crucial has strangely not had an offering with its own brand name to target this segment, but that changes today with the launch of the Crucial P310 NVMe SSD.
The Crucial P310 is a family of M.2 2230 PCIe Gen4 NVMe SSDs boasting class-leading read/write speeds of 7.1 GBps and 6 GBps. The family currently has two capacity points - 1 TB and 2 TB. Micron claims that the use of its 232L 3D NAND and Phison's latest E27T DRAM-less controller (fabricated in TSMC's 12nm process) help in reducing power consumption under active use compared to the competition - directly translating to better battery life for the primary use-case involving gaming handheld consoles.
Based on the specifications, it appears that the drives are using 232L 3D QLC. Compared to the recently-released Micron 2550 SSD series in the same form-factor, a swap in the controller has enabled some improvements in both power efficiency and performance. The other specifications are summarized in the table below.

The power efficiency, cost, and capacity points are plus points for the Crucial P310 family. However, the endurance ratings are quite low. Gaming workloads are inherently read-heavy, and this may not be a concern for the average consumer. However, a 0.12 DWPD rating may turn out to be a negative aspect when compared against the competition's 0.33 DWPD offerings in the same segment.
StorageSamsung Validates LPDDR5X Running at 10.7 GT/sec with MediaTek's Dimensity 9400 SoC Samsung has successfully validated its new LPDDR5X-10700 memory with MediaTek's upcoming Dimensity platform. At present, 10.7 GT/s is the highest performing speed grade of LPDDR5X DRAM slated to be released this year, so the upcoming Dimensity 9400 system-on-chip will get the highest memory bandwidth available for a mobile application processor. The verification process involved Samsung's 16 GB LPDDR5X package and MediaTek's soon-to-be-announced Dimensity 9400 SoC for high-end 5G smartphones. Usage of LPDDR5X-10700 provides a memory bandwidth of 85.6 GB/second over a 64-bit interface, which will be available for bandwidth-hungry applications like graphics and generative AI. "Working together with Samsung Electronics has made it possible for MediaTek's next-generation Dimensity chipset to become the world's first to be validated at LPDDR5X operating speeds up to 10.7Gbps, enabling upcoming devices to deliver AI functionality and mobile performance at a level we have never seen before," said JC Hsu, Corporate Senior Vice President at MediaTek. "This updated architecture will make it easier for developers and users to leverage more AI capabilities and take advantage of more features with less impact on battery life." Samsung's LPDDR5X 10.7 GT/s memory in made on the company's 12nm-class DRAM process technology and is said to provide a more than 25% improvement in power efficiency over previous-generation LPDDR5X, in addition to extra performance. This will positively affect improved user experience, including enhanced on-device AI capabilities, such as faster voice-to-text conversion, and better quality graphics. Overall, the two companies completed this process in just three months. Though it remains to be seen when smartphones based on the Dimensity 9400 application processor and LPDDR5X memory are set to be available on the market, as MediaTek has not yet even formally announced the SoC itself. "Through our strategic cooperation with MediaTek, Samsung has verified the industry's fastest LPDDR5X DRAM that is poised to lead the AI smartphone market," said YongCheol Bae, Executive Vice President of Memory Product Planning at Samsung Electronics. "Samsung will continue to innovate through active collaboration with customers and provide optimum solutions for the on-device AI era." Memory
Samsung Joins The 60 TB SSD Club, Looking Forward To 120 TB Drives Multiple companies offer high-capacity SSDs, but until recently, only one company offered high-performance 60 TB-class drives with a PCIe interface: Solidigm. As our colleagues from Blocks & Files discovered, Samsung quietly rolled out its BM1743 61.44 TB solid-state drive in mid-June and now envisions 120 TB-class SSDs based on the same platform. Samsung's BM1743 61.44 TB features a proprietary controller and relies on Samsung's 7th Generation V-NAND (3D NAND) QLC memory. Moreover, Samsung believes that its 7th Gen V-NAND 'has the potential to accommodate up to 122.88 TB,' Samsung plans to offer the BM1743 in two form factors: U.2 for PCIe 4.0 x4 to address traditional servers and E3.S for PCIe 5.0 x4 interfaces to address machines designed to offer maximum storage density. BM1743 can address various applications, including AI training and inference, content delivery networks, and read-intensive workloads. To that end, its write endurance is 0.26 drive writes per day (DWPD) over five years. Regarding performance, Samsung's BM1743 is hardly a champion compared to high-end drives for gaming machines and workstations. The drive can sustainably achieve sequential read speeds of 7,200 MB/s and write speeds of 2,000 MB/s. It can handle up to 1.6 million 4K random reads and 110,000 4K random writes for random operations. Power consumption details for the BM1743 have not been disclosed, though it is expected to be high. Meanwhile, the drive's key selling point is its massive storage density, which likely outweighs concerns over its absolute power efficiency for intended applications, as a 60 TB SSD still consumes less than multiple storage devices offering similar capacity and performance. As noted above, Samsung's BM1743 61.44 TB faces limited competition in the market, so its price will be quite high. For example, Solidigm's D5-P5336 61.44 TB SSD costs $6,905. Other companies, such as Kioxia, Micron, and SK Hynix, have not yet introduced their 60TB-class SSDs, which gives Samsung and Solidigm an edge for now. UPDATE 7/25: We removed mention of Western Digital's 60 TB-class SSDs, as the company does not currently list any such drives on their website SSDs
G.Skill on Tuesday introduced its ultra-low-latency DDR5-6400 memory modules that feature a CAS latency of 30 clocks, which appears to be the industry's most aggressive timings yet for DDR5-6400 sticks. The modules will be available for both AMD and Intel CPU-based systems.
With every new generation of DDR memory comes an increase in data transfer rates and an extension of relative latencies. While for the vast majority of applications, the increased bandwidth offsets the performance impact of higher timings, there are applications that favor low latencies. However, shrinking latencies is sometimes harder than increasing data transfer rates, which is why low-latency modules are rare.
Nonetheless, G.Skill has apparently managed to cherry-pick enough DDR5 memory chips and build appropriate printed circuit boards to produce DDR5-6400 modules with CL30 timings, which are substantially lower than the CL46 timings recommended by JEDEC for this speed bin. This means that while JEDEC-standard modules have an absolute latency of 14.375 ns, G.Skill's modules can boast a latency of just 9.375 ns – an approximately 35% decrease.
G.Skill's DDR5-6400 CL30 39-39-102 modules have a capacity of 16 GB and will be available in 32 GB dual-channel kits, though the company does not disclose voltages, which are likely considerably higher than those standardized by JEDEC.
The company plans to make its DDR5-6400 modules available both for AMD systems with EXPO profiles (Trident Z5 Neo RGB and Trident Z5 Royal Neo) and for Intel-powered PCs with XMP 3.0 profiles (Trident Z5 RGB and Trident Z5 Royal). For AMD AM5 systems that have a practical limitation of 6000 MT/s – 6400 MT/s for DDR5 memory (as this is roughly as fast as AMD's Infinity Fabric can operate at with a 1:1 ratio), the new modules will be particularly beneficial for AMD's Ryzen 7000 and Ryzen 9000-series processors.
G.Skill notes that since its modules are non-standard, they will not work with all systems but will operate on high-end motherboards with properly cooled CPUs.
The new ultra-low-latency memory kits will be available worldwide from G.Skill's partners starting in late August 2024. The company did not disclose the pricing of these modules, but since we are talking about premium products that boast unique specifications, they are likely to be priced accordingly.
MemoryMicrochip recently announced the availability of their second PCIe Gen 5 enterprise SSD controller - the Flashtec 5016. Like the 4016, this is also a 16-channel controller, but there are some key updates:
Microchip's enterprise SSD controllers provide a high level of flexibility to SSD vendors by providing them with significant horsepower and accelerators. The 5016 includes Cortex-A53 cores for SSD vendors to run custom applications relevant to SSD management. However, compared to the Gen4 controllers, there are two additional cores in the CPU cluster. The DRAM subsystem includes ECC support (both out-of-band and inline, as desired by the SSD vendor).
At FMS 2024, the company demonstrated an application of the neural network engines embedded in the Gen5 controllers. Controllers usually employ a 'read-retry' operation with altered read-out voltages for flash reads that do not complete successfully. Microchip implemented a machine learning approach to determine the read-out voltage based on the health history of the NAND block using the NN engines in the controller. This approach delivers tangible benefits for read latency and power consumption (thanks to a smaller number of errors on the first read).
The 4016 and 5016 come with a single-chip root of trust implementation for hardware security. A secure boot process with dual-signature authentication ensures that the controller firmware is not maliciously altered in the field. The company also brought out the advantages of their controller's implementation of SR-IOV, flexible data placement, and zoned namespaces along with their 'credit engine' scheme for multi-tenant cloud workloads. These aspects were also brought out in other demonstrations.
Microchip's press release included quotes from the usual NAND vendors - Solidigm, Kioxia, and Micron. On the customer front, Longsys has been using Flashtec controllers in their enterprise offerings along with YMTC NAND. It is likely that this collaboration will continue further using the new 5016 controller.
