Adata’s sales space at CES 2023 held just a few surprises, together with the primary SMI-powered PCIe 5.0 SSD, which peaks at a blistering 14 GB/s, a brand new CXL 1.1 DDR5 gadget, and the corporate’s new transportable SSD that gained a CES innovation award for pc peripherals. The show additionally confirmed that SMI’s PCIe 5.0 SSD controllers will likely be quicker than the Phison E26-powered fashions that can come to market over the subsequent few months.
Adata was one of many early SSD pioneers and has a historical past of utilizing practically each kind of SSD controller out there. Nevertheless, as a result of Silicon Movement’s future 2508 controller remains to be far off on the horizon, it was shocking to see the height speeds it will probably obtain with Adata’s configuration. The preview offers a great view of how PCIe 5.0 SSDs apart from these powered by Phison’s E26, which dominates the present crop of recent PCIe 5.0 drives, will carry out.
The 12nm Silicon Movement (SMI) SM 2508 SSD controller powers Adata’s as-yet unbranded ‘XPG PCIe GEN5 SSD.’ The drive affords as much as 14 GB/s of sequential learn throughput, saturating the PCIe 5 bus, and 12 GB/s of sequential write throughput, 200 MB/s quicker than SSDs powered by the E26.
Adata additionally claims that its drive will serve up 2 million random learn/write IOPS, beating the Phison E26 by half 1,000,000 IOPS in random write workloads. This stage of efficiency is especially spectacular on condition that the SM 2508 is simply a four-channel controller, whereas the E26 is an eight-channel controller.

Adata plans to subject as much as 8TB SSDs with the controller however hasn’t specified which kind of NAND it used to succeed in this stage of efficiency. Nevertheless, the corporate will qualify a number of sorts of NAND with the controller.
The M.2 bus now helps as much as 11.5W of energy to an M.2 SSD, and we anticipate that PCIe 5.0 SSDs will start to push as much as these increased energy limits. PCIe 5.0 SSDs will want beefier cooling to ship the utmost efficiency, and now we’re additionally seeing loads of indicators that lively cooling will likely be required for high-powered fashions, similar to the early Phison E26 pattern we not too long ago examined.
Adata’s SMI-powered SSD could have an built-in fan constructed proper into the heatsink, however though a majority of these small followers usually produce a high-pitched whine, Adata says the noise stage is negligible. That is sensible on condition that the fan is nestled beneath an higher masking that has an air channel with openings at both finish, as you’ll be able to see within the photos above. That ought to comprise any significant noise from the fan.
Adata additionally touts that the heatsink is the ‘world’s first’ to make use of a crystallization remedy that purportedly lowers temperatures and helps with thermal dissipation. This drive is sandwiched between the heatsink and a stainless-steel base plate (the baseplate and heatsink latch collectively).
We’re wanting ahead to placing the drive to the check, however Adata isn’t able to remark but on last specs, pricing, or availability. We adopted up with SMI representatives who inform us that they anticipate the controller to be in mass manufacturing in early 2024, so it appears to be like like Adata’s SSD will likely be a bit additional out on the horizon than anticipated. SMI may also convey a cut-down four-channel model of the SM2508, the SM 2507, to market in 2024. In the meantime, SMI has its full-featured 16-channel MonTitan PCIe 5.0 x8 SSD controller sampling to knowledge middle clients, with full manufacturing to start this quarter.

We additionally noticed Adata’s new CXL 1.1 reminiscence module, which may come packing as much as 512GB of DDR5 reminiscence that communicates over a PCIe 5.0 x4 bus. This module comes within the ES.3 type issue, so it will probably plug into preparations just like the two.5″ NVMe drive bays you see on the entrance of a server or into custom-built backplanes inside a separate chassis.
A single RISC-V powered Montage MXC (M88MX5891) CXL reminiscence expander ties the banks of DDR5 reminiscence collectively, permitting 32, 64, 128, 256, or 512GB of DRAM to be positioned on a single gadget that’s roughly the scale of a 2.5″ U.2 SSD. The controller helps the CXL 1.1 and a pair of.0 RAS spec, with CXL.mem and CXl.io protocols on the menu for reminiscence enlargement.
Compute Categorical Hyperlink (CXL) units enable server processors to deal with locally-placed reminiscences, DDR5 on this case, as native reminiscence. The everyday latency affect weighs in round that of an ordinary NUMA hop, so it’s completely tenable for a lot of sorts of workloads that prize further reminiscence capability. Adata is able to produce these drives as we speak with numerous flavors of reminiscence, however they’re reserved for {custom} orders for big hyperscalers and the like, so you will not see them at retail. You possibly can learn all the nitty-gritty particulars of the CXL spec right here.
AMD’s EPYC Genoa and Intel’s Sapphire Rapids each assist CXL, so we should always anticipate a majority of these units to search out loads of customers over the approaching years.

Adata’s SE920 picked up a CES award on the present. The gadget has a USB4 interface that operates at 40Gbps. An Asmedia ASM2464PD controller powers the drive to ship as much as 3,800/3,2000 MB/s of sequential learn/write throughput.
The quilt is slidable, and the drive can perform in both the closed format (first and second photos) or be expanded to open up a bigger recess in the midst of the drive (third and fourth pics). Increasing the drive opens up the air channels in the midst of the gadget and engages a small inside fan (not seen right here) that cools the gadget by expelling air via the small holes on the high of the gadget. That is helpful throughout lengthy file transfers that require the utmost efficiency. The drive connects to the host by way of a USB-C connection.
The SE920 will retail for roughly $150 to $170 for the 1TB mannequin and $300 for the 2TB mannequin. We are able to anticipate to see them on cabinets earlier than the tip of April.
