The new generation of PCIe 5.0 SSDs is taking shape at Adata. After prototypes, the manufacturer shows the first series product. The XPG PCIe Gen5 SSD is in M.2 format and is equipped with an SMI controller. It should read at 14 GB/s and write at 12 GB/s. Silicon Motion’s SM2508 controller is hidden under the cooler with its cooling fins and backplate.
Via the PCIe 5.0 x4 interface, which enables almost 16 GB/s gross, the XPG series SSD for gamers should sequentially read data at up to 14 GB/s and sequentially write at up to 12 GB/s. That’s pretty much double what today’s high-end PCIe 4.0 x4 SSDs achieve. Unlike the PCIe 4.0 SSD’s inception, the first products should almost reach the limit of the new interface.
XPG PCIe Gen5 SSD 4K random transfers (4K random) should be capable of peaking at 1.8 million IOPS reading and 1.6 million IOPS writing. However, experience has shown that the values are only achieved under ideal conditions in benchmarks; but it always was. The XPG PCIe Gen5 SSD should provide up to 8TB of storage, which is a lot for this size. However, a market launch with initially smaller storage capacities is likely.
Prototype “Nighthawk” goes into series production
Adata had already shown two prototypes of PCIe 5.0 SSDs at CES 2022. The “Nighthawk” variant with SM2508 controller is now being implemented in practice. It remains to be seen whether the prototype dubbed “Blackbird” with Innogrit’s IG5666 controller will also go into series production. This is not unlikely, as Adata is a third-party SSD manufacturer that is willing to experiment when using new controllers from all manufacturers.

Hardly any details about the SMI controller
There is still little information about Silicon Motion’s SM2508 controller. The only thing that is clear is that it works with PCIe 5.0 x4 and NVMe 2.0. After Silicon Motion had virtually no competitor in the PCIe 4.0 generation and had to leave the field to competitor Phison, SMI now has the opportunity to do better with PCIe 5.0 and bring a high-end product to the market. consumer market.
However, the competition never sleeps. In addition to the aforementioned Innogrit model, Phison has also developed a powerful PCIe Gen5 controller in the form of the E26. Other M.2 SSDs with PCIe 5.0 has already been shown by Apacer and Zadak. Many more are expected to follow when AMD’s new AM5 platform launches. The first AM5 motherboards with the X670(E) chipset are expected in September along with the AMD Ryzen 7000 family of CPUs. AMD provides the platform for new NVMe SSDs with PCIe 5.0
