Adata Reveals Gen5 SSD with up to 14 GB/s and 8 TB Storage

The XPG PCIe Gen5 SSD should read and write at 14 GB/s and 12 GB/s respectively.

Adata is working on the new 5th generation PCIe 5.0 SSDs as it shows off the XPG Gen5 PCIe M.2 SSD. It's supposedly capable of reading at 14GB/s and writing at 12GB/s, and uses Silicon Motion's SM2508 controller with its backplate and cooling.

Putting it into perspective

The PCIe 5.0 x4 interface allows nearly 16GB/s speeds, which is close to the numbers on the XPG Gen5 SSD, i.e 14GB/s Read and 12GB/s Write.

To put this into perspective, the Samsung 980 PRO is delivering nearly 7,000 MB/s Read speeds with a PCIe 4.0 interface. While the PCIe Gen 3 has a max speed of 958MB/s per lane, making it a total of almost 4GB/s for 4 lanes (PCIe 3 x4). A typical SATA3 SSDs runs just under 600MB/s.

Random Transfers

The 4K random transfers (4K random) on the XPG PCIe Gen5 SSD should be able to hit 1.8 million IOPS in Read and 1.6 million IOPS in Write. However, these numbers are normally only achieved under ideal conditions in benchmarks, but of course that's not just the case with this particular product.

Storage Space

The XPG PCIe Gen5 SSD will supposedly launch with up to 8TB in storage capacity, and that's a lot of storage space. Although it's likely to have other smaller capacity variants too.
