ADATA is tewasing at Computex with a new SSD that will benefit the bandwidth of PCI-Express gen 4.0 bus.
AMD X570 platform motherboards offer 2-3 M.2 slots with PCIe gen 4.0 x4 wiring (64 Gbps).
Based on the Silicon Motion SM2267 controller, the new ADATA drive comes in a capacity of up to 8 TB, probably using 96-layer QLC NAND flash.
The controller features DRAM cache, and dynamic SLC caching. ADATA claims sequential speeds of up to 4000 MB/s reads. Sequential writes are still up to 3000 MB/s. 4K random read/write access is rated at 400k IOPS.
