Samsung announced a solid state drive with an E1.S form factor and full PCIe Gen 4 support.
The new drive, which leverages the production efficiencies of the company’s sixth-generation (1xx-layer), three-bit V-NAND, uses the new form factor to maximize the number of drives possible in a 1-RU chassis.

The newly announced PM9A3 drive, to be available in three versions, is expected to feature a PCIe Gen 4 (x4) interface for more than twice the sequential read performance of PCIe Gen 3 (3200MB/s), and include dedicated hardware accelerators for nearly twice the random writes (180,000 IOPs) of the previous generation. Capacities will range from 960 GB to 7.68 TB.
