At the recently-held Open Compute Project Virtual Global Summit, Samsung announced that it has developed a new PM9A3 datacentre SSD lineup, including one version that’s based on the E1.S form factor.

Designed to optimise storage deployments in modern datacentres where the use of enterprise-level SSDs isn’t ideal (even when they’re using the M.2 or U.2 form factor), the new E1.S SSD supports the x4 interface and PCIe Gen 4 (using the NVMe protocol) and can fit vertically in a 1U enclosure.

For datacentres that are now using M.2 SSDs, this E1.S form factor is a natural upgrade: it supports higher power but is also easier to cool. It also enables the datacentres to add more SSDs per server.

Also available in U.2 and M.2 form factors, the PM9A3 drive offers a top sequential read and write speeds of up to 6,500MB/s and 3,500MB/s respectively. Random read and write speeds also top out at 900,000 IOPS and 180,000 IOPS respectively.
