2.5 inch SAS enterprise SSD in silver metal caddy tray

Seagate

Seagate HUSMM1640ASS200 400GB 12Gbps 2.5" SAS enterprise SSD

SKU CH-7CZA-9CZW3

400 GB enterprise SAS SSD with 12 Gbps interface, hot-swap 2.5" form factor and included system caddy

  • 400GB capacity supports demanding enterprise workloads
  • 12Gbps SAS interface delivers high-throughput data transfer
  • 5 inch form factor fits standard server bays
  • MLC NAND provides consistent write endurance
  • Includes SYSTEM X caddy for hot-swap installation

Enterprise SAS SSD with included caddy

The Seagate HUSMM1640ASS200 is a 400GB enterprise solid-state drive built for 2.5in SAS 12Gbps bays. It uses MLC flash and ships new with an IBM System X caddy for direct hot-swap installation in compatible servers.

Fits 12Gbps backplanes and frees PCIe slots

The drive connects through a 12Gbps SAS interface on a standard 2.5in form factor, so it slots into existing drive trays without an adapter. Using the SAS backplane leaves PCIe lanes available for other expansion cards such as GPUs or network controllers.

Steady write throughput under sustained load

MLC memory and the 12Gbps SAS link maintain consistent performance during long write sequences rather than throttling after a short burst. The included tray ensures secure seating in hot-swap bays for continuous operation in array rebuilds or logging workloads.

Questions about this item

What is the sustained write limit before the 400 GB MLC drive throttles?

The drive uses MLC NAND rated for enterprise endurance; exact sustained write limits are defined by the manufacturer's specification sheet for the HUSMM1640ASS200.

How much heat and noise does the 2.5-inch SAS SSD produce in a hot-swap bay under continuous load?

The solid-state design has no moving parts, so it generates minimal acoustic noise; thermal output is managed by the server's airflow across the 2.5-inch form factor.

Which server backplane and caddy are required to install this 12 Gbps SAS drive?

The package includes an IBM System x hot-swap caddy; the drive needs a 12 Gbps SAS backplane with 2.5-inch drive bays.
