Enterprise 400GB SAS SSD

This IBM HUSMM1640ASS200 is a 400GB 2.5-inch enterprise solid-state drive built for 12Gbps SAS infrastructure. It ships new with a Storwize V5030 caddy for direct installation in compatible IBM storage arrays.

12Gbps SAS interface limit

The drive connects through a 12Gbps SAS link, so throughput cannot exceed that bus speed. Systems limited to 6Gbps SAS will operate at the lower rate, and non-SAS backplanes cannot accept the drive at all.

400GB capacity headroom

At 400GB the drive suits read-intensive workloads such as boot volumes, caching tiers or metadata storage. Write-heavy databases or large sequential archives will exhaust the available space quickly, requiring additional drives.

Questions about this item

Should I choose the 400GB capacity for write-heavy workloads?

The 400GB capacity with MLC flash is built for mixed read-write workloads in Storwize V5030 arrays.

What does the 12Gbps SAS link deliver inside a Storwize V5030?

The 12Gbps SAS interface provides full dual-port bandwidth to the controller, removing the interface bottleneck for this drive.

Does the 2.5" SAS 12Gbps interface limit performance in a 6Gbps backplane?

The drive negotiates down to 6Gbps on older backplanes, capping throughput at the lower link speed.
