HP 400GB SAS enterprise SSD

This HP 632636-001-R is a 2.5-inch solid-state drive built for enterprise servers and storage arrays. It provides 400GB of capacity over a SAS 6Gb/s interface using MLC memory components. The drive is supplied in refurbished condition.

Suited for servers needing reliable SAS storage

The SAS interface and MLC flash suit workloads that demand consistent write endurance and dual-port connectivity in 2.5-inch bays. Buyers who need larger capacities or a different interface should look at other models.

Steady performance under sustained load

MLC architecture helps maintain write speeds during extended operations typical of database and virtualization tasks. The SAS 6Gb/s link supports continuous data transfer without the thermal throttling seen in short bursts.

Questions about this item

Does my server need a SAS 6Gb/s backplane or HBA for this 2.5" drive to work?

Yes, the drive uses a SAS 6Gb/s interface and a 2.5" form factor, so the host system must provide a compatible SAS backplane or controller card with the correct connector.

Will this 400GB MLC SAS SSD work in a server that currently runs 3Gb/s SAS hard drives?

The drive is backward compatible with 3Gb/s SAS backplanes, but it will operate at the slower 3Gb/s link speed instead of its native 6Gb/s rate.

How can I confirm the 400GB MLC SAS SSD is healthy after installation?

Run the server firmware or OS disk utility to verify the drive reports 400GB capacity, shows a SAS 6Gb/s link speed, and passes a SMART self-test with no errors.
