HP 1.92TB SAS SSD

This HP 875478-B21 is a 1.92TB 2.5" internal solid-state drive with a SAS interface and hot-swap capability. It is built for mixed-use workloads in compatible PC platforms. The silver SFF form factor fits standard 2.5" SATA drive bays.

Suits servers needing hot-swap SAS storage

This drive suits administrators who need a 1.92TB SAS SSD with hot-swap support for mixed read and write workloads. It is not suited for systems that only accept SATA protocol drives or lack a SAS controller. Buyers who need a different capacity or a non-hot-swap form factor should look at other models.

SAS interface decides compatibility

The single specification that decides fit is the SAS interface; the host must provide a SAS backplane or controller to operate this drive. A SATA-only backplane will not recognise the device. Verify the server or array supports SAS SSDs before purchase.

Questions about this item

How do I install the HP 875478-B21 2.5" SAS drive into a hot-swap bay?

Slide the drive into the SFF hot-swap tray until the SAS connector seats firmly; the tray latch clicks when fully engaged.

What maintenance or replacement will the 1.92TB mixed-use SSD need later?

Monitor SMART wear indicators; replace the drive once the rated write endurance for mixed-use workloads is reached.

What limit appears first on the SAS 6G interface during sustained writes?

The SAS 6G link caps sustained throughput at its 6 Gbit/s signalling rate before the NAND write path saturates.
