3 TB SAS hard drive for servers
This HP 625031-B21 is a 3 TB, 7200 RPM SAS 6Gb/s 3.5-inch internal hard drive supplied as a bare drive. It is built for enterprise and midline server environments that demand high-capacity storage with consistent reliability. The SAS interface supports dual-port operation for improved data-path redundancy. It fits standard large-form-factor drive bays in compatible HP ProLiant and storage systems.
Suits high-capacity server storage not
This drive suits administrators who need large, cost-effective capacity for bulk data, backups or near-line archives in 6 Gb/s SAS infrastructures. It is not for workloads that require low-latency random I/O or sustained throughput beyond what a 7.2K rpm mechanical drive can deliver. Builders needing hot-plug trays must source the appropriate carrier separately. Desktop PCs and consumer NAS units lacking a SAS controller cannot use this drive.
SAS 6Gb/s interface dictates controller
The single specification that decides fitment is the 6 Gb/s SAS interface. The host system must provide a compatible SAS HBA, RAID controller or backplane that supports 3.5-inch LFF drives. Without a SAS connection the drive will not function, regardless of available bays or power connectors.

Questions about this item
Will the SAS 6Gb/s interface on the 625031-B21 work with my older 3Gb/s SAS backplane?
Yes, the 6Gb/s SAS interface is backward compatible with 3Gb/s SAS controllers and backplanes, though the drive will run at the lower 3Gb/s link speed.
How can I verify the 7200 RPM spindle speed is active after installing the drive?
Check the drive's reported rotational speed in your RAID controller BIOS, operating system disk utility, or SMART data — it should show 7200 RPM.
The listing says bare drive; does the 625031-B21 include a 3.5" mounting tray or screws?
No, this is a bare drive only — you must supply your own 3.5" carrier tray and mounting screws for your server or enclosure.
