  • 7200RPM spindle speed delivers responsive performance
  • 256MB cache accelerates read and write operations
  • Hot-swap support allows drive replacement without downtime

HPE 10TB SAS Hard Drive for ProLiant Servers

This 3.5-inch LFF drive delivers 10TB capacity over a 12Gb/s SAS interface at 7200 RPM with 256MB cache. It is built for HP Gen8 Gen9 Gen10 ProLiant servers and compatible storage arrays requiring midline storage density.

Hot-plug carrier limits use to supported bays

The drive ships in a genuine HP SmartDrive carrier enabling hot-swap insertion. It fits only servers and arrays that accept this specific carrier format; it will not work in standard desktop bays or enclosures lacking SAS backplane support.

Enterprise midline design balances heat and power

Midline firmware optimises the 7.2K spindle for sustained throughput while managing thermal output in multi-drive chassis. The SAS dual-port architecture maintains data-path redundancy during normal operation without increasing acoustic profile beyond typical enterprise levels.

  • SAS 12G interface enables fast data transfers

Questions about this item

What does the 10TB capacity mean once the drive is installed in a server?

The drive provides 10TB of raw storage for data volumes, backups or archives in a ProLiant Gen8, Gen9 or Gen10 chassis.

How does the SAS 12Gb/s interface limit real-world throughput?

The SAS 12Gb/s link caps sustained transfer at the drive's 7200 RPM mechanical speed, so sequential reads top out around the disk's native rate rather than the bus ceiling.

What physical space and carrier does the 3.5-inch LFF drive need to mount?

It fits a standard 3.5-inch LFF bay and ships in an HPE SmartDrive hot-plug carrier that slides directly into Gen8, Gen9 or Gen10 ProLiant servers.
