Server storage drive

The HPE 418371-B21 is a 72 GB internal hard drive built for 2.5-inch server bays. It spins at 15000 RPM and connects through a 3Gb/s SAS interface. The unit is supplied new and supports hot-swap installation.

Suited for capacity-bound arrays

This drive fits administrators who need low-latency spindle storage in existing SAS backplanes. It does not suit buyers who want more storage per slot, solid-state speed, or a larger form factor for desktop enclosures.

Deciding specification

The 3Gb/s SAS interface determines whether the drive will communicate with your controller. Verify that the host system accepts this exact interface standard before purchase.
