Capacity and interface

This HP Midline drive provides 500GB of storage on a 3.5-inch form factor with a SATA 3.0Gb/s interface. It spins at 7200 RPM and has an average seek time of 8.5ms. The unit is supplied in retail packaging and carries a one-year limited warranty. It is intended for desktop and entry-server installations that use a standard SATA connection.

Who this suits and who should look elsewhere

The drive suits administrators adding economical bulk storage to servers or external arrays with workloads of 40% or less. It also fits desktop users who need a 3.5-inch SATA disk for backups or archival tasks. Buyers who require higher throughput for mission-critical workloads or who need a 2.5-inch form factor for small enclosures should consider other options.

Hot-swap tray compatibility

This model includes a hot-swap tray, allowing insertion and removal without powering down the host system. The tray fits standard 3.5-inch hot-swap bays found in compatible HP server chassis. Verify that your enclosure accepts this tray type before purchase.

Questions about this item

How does 7200 RPM affect real-world file transfers on this HP Midline 458928-B21?

The 7200 RPM spindle combined with 8.5 ms average seek time delivers responsive access for backups and archival workloads typical of Midline drives.

What does the SATA 3.0Gb/s interface limit on this 500GB drive?

The SATA 3.0Gb/s link caps maximum burst transfer at 3.0 Gb/s, so sustained throughput will not exceed that ceiling.

Will the 3.5-inch form factor fit my server hot-swap bay?

Yes, the 3.5-inch form factor matches standard hot-swap trays used in HP Midline server chassis.
