HPE 750 GB SATA hard drive

This HPE 432341-B21 provides 750 GB of storage on a 3.5-inch SATA 1.5Gb/s interface spinning at 7200 RPM. It is built for non mission-critical server applications and storage environments with workloads of 40% or less.

Tray-attached hot-swap design

The drive ships with a tray attached for hot-swap installation in compatible HPE ProLiant server bays. This allows replacement without powering down the chassis, reducing downtime for low-workload arrays.

1.5 Gb/s SATA interface limit

The SATA 1.5Gb/s interface caps sustained throughput well below modern 3 Gb/s or 6 Gb/s controllers. Buyers needing higher sequential bandwidth should select a drive with a faster SATA revision.

Questions about this item

How often will the 750GB SATA drive need replacement under typical workloads?

The drive is rated for workloads of 40% or less; running it within that duty cycle gives the longest service life before a swap is needed.

What limits sustained throughput on the 1.5Gb/s SATA interface?

The 1.5Gb/s SATA link caps maximum transfer rate, so that interface ceiling appears before the 7200 RPM platters can deliver more data.

How much heat and noise does the 3.5-inch 7200 RPM drive produce during all-day operation?

The 3.5-inch 7200 RPM mechanism generates typical enterprise-level heat and acoustic output for continuous use in a server chassis.
