750 GB 7200 RPM SATA drive

This 3.5 inch internal hard drive delivers 750 GB of storage on a SATA 1.5Gb/s interface. It spins at 7200 RPM and fits standard 3.5 inch bays with maximum dimensions of 146.05mm length, 101.6mm width and 26.11mm height. The HP 432341-B21 is supplied new and qualified for entry server and external storage environments.

Suits desktop storage upgrades

This drive suits users adding bulk capacity to a desktop or entry-level server that accepts a 3.5 inch SATA 1.5Gb/s device. It is not for systems that require a 6Gb/s or 3Gb/s SATA link, nor for 2.5 inch bays, M.2 slots or PCIe-based storage. Buyers needing higher areal density, lower power draw or hot-plug trays not included with this unit should consider other form factors.

SATA 1.5Gb/s interface speed

The single specification that decides fit is the 1.5Gb/s SATA interface. If the host controller or backplane only negotiates at this first-generation rate the drive will operate at its rated throughput; if the system expects a faster link the drive will still work but cannot saturate the bus. Verify the controller specification before purchase.

Questions about this item

Will the 101.6 mm width and 26.11 mm height of this 3.5" drive fit my server bay?

The drive measures 101.6 mm wide, 26.11 mm high and 146.05 mm long, matching the standard 3.5" form factor used in most server and desktop bays.

How do I install the drive using the supplied tray, and what step is often missed?

Slide the drive into the hot-swap tray, secure it with the four side screws, then insert the assembly into the bay until the latch clicks; the step often missed is fully engaging the latch to lock the SATA 1.5Gb/s connector.

When should I plan to replace this 750GB 7200 RPM drive in a RAID array?

Monitor SMART reallocated-sector counts and replace the drive once the count rises steadily or the array controller flags a predictive failure, typically after several years of continuous operation.
