HP 450GB 10000 RPM SAS Enterprise Drive

This HP 652572-B21 is a 450GB 2.5 inch internal hard drive spinning at 10000 RPM with a SAS 6Gb/s interface. It is built for enterprise servers and storage arrays that require high transaction rates and consistent throughput. The hot-pluggable design allows drive replacement without system downtime in compatible bays.

Suits servers needing 10000 RPM SAS storage

This drive suits administrators upgrading or repairing HP ProLiant and similar servers that specify 2.5 inch SAS drives at 10000 RPM. Buyers whose chassis only accept 3.5 inch form factors cannot install this unit. Systems requiring capacities above 450GB should consider higher-density alternatives. Laptops and consumer desktops lacking a SAS controller will not support this drive.

SAS 6Gb/s interface decides compatibility

The single specification that decides fitment is the SAS 6Gb/s interface combined with the 2.5 inch 15.7mm height form factor. The host backplane or controller must provide a SAS 6Gb/s connection and a drive bay that accepts the 15.7mm z-height. Without both, the drive will not function or physically install.

Questions about this item

What practical throughput does the SAS 6Gb/s interface cap at for this drive?

The SAS 6Gb/s link tops out at 6 Gbit/s, so sustained reads and writes cannot exceed that bandwidth regardless of the 10000 RPM spindle speed.

What physical clearance does the 2.5 inch 15.7 mm high drive need in a server bay?

It requires a 2.5 inch SFF slot that accepts a 15.7 mm z-height, 75.7 mm width and 118.7 mm depth, matching the standard hot-plug carrier dimensions.

How is the HP SmartDrive carrier installed and which step is often missed?

Slide the carrier into the hot-plug bay until the latch clicks, then press the release button to lock it; skipping the latch engagement leaves the drive unseated and not recognised.
