Drive purpose

The HPE 693721-001 is a 4 TB 3.5 inch internal hard drive spinning at 7200 RPM with a SAS 6Gb/s interface. It is built for HP ProLiant DL320e Gen8 v2 server environments that require high-capacity, enterprise-class storage.

Build integration

The drive uses a standard 3.5 inch form factor and connects through a SAS 6Gb/s port, requiring a compatible backplane or controller in the host system. Its bare-drive packaging means mounting hardware and cables must be supplied by the chassis or enclosure.

Sustained operation

A 7200 RPM spindle speed supports continuous read and write workloads typical of server duty cycles. The SAS interface maintains consistent throughput during extended operations rather than only during short bursts.

Questions about this item

Will the 6Gb/s SAS interface become the bottleneck during sustained 7200 RPM operation?

The drive uses a 6Gb/s SAS link, so sustained throughput is capped at that interface rate even though the platters spin at 7200 RPM.

How much heat and noise does the 3.5" 7200 RPM mechanism produce when running continuously in a server?

As a 3.5" 7200 RPM SAS drive it generates typical enterprise-level heat and audible seek noise during all-day operation.

Which server backplane or controller must I already have to install this 6Gb/s SAS drive?

You need a compatible SAS backplane or HBA that supports 6Gb/s SAS; the drive is qualified for the HP ProLiant DL320e Gen8 v2 server.
