HP 4 TB SATA III Desktop Drive

The HP 693687-B21 is a 4 TB, 7200 RPM hard disk drive with a SATA III interface in a 3.5 inch form factor. It is built for desktop or server storage expansion and arrives in new condition. The LFF design matches standard large-form-factor drive bays used in compatible HP systems.

Suited for capacity-focused builds.

This drive suits users who need high-capacity bulk storage for backups, archives or media libraries on a SATA III connection. It is not for workloads that demand the low latency or high throughput of solid-state storage. Systems limited to slower SATA revisions will not reach the drive’s full interface speed. Buyers needing a 2.5 inch form factor or a different interface should consider other options.

SATA III interface determines host compatibility

The single specification that decides fit is the SATA III interface; the host must provide a compatible SATA port and a 3.5 inch drive bay with appropriate power and data cables. The 7200 RPM spindle speed and 4 TB capacity follow from this interface choice. Verify that your controller and backplane support SATA III before purchase.

Questions about this item

How loud and hot does the 7200RPM 4TB SATA drive run during continuous operation?

The 7200RPM spindle and SATA III interface produce typical mechanical-drive warmth and audible seek noise; ensure your chassis has front-to-rear airflow over the 3.5" bay.

What host connector and bay size must my system provide for this 693687-B21 drive?

A standard SATA data port, a SATA power connector, and a 3.5" LFF drive bay are required; the drive is designed for HP DL160, DL360 and DL380 G8 servers.

Will this 6G SATA III HDD work in an older 3G SATA backplane without speed loss?

The SATA III interface negotiates down to 3G automatically, so the drive functions normally on legacy controllers, albeit at the lower link rate.
