HPE 1TB 3.5" SATA drive

The HPE 861686-B21 is a 1 TB internal hard drive with a 3.5 inch form factor and a 7200 RPM spindle speed. It connects through a SATA 6.0Gb/s interface and is supplied as a bare drive. The unit is rated for server environments such as the HPE Apollo 4200 Gen9.

Ideal for bulk storage in compatible servers

This drive suits administrators adding high-capacity 7.2K storage to supported HPE server bays. It is not for systems that require 2.5 inch form factors or drives with different interface standards. Buyers needing solid-state performance or a smaller physical size should consider other options.

SATA 6.0Gb/s interface decides compatibility

The single specification that determines fit is the SATA 6.0Gb/s interface combined with the 3.5 inch LFF form factor. Verify that the target chassis accepts 3.5 inch SATA drives before purchase. The drive carries a one-year limited warranty from the manufacturer.

Questions about this item

Does my server need a 3.5" drive bay and a SATA 6.0Gb/s port to install this 1TB hard drive?

Yes, the drive fits a standard 3.5-inch bay and connects through a SATA 6.0Gb/s interface, so the host must provide both.

Will this 7200 RPM SATA drive work in an older system that only supports SATA 3.0Gb/s?

The SATA 6.0Gb/s interface is backward compatible and will negotiate down to 3.0Gb/s on older controllers.

How can I verify the 861686-B21 is running at its rated 7200 RPM after installation?

Check the spindle speed reported in the server BIOS or use a SMART monitoring tool that displays the current RPM value.
