1 TB 7200 RPM SATA hard drive

This HP 657750-S21 is a 3.5-inch internal hard drive with a 1 TB capacity and a 7200 RPM spindle speed. It connects through a SATA 6.0Gb/s interface and is supplied as a bare drive. The unit carries RoHS green compliance certification.

Server storage workloads

The drive is designed for server and mass-storage environments where high-capacity rotational storage is required. It suits administrators who need reliable bulk storage for archives, backups or secondary data sets. Builders who require solid-state responsiveness or a smaller 2.5-inch form factor should look elsewhere.

SATA 6.0Gb/s interface

The SATA 6.0Gb/s interface determines whether this drive can be installed in a given system. Verify that the host controller or backplane supports the SATA/600 standard before purchase.

Questions about this item

Does the 657750-S21 ship with cables, brackets or a tray?

The drive is supplied as a bare unit only; SATA data and power cables plus any 3.5" mounting hardware must be sourced separately.

Why choose the 1 TB 7200 RPM version over other capacities in this lineup?

It balances 1 TB capacity with 7200 RPM spindle speed for server workloads that need both space and responsive throughput.

What does the 6.0 Gb/s SATA rating mean once the drive is installed in a server?

The SATA/600 interface supports up to 6.0 Gb/s burst transfers; actual sustained rates depend on the 7200 RPM platters and the host controller.
