Capacity and interface

The Seagate ST500DM002 is a 500GB desktop hard drive with a SATA 6.0Gb/s interface and 16MB cache. It fits standard 3.5 inch drive bays and suits builders adding bulk storage to PCs, home servers or entry-level direct-attached storage arrays.

Bare drive build and mounting

Supplied as a bare drive without retail packaging, the unit measures 146.99mm long, 101.60mm wide and 19.99mm high. The SATA data and power connectors follow the standard layout, so installation proceeds like any other 3.5 inch mechanical drive in compatible chassis or drive cages.

Erased condition and sector allowance

Each drive has been erased to DoD 5220.22 M compliance and tested functional, though it arrives unformatted and unpartitioned. Up to 25 bad sectors may be present and cosmetic markings can vary, so buyers needing pristine media or zero-defect assurance should look elsewhere.

Questions about this item

What does the SATA 6.0Gb/s interface cap in real use?

The SATA 6.0Gb/s link tops out at 6Gb/s; sustained throughput will be lower and depends on the drive’s internal mechanics and the host controller.

What clearance does the 3.5 inch form factor with 19.99mm height and 146.99mm length need?

A standard 3.5 inch bay with at least 19.99mm vertical clearance, 101.60mm width and 146.99mm depth will accommodate the drive.

How is the bare drive installed and which step is often missed?

Mount the drive in a 3.5 inch bay, attach SATA data and power cables, then initialise and format the 500GB volume in the operating system before use.
