2 TB desktop hard drive

This 3.5 inch SATA drive provides 2 TB of storage for desktop PCs and external enclosures. It uses a SATA 6.0 Gb/s interface and a 64 MB cache. The spindle speed varies with IntelliPower technology. The unit is a bare drive without cables or mounting brackets.

Refurbished unit for bulk storage

This refurbished drive suits users adding affordable bulk capacity for backups, media libraries or secondary data volumes. Buyers who need the sustained write speeds of a 7200 RPM performance drive should look elsewhere. It is not intended as a primary OS drive where low latency matters.

SATA 6.0 Gb/s interface

The drive connects through a standard SATA 6.0 Gb/s port found on most desktop motherboards and RAID controllers. Compatibility depends on an available SATA data cable and a matching power connector from the power supply. Systems limited to the older SATA 3.0 Gb/s standard will still operate the drive at the lower link speed.

Questions about this item

Will this 3.5" SATA drive work with my older motherboard that only has SATA 3.0Gb/s ports?

Yes, the SATA 6.0Gb/s interface is backward compatible with SATA 3.0Gb/s ports, so the drive will operate at the slower speed on older hardware.

How can I verify the IntelliPower spindle speed and 64MB cache are active after installation?

Use a tool like CrystalDiskInfo or your BIOS to confirm the drive reports a 7200 RPM rotation rate and a 64MB buffer size.

The listing says "Bare Drive" — does it include a SATA data cable, power cable, or mounting screws?

No, a bare drive includes only the hard drive itself; you must supply your own SATA data cable, power connection from the PSU, and 3.5" mounting screws.
