Capacity and interface

This is a 1.5TB 3.5-inch desktop hard drive with a SATA 3.0Gb/s interface and 7200 RPM spindle speed. It uses second-generation perpendicular magnetic recording technology and includes a 32MB cache. The drive is supplied as a bare unit without retail packaging.

Suitable uses and limits

It suits buyers adding bulk storage to older desktops or replacing a failed drive in a system that only supports SATA 3.0Gb/s. It is not for builders who need a current manufacturer warranty, as the product is end-of-sale and carries only a one-year seller warranty. It is also not for users who require a drive with zero bad sectors, since up to 25 may be present.

Firmware revision requirement

The critical specification is the firmware revision: drives with part numbers ending in 138-300 or 138-366 must run revision SD17, SD15 or SD18 and can be upgraded to SD1A. Buyers should verify the revision on the label before installation to avoid known compatibility issues.

Questions about this item

How does the 1.5TB capacity hold up under continuous write workloads?

The drive uses second-generation perpendicular magnetic recording to reach 1.5TB with fewer moving parts, and the 32MB cache helps buffer sustained transfers over the SATA 3.0Gb/s link.

What temperature or noise level should I expect when the 7200 RPM spindle runs all day?

At 7200 RPM the drive produces typical desktop-class acoustic and thermal output; the SATA interface supports Native Command Queuing to reduce unnecessary head movement.

Does the SATA 3.0Gb/s connector work with my current motherboard and power supply?

Any motherboard with a standard SATA port and a power supply offering a 15-pin SATA power connector will support this 3.5-inch bare drive.
