1.5 TB SATA Hard Drive

This 3.5-inch desktop drive delivers 1.5 TB of storage on a SATA interface with a 7200 RPM spindle and 32 MB cache. It is built for everyday desktop workloads such as operating system installs, application storage and general file archives. The hot-swap capability allows drive changes without powering down compatible enclosures or backplanes.

Suits desktop upgrades and hot-swap bays

Ideal for users replacing a failed mechanical drive or adding bulk capacity to a standard desktop chassis that accepts 3.5-inch SATA drives. Not suitable for laptops or small-form-factor systems that only support 2.5-inch drives, nor for builders who require an interface other than SATA.

7200 RPM spindle speed

The 7200 RPM rotation rate is the single specification that determines whether this drive meets the performance needs of a typical desktop workload. Buyers who need faster sequential throughput or lower latency should consider drives with higher spindle speeds or solid-state alternatives.

Questions about this item

Does the ST31500341AS require a separate SATA power and data cable to operate?

Yes, the 3.5in SATA drive needs both a SATA data cable and a SATA power connector from the host system.

Will the 1.5TB 7200.11 drive work alongside an older 3Gbps SATA controller?

The SATA interface is backward compatible, so the drive will operate at the controller's 3Gbps limit.

How can I verify the ST31500341AS is running at 7200 RPM after installation?

Check the reported rotation speed in BIOS or with a SMART monitoring tool; it should show 7200 RPM.
