BarraCuda 1.5TB Desktop Hard Drive
The Seagate BarraCuda ST1500DM003 is a 1.5TB 3.5-inch internal hard drive spinning at 7200 RPM with a 64MB cache. It connects via a SATA 6.0Gb/s interface and uses Seagate OptiCache technology to improve performance by up to 45 percent. The drive is supplied as a bare unit without cables or mounting brackets.
Suits storage upgrades and secondary data volumes
This drive suits desktop owners adding bulk storage for documents, media or backups where solid-state speed is not required. It is not for buyers who need an operating-system drive with low latency or for systems that only accept 2.5-inch or M.2 form factors. The bare-drive packaging also means it lacks retail accessories.
Standard 3.5-inch SATA installation
Installation follows the usual 3.5-inch SATA procedure: secure the drive in a bay, attach a SATA data cable and a SATA power connector, then initialise it in the operating system. The drive was erased to DoD 5220.22 M standard and tested good, though up to 25 bad sectors may be present. SmartAlign technology handles alignment without jumper changes.

Questions about this item
Will the 3.5-inch 1.5TB SATA 6.0Gb/s drive fit and power on in my desktop case?
The 3.5-inch form factor mounts in standard desktop bays and the SATA 6.0Gb/s interface connects to any SATA data and power cable already present in a typical PC.
Can the 7200 RPM 64MB cache drive serve as a secondary store alongside an older SATA 3.0Gb/s mechanical disk?
Yes, the SATA 6.0Gb/s interface is backward compatible so the drive will operate at the slower link speed when paired with an older controller.
How do I verify the 1.5TB capacity and 4.16ms latency are healthy after installation?
Initialise the drive in Disk Management, confirm the full 1.5TB appears, then run a SMART self-test to check for reallocated sectors and latency performance.
