Capacity and interface

This is a 2 TB 3.5-inch desktop hard drive with a SATA 3.0 Gb/s interface, 7200 RPM spindle speed and 32 MB cache. It is built for enterprise storage workloads and ships as a bare drive. Features include Data Lifeguard and Shock Guard for data integrity.

Who it suits

It suits system integrators and IT managers who need high-capacity nearline storage in standard 3.5-inch bays and value the 7200 RPM sustained transfer rate. It is not for buyers who need a SATA 6 Gb/s interface, smaller 2.5-inch form factors, or solid-state latency for boot drives.

Deciding specification

The SATA 3.0 Gb/s interface is the single specification that decides compatibility; the drive will not negotiate a faster link speed on a 6 Gb/s controller. Verify that your backplane or motherboard supports this generation before purchase.

What does the 7200 RPM speed mean for actual performance in my desktop?

The 7200 RPM spindle delivers enterprise-class sustained transfer rates and low latency for nearline workloads.

The drive uses a SATA 3.0 Gb/s interface — what does that limit in practice?

The SATA 3.0 Gb/s link sets the maximum burst transfer ceiling for the drive.
