2.5" 7200 RPM SATA 3.0Gb/s drive

The Toshiba MK1656GSY is a new 2.5-inch internal hard drive spinning at 7200 RPM with a 16MB cache and a SATA 3.0Gb/s interface. It measures 9.5mm in height, 69.75mm in width and 100.3mm in length. Average seek time is 11ms and average write time is 12ms.

Suits compact systems needing 7200 RPM speed

This drive fits notebook PCs, Energy Star desktops, tiny all-in-one systems and graphics workstations that require a 2.5-inch form factor and 7200 RPM performance. It operates between 5°C and 55°C with idle and seek acoustics of 23 dBA. Builders needing a 3.5-inch form factor, a SATA 6.0Gb/s interface or solid-state speed should look elsewhere.

SATA 3.0Gb/s interface decides fit

The drive connects via a SATA 3.0Gb/s interface, so the host must provide a matching SATA port and 2.5-inch bay with 9.5mm clearance. If the system only accepts SATA 6.0Gb/s for full throughput or requires a different physical connector, this unit will not meet the requirement.
