Right part for a 2.5" SATA bay

This Toshiba MK1059GSM is a 1TB mechanical hard drive built for a standard 2.5-inch SATA bay in a laptop or compatible enclosure. It spins at 5400 RPM with an 8MB cache buffer and connects through a SATA 3.0Gb/s interface. The bare-drive unit arrives new and ready for installation.

Interface decides fit

The single specification that determines compatibility is the SATA 3.0Gb/s interface, also described as Serial ATA Revision 2.6. If the host system provides a SATA data and power connector for a 2.5-inch drive, this unit will communicate correctly; any other interface type will not work.

One terabyte of magnetic storage

The 1TB capacity handles operating-system files, applications and large media libraries in a single volume. Sequential throughput is limited by the 5400 RPM spindle speed and the 3.0Gb/s link, so sustained transfers run well below modern SSD speeds. Random access averages 12ms seek time plus 5.55ms latency, which is adequate for bulk storage but slow for heavy multi-tasking workloads.
