320 GB 2.5" SATA laptop drive

This 320 GB Toshiba MK3256GSY is a 2.5 inch internal hard drive built for laptops and other mobile systems. It spins at 7200 RPM with a 16 MB cache and connects through a SATA 3.0 Gb/s interface. The bare-drive unit is supplied new and suits storage upgrades or replacements.

Suits older notebooks and light storage needs

It fits users refreshing an older notebook that still uses a 2.5 inch SATA bay and who need modest capacity for documents and applications. Buyers who want more storage space or the speed of solid-state storage should look at other options.

320 GB capacity with 7200 RPM headroom

The 320 GB platter provides room for an operating system, everyday programs and a personal file library. Average seek time is 11 ms and average write time is 12 ms, so the drive handles typical office and web workloads comfortably. Large media libraries or modern game installations will exceed the available space.

Questions about this item

Does my laptop need a 2.5" SATA 3.0Gb/s bay to install this MK3256GSY?

Yes, the drive uses a 2.5" form factor and a SATA 3.0Gb/s interface, so the host must provide a matching 2.5" SATA bay and connector.

Will the 11 ms average seek time feel slower than an older 7200 RPM drive I keep as a secondary?

The 11 ms average seek time and 12 ms average write time are typical for this 7200 RPM model; performance will be comparable to other 7200 RPM drives of similar specification.

How can I confirm the 320GB capacity and 7200 RPM speed are recognised after fitting the bare drive?

Check the BIOS or operating-system disk utility; it should report 320GB capacity, 7200 RPM rotation speed and a SATA 3.0Gb/s link.
