Refurbished 320 GB laptop drive
This Toshiba MK3261GSYN is a 2.5 inch internal hard drive with a 320 GB capacity. It spins at 7200 RPM and includes a 16 MB cache on a SATA 3.0Gb/s interface. The drive is supplied as a bare unit in refurbished condition.
Suits older SATA notebooks.
It fits laptops that accept a 9.5 mm high 2.5 inch SATA drive and works as a direct replacement for a failed original disk. Buyers who want more storage space or the lower latency of solid-state storage should look at something else.
7200 RPM spindle speed
The 7200 RPM rotation rate is the single specification that determines whether this drive meets the performance requirement for a given system. It delivers higher sequential throughput than slower-spindle alternatives in the same form factor.

Questions about this item
How do I install the MK3261GSYN into a 2.5" SATA bay, and which step often goes wrong?
Slide the 9.5mm-high drive into the bay, align the SATA data and power connectors, then secure it with the four side screws. The step people miss is forgetting to screw the drive down, which lets vibration shorten its life.
What maintenance or replacement will this 7200 RPM drive need later?
Mechanical drives do not need scheduled maintenance, but the bearings and motor wear over time. Plan to replace the unit once SMART reallocated-sector counts rise or seek noise becomes noticeable.
What limit appears first during sustained writes on the SATA 3.0Gb/s interface?
The SATA 3.0Gb/s link caps sustained transfer speed, so the interface saturates before the 16MB cache or 7200 RPM platters reach their own limits.
