320GB 2.5" SATA Notebook Drive
The Toshiba MK3261GSYN is a 320GB internal hard drive built for 2.5-inch laptop bays. It connects through a SATA 3.0Gb/s interface and spins at 7200 RPM with a 16MB cache. The drive measures 9.5mm in height, 69.75mm in width and 100.3mm in length.
Suits older laptops needing a 9.5mm drive.
This drive fits standard 9.5mm drive bays found in many older notebooks and some external enclosures. Buyers whose systems require a 7mm or thinner drive cannot use this model. It is also unsuitable for anyone needing a solid-state drive or a larger capacity than 320GB.
9.5mm height decides fit
The 9.5mm maximum height is the critical dimension that determines whether this drive will seat correctly in a specific laptop or enclosure. Verify the bay clearance before ordering, as many modern slim devices only accept 7mm drives.

Questions about this item
Will the 9.5 mm height fit my laptop's 2.5 inch bay?
The drive is 9.5 mm tall, 69.75 mm wide and 100.3 mm long, matching the standard 2.5 inch internal form factor used in most laptops.
Does the SATA 3.0Gb/s connector need any adapter or bracket to install?
It plugs directly into a standard SATA data and power socket; the only common mistake is forgetting to secure the drive with the laptop's mounting screws after connection.
How often should I check the 16 MB cache or 7200 RPM motor for wear?
No scheduled cache or motor service is required; run SMART diagnostics periodically and replace the drive if reallocated sectors or seek errors appear.
