Samsung Spinpoint M8 320GB 2.5" SATA drive

The Samsung Spinpoint M8 ST320LM001 is a 2.5 inch internal hard drive with a 320GB capacity and a 5400 RPM spindle. It connects through a SATA 3.0Gb/s interface and includes an 8MB cache. The drive is supplied as a bare unit in new condition.

Suits laptops needing a direct 2.5" SATA replacement

This drive fits notebooks that accept a 9.5mm high 2.5 inch SATA drive and need 320GB of storage. It does not serve buyers who want a solid-state drive or a larger capacity than 320GB. Builders whose chassis only accepts 7mm high drives cannot use this unit.

SATA 3.0Gb/s interface with 5400 RPM spindle

The single specification that decides fit is the SATA 3.0Gb/s interface combined with a 5400 RPM rotational speed. The drive delivers 12ms average seek time and 5.6ms average latency. Verify that the host system supports SATA 3.0Gb/s and has a 9.5mm drive bay before purchase.

Questions about this item

Will the 9.5 mm height fit my laptop's 2.5" drive bay?

The drive is 9.5 mm tall, 69.75 mm wide and 100.3 mm long, matching the standard 2.5" SATA form factor used in most notebooks.

Do I need any adapter or bracket to install the bare SATA drive?

No adapter is required; connect the drive directly to the laptop's SATA 3.0Gb/s port and secure it with the bay screws — the step often missed is forgetting to enable AHCI in BIOS for Native Command Queuing.

How can I monitor the drive's health over time?

The drive supports ATA S.M.A.R.T., so you can track reallocated sectors, seek errors and temperature with any standard S.M.A.R.T. utility.
