250 GB 7 mm laptop drive

The Seagate Momentus Thin ST250LT012Product is a 250 GB internal hard drive built for slim laptops. It uses a 7 mm z-height in the standard 2.5-inch form factor. The drive spins at 5400 rpm with a 16 MB buffer and connects through a SATA 3Gb/s interface.

Suits thin-and-light notebooks.

Buyers upgrading an ultraportable or replacing a failed slim drive will find the 7 mm profile and SATA compatibility straightforward. Users who need sustained transfer rates for video editing or large database work should look at faster-spinning or solid-state alternatives.

7 mm height decides fit in modern slim bays

The 7 mm thickness matches current thin-laptop drive bays. Older caddies designed for thicker drives may require an adapter, which is not included. Verify the bay specification before purchase.

What comes in the box and what must I buy separately?
