Thin 7 mm laptop drive

The Seagate Momentus Thin ST320LT012 is a 320 GB internal hard drive built for laptops that require a 7 mm z-height. It spins at 5400 RPM with a 16 MB cache and connects via a SATA 3.0 Gb/s interface. The bare drive measures 70.10 mm wide by 100.55 mm long.

Suits slim chassis upgrades

This drive fits ultra-thin notebooks and 2.5 inch bays that accept a 7 mm profile; it is also compatible with standard 9.5 mm bays. Buyers needing more capacity than 320 GB or faster access times than a 5400 RPM mechanical drive provides should consider other options.

SATA 3.0 Gb/s interface

The drive uses a SATA 3.0 Gb/s connection, the single specification that determines whether it will work in a given laptop..verify the host system supports this interface before purchase.

商品問答

How do I install the ST320LT012 in a laptop bay designed for a 9.5 mm drive, and what step is often missed?

The 7.0 mm height drive fits the wider bay, but you must add the supplied spacer or bracket so the SATA connector seats firmly and the drive does not shift.

What maintenance or replacement will the ST320LT012 need over its service life?

No scheduled maintenance is required; the drive is sealed. Plan to replace the unit once SMART attributes report reallocated sectors or the 320 GB capacity no longer meets your storage needs.

What limit appears first when the ST320LT012 is used continuously at 5400 RPM?

Sustained throughput is capped by the SATA 3.0 Gb/s interface and the 16 MB cache, so long sequential transfers will hit the bus ceiling before the platters reach their maximum speed.
