320 GB 2.5" SATA laptop drive

The Seagate Momentus Thin ST320LT007 is a 320 GB internal hard drive built for laptops and compact gaming devices. It spins at 7200 RPM and connects through a standard SATA 3.0 Gb/s interface. The drive is sold new and carries a 16 MB cache buffer.

7 mm or 9 mm height compatibility

This model fits any system that accepts a 2.5 inch SATA drive with a 7 mm or 9 mm z-height. The 3.0 Gb/s SATA link is the single specification that decides whether the drive will work in a given machine. Verify that the host supports SATA 3.0 Gb/s before purchasing.

Fits tight bays and frees a 3.5" slot

The 2.5 inch form factor lets the drive slide into thin ultrabook bays, small-form-factor desktops or external enclosures. Using this drive leaves a 3.5 inch bay free for additional storage or other components. No mounting adapter is required when the chassis already provides 2.5 inch screw holes.

Questions about this item

How does the 7200 RPM spindle speed affect everyday performance?

The 7200 RPM spindle speed allows the heads to reach data faster than slower-spinning drives, which shortens boot times and application launches in a laptop or gaming device

What does the SATA 3.0 Gb/s interface mean for real-world throughput?

The SATA 3.0 Gb/s link caps the maximum transfer rate at 3.0 gigabits per second, so sustained reads and writes cannot exceed that bandwidth even if the platters could deliver more

Will this 2.5-inch drive fit in a bay designed for 9 mm or 7 mm heights?

The drive is built to the 2.5-inch form factor and is specified to fit any laptop or gaming device that supports 9 mm or 7 mm hard-drive bays
