320 GB 7200 RPM laptop drive

This 2.5 inch SATA hard drive provides 320 GB of storage and spins at 7200 RPM with a 16 MB cache. It is built for users who need a new mechanical drive for a laptop or compact desktop bay. The 3 Gb/s interface matches older SATA controllers. The bare-drive package contains only the drive itself.

Fits 2.5 inch SATA bays

The drive slides into any 2.5 inch internal bay with a standard SATA data and power connection. No caddy or adapter is required when the chassis already accepts 2.5 inch drives. Its 3 Gb/s link works with SATA I and SATA II host controllers. The lightweight 1.0 pound design keeps system weight low.

Steady 7200 RPM operation

The spindle maintains 7200 RPM during sustained read and write workloads rather than throttling to a lower speed. The 16 MB buffer absorbs burst traffic to reduce mechanical seeks. Mechanical latency remains consistent across long copy or backup sessions. The drive is rated for typical laptop duty cycles.
