Travelstar Z7K320 320GB laptop drive

The Hitachi Travelstar Z7K320 is a 320GB 2.5-inch internal hard drive spinning at 7200RPM with a 16MB cache. It uses a SATA 3.0Gb/s interface and is designated for laptop computers. The drive weighs 0.21lbs and measures 2.8in wide by 3.9in deep by 0.3in high. It arrives new in retail or OEM packaging.

SATA 3.0Gb/s throughput ceiling

The Serial ATA interface on this drive is rated at 300Mbps external transfer rate. That ceiling is set by the SATA I generation the drive implements. A 7200RPM spindle and 13ms seek time deliver mechanical performance within that bandwidth limit. The 16MB buffer helps smooth burst traffic but cannot push sustained throughput past the link speed.

Verify 2.5-inch bay and SATA power

Before ordering confirm your system has a free 2.5-inch internal bay and a SATA data plus power connection. The 0.3in height fits standard slim bays but some ultra-thin chassis require 7mm drives. Ensure the motherboard or controller supports SATA I speeds; newer ports are backward compatible but will not exceed the drive's 300Mbps rating.
