Western Digital HTS723232A7A364 Travelstar 320GB HDD

The HGST Travelstar Z7K320, sold under the Western Digital brand, is a 2.5-inch internal hard drive built for notebook PCs, compact desktops, and portable external enclosures. Spinning at 7200 RPM, it delivers noticeably faster read and write speeds than the 5400 RPM drives commonly found in budget laptops, with a maximum media transfer rate of 996 Mbits/s and an interface ceiling of 300 MB/s over its SATA 3Gb/s connection. The 16MB data buffer helps smooth out sequential and random access operations for everyday computing tasks.

Where this drive stands out is in its power and portability profile. Drawing just 0.8 watts at active idle and weighing only 102 grams, it adds minimal strain to laptop batteries and keeps overall system weight down. Enhanced shock protection adds a layer of durability for users who travel frequently. At 320GB, the capacity is best suited as a boot drive, a secondary storage solution, or a replacement for a failing drive in an older system rather than as primary mass storage for large media libraries.
