Hitachi Travelstar Z5K500 320 GB

A 320GB 2.5" HDD on the SATA interface. At roughly $0.12 per gigabyte it sits in the budget tier. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 8MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $38.99 price tag places it squarely in budget territory. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current drive prices across retailers.
