Hitachi 7K500 160 GB

A 160GB 2.5" HDD on the SATA interface. At roughly $0.5 per gigabyte it sits in the mid-range tier. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 16MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $79.83 price tag places it squarely in mid-range territory. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost.
