Western Digital RE2 500 GB

A 500GB 3.5" HDD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 16MB of cache. At roughly $0.1 per gigabyte it sits in the budget tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $48.51 price tag places it squarely in budget territory. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost.
