Western Digital RE4 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 64MB of cache. At roughly $0.08 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 $40.42 price tag places it squarely in budget territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
