Western Digital VelociRaptor 300 GB

This is a 300GB 3.5" HDD on the SATA interface. At roughly $0.83 per gigabyte it sits in the high-end 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 $249.95 price tag places it squarely in high-end territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
