Western Digital VelociRaptor 600 GB

A 600GB 2.5" HDD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 32MB of cache. At roughly $0.42 per gigabyte it sits in the high-end tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Expect to pay around $249.95, which lands it among high-end options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
