Western Digital Caviar Green 3 TB

This is a 3000GB 3.5" HDD on the SATA interface. At roughly $0.04 per gigabyte it sits in the high-end tier. Sequential throughput tops out at 550 MB/s reads and 520 MB/s writes, backed by 64MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Expect to pay around $129.00, which lands it among high-end options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
