Hitachi Ultrastar 7K4000 3 TB

This is a 3000GB 3.5" HDD on the SATA interface. At roughly $0.06 per gigabyte it sits in the high-end tier. Sequential throughput reaches 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.

Its $175.00 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.
