Hitachi Deskstar 7K4000 4 TB

A 4000GB 3.5" HDD on the SATA interface. At roughly $0.05 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.
