Hitachi Deskstar 5K3000 3 TB

This is a 3000GB 3.5" HDD on the SATA interface. Sequential throughput tops out at 550 MB/s reads and 520 MB/s writes, backed by 32MB of cache. At roughly $0.1 per gigabyte it sits in the premium tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Expect to pay around $299.00, which lands it among premium options. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost. Warranty coverage follows Hitachi's standard policy — confirm regional terms on the listing.
