Overview
A 640GB 3.5" HDD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 16MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts.
Warranty coverage follows Hitachi's standard policy — confirm regional terms on the listing. Every published spec is tabulated below, and compatibility against your current part list is checked automatically. Not sold on this particular drive?
