Overview
A 640GB 2.5" HDD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 8MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work. Use the PlanMyPC system builder to verify it works alongside your other components.
Support and warranty service run through Seagate, with terms that vary by region. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked. The category page surfaces comparable models near the same price, which makes shortlisting against this drive straightforward.
