Samsung Spinpoint M7 320 GB

This is a 320GB 2.5" HDD on the SATA interface. Sequential throughput tops out at 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. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts.

Support and warranty service run through Samsung, 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.
