Samsung Spinpoint M7E 320 GB

This is a 320GB 2.5" HDD on the SATA interface. At roughly $0.15 per gigabyte it sits in the budget tier. 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.

Expect to pay around $49.19, which lands it among budget options. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total.
