Seagate Momentus 5400.6 160 GB

This is a 160GB 2.5" HDD on the SATA interface. At roughly $0.79 per gigabyte it sits in the high-end tier. 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.

Expect to pay around $126.00, which lands it among high-end options. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and fold its price into your running build total.
