Seagate Pipeline HD 250 GB

This is a 250GB 3.5" HDD on the SATA interface. At roughly $0.3 per gigabyte it sits in the mid-range 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 $74.25, which lands it among mid-range options. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total.
