Western Digital AV-25 250 GB

This is a 250GB 2.5" HDD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 32MB of cache. At roughly $0.32 per gigabyte it sits in the mid-range tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Expect to pay around $80.00, which lands it among mid-range options. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total.
