Seagate Momentus 7200.4 250 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 16MB of cache. At roughly $0.16 per gigabyte it sits in the budget tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $39.99 price tag places it squarely in budget territory. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current drive prices across retailers.
