Seagate BarraCuda 750 GB

This is a 750GB 3.5" HDD on the SATA interface. At roughly $0.15 per gigabyte it sits in the high-end tier. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 32MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Expect to pay around $112.50, which lands it among high-end options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
