Seagate BarraCuda 500 GB

This is a 500GB 3.5" HDD on the SATA interface. Sequential throughput tops out at 550 MB/s reads and 520 MB/s writes, backed by 32MB of cache. At roughly $0.11 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.

Its $54.99 price tag places it squarely in mid-range territory. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total.
