Seagate Constellation ES 500 GB

This is a 500GB 3.5" HDD on the SATA interface. At roughly $0.18 per gigabyte it sits in the mid-range tier. Sequential throughput tops out at 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.

At $89.99 it sits in the mid-range drive bracket. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
