Seagate Constellation ES.3 1 TB

A 1000GB 3.5" HDD on the SATA interface. At roughly $0.06 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 128MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Expect to pay around $60.00, which lands it among mid-range options. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost.
