Seagate Constellation ES 1 TB

A 1000GB 3.5" HDD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 64MB of cache. At roughly $0.09 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.

Expect to pay around $89.00, 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.
