Hitachi Deskstar NAS 10 TB

This is a 10000GB 3.5" HDD on the SATA interface. Sequential throughput tops out at 550 MB/s reads and 520 MB/s writes, backed by 256MB of cache. At roughly $0.02 per gigabyte it sits in the high-end tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Expect to pay around $189.95, which lands it among high-end options. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing.
