Supermicro HDD-T4000-ST4000NM00 4 TB

This is a 4000GB 3.5" HDD on the SATA interface. At roughly $0.05 per gigabyte it sits in the high-end tier. Sequential throughput reaches 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.

At $185.00 it sits in the high-end drive bracket. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current drive prices across retailers.
