Western Digital Red Plus 3 TB (WD40EFZX)

This is a 3000GB 3.5" HDD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 256MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work. Use the PlanMyPC system builder to verify it works alongside your other components.
