Western Digital WD Red Pro 8 TB

A 8000GB 3.5" HDD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 128MB of cache. At roughly $0.08 per gigabyte it sits in the premium tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $654.99 price tag places it squarely in premium territory. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current drive prices across retailers.
