Western Digital Purple Pro 24 TB

A 24000GB 3.5" HDD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 512MB of cache. At roughly $0.05 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 $1146.99 price tag places it squarely in premium territory. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost.
