Western Digital Purple 8 TB

This is a 8000GB 3.5" HDD on the SATA interface. At roughly $0.06 per gigabyte it sits in the premium tier. Sequential throughput tops out at 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.
