Overview
A 18000GB 3.5" HDD on the SATA interface. At roughly $0.05 per gigabyte it sits in the premium tier. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 512MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.
