Overview
This is a 18000GB 3.5" HDD on the SATA interface. At roughly $0.04 per gigabyte it sits in the premium tier. 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.
Its $715.00 price tag places it squarely in premium territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
