Overview
A 4000GB 3.5" HDD on the SATA interface. At roughly $0.16 per gigabyte it sits in the premium tier. Sequential throughput tops out at 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.
Expect to pay around $654.99, which lands it among premium options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
