Seagate Enterprise Capacity 4 TB

A 4000GB 3.5" HDD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 128MB of cache. At roughly $0.04 per gigabyte it sits in the high-end tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.
