Seagate Constellation ES.3 4 TB

A 4000GB 3.5" HDD on the SATA interface. At roughly $0.04 per gigabyte it sits in the high-end 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.

Its $180.00 price tag places it squarely in high-end territory. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current drive prices across retailers.
