Seagate ConstellationProduct Series:ES.3 3 TB

A 3000GB 3.5" HDD on the SATA interface. At roughly $0.03 per gigabyte it sits in the mid-range 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 $99.99 price tag places it squarely in mid-range territory. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current drive prices across retailers. Seagate backs the product through its standard warranty channels; check the listing for region-specific terms.
