Seagate Constellation ES.3 2 TB

This is a 2000GB 3.5" HDD on the SATA interface. At roughly $0.04 per gigabyte it sits in the mid-range tier. Sequential throughput reaches 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 $70.99 price tag places it squarely in mid-range territory. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total. Warranty coverage follows Seagate's standard policy — confirm regional terms on the listing. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build.
