Seagate Constellation.2 250 GB

This is a 250GB 2.5" HDD on the SATA interface. At roughly $0.21 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 64MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $52.25 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 fold its price into your running build total. Warranty coverage follows Seagate's standard policy — confirm regional terms on the listing.
