Seagate Exos 7E10 4Kn 8 TB

This is a 8000GB 3.5" HDD on the SATA interface. Sequential throughput tops out at 550 MB/s reads and 520 MB/s writes, backed by 256MB of cache. At roughly $0.05 per gigabyte it sits in the premium tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $394.51 price tag places it squarely in premium territory. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost. Seagate backs the product through its standard warranty channels; check the listing for region-specific terms.
