Seagate Exos 7E8 512n 4 TB

This is a 4000GB 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 high-end tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $185.00 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. Warranty coverage follows Seagate's standard policy — confirm regional terms on the listing.
