Seagate IronWolf NAS 3 TB

A 3000GB 3.5" HDD on the SATA interface. 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. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.

Support and warranty service run through Seagate, with terms that vary by region. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build. The category page surfaces comparable models near the same price, which makes shortlisting against this drive straightforward.
