Seagate storage, ranked by cost per terabyte
One of the two giants of the hard-drive world, and a regular fixture at the top of our value rankings. Compare every Seagate drive we track, sorted by real $/TB.
Seagate runs one of the broadest storage lineups on the market, and it leans hard into the spinning disk — which is exactly why it shows up so often near the top of our cost-per-terabyte rankings. The consumer end covers BarraCuda desktop drives, IronWolf and IronWolf Pro for NAS arrays, and SkyHawk for surveillance, while plug-and-play Expansion and Backup Plus units fill the external shelf. A handful of FireCuda models cover the NVMe SSD side.
Where Seagate really earns its place on a value site is high-capacity bulk storage. Its Exos enterprise drives — built for 24/7 datacenter duty — frequently land among the cheapest terabytes anywhere, especially through recertified and used channels that flood the enterprise drive market. For NAS builders and self-hosters chasing the lowest $/TB, a recertified Exos is often the drive to beat. The catalog below is filtered to Seagate and sorted cheapest-per-terabyte first, with the current best-value pick highlighted automatically.
