Price
Seagate IronWolf HDD 4TB is £184.00 (£46.00 per TB); Toshiba N300 HDD 4TB is £245.37 (£61.34 per TB).
Spindle speed
Seagate IronWolf HDD 4TB turns at 5400 RPM, Toshiba N300 HDD 4TB at 7200 RPM. Higher RPM shortens the wait for data under the head; lower RPM tends to mean less power draw and a quieter drive.
Cache
Seagate IronWolf HDD 4TB ships with 256 MB of cache built in, Toshiba N300 HDD 4TB with 256 MB. The buffer lets the drive take in a burst of writes before the platter catches up and keeps recently read data close — useful under mixed, stop-start load, less so for a single large copy.
Warranty
Seagate IronWolf HDD 4TB is warranted for 3 years, Toshiba N300 HDD 4TB for 3. The cover is the maker's own commitment; a longer one usually signals a drive built for heavier duty, though it is the mechanism, not the paperwork, that has to last.
