How these two compare
Sequential throughput
Both quote 180 MB/s read — Seagate SkyHawk HDD 4TB at 180 MB/s write, Western Digital WD Blue 3.5-inch HDD 4TB at 180 MB/s — so throughput does not separate them on the number vendors print. Sequential rate on a spinning disk comes down to platter speed and density, and reading and writing land close together.
Cache
Seagate SkyHawk HDD 4TB ships with 256 MB of cache built in, Western Digital WD Blue 3.5-inch 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 SkyHawk HDD 4TB is warranted for 3 years, Western Digital WD Blue 3.5-inch HDD 4TB for 2. 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.
