As we expected, Seagate's Desktop HDD.15 ST4000DM000 isn’t as fast as the Barracuda 7200.14. The difference isn’t really that large, though, and an average 132.2 MB/s sequential read speed and 131.5 MB/s sequential write speed is enough to put the new drive in second place for both benchmarks. This also means the 4 TB Desktop HDD beats several 7200 RPM competitors, like Western Digital's Black WD4001FAEX and the Hitachi Deskstar 7K4000.
The Desktop HDD.15 ST4000DM000 can't quite hit the 180 MB/s transfer rate that Seagate promises in our h2benchw benchmark. Its 167 MB/s are still very respectable, though.
Of course, because we're using the same SATA 6Gb/s interface as the one used on the Barracuda drives, we end up with similar performance across the wire (even though this is primarily a measure of the drive's cache).
