Write Performance For this benchmark HD Tune Pro was used. To run the write benchmark on a drive, you must first remove all partitions from that drive and then and only then will it allow you to run this test. Unlike some other benchmarking utilities the HD Tune Pro writes across the full area of the drive, thus it easily shows any weakness a drive may have.
When it comes to sequential write speed this drive does lag behind its dual platter brother (the 640 Black) but once again if you slice off the first chunk of this drive via a separate partition, your numbers would certainly be improved. As it stands it’s still no slouch when it comes to write speeds and not that long ago it would have given the best of the best a run for its money.
