Test results: Atto Random Read
We use Atto to measure how well the drives can process random read- and write commands. We do so using both small block sizes (4 kB) and large block sizes (1 MB). The 4 kB speeds are mainly intended to provide insight in how well the drive performs when used as a disk for your OS and other programs. The 1 MB tests, on the other hand, offer insight in how well the drive performs when storing files of limited size. The results of the read tests can be found below.
Only the Toshiba drives end up ahead of the Seagate in Atto.
