Drive Speed Test
Speed testing flash memory drives and hard disks
Storage size is not the only important factor for disk drives. Data transfer speed is very important for efficient use of the drive.
When testing data transfer speed it is important to use a method that is actual testing the storage device and not just operating system cache or RAM buffers on the device. Only this way can the true sustained transfer speed be measured.
Sustained transfer speed can most easily be tested with H2testw application.
The drives here are tested with H2testw version 1.4, unless otherwise mentioned. H2testw is made by Heise, most known for the world best computer magazine C't.
With H2testw speed test is performed of the whole drive or with a slice of the drive that is at least 4 times the PC RAM size to avoid OS buffers hiding the actual drive read / write speed. The speed test is repeated 3 or more times, to assure that measured time is consistent.
