Get the read and write speed from your harddisks, cdrom devices and network servers in Kilobyte, Megabyte or even Gigabyte per Second. Compare your drive with others on the Benchmark page.
There are three different modes, from easy to advanded.
Single click speed test using the filesystem. This test shows you the sequential read & write access speed and the random access speed using 4KB blocks and 32 concurrent threads. You can select multiple drives, these will be tested one after the other and the results will be written to a log file. So you can easily compare multiple drives.
You can compare and submit your test results on the Benchmark page
The test data is read from / written into a normal file using the filesystem.
The test data is read from / written onto the disk sectors directly without using the filesystem. A graph shows the transfer rate over time.
