Get the read and write speed from your harddisks, cd-rom 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 drive access modes, from easy to advanced: QuickAccess, FileAccess & BlockAccess.
SSD and HDD speed test benchmark


Compare and submit your test results on the Benchmark page.



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.



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.

You can adjust the used blocksize to access the disk. This will affect greatly the transfer speed.

In QuickAccess, you can press the ‘Ctrl’ key to skip the random access speed.

The Windows version has several command line options. See the ‘Options’ tab in Parkdale.

ParkdaleCmd.exe Command line options:

-d <D:\> Drive for testing
-s <1000> File size in MB
-b <1024> Block size in kB
-l <0> 1: Create log file, 0: don’t Create log file
