Disk Speed Test is an easy to use tool to quickly measure and certify your disk performance for working with high quality video! Simply click the start button and Disk Speed Test will write test your disk using large blocks of data, and then display the result. Disk Speed Test will continue to test writes and reads from your disk so you can evaluate both performance and readability over time.

What's New in Version 2.2

New graphics for Retina display support

Some SSD's use hidden compression when writing data to make their benchmarked speeds appear faster. Disk Speed Test will now measure the true speed of these SSD's so you know if they are suitable for high quality uncompressed video capture.

doesnt read, read speeds properly

i installed a 64gb crucial m4 in my 2.3ghz 2011 mac mini. and tried to run this. it ran normaly for the write speeds, but when it came to read, it gave me an automatic 15! and skipped back to write. tried deleting, redownliding, restarting nothing helps. PLZ FIX!

Can't scroll

The UI doesn't fit in my 13" laptop and there is no way to scroll down. Please fix this.


A good app to know the read and write speeds of your hard disk especially good for comparisons if you are thinking to install an SSD on your mac and remove the already installed HDD.
