Are you looking to benchmark your Mac's internal hard disk? How about running a speed test on your new external hard drive or flash drive? Don't worry, there is a piece of free Mac software out there that is able to do just that without requiring you to spend a penny.

The software is called the Blackmagic Disk Speed Test and it can be found within the Mac App Store. This useful utility is developed by the people over at Blackmagic Design with the intention of determining whether or not your current disk will perform well enough to work with high quality video. Personally, I use it for all my hard drive and flash drive reviews as I've found it to be an effective resource for speed testing and benchmarking purposes.

Here are some sample tests I've done using the Blackmagic software:

15″ Retina Macbook Pro (2012) 256 SSD – Disk Speed Test

27″ iMac (2012) 1TB HD at 7200 RPM – Disk Speed Tes

Feel free to leave your own disk speed results in the comments below! The real question is can anyone beat my Retina's 256 SSD speeds?
