Checking Disk Speed
Blackmagic Disk Speed Test is a fun application that measures the read and write performance of storage
media, then displays the results using video formats.
If you have ever wondered whether your hard drive is suitable for recording ("write") or playback (“read”)
of a particular video format, you can use Disk Speed Test to find out. Test the performance of your media
drives with a single click of the Start button! Disk Speed Test will even show you how many streams of
video your storage is capable of handling.
Disk Speed Test is included free in the Blackmagic Camera Software Utility supplied with your Blackmagic
Cinema Camera and Production Camera 4K. The Blackmagic Camera Software Utility can also be
downloaded from our website free of charge.
Use Disk Speed Test to find out the performance of your
media drives.
