The stress level can be set between 1GB and 5GB in 1GB increments. 5GB is the default
setting and will provide the most accurate results.

About Disk Speed Test
About Disk Speed Test displays which version of the Disk Speed Test software you
are running.
Start
Click the 'start' button to commence the test. Disk Speed Test will write and then read
a temporary file to the selected target drive. Disk Speed Test will continue writing and
reading until you stop the test by clicking the 'start' button again.
Will it Work?
The 'will it work?' panel shows common video formats and displays a check mark or
cross to indicate if disk performance is adequate. Be sure to do several test cycles to
reveal any video formats for which the disk performance might be marginal. If a video
format exhibits a check mark switching between a cross, it indicates that the disk
storage cannot reliably support the video format.
How Fast? (FPS)
The 'how fast? (FPS)' results panel shows the frame rates your drive can achieve and
should be read in conjunction with the 'will it work?' panel. If the 'will it work?' panel
shows a green check mark for 2K DCI 25p in 10-bit YUV 4:2:2, but the 'how fast? (FPS)'
panel shows that a maximum of 25fps will be supported, the disk storage performance
is too marginal to be reliable.
