How many insertion/removal cycles for 800D hot swap drive trays

I've started to really use these trays. I insert and remove these trays so I can boot up my system between different OSs. I want to be absolutely sure that I keep my "production OS" plus my data, photos, etc., all safe from possible problems associated with downloading software for trials.



What I can't find is a spec or guideline on the maximum number of insertion/removal cycles for either the trays or the backplane in the 800D case.
