Also will dump a screen capture here just in case it is of help - off topic relates to PerfectDisk. I ran a lot of testing on PerfectDisk but we never deployed it here based on initial size settings and the assumption of new hardware to set files correctly when transferring. Physical fragmentation can often be avoided with predictions in file growth needs. If you set up a collector to check available space once a week you can get a general idea of growth - logged to a database that you can take the query into excel and give that projection to Net people or Management to determine what storage needs you will have in the future, before it becomes a problem.
Anyway, screen capture attached. Sorry for all the black marks. Not really need for security but once a pictures gets on the internet... meh. Could not do much with the SMART capabilities when testing against a testing server setup with 2 raid 0's and one raid with a previously failed drive (on purpose).
The screen capture shows the online capability that was tested, though I still recommend your own tests since I was on a physical machine with DAS and not VM with SAN.
