Defrag - Find out how long?

BaJohn, I support your intent, as metrics are something I consider important, but I am unlikley to be adding my data anytime soon to your scrub post. If my rig could potentially take 200 hours to complete a scrub job, I'm just going to leave well enough alone :?

What you don't know is if the percentage complete is actually accurate and your scrub would have completed a lot sooner.

Unfortunately I have only done the one scrub myself and my next is scheduled for a few weeks time, and other users either do not do scrubbing, or do not want to impart the information.
The other scrub data supplied seems to be much quicker than mine, but this MAY be due to different OS, hardware, RAID configuration etc.
Until more information can be gathered it is difficult to know what to expect, BUT I would think 200 hours (if that was what it turned out to be) would be abnormal.
Incidentally, suggestions by 'the experts' indicate that scrubbing probably should be done every 3 months or so.
If you are not going to do it, then there presumably will be consequences of making that choice.
