I have a Data scrubbing running once a month.
Defrag is not critical so I didn't schedule it and I performed it only once since I bought DS920+ few months ago.
I know that they're completely different but to understand more
1. Should I do it monthly or when I feel the disks are slow?
2. I know defrag can be risky if power fail but apart that?
3. Is it required to run data scrubbing after defrag? or the defrag itself "refresh" the 1 and 0 on the disk?
My guess is that some blocks are going to be skipped if they're not fragmented
4. Is it less stressing than data scrubbing? (if performed once a month)
Yes I do know Data scrubbing and Defrag are different, but I was googling and the decided to ask you guys hopefully someone can clarify.
I read the links below and some Reddit:
