Data Scrubbing - Find out how long?

System ..... OS ....... RAID .... Disks ......... Total ........ Scrubbing time
RN516 ...... 6.2.4 .... 5 ....... 6 of 6 TB .... 27.17 TiB ... 1 day, 5 hours, 5 minutes and 44 seconds
Ran scrub for the first time since NAS installed (around November 2013).
System OS Raid Disc Usable Space Used Data SnapShot Free
RN104 6.4.1 5 (X-Raid) 3 * 1TB WD10EFRX-68JCSNO 1.81TB 828.95GB 330.97GB 692.38GB
Total time 66 Hours 47 Minutes
Oddly the first 26.67% took 51 hours 38 minutes with the remaining 73.33% taking only 15 hours 9 minutes.
Question – When using raid 5 with data striped across 3 spindles is it worth running the scrub utility?
Will now see how long the balance option takes or should it be defrag before balance? Beats me.
