NAS Disk Test - Find out how long?
Being new to ReadyNAS there were various things I wanted to know.
One of these was the NAS Disk Test, either via boot options, or scheduled volume settings on recent OS.
The tests are a SMART Extended disk test and run time depends on disk model and size, not volume of data on disk.
Thus repeat tests with the same kit should take a similar time, testing all disks in parallel.
Now having understood more about it, the obvious question is how long does it take.
I have now run 2 scheduled disk tests and supply my data (first line) along with that from others.
So I suggest that those who are interested post their information here, similar to the format below.
Disks ......... Type ..................... Disk Test time ...... Comment
6 of 4 TB .... WD40EFRX (Red) ....... 3 Hrs 15 Mins ....... (avg) 3 hrs 17 mins and 3 hrs 13 mins. Very consistent.
6 of 4 TB .... WD40EFRX (Red) ...... 16 Hrs 21 Mins ....... Same system as above? (See http://www.readynas.com/forum/viewtopic.php?f=11&t=81427)
2 of 3 TB .... WD30EFRX (Red) ....... 3 Hrs 33 Mins ....... (avg) 4 hrs 5 mins and 3 hrs 1 min.
3 of 3 TB .... WD30EFRX (Red) ....... 7 Hrs 38 Mins ....... (avg) 7 hrs 50 mins and 7 hrs 26 min.
2 of 6 TB .... WD60EFRX (Red) ....... 12 Hrs ............... Aprox.
I hope this will be a useful post providing new users a good quality expectation of how long their system might take.
Obviously more data for different disk types would be very useful.
PLEASE ADD YOUR DATA TO THIS POST with any comments, and I will update the above.

Any theory as to why it is so long compared to the other entries in this thread?- There are some bugs here.
With spindown enabled, the log said the disk test on my WD60EFRX completed quickly. But what actually happened is that the disk was spun down at that "completion" time. When I ran smartctl the next morning, the test was actually still running.
I disabled spindown and ran the test the next night. This time the actual completion time was logged (about 12 hours).
Netgear says there are some fixes in the works. - Confirming a bug similar to StephenB. I scheduled an overnight disk test, only to find the system non-responsive in the morning. Forced restart and it spent the next 12 hours resynchronizing (X-Raid).
The only thing wrong in my case is that the self-test was detected as finished when it wasn't. The test actually ran to completion.Labdoc wrote: Confirming a bug similar to StephenB.

My system never went non-responsive, so your bug sounds different.
