You'll see a hell of a lot of it.
What it should look like is, unfortunately, not what it does look like when we had Areca issues If I only had issues with one controller, I'd scratch it as a faulty one.
The only time I have ever had issues with the array disappearing and/or showing multiple raid sets (all inaccessible) is when at one point the volume states became a *FAILED* state which would mean 3 disks failing on raid6 or 2 disks failing on raid5, etc...

Also with the newer firmware (not necesarily cards) the cards are much better about detecting this situation and automatically reviving the failed volume set. I actually couldn't get it to fault the array if I had the disks hooked back in as it kept reviving the failed array. I was purposely doing this as I was writing up a wiki article for areca raid recovery (if say the wrong disk was pulled) for the company I work for.

Also Areca is one of the easier raid controllers to recover the array by re-creating it with the no init/rescue option. I myself have recovered a raid5 array with no corruption when the wrong disk was pulled when it was degraded.

The thing is. I have used areca, 3ware, and LSI and I have seen far more arrays lost to quirks on 3ware/LSI than I have on areca (we are talking 100+ machines of each brand).

Biggest problem I have had with areca is the ARC-1222's as I mentioned.
