Basically, I have a 5 disk RAID-5 array in an Addonics external enclosure.

I can't speak to your underlying problem, but if you add an internal (or
external) bitmap to your array, it speeds up rebuild time considerably.
At create time, you can use the " --bitmap=internal " option. I know
you can also add a bitmap to an existing array, but I don't remember the
magic incantation at the moment (you can probably find it by searching
the list archives - the topic has come up before). Or google "write
intent bitmap."
