I can't speak to this, except to point out that it is almost 18 months
old, which is quite a long time in kernel development space.
With the right incantation, one can call smartctl directly on a drive
connected to a 3ware controller, no matter what kind of array it is in.
(I believe you can even call it on a drive assigned as a hot spare.)

I've run an exclusively 3ware shop since I ditched my last aacraid
machines a few years back. But with all their issues, I am definitely
considering trying Areca on my next server that's not planned to be
immediately mission-critical. (I wouldn't switch back to Adaptec unless
I knew their interface tools, and especially their cli, had improved
dramatically; the aaccli/afacli interfaces were simply atrocious.)
