Normally, yes, the computer can see the SMART status even in a RAID.
I've actually seen this a few times when a drive in a RAID started to fail.
My original recommendation stands;
If you want your stuff to last as long as possible,
turn it off and leave it off for as long as possible

It sounds like you've still missed a bit. The
MTBF of 136
years doesn't mean that your drive might last 136 years on
average, nor does it mean that if you buy 136 drives you
should expect one failure per year on average.
There's a longer discussion on Wikipedia:
http://en.wikipedia.org/wiki/MTBF
Do you have any disagreements or other interpretation of what's there?

UBCD has a range of disk diagnostic tools, modern Linux variants
have smarttools, you can track down any number of disk monitoring
tools for Windows.
Lately I've been wondering about just how well SMART is monitored.
Can the computer still read it if the drives are in a RAID?
