Okay, we finally have a D1000 and controller card connected to the SunHELP
server.  Yay!

I've got some filesystems and meta database slices on 5 and 6 (a 9gig and
a 36gig).  

My question is - i've got the four 18G drives left.  Whats the best 
software RAID level that I can use for a good balance of performance
and reliability?  I first thought RAID-5, but then have read some 
newsgroup posts that say it *sucks* with big drives/partitions...

Thoughts?  Prior experience?  (DiskSuite 4.2.1 / Solaris 8)
