Is that supposed to be a joke? 3ware has certainly had their fair share of 
stability problems (drive time-outs, bbu-problems, inconsistent 
behaviour, ...) and monitoring wise they suck (imho). Do you like tw_cli? 
Enjoying the fact that "show diag" gives you a cyclic text buffer without 
references? etc.

...that said, it's not much worse than the competetion, storage simply 
sucks ;-(
