I have mixed feelings about SSDs in the enterprise.

At home, I run four consumer-grade SSDs in RAID-0, and I have yet to have  
a problem.

At work, we tried to set up a bunch of enterprise-grade SSDs for a SAN,  
and drives were failing just about as fast as we could swap them out. It  
wasn't the controller (tested fine on rotary disks), it was definitely the  
drives. They just seemed to randomly crap themselves when presented with  
any kind of throughput that bumped up against what they claimed they were  
rated for. We spent a lot of man-hours and real money tying down the  
problem, and ended up RMA-ing the entire shipment, and falling back to  
15Krpm SCSI.

Also at work, I run a single enterprise-grade SSD in my workstation, and  
so far, it has failed to fail.

Make of that what you will.
