SSD vs. HDD Performance

[Brian Cluff]

I've never had one fail on me yet, but from what I read of other people 
that have had failures, it seems that the SSD will usually just 
completely fail when it does, giving you no way of recovering the data 
from the parts of the chips that weren't effected.... but who wouldn't 
have a backup right?  But like you said, that might have been first or 
second generation drives that were doing that.  In reality, even with 
the MTBF rating, we really shouldn't be seeing any of them failing yet.
