Coding horror (Jeff Atwood) says this about ssd drives.

"Solid state hard drives are so freaking amazing performance wise, and the experience you will have with them is so transformative, that I don't even care if they fail every 12 months on average! "

The difference in an SSD failure and and hard drive failure is this.  When a hard drive starts failing you can recover most of the data. With a SSD it is a sudden and total failure.
