Data Recovery guy here...

SSDs are fast - but you better back them up. When an SSD fails its usually complete and without warning.

Spinning drives will often give you some warning signs, clicking, slowing down, bad sector errors etc.

Spinning disks can be rebuilt with new heads or platter swapped into a new body.

With SSDs you cant just remove the NAND chips and recover the data either. SSDs use dynamic wear leveling to shuffle pages of blocks around - in other words - block 0 is not at block 0 -it could be anywhere... and if the internal map is lost - good luck.

The data in the NAND chips is also encrypted... they do this to ensure that erased sectors are actually erased. Because of the wear-leveling routine spies could possibly recover data from unused sectors - the encryption makes this impossible.

And for extra fun - intel likes to epoxy the chips to the board - just to be sure they don't fall off....

I compare them to a hover-car, with wheels you can get a flat and still make it off the freeway... but with the hover-car your just a sitting duck...
