I just lost 2 of my 3 weeks of travel photos because my Intel SSD (X-25 80GB) completely failed. It just up and died, no warning, no possibility of recovery. I even took it to the Apple Genius Bar and none of their tools could get it to mount. I travel with a LaCie rugged external drive and had backed up just 1/3 of the way into my trip. Next time I back up nightly.
I am going back to spinning drives in my MacBook Pro. When they fail, there's usually a way to get at least some of the data back.
