I wouldn't trust any hard drive, SSD or otherwise, with anything important. Throw a second drive into the machine and back up to it, so you don't have to reconfigure everything from the ground up if there's a failure.
In terms of SSDs, the newer ones are better than the older ones. In my experience (which is reasonably extensive - I own a small IT company, and use a fair number of SSD and spinning drives for desktops and servers), newer SSDs have been proving reliable enough to trust. Over the last year or so, they've gotten much better. When I've experienced a failure on older SSDs, they tended to not just die, but start to lag and return timeouts. I was still able to retrieve all of the data from them and move it to a new SSD.
Still - backups are the answer. Or RAID, if you're a fanatic (use RAID class drives, not desktop drives, though - desktop drives wander off for several seconds when they have problems, which will cause the whole machine to stop in it's tracks while it does it, and often cause a blue screen. RAID class drives don't waste time on problem data - they just mark the sector bad, report the error to the RAID controller, and move on. Something like the Western Digital RE4 is a good choice for RAID).
What I've done with the build I'm working on is put an accessible USB on the cabinet, then if I add a table or change something, I plug in an external USB hard drive and image the entire SSD to it so I have a complete copy of the entire install, Windows and all. That's as safe as safe gets *grin*. I could just as easily connect a network cable to the cabinet and image to a machine on the network, too. I could even automate the process to happen at 3am or something, too, if I wanted to go bananas - lots of desktop backup tools have that ability. Acronis comes to mind right off.
So, there's some ideas to protect your hard work. Setting up the perfect configuration is a fair amount of effort - it's worth backing it up.
