I've seen Intel drives on Windows 7 be about as robust as any other digital equipment ever manufactured.
You get what you pay for, caveat emptor, read the product reviews, etc
I had a 120GB Intel SSD on Win7, and it's the only drive that's ever failed on me. I've never had an HDD failure.
I went to turn on my PC one day and it couldn't find the OS... Looked in the BIOS and my Intel drive was just plain missing. Completely dead without any warning, only 9 months after purchasing it!! The worst part was that I hadn't pushed to my remote Git repository for 2 weeks and put myself way behind schedule...
Intel's also had a massively wide-spread fuck-up with their firmware on their 120GB drives, like Draco is complaining about. If you have one, make sure you've updated to the latest firmware or you risk it being bricked! (a threat I've never faced with any other drive...)
General performance with an SSD is amazing, so I recommend them to everyone (I now have 2 - the replacement Intel and a 240GB SanDisk), but thanks to Intel I now also warn everyone to pair it with a HDD backup for when it dies.
