SSD reliable for primary work HDD?

I wanted to get another year or two out of my work laptop so I bumped the RAM to 8 GB and purchased a small (64 GB) SSD. In preparation for the install, I have been browsing the forums, reading up a bit.

I notice a fair amount of discussion on SSD concerning data loss and drive failure. I cant have that... I back up as much as the next guy (every several months), but I need it to be as reliable as a spinning HDD... Should I be nervous?
