SSDs are generally reliable (not withstanding slow speeds for older models), as long as you don't get the cutting edge ones.
Even then, that is why we should make use of the Time Machine feature.
The C300 is not being used (got a great deal, so bought it for the future), waiting for firmware update and refresh of MBP line. Other SSDs I have in use are 2 Intel G2 ones, 80GB in MP and 160GB in wife's UniMB and OCZ Vertex 120GB in Win7 system. Haven't had any issues with any of them, blazing speeds and love them.
