"Reliable" is somewhat meaningless...when one tries to apply it to components that are subject to problems at any point in time, for a variety of reasons.
It has a 3-year warranty, if that's what "reliable" means to you.
If you interpret "reliable" as "nothing will ever go wrong with it"...I don't think that interpretation will apply to very much in the process of living.
This is the way I approach SSDs: New technology, somewhat related to RAM. Chances are that an SSD produced by a known manufacturer of "quality RAM"...is very likely to work satisfactorily, barring any abuse by owner/user.
The rest is user preference. I bought a Corsair SSD for my first...so my second and third have been more recent models by Corsair. If I had bought an OCZ SSD first and not had problems with it...I'd now own 3 OCZ SSDs. I don't pay much attention to disparaging comments about quality by a given manufacturer...because that can happen to anyone, at any time...and as long as corrective action is taken, I see no reason to put the manufacturer on a cross forever.
In general...I consider SSDs "more reliable" than current/past IDE/PATA drives...but I think those are pretty reliable, as long as the user doesn't ignore signs that a problem may be developing. I don't expect them to be perfect and I'm satisfied with the level of performance they give me.
I will add...that between the PSU and the PATA hard drive...users will find the system components that are most likely to fail, IMO. There may be a correlation...in that those two components are probably asked to do so much that is crucial to the system.
