I don't trust SSD for audio/video editing where you're re-writing something a thousand times. I had some data destroyed on one I used. I just ordered a WD HDD for my latest computer.
I've read a lot about the failure rates and while SSDs fail less often, when they do fail, they fail completely. HDDs will gradually accumulate bad spots and maybe even "die" on you but they're usually recoverable. SSDs just go lights out without warning and this has been documented at length by corporations with massive data storage.
SSD prices fall a few % every month while their capacity and reliability grows. I'm going to hold out until the technology cools down then buy one. SSD prices have fallen approx 50% on a dollar/gb ratio the past year and probably will continue to do so.
Of course the best of both worlds may be a very small high quality SSD for a reasonable price with the essentials of your computer on it for speed, then some behemoth 2 tb HDD to store recordings, images, etc.
