SSD have no moving parts, they will last longer. Dont listen to jet lol
SSD have a limited write cycle, granted it's high, but it's still limited.
Yet my ssd that I used less than 2 years died before any of my regular drives, some I had been using for 6+ years. It wasn't even a cheap OCZ...
There are instances where I'd use a SSD, long term storage isn't one of them.

from Lu's article:
I guess mine was just an old model, or a rarity, but the fact still remains that they have a limited write cycle.
I'd still go with a raid array, in fact I did. I have 3 3tb set up in raid 5, they're WD green due to price, and I don't really need speed on drives for what I do, but I guess it all depends on your needs.
I'm sure there's people who test the speeds and whatnot and write articles about it, so it may be best to read those before you invest, but the idea of using a ssd as write-cache for regular hard drives intrigues me.
