A couple of crucial M4 128GB working great ~ 1 year, and 6 months.
One OCZ Vertex 3 128GB working great ~1.5 year.
One OCZ Vertex 4 256GB working super great ~6 month.
I used to recommend M4, but now, I can recommend Vertex 4 (only from the experience for 6 months).
By the way, if you had a startup issue with SSDs, try disabling write cache from the manage menu. When I push restart button, SSDs sometime failt to load boot sectors. I think the write cache is the culprit, because I disable it, and since then I don't have such problems.
