Ehh, what model? For the most part, they aren't worth it.
If you want a reliable budget SSD, look at the OCZ Vertex 4.
I disagree almost completely. The Sandisk Ultra is a very solid low-budget ssd, and the Extreme is *fast* (toggle nand, second-gen sandforce), and just as reliable. Sandisk is the only SSD manufacturer that makes it's own memory, and the only company I can think of that's been making enterprise-level SSD's longer than Intel.
