Hello, Are you concerned about the shorter lifespan of MLC drives versus the SLC drives? I think I would lean toward longevity over the absolute fastest write performance, but that's obviously a personal preference. I see that OCZ offers an SLC drive with the super capacitor technology, but it's a lot more expensive.
