According to the blurb, they still have disk cache, albeit much smaller, 32 MB, though I'm not sure how that comes into play if they're using the SLC NAND as a write cache. That's typically what the 32 MB cache is for. At any rate, it might be a good a way to speed up disk I/O, though you obviously don't have the same properties as a full-blown SSD.
