The bottom one's been a solved problem for many years with SSD's now. Just waiting for the other two to catch up. Not entirely sure of the wisdom of getting yet-another-controller with little testing and real-world use put in front of my data, but that's at least a problem that can be solved quite simply but just *not* relying on it.
Kind of a block to desktop use, though, as is the capacity in my opinion (others disagree, but I'd rather have a drive that wasn't quite so fast, had an older, more reliable controller - at least one where the bugs are known - and had twice the capacity advertised (1Tb is about the minimum now for drives intended for storage) than just about ANYTHING else in the world of IT equipment). Sure I can RAID or install multiple drives for networks and servers, but that's not where SSD's will actually have the most impact, or make the most difference to my life. Whereas a 1Tb SSD with the write speed and reliability of a 5-year-old SSD controller would be worth what they are asking for the 512Gb model.
