[QUOTE="MacInWin, post: 1804617, member: 396914"] Patrick, I think what he's asking is for data on the internal controller in the MBA, and for the on-drive controllers on those drives. The former may be available somewhere, but the latter may well be proprietary and vendor controlled, so not available. I do know that those specific on-drive controllers work at the lowest level and normally cannot be replaced without having to do a low-level reformat of the drive (even lower level than what the operating system does). The head movements and track definitions are controlled in those controllers, for example. And I have no idea what the control circuits on an SSD would do--maybe control the constant maintenance on the drive as data flows in and out? I have no idea why he's asking for that, either, as it isn't going to do much good, unless he plans to build his own SSD from memory chips and a controller chip (plus all the support chips and components). And that would most likely cost a lot more than the $400 he wants to avoid. So, I'm totally lost as to what the goal is any more. [/QUOTE]
