I do not understand and will ever understand ppl who buy SSD upgrade from Apple. Even though it's reasonably priced (well, the 128GB version is) you don't really know what's inside - and since MacOS X doesn't support TRIM, garbage collection is crucial in maintaining speed and realiability of those drives...
Moreover, there's next gen of SF controllers around the corner (to be released in next month or so) which will be as fast in the slowest scenario as the current models are in the fastest scenario!!! And it will come in prices almost at the same level as the current gen...Not to mention next-gen Intel drives, that are gonna be released soon.
The only qestion remains is had Apple implemented 6Gbps SATA on the board, becouse if not, those new drives are just too fast for 3Gbps bus.
