After hearing those "instant app lanches", I have been itching to upgrade the stock HDD on my 2.0 alum-MB to a SSD. I did some research, apparently most (if not all) of the SSD MLC drives currently in the market are made by Samsung - including the "Apple Brand" SSDs in the custom order MBs and MBPs. Unfortunately, according to the following review, these drives use a Jmicron controller that causes stuttering/pausing/lagging during the use of the drive, making their performance to be much lower than conventional HDD. I don't know if the Apple SSD is Jmicron-based (anyone ?). http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3403&p=6 Anyhow, the above review also looked at a new SSD drive made by Intel, which does not suffer this problem, and as a result, outperforms all other SSDs tested. Intel X25-m - that's the one I ordered It's not cheap though, $850 Canadian total after taxes, etc. I'll keep you posted, but it'll probably be a couple of weeks before I get it.
