As mentioned in the title I have enough funds to get a high end SSD. I have a decision between two such drives: Intel x25-M 160Gb or Intel x25-E Extreme 64Gb I have no problems with the M version except that its MLC (multi-level cell) which wears 10 times faster than SLC drives. I really want to get the 64gb E version except I am wondering this: After I install OSX on it, how much space will I have to work with? If its over 50GB then I'm sold. I have no problem using external storage (because I have literally near-infinite supply of flash drives) . Anyone have experience with either of these drives or an intel ssd of any version? Thanks!
