Hi everybody and thanks for reading. I'm about to get a 256GB SSD and 8GB RAM for my stock MBP (MacBook Pro 5,5, 2.53GHz Intel Core 2 Duo Processor, 4GB RAM, 250GB HD @5400RPM) and my two options are (from amazon.es): Kingston V200 - 151 euro (2-4 week delivery) Crucial M4 - 179 euro (on stock) Is one of them better than the other or works better with my mac model? Do they support TRIM and do I need it? Or should I just go for the cheapest one? I use my laptop for photo editing on Aperture, GarageBand, maybe some games (Diablo III and WoW, but very seldom), and the regular use (mail, safari, Skype, iTunes, etc). Thanks a lot! BTW, the RAM is also Kingston 2x4GB 1066MHz - 38 euro (on stock) Also, is there a way that I can enable PowerNap?
