Hi everyone, Let me start by saying that YES I have researched this information and currently have 18 Macrumors threads that I'm looking through to answer these questions, but I wanted to ask them myself too. - I have a 2011 MBP and am thinking about upgrading the HDD with a Samsung 840 series SSD. Is this a good brand? Will it increase my performance? Is it worth it? - Will installing a third party SSD cause problems with OSX updates and upgrades? - How can I enable TRIM on this drive? - How do I get my system back on it? Create a ML Recover drive to install OSX and then use a Time Machine backup? Thank you for helping me. Yes, these questions my be answered by reading the aforementioned threads that I am working on, but I wanted some personal feedback since I do not have money to waste. Thank you so much. ---------- OH! And.. -How do I update the firmware and know when an update exists. -I need a 2.5 SATA connection does SATA II or SATA III matter or are they interchangeable?
