I just got a MBP, its a 15 with the 2.4ghz i7 and 4 gigs of ram. I was very surprised to find out that it is not very fast. Loading web sites can slow it down, and opening an app while one or two others are open will actually freeze it for a several seconds. Ive been reading about people getting speed increases after installing an SSD drive so Ive decided that Ill buy one and also increase the ram to 8 gigs. I plan to buy the Crucial M4. It comes with a data transfer kit and seems easy to do; plug in the SSD, use the transfer software to copy the os and apps, and then switch the drives. I was hoping that someone who has already done this could confirm that it is really that simple of a process. Ive read through the forum and tried to learn as much as I can, but I still dont understand advanced things like TRIM or updating firmware by burning ISO disks. That is past my skill level and I only want to proceed if this is a simple and painless process. I am also going to buy the Crucial 8gb ram kit. On Crucials web site you can search for your computer in order to find which of their products are compatible with your system. When I do this there are two different 8gb ram kits offered. They are both the same price and have identical specifications accept that one is 1.5 volts, and the other is 1.35 volts. Does anyone know what this difference is and which one is correct for my MBP? Any advice would be greatly appreciated. Thanks for the help. JFC.
