Hi, I am new to Mac's so I am wondering if I am doing something wrong here. I just bought a 17" Mac Book Pro (April 2011 model) and wanted to install a SSD drive. So I formatted using Disk Utility and then cloned my drive using carbon copy cloner. I then tested it by booting off of it on the usb port. It worked fine. It actually ran very fast off the USB. I then installed the SSD drive into my Mac and then when I booted up it took forever (several minutes) then once it was running it was so slow. I even tried another cloning program called super duper. Same result. I then tried to do a fresh install from my original drive attached to a usb. After downloading Lion from the server and running through the setup it failed. I am thinking the SATA connector on the motherboard is not compatible with the Kingston SSD drive. Its like the connection works but is very very slow. Does anyone have an idea what to try here. I have searched around but have not found anyone else having a similar problem. I know that the SSD drive works, also its only a couple of weeks old. I went to Kinstons site to check for a firmware update but there was not any. Thanks in advance.
