Hi, I just bought a Intel 320 SSD 160gb in retail box for my late 2008 Macbook. I'm just wondering whats the best way for me to switch to the new ssd given my situation. I have Mac OS 10.5.5 install dvds, and upgraded to snow leopard(discs) then lion(download). I have an external harddrive that I use for time machine. Also are there any other things I need to be aware of with this new ssd? Like trim for example. Should I follow these instructions? http://www.mactrast.com/2011/07/how-to-enable-trim-support-for-all-ssds-in-os-x-lion/ Thanks!!
