I was wondering should I install an internal SSD in my 27' iMac Spring 2011, or purchase a Lacie little big disk external SSD and boot Lion from thunderbolt? The cost of doing each option is about the same price, because I can, but won't install the SSD myself. Which option is faster? Will I get the same speeds? Sorry for all the questions. googled this all night, and could not find anyone that has done this yet. Thanks in advance.
