Hi Folks! Just wanted to know if my plan is a good one or if there are any stumbling blocks I haven't seen. I want to install Lion on my extern FW drive and if everything runs smoothly I am going to clone it to my internal SSD. I am go gin this way as my Laptop is my productive Tool and I cannot cope with any misfunctionality due to early adopter bugs. Hence, running Lion on the external disc gives me the possibility in case of any problems to switch back to SL. Regarding FileVault: I guess it's better to turn it on after having it on the SSD, right! Did I oversee any performance issues or something which are worth to install Lion directly on the SSD instead of doing a cloning from the external FW drive? Thanks for your advices! Cheers, S.
