I have been spending a fair bit of time looking at external harddrives recently as it would be a good idea to back my computer up somewhere. Throughout the process I have read a lot but am still not sure of a few things and have not really been able to find good answers. For reference, I have a late 2010 13" mbp. A few questions I have had: Is there any point in getting a firewire 800 vs firewire 400 enabled device? Unless I am connecting to a SSD external it seems that any optical external drive is going to have significantly slower speeds than even firewire 400. Is there a good place to get firewire drives? Is there a noticeable enough difference between usb 2.0 and firewire? Enough to justify trying to get a firewire external? Should I get a harddrive and external enclosure? Is this a worthwhile idea? It seems I can get a firewire external enclosure for ~30$ on Newegg, this would then let me put whatever internal drive I wanted in the enclosure right? Thanks in advance guys and gals.
