Hi there, thanks for reading this post, I am looking for some help . I bought a 1.66 gen 2 Mac Mini (late 2006, OS10.5.6 fully updated) to use as a home/file/ftp/itunes/etc server. It is connected with cat 6 to my gigabit switch. On the other side of that switch is my macbook 1.83 gen 1 (early 2006, OS10.5.6 fully updated), which will be a (gigabit) client waiting for all those GB's to be sent back and forth to my Mini (the main function is a fileserver, so swapping GB's should be fast!!!) Now I am at the stage of buying new storage for my server (was thinking about 1 or 2 TB). My current USB drives give me some 20MB/s of tranfer speed (from Mini to Macbook) which is acceptable, but frankly, just too slow. Here is my question; what would be the fastest solution ? I could buy a cheap USB solution, connect it to the Mini. I could also connect a more expensive FW400 drive. And I have the option to plug-in a NAS drive in the gigabit switch directly. Is there any way to say anything about prospect speed performance ?? Or is it the hard drive (i.e. cache memmory, rotation speed, etc) itself (or my macbooks 5400K internal hard drive) which will be limiting the speed (and thus rendering my question irrelevant)?? Any insight would be helpfull. I know the maximum speed rates (480mbps, 400 mbps and 1000mbps) for the aforementioned connection standards, but I have no idea what would be the limiting factors (i.e. will it ever be remotely reach these speeds). I know eSata might be possible as well with a Mac Mini hack, but for now I am not too happy with modding it (only considering this if this would be a real performance gain). Anyway, help !!!
