hi I have a 24" high-specced iMac and a MBP. I normally transfer files between these macs using AFP using an airport extreme with gigabit support and gigabit cables on both macs. The speed maxes at 45MB/s and is normally in the range 20-40MB/s I bought my friend a 24" iMac and i was transferring a sum of 30GB of toast images. I went to wash my face and came back to see the transfer almost finished. initially i thought i selected around 10GB to transfer, but i was right, it was transferring the 30GB and it is almost finished. when i looked to the istat menus stats. The speed is around 75MB/s and the maximium was 80MB/s. Wow. These are fabulous speeds. is it due to SATA300 interface on the internal HDD in the iMacs and the sata150 in the MBP internal HDD? or it is just these iMacs are crazy machines ..?... Thanks.
