Hi Emilliano,
I can confirm the 3.5's work well in my Mac Pros. They simply slot into the drive bays. No more scsi adapters! I have 2 64GB's setup as a raid in each machine and get 9-10 layers of Pal SD in photo jpeg. I have not had time to play with AIC but Richard tells me I can get even more performce with this codec.
