tray Posted February 7, 2007 Share Posted February 7, 2007 Hey all, I would like to seek your advice on the above. Scenario 1: I daisy-chain 4 1-Drive FireWire400 enclosures. I can only use FireWire400 as that is the only option available on my 20’ iMac. USB2 as I have learnt is a poorer alternative. As I foresee that I would be transferring files often between these external drives, I wish that file transfer speeds between these enclosures would be fast. I have read that FireWire communicates via node-to-node. Therefore, in a daisy-chain of the 4 drives. If I were to transfer a 1GB file from one external drive to the other, it would enjoy the theoretical 400mbps? Scenario 2: I purchase a single 4-Drive enclosure that has 4 bays in which I slot my HDD in.The drives could be SATA/PATA but it does not matter since the bottleneck is the FW400 speed right? This enclosure is connected to my Mac via a single FW400 cable. Suppose I transfer a 1GB file in the aforementioned scenario, between drive to drive. Does the node-to-node principle still apply? That is, is the file is transferred directly from drive to drive? Or, is it transferred first to the internal hard disk drive on the iMac? If so, would that mean that the file transfer speed would be slower since it involves simultaneously reading/writing from the iMac which would theoretically halve the transfer speed to 240mbps? I could be uttering nonsense; if so, I do seek your clarification.Thanks! Link to comment Share on other sites More sharing options...
