[QUOTE="chappers, post: 882869, member: 77473"] I have a unibody MBP with the Expresscard 34 slot. I am currently running a LaCie Quadra drive via an eSata card. The problem is using the eSata card the speed of back up has dropped dramatically, as I gather the efi update earlier this year caused problems with cards using the Silicone Image chip. ( Yes mine uses that chip. ) It's getting to the point when I need to add an additional drive. The question is do I go for another Quadra or similar drive, and hope that Snow Leopard will fix the problem or opt for a USB or Firewire 800 drive. Doing some speed tests on a largish batch of files I found that the eSata transfer took 2.05 mins. The Firewire 800 took 2.10 minutes and the USB took 2.2 minutes. What surprised me was the relative slowness of the Firewire 800 transfer. Could this be down to the LaCie Quadra interface eSata, Firewire 800, Firewire 400, and USB. Suggestions and comments greatly apreciated [/QUOTE]
