I've got a 2.5 SATA HD to use with my mac, but I need to get an enclosure. I have an E-Mac, so I know it has USB 2.0 and Firewire 400. It's running Tiger, but I've heard the USB 2.0 on the E-Mac isn't all that fast. Which would give me better speeds? A USB enclosure or a Firewire enclosure? And does the E-Mac provide enough power to run the Firewire enclosure via firewire only? EDIT: Ta - anyone else recommend fireware as well? On a related note, I'm looking for a way to keep using my external monitor as my only display. So far I have my E-Mac set up with Screen Spanning Doctor so my main desktop is on the monitor, with the E-Mac's display as a second display. But this gives me two issues. 1) If I move the mouse the right of the screen, it can go off the edge. This might seem like a minor irritation but I'd like a way to disable this if possible. 2) The E-mac screen is still on. I've cranked the resolution and contrast right down but presumably the E-Mac's CRT still has a finite life and I see no reason to have the screen running if I'm not using it. 3) There must be some kind of performance hit, even if I'm not using the second desktop. I tried using ScreenChangerX and some other program to set the default res of the E-Mac to 1600x900, so the external monitor would work but the E-Mac screen wouldn't, but no luck so far. I also tried using boot.plist but I'm on Tiger so I don't think the system looks for or uses that. Finally, is there any danger in sitting the E-Mac on the carpet under the desk? I can't see any X-Box 360 style ventilation that could be blocked at the bottom.
