    Okay, so I have a 12" powerbook, and i like downloading lots of know.... anyway, I obviously don't want to put it all on the drive in my powerbook, because it's already dying, and I don't really want to push that.

    I built an external box out of an electronics project box, put a couple switches on it, and put some drives inside it. Put some IDE to USB 2 converters inside, a powersupply, and now I have a 700 gig external setup.

    Anywho. The problem is, I want to do things like leave my computer on all night, with my drives plugged in, and download straight to them. I have a usb hub installed inside the box, so it's all going into one usb port on the powerbook. What I want to know is, how intensive is this on the disk inside my powerbook? Does OS X write data do the disk, and then transfer it out, does it write it to the computer's bus, and then send it out straight through usb skipping the internal drive altogether? Or something else?

    theats a really cool idea, a raid external hdd kit :p, btw how much did it cost and how did you get the converters

    PS, i belive it goes to ram not the hdd, but that depends on your programs

    I'm usually using the FTP program Transmit. So it would go into my ram, and out of USB without interacting with my internal drive?

    (the project box is cheap as ****, you can get it from radio shack for a couple bucks. converters are maybe 15 bucks each, switches and wiring are a couple bucks, plus drives. pretty goddamn cheap)
