I'm surprised that there's over a 9-hour time difference when transferring 25GB between USB 1.0 and 2.0...maybe I just forgot how slow the process was a few years ago, though.

- Yes, the speed is terrific . . . but the standards commitee SCREWED UP AGAIN! They should have increased the voltage spec in the power wire from a gutless and semi-useless 5V to FireWire's 12V. There's only a gazillion things you can do with 12V that you can't do with 5V. There are all kinds of devices that can be powered by 12V but not 5V. Many devices have batteries that could be charged by 12V but can't be charged with just . . . 5 . . . gutless . . . limp-wristed . . . volts. And the higher voltage gives you more wattage: FireWire pumps out 15 watts of power, whereas USB 3 will pump out just less than 1/3 of that, 4.5 watts. I'm all in favor of paring the list of connection types from at least 7 (SCSI, Serial Attached SCSI, SATA, eSATA, PATA, FireWire, USB) down to a gloriously universal *ONE*, but that one really needs to have the two central, key features of utility, versatility and convenience: speed and electrical power (hot-swappability is a given).
