I figured that since Apple had been using it for years, and it is an IEEE standard, that Firewire would be more reliable than USB. I was also a bit wary as the USB disk drivers on SuSE gave warning messages saying they might not be very reliable. I first used Firewire external drives in 2003 on whatever was the current version of SuSE Pro at the time, and on a FreeBSD 4.8 system, and have Firewire drives on several SuSE systems up to SuSE Linux Enterprise 10. The FreeBSD machine has never shown any problems with its FW drive, but the SuSE systems often seem to stop talking to the drive for no apparent reason. At this time, most of our Linux boxes are running USB 2.0, and the external Firewire-only drives are all on our Macs which seem to have far better FW support than Linux.
