I don't know of any Linux folks that depend on 1394 for audio. I use it under Windows successfully. It seems to *work* under Linux, meaning well enough to do a little testing, or even record a lot of tracks in the studio in some made up test case, but I don't use Ardour so I cannot comment on whether it's stable enough day inand day out. I've ordered a number of units from http://fwdepot.com. Most have worked with Linux, but not all so I'm very hesitant to really recommend anything. I know my Ice Case drive units have consistently been the best. The Pyro stuff has been OK for hard drives but not for other stuff. Linux 1394 is *only* 5 years old. It still doesn't optimize gap count on a simple 2 device bus even with the newest drivers, or some I'm told.

No, I think that's about the right price. If they use Oxford Semi chipsets, most notibly the 911 for 1394a, then they have been pretty good for most folks. I'm about ready to get a 1394b drive and cardbus adapter and try that out, again mostly in Windows but certainly a bit under Linux... > > Any recommendations or docu welcome. > > cheers, tobias. >
