I'm trying to find a good FW400 drive or drive enclosure that is reliable and fast and works well with OSX 10.4.5. I have never purchased an external drive before so I'm a bit ignorant of some of the criteria. In doing my research I found some references to a chipset called "Oxford 911" which appears to be the bridge between the FW and IDE interfaces. Its performance (in 2001, when most reviews of external drives seem to have last ben made) was supposed to be fantastic and was highly recommended. In 2006 does the Oxford911 chipset really matter anymore? Is there any real discernable differences between drives/enclosures and if so what should I be looking for? (PS. I figure that I could use extra drive speed because I'll be doing a bunch of audio recording and manipulation) Thanks in advance for your responses.
