View Full Version : Daisy chaining devices - drives and interfaces

So I have a Digi002 Console with an external firewire drive from OWC. Currently, I'm connected as follows:

MacBook > Digi002 > HD - all via FW400. When I get my 2nd drive this week, I'm planning on connecting this way:

MacBook > HD1 via FW400 > HD2 via FW800 > Digi002 via FW400.

My theory is that it's better to have the drives connected to the computer rather than the interface in case the interface fails - which seems to be more likely than a drive failing. Digidesign has recommended both setups at different times over the past few years.

Any thoughts?

is this 2nd drive going to be used for audio?

The 2nd drive will serve as a backup drive for the first one. Pro Tools won't be allocating audio from it (unless of course drive 1 dies). Been doing a lot of contracted tracking and mixing and having the backup has been a necessity.

Originally, I used the internal drive on my PowerMac (I had a 2nd, dedicated audio drive) and I used the external as a backup. However, because my MacBook smokes the tower, I'm selling it and am going to use a 2nd drive as my backup.

I've used the drive both ways (drive > Digi; Digi > drive). Just wanted to see what opinions were for other interfaces outside of Digidesign.

these are the two that jump out at me. if it were me, i'd try the following two setups and see if one worked better than the other:


mac -> 002 -(fw1)-> audio drive
002 -(fw2)-> backup drive


mac -> audio drive -> 002 -> backup drive

Yeah, I was wondering about that. Unfortunately, my second drive was defective (damn power supplies). So I'll have to test that out this week.

I think the 2nd one would work better - Mac > Audio Drive > 002 > backup drive - mainly because I've had a few issues of the audio drive unmounting when the 002 validates.

M-Audio recommends their audio devices be last in a firewire chain. But I've heard many arguments on both sides about this one.

Hi!

I have a related doubt. I'm waiting for my new Motu Traveler to arrive and I own two USB 2.0 HDs (one 2.5 and one 3.5). I have an iBook 14" (1.2 GHz and 768 MB RAM).

I was thinking about buying a Firewire enclosure, because I need one of them to be my audio drive. However, I wonder if I should stick to USB. I know firewire is better for this kind of stuff, but I wonder if connecting the Motu Traveler in a daisy chain would stall the Motu or the HD. (I only have one Firewire port - 400.)

Any opinions on this subject?

USB 2.0 is fine for up to 24bit/96kHz stereo (two channel) recording. Any more tracks or higher sample rate than that, and you might have problems.

As long as the drive in the enclosure is at least a 7200rpm drive, that is.

Well, one of the drives is 7200 RPM (3.5"), the other is 5400 RPM (2.5"). I will need to record 8 channels at once. The sample rate might go up to 24bit/192kHz, but I'll stick to 96kHz if I have to.

So, should I buy a Firewire enclosure? And if I do, when I daisy chain the drive and the audio interface (Motu Traveler) will the bus be too overloaded?
