    I have 18 Lacie 500 Gig hard drives Daisy Chained together. Its all for a final cut project. Lots of media. I cant help but think this is slowing me down. I have read a bunch of forum posts that say you can have up to 63 drives per chain. I have a additional firewire ports installed, a total of 4 ports, 3 from the card, and 1 normal. this on a G5, powerPC. Dual 2.7 GHz. Total information I need is hooked up is about 8 TB. I need specific suggestions. Thanks!

    "Cable length is limited to 4.5 metres (14.8 ft), although up to 16 cables can be daisy chained using active repeaters; external hubs, or internal hubs are often present in FireWire equipment", and that's just the cable. I know 18 is easily doable. I've read it's something like 60 you can do.

    This is assuming you are using FireWire, of course.

    I could have sworn I've read someone testing this out and getting no less than 90 FW devices chained together, but I've never been able to find that supposed article since.

    This sounds logical:

    "they're all sharing the same firewire bandwidth. So if you're copying a large file to one of the three drives, and then trying to run things off another drive, they'll be sharing the bandwidth and hence slow down."

    There is no way that this was the most practical solution. Drobo anyone?

    Better way is to create a RAID 5 array using SATA or eSATA.

    Would LOVE to see photo (or video).
