Continuing from my previous post "G5 & FW 800 PCI card-Woohoo! Thanks Larry and OWC!"
I have ended up wondering if I have an intrinsic firewire problem on my G5?
Dual 2.0/4.5GB (8 ram slots)/OWC PCI FW 800/400/USB 2.0/ OS 10.4.5 plus an OWC Mercury AL FW 800/400/USB 2.0 enclosure housing a Maxtor 300GB drive.
I just ran a test using Intego's Personal Backup to transfer a 7GB DV file.
Here's the log:

The supposed possible transfer speed based on OWC's specs:
"Features & Benefits:
Up to 800Mbps! - The OWC Mercury FireWire 800 PCI Adapter Card has been tested at exceeding 63MB/Sec when using OWC Mercury Elite Pro FireWire 800 hard drives. That's incredible speed!"
The indicated speed of transfer seems to be very far under the possible FW 800 transfer speed according to the spec and the input I had from Carthaigh, who did some checking on his Powerbook.
Since I have been getting the shaft from CompUSA and Apple on my Applecare (see previous topic), I'm wondering if there really is a new or ongoing problem with my G5's firewire performance.
I'd appreciate any helpful input, especially if it would lead to my being able to get Apple to pony up a replacement.
Thanks for your thoughts,
GeneL
