  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

On our first day of this latest job we dumped the drives connected only through FW800 with bus power. Today, we hooked up DC and saw about a twofold increase in the speed of the file dumps. Just sayin'.....

the only difference i've seen in transfer speeds relates to the system you're running the data through and destination drive speeds:

powermac g5 fw800 with dc power - about 40MB/sec to internal 7200 rpm sata

mac pro quad 2.8 ghz fw800 bus powered - just under 100MB/sec theoretical limit to 2.5TB raid 0 (i don't believe it myself but it did take about 10 minutes to move over 50GB of r3d data so...)

the latest mac pros run fw800 over pci bus unlike all previous mac pros:
