Anyone want to try this and report back?

In a nut shell:
“…changing the firewire drivers to the ‘Legacy’ versions. To do this, go to Device Manager and find your firewire device. In my case it was ‘1394 OHCI Compliant Host Controller’. Right-click it and hit ‘Update Driver Software’, then ‘Browse my computer for driver software’ and ‘Let me pick from a list of device drivers on my computer’. Select the version with (Legacy) at the end and click-through to install it…”

Reportedly a HUGE gain in transfer speeds. No Unibrain drivers needed.

Ok… I got brave over the holidays, backed up my Drobo and switched to the Legacy Firewire driver. Guess what… it works! I also set the Drobo disk device in device manager to “Better performance” from “Quick Removal”. Between that and my post on how I got the Drobo to not go to sleep; my Drobo has been working flawlessly. I’m now getting decent throughput (not full FW800, but better then USB/FW400).

Hope this helps someone else.

What are your read/write speeds now in MB/sec?

I tried the UBCore FW drivers and they quite helped a bit.

I’m getting anywhere from 30 to 70 MBps.
