I had some similar problems with USB 3.0 on my windows machine as well. I dont know if the problem is with Drobo or not but it does seem to be more picky about USB controllers than any other product I have used.
I know there is an approved list of USB 3.0 card controllers on the Drobo support site somewhere but I’m afraid I dont have the link handy.
Also it’s really hard to come by some of the supported cards here in EU. Had to order the IOGear, PCIE, 2-Port (GIC320U) from the US, which means a massive extra shipping costs for something as lowend as an USB3 pci-e card. Doh.
Well, I just hope it works with Windows 8. In the meantime I’ve been backing up stuff using another computer with native USB3. That still disconnects once in a while so it will only transfer about 1 TB before it disconnects only to reconnect 10s later. Really annoying that you can’t trust it to do a proper backup without babysitting it all the time!
I have thunderbolt on this windows machine. I would just love to tuck the drobo away in the next room with the servers!
Yes, I have Thunderbolt 2 on my windows machine too but Drobo still doesnt support Thunderbolt on Windows. I was quite disappointed about that. I started a thread about it but there seems to be no news or updates about when that will happen. They should really implement Thunderbolt on Windows now to give people another option besides USB 3.0
Okay so an update and maybe it will help others as well.
We bought the IOgear GIC320u that Drobo has on their list of products that work. The only concern I had was that there are no drivers for windows 8.1. But we took the chance.
Windows showed the device but with microsofts own drivers. Even though I tried to install the win7 drivers in compatibility mode it just wouldn’t show up using anything other than microsofts drivers. I couldn’t update the firmware either because of that. Anyways I decided I would just test the drive and so far it has been running smoothly with just microsofts drivers.
So now we are up and running!
With 5 x WD RED 4TB drives it does around 170 write and 200 read.
