Hey All I just got a drobo, and am pretty disappointed with the speed results. I am using X Bench on a 2 x 3 Ghz Dual-Core Intel Xeon Mac Pro. Connecting via Firewire 800 that came with the drobo. Running the latest firmware and drobo dashboard. There are 4 x 2TB Hitachi Desktar drives in the drobo, with 55% free space. Is this normal for a Drobo?
Here are the results…

I’ve had a 2nd gen Drobo for just over 6 months and am seeing much lower speeds. I haven’t run any diagnostics, but I’ve never seen it go above 3MB/s in practice. It’s sometimes slower than downloading from the internet. I’ve tried USB and FW800 and seen no difference.
I’m running Windows Server 2008 R2 but have had the Drobo connected to Win7 (x86 and x64) and OSX systems as well. I have 3x1TB WD Green drives, and a Seagate 640GB in the Drobo.
Is there something wrong with my unit? It took several hours to copy 30GB from the Drobo to the local drive this weekend, and is driving me crazy.
