Hey all, just plunked down on a Drobo and 4 WD Green 1.5TB disks.
So far the units been great, breeze to set up, software and firmware updates went fine.
Initial moving in has been okay, but writing transfer speeds have been in decline as I go. First copy batch, roughly 250GB went by at a respectable ~30MBps. More recent copy jobs though start out at a nice transfer speed, then stall out, have occasional spurts of a few megs here and there, then the flow picks up again, craps, out, the cycle continues. Net result is copy jobs are taking 5 to 10 times longer now.
Reads fly by at very constant 30. Probably was saturating the volume I was copying to.
Like I said, I gave Drobo four 1.5TB disks to use. Drobo is set to make a 16TB HFS+ volume. I connect via FireWire 800 to Mac systems (tried two for science - same results.) Drobo, Dashboard and system logs indicate no issues. Drobo’s log is clearly not for my eyes.
