OK. I wonder what the review I read was talking about. They mentioned the CPU utilization on a Mac was excessive and due to the RAID being handled in software which had seemed odd to me.[/quote]
Whoever wrote that review must have been looking at something else (perhaps the Drobo Copy utility, which is a separate thing altogether).
Drobo requires zero processing on the connected computer. It does all its magic on its own. Drobo Dashboard if it is running, does “talk” to Drobo to get status, but Drobo will work perfectly fine on a system without Drobo Dashboard.*
Drobos connected via iSCSI require an iSCSI Initiator, which may require installation of Drobo Dashboard at least to get the initiator installed.
I figured as much as it wouldn’t make sense on a product like this to be software RAID as that defeats the purpose of the Drobo in my opinion. I have a 5N now and that is what I like about it (despite Mac access issues lately - Windows works fine). I wonder what this review is referring to then: http://macperformanceguide.com/Storage-Drobo5D-cpu-utilization.html
