Ditto. I've been running a DroboPro with eight 1.5TB WD drives and the device has been running fine connected via iSCSI to a Mac mini and shared across the network via NFS. It's not loud, not silent but not loud. Read/write speeds are perfectly satisfactory, although not what I'd get with a software RAID or higher end setup (I get about 25-45MB/s read/writes, but it sounds like I have a different model than he does).

It is a bit unsettling that Drobo advertises these are completely fool-proof in their marketing materials but support, rightfully I may add, recommends routine backups. In the end, it's a JBOD RAID in a pretty enclosure with approachable software. For me, that works.

All I wanted out of my DroboPro was a way to combine eight drives and have an expandable dual-disk redundancy array. It's working like a champ for that.
