OK, so Drobo will support USB 3 and Thunderbolt. What will it matter if it still has transfer speeds approaching 3.5" floppy speeds? They need to address the throughput of the device, the reliability of the device, and the proprietary nature of the device.
They don't WANT to address the proprietary nature. The market for a generic RAID enclosure is not what they're after. They're after an expandable storage pool that will take different sized disks of different brands and now, completely different types. If you don't have those NEEDS, don't buy one. I had exactly those needs.
I can't disagree that they work to improve performance but your floppy disk comment is a huge exaggeration. I encode videos that are on the DROBO to the DROBO and get encode speeds that match what everyone else with my computer (27" iMac i7 3.4) gets according to the Handbrake benchmark threads here. I also process photos from my 5DII and 7D including 20-30 shot panoramas and read/write times have never been a problem on my DROBO S. I understand the original DROBO was extremely slow, but I think they already HAD fixed many of the problems and this new model looks to be a move forward.
