I wonder how much the chipset and connectors will cost to implement USB 3.0 vs say SAS 3Gb/s (current generation) or SAS 6Gb/s (next generation)?
Adding optical transceivers to each end of the link will dramatically increase the cost of devices as well. How much is a current GBIC, for example? Something like $100-$270 on each end of the link? That tends to make for a very expensive implementation. Given those numbers, a first generation USB 3.0 4 port hub will be $1500, and an external USB3.0 hard disk enclosure will be $500. Even second or third generation will be around $500 for a hub and $300 for an empty enclosure.
