Looks like Intel is trying to scramble a rally for USB 3.0 as an
alternative to External SATA/SAS. The 4 Gb/second bandwidth should
balance out the arbitration and negotiation to be almost as fast as
the 3 Gb SATA-II interface, but not as fast as the 4 GB and 10 GB
fiber-channel interfaces and other SAN interfaces. Although it's
faster that 1 Gigabit Ethernet, most SAN controllers do most of the
indexing and file-system management which reduces the total bandwidth
required for equivalent functionality, especially with Ext3 and NTFS
filesystems. In addition, the external SAN storage is platform
independent, often running embedded Linux, which means the same drives
and partitions could be shared by Linux AND Windows/Vista.

USB-3.0 can't afford to be playing these kinds of games. It just
drives competitors, who are using ARM and other applications, as well
as those who are less than thrilled with Microsoft at the moment, to
consider other alternatives such as E-SATA-II, GigabitEthernet, or
Infiniband, all of which are supported by Linux and are published
standards.
