(Saturating the link is fine as long as your performance is good as
well.)  Anyway, the numbers I've read from them show something in the
neighborhood of really terrible:
http://www.linuxjournal.com/article/8149 -- 23.58MB/s reads.  I'd expect
that performance out of a single ATA disk. IOPS is obviously something
different, but I don't believe that article mentions it.
