[lug] External USB 3.0 SATA docks

I successfully got an inexpensive USB 3.0 storage solution working with
Linux.
I'm using the StarTech.com USB 3.0 to SATA dock with Fedora 16/17
(kernel 3.6.6 or so).
Today I connected the dock to an HP laptop with USB 3.0 and used an old
Seagate 7200.10 250G SATA drive. Copying large ISO files I was able to
achieve approximately 88-93 MB/s. This is about 3 times faster than my
typical USB 2.0 speeds. Palimpsest benchmarks this older, slower drive
at between 63MB/s min and 98 MB/s max, so 93 MB/s is great: near eSATA
speeds minus a little bit for USB overhead.
Palimpsest benchmarks a 2009 era Hitachi 2TB SATA drive at 63 MB/s min,
123 MB/s max, 101 MB/s average using this USB 3.0 dock.
I left the laptop copying about 125G of ISOs to the drive repeatedly
today and no errors were reported. No unexpected disconnects or other
problems. Really happy with this so far and expecting to buy another
one or two for other sites. Hope this information helps someone looking
for a Linux compatible solution.
The StarTech.com dock:

The Syba 2 port USB 3.0 PCI card:
http://www.amazon.com/gp/product/B007PPYXNS/ref=oh_details_o01_s00_i00
Both use ASMEDIA chips so I'm expecting compatibility in the long term.
