ICY DOCK MB559US-1SMB: eSATA Enclosure
 

ICY DOCK has been around for over 12 years now and although they are not a household name, if you have shopped for drive enclosures there is a good chance you have noticed them. In fact, drive enclosures is their one and only business. They specialize in providing a complete lineup of internal and external drive enclosures utilizing various interface technologies. It should not be surprising that they were one of the first companies to market an external enclosure with a eSATA interface.

Same burst speed issue I saw with Antec MX-1

hooking MX-1 to eSATA of Asus does increase performance

I should get the PCI pass thru bracket.

that's what I used, max burst not over 130mb/s
