Rating: 5/5 Perfect Solution July 18, 2016 I got this enclosure in to expand my JOBD backup system as my storage solutions grow. I was using an older eSATA card that wasn't compatible. It only supported port splitting up to 2x (1 eSATA port to 2 drives). but once I got the a compatible eSATA card that would split 1:4 for my MacPro5,1 this enclosure has been perfect.

Proper card is part number NWTMXPCIE6GRS4E from Newer Technology.

Rating: 3/5 pie card it ships with NOT COMPATIBLE WITH YOSEMITE March 30, 2015 haven't gotten it working yet because the pcie card is not compatible with Yosemite

Response from MacSales.com, Marketing March 31, 2015 The unit as listed is compatible with any OS, including Yosemite, with a properly selected controller card. We do not advertise this enclosure as coming with a controller card. In all fairness, we are of the opinion that the unmentioned freebie card for Windows shouldn't impact the perception of the actual product as advertised.
