cMP can't see samsung 850 msata

[cburrows]

Hello,

Several hours of searching the web has left me scratching my head on this one... I've recently purchased an Addonics mSata 4 slot PCIe card and a Samsung 850 evo mSata 250gb SSD drive. Everything I've read online implies that this SSD should just mount in OSX? I've triple checked to verify that both the card and SSD are installed correctly, and the light on the card lights up indicating that it is getting power. This is on a 2009 cMP 4,1 running 10.11 OSX

I just can't figure out why Disk Utility cannot see the SSD? Is it possible that I need a driver for the Addonics card? If so I cannot find any drivers for OSX despite numerous people in fact using this drive in their Macs. Did I simply buy the wrong drive for the mSata card?

Below are links to the Addonics card, as well as a link to the writeup that convinced me to purchase the Addoncs card in the first place. Any help is greatly appreciated. Thanks.

It works with no driver. see this thread

By default it works in Yosemite as 4 JBODs. you have to run Windows/Bootcamp to use the utility to set the Addonics card to work as a RAID0 drive, at which point it works just like the OWC Accelsior, like a single drive in OS X.
