Raidon (http:/www.raidon.com.tw) has released new one to four bay, USB 3.0 disk array storage devices. (Just remember that Apple isn’t officially supporting USB 3.0 at this time, so the devices will run at USB 2.0 speeds on Macs.)
However, Raidon has also released two types of USB3.0 PCI Express Cards to both desktop and notebook users for external storage expansion. They will apparently work with MacBook Pros and Mac Pros.
