This is my first post here, so be gentle. The Setup: I have an HP small form factor dc7700 computer (Specs here: http://www.retrevo.com/search?q=HP dc7700 SFF&rt=sp&modelid=3167477) that I want to use as my NAS box. I have 4 Seagate GoFlex Desk 2TB external hard drives that are USB 3.0 speed. The dc7700 is only capable of USB 2.0. See where I'm going? I bought a SIIG DP USB 3.0 4-Port PCIe i/e card (http://www.siig.com/it-products/usb/adapters/pcie/dp-usb-3-0-4-port-pcie-i-e.html) and put it in the PCI express slot. The card has 3 ports on the back and 1 port internally. I removed a metal plate from one of the unused PCI slots and ran the USB cable from the cards inside port thru the hole to it's 2TB HDD. I obviously connected the other 3 2TB HDD's to the ports on the back of the machine. I installed FreeNAS 8.0.3 onto a Patriot SUPERSONIC PULSE 4 GB Flash drive which is also USB 3.0 but I am out of 3.0 ports at the moment so I plugged it into a port off of the front. The Problem: I connected the 4 drives to the USB 3.0 card and no drives show up when I click on "Create Volume". I even plugged the "optional" SATA power connector to the back of the card; still nothing. I called SIIG, stayed on hold for an hour until they closed last night, and finally opted to leave a voicemail. They called me back today just to tell me they have no Linux/FreeBSD drivers for this product and as far as the Rep knows, no intentions of creating any. I tried to find a Hardware Compatibility List on the FreeNAS site but all lists and references seem to be for older versions of FreeNAS. Bottom Line: Does anyone know of a USB 3.0 adapter that will work with FreeNAS 8.0.3 (64 bit) so I can take advantage of the USB 3.0 speeds that my drives (and Flash Drive) are capable of?
