Hello,
I have 12 hard drives attached to a "ARC-1680 series PCIe to SAS/SATA 3Gb RAID Controller". Only 1 of the 12 cards are able to be assigned and I am unsure why. I do have the raid controller set to JBOD. The two PNY SSD's in the pictures are not connected the raid controller but. And yes for anyone that looks up these drives they are old. Nothing important is being stored on this that is not backed up to the cloud.
