I'm just in the process of setting up a scsi system after trying a card with a burner/reader plex 50 pin combo. I have an older Asus P2B-S and am looking for a hard drive right now. The board's adaptec controller does U2W on the one 68pin so I asked for a cable for it. I got one but other than being a 68 pin, I dont recognize any markings on it that tell me its data rate. Is there supposed to be or is any non-lvd cable capable of up to 40mb/s? I assume I'd need an lvd for 80mb/s?
