LVD is low voltage differential. It describes the SIGNAL that travels along the cable. The LVD style gives you better signal integrity -> lng cable distances and higher speed.

The 80pin SCA connector will typically need an 80pinSCA to 68pin UWScsi to connect to a standard card. There are SCA cards out there but they are extra bucks.

The only big difference between U320 and U160 (beyond the obvious badnwidth difference) is that most/many U320 cards are 64bit PCI cards -- so you need a good server board for those.

Also note that there is a BIG difference between the standard 68pin and the 68pin LVD. You can't mix and match. So if your drive is LVD then you a> need to make sure your card has a LVD channel on it, and b> need to make sure you hook up to that channel.

The size of the drive (3.5 or 5.25) has no bearing on the interface, speed, etc.
