https://community.hpe.com/t5/disk/comparison-with-ultra2/m-p/2493946#M482 I am trying to find a whitepaper comparing ultra2 with ultra3. Can anyone point me in the right direction? <BR /> <BR />Thanks, <BR />Neil.

There's not much to it - Ultra2 is 40MBps low-voltage differential SCSI - Ultra3 is 80MBps low-voltage differential SCSI. They are compatible to each other though, depending on the controller, you may hold back an Ultra3 drive by hooking it up with an Ultra2.
