Hi Rodger --

Thanks for the quick responses. The backup unit is a Overland arcvault
12 w/lto4 drive. The lto4 have,
I think, 120MBps (Native)/240MBps (compressed), so no gain using U320
interface? I'd guess the max thru put
would be 120MBs, with the compressed rate just accomplished because of
data compressing. Sorry to
be thinking out loud here, but this does help!
