We make ghost images of the machines we migrate each day. We PREFER to go via USB DRIVES... because USB 2.0 > NETWORK. Usually. At any rate, we have times where the computer, for whatever reason will go anywhere from 30-120MB/minute instead of the 400MB+/min we're used to.

It COULD be USB 1.1 vs 2.0, BUT we run into this issue on all sorts of laptops and DESKTOPS. All compaq and HP, We start with the 610 series laptops and have the HP 6000s, and we have a wide variety of desktops that also have that issue. Did Compaq/HP release different versions of the same computers that vary on the USB?

Or, is there something we might be doing wrong for the ghost up.Radek:

Sounds like a network congestion problem. Try performing the backup operation in the evening when no other user is logged on to the network, or use better network protocols and hardware.

What network protocols are installed on each computer? Is this a client-server LAN or WAN, or is it a peer-to-peer LAN? Are you USING a hub to connect the nodes within the LAN or WAN? If so, try using a router, instead.

DocRemember that USB tries to be "all things to all MEN" and as such, is only moderately succesful at anything intensive that it's used for.

USB is very processor dependent which is where it falls down. It has to wait it's turn on the bus. Whilst it may be OK for transferring occasional smallish bursts of data, it's not really designed to handle continuous streams.
