Short for
RAID on motherboard, a memory system in which every component of the
RAID subsystem is placed directly on the
motherboard. A ROMB system is advantageous because the RAID component of the system is kept separate from the
PCI buses so that the PCI buses do not interfere with RAID traffic and cause
bottlenecking. The motherboard also typically stays cooler than other parts of a computer; therefore, the RAID system works more efficiently and reliably because it too stays cooler.
One disadvantage to a ROMB system is that the hardware is not upgraded easily.
