ATTO ExpressPCI Ultra2 adapters unleash the power of Ultra2 SCSI by eliminating
SCSI management overhead and increasing SCSI transfer rates, while providing an
easy performance upgrade path for your existing SCSI-1, SCSI-2 and SCSI-3 drives.
Bus Master capabilities allow ATTO ExpressPCI SCSI host adapters to transfer data
directly between the computer’s RAM and the SCSI bus without using the CPU. This
frees all the CPU’s processing power for running demanding applications.
