Today's computing applications continue to place incredible strain on the host PCI bus and storage subsystem. In an ongoing effort to bring new heights of performance and reliability to today's professional applications, ATTO is pleased to introduce the ATTO ExpressPCI UL4D with PCI-X ... alleviating PCI bus bottlenecks. Leveraging this latest in SCSI storage connectivity, the UL4D delivers up to 640 MB/sec. data throughput - making it twice as fast as currently available SCSI host adapters. The UL4D's blazing fast speed, plus the advantage of the new PCI-X bus interface and improvements in the SCSI standard, enable it to deliver the high bandwidth required in data-intensive environments.
