3 ware Architectural Advantage Multiple independent (S)ATA 150 Mbytes per second buses Drive failures isolated to a single drive, port, or cable More drives decreases latency & scales performance Dedicated port and cable gives each drive equal priority Single shared 160/320 Mbytes per second bus SCSI Adapter Shared cable lowest drive ID has priority Any drive failure can bring down entire bus 160 - 320 MB/sec SCSI Bus Parallel increases latency and stops scaling around 4 to 5 devices
