An Acard Chip Is Inside
Acard designed one of its own Ultra160 SCSI RAID controllers (see image above). As Ultra320 SCSI is downwards compatible, any Ultra160 device can be placed into the SCSI chain.
Setting up the ARS-3031 in RAID 0 mode with four hard drives makes it easy to exceed the Ultra160 SCSI's available bandwidth (usually < 130 MB/s). However, you won't find these bandwidths very often, since only few application scenarios powered by an insecure RAID 0 array make sense. We expect RAID 0+1 or RAID 5 to be the predominant choices. In this case, the Ultra160 bandwidth will be enough.
