Will the UltraBlock SCSI bridge work with Ultra320 SCSI hard disks?

Yes, the UltraBlock SCSI bridge should be compatible with hard disks including new Ultra320 hard disks.

The SCSI standard requires devices to be backwards-compatible with slower transfer modes, for example, so that new hard disks can be compatible with slower host adapters and vice-versa. The UltraBlock SCSI bridge supports SCSI transfer modes up to Wide Ultra 2 SCSI - also known as Wide FAST-40 - for a maximum transfer rate of 80MB/sec. The UltraBlock SCSI bridge will "negotiate" with the SCSI hard disk to determine a mutually acceptable SCSI transfer mode.
