Asynchro- nous data transfers support up to 2 MBytes/sec, synchronous transfers support up to 5 MBytes/sec, and Fast synchronous trans- fers support up to 10 MBytes/sec. Devices using different trans- fer rates can all be used on the same SCSI cable. The AHA-1740A/1742A/1744 is both SCSI-1 and SCSI-2 compatible, and supports both SCSI-1 and SCSI-2 devices adaptecEISA-to-Fast SCSI Host Adapter OverviewInstallation Software Table 1-1.
