The DC-315 SCSI bus provides up to four times the speed of built-in SCSI on previous Macintosh. It provides SCSI bus bandwidth for delivering up to 20MB/s data transfer rate and supports auto SCSI termination. With its high speed 32-bit PCI bus master DMA, the transfer rate is up to 133MB/Sec. And, with PCI 2.1 compliant, it is PCI Power Management supported. Command Tag Queuing and Sync./Async. Transfer are supported as well. As we know MAC G3 is built with MAC OS8.0 and MAC G4 is built with MAC OS9.0, and Tekram DC-315 can be operated under Mac OS, as well as PC OS. In addition, the features of On-Board Scatter/Gather Cache and Intelligent Scatter/Gather Engine are noted for performance enhancement.

It is without doubt that SCSI continues to be the I/O protocol of choice for the fastest and reliable peripheral devices. From the chip level to the adapter level design, Tekram's outstanding R&D capability is evidenced by the release of DC-315. In DC-315, Tekram adopts its own SCSI chip and driver device, which optimizes the compatibility and flexibility to meet diverse market demands. A card like DC-315 provides the high speed and quality that graphics professionals seek.
