What does the conversion rate 1 SCSI (Fast Wide) = 0.6060606061 IDE (UDMA-33) mean?

It means that one unit of SCSI (Fast Wide) transfer corresponds to approximately 0.606 of an IDE (UDMA-33) unit based on their maximum theoretical throughput speeds.

Can I directly connect a SCSI (Fast Wide) device to an IDE (UDMA-33) controller?

No, this conversion only compares data transfer rates. The devices use different signaling and bus architectures and are not directly compatible.

Why might actual transfer speeds differ from theoretical conversion results?

Factors such as cable quality, controller capability, device negotiation, and hardware implementation impact achievable transfer speeds.

Common Use Cases

Comparing transfer speeds of old SCSI and PATA storage devices during hardware upgrades.
Benchmarking legacy server and workstation disk subsystem throughput.
Troubleshooting BIOS or controller settings for correct DMA modes on older PCs.
Planning data center migration involving legacy storage technologies.
Assessing throughput differences when choosing cables or controllers for PATA drives.

Tips & Best Practices

Verify device compatibility and controller support before relying on conversion data.
Consider cable quality and hardware implementation, as these affect real-world rates.
Use theoretical conversions as a guide rather than exact throughput guarantees.
Apply conversions for benchmarking or comparison rather than direct hardware interchangeability.

Limitations

Actual transfer speeds vary with physical implementation and device negotiation.
Conversion reflects throughput equivalence, not direct device compatibility.
Signaling and bus architecture differences mean these units are not interchangeable.
Theoretical maximums may not be reached due to legacy hardware constraints.
