What does SCSI (LVD Ultra80) represent?

It is the Low Voltage Differential version of Ultra2 SCSI, providing up to 80 MB/s raw data transfer over a wide 16-bit bus with improved noise immunity.

What is IDE (PIO mode 2)?

It is an ATA/IDE timing specification for CPU-driven data transfers used by older IDE drives to control programmed I/O cycles.

Why convert between these two units?

To translate data transfer rates for comparing or diagnosing legacy systems where both high-speed SCSI and older IDE technologies are involved.

How to Convert from SCSI (LVD Ultra80) to IDE (PIO mode 2)?

Convert data transfer rates between SCSI (LVD Ultra80) and IDE (PIO mode 2) to assist with legacy system diagnostics, configuration, and performance analysis.
