What does IDE (UDMA mode 0) represent?

IDE (UDMA mode 0) is an Ultra DMA transfer mode 0 for PATA devices specifying interface timing with a nominal maximum raw data transfer rate around 16.7 MB/s.

What is SCSI (Ultra-2)?

SCSI (Ultra-2) is a parallel SCSI standard using Low Voltage Differential signaling to support higher data transfer performance and longer cable lengths than earlier SCSI versions.

Can this converter calculate exact real-world data transfer speeds?

No, it converts nominal maximum transfer rates without accounting for protocol overhead, signaling differences, or actual performance variations.
