What does IDE (UDMA-66) represent?

IDE (UDMA-66) refers to a Parallel ATA transfer mode specifying a maximum theoretical raw data rate of 66.7 megabytes per second on legacy PATA devices.

Why convert IDE (UDMA-66) speeds to megabit per second (SI def.)?

Converting helps relate older PATA device transfer rates to modern network data rate units for easier benchmarking and compatibility comparisons.

Does the conversion represent actual real-world transfer speeds?

No, the conversion is based on theoretical maximum rates; actual speeds can vary due to overhead, hardware limitations, and environmental factors.

Limitations

IDE (UDMA-66) rates reflect theoretical maximum raw data transfer, not actual sustained speeds.
Megabit/second (SI def.) measures network throughput and inherently includes overhead not present in IDE transfer rates.
Conversion assumes ideal conditions and may not capture real-world hardware or protocol constraints.
