What is IDE (UDMA-66)?

IDE (UDMA-66), also known as Ultra DMA Mode 4 or ATA-66, is a legacy Parallel ATA transfer mode with a maximum theoretical data rate of 66.7 megabytes per second used for older PATA devices.

Why convert IDE (UDMA-66) to gigabyte per second?

Converting to GB/s standardizes legacy transfer rates into modern units, allowing easier comparison with current storage technologies and performance benchmarks.

Does the converter reflect actual device speeds?

No, conversions are based on theoretical maximum rates; actual device throughput may be lower due to hardware limitations.
