What does IDE (UDMA mode 3) represent?

IDE (UDMA mode 3) is an Ultra DMA transfer mode for Parallel ATA (IDE) interfaces with a theoretical maximum raw transfer rate of about 44.4 MB/s, used primarily in legacy PATA/IDE drives.

Why convert IDE (UDMA mode 3) rates to megabyte/second?

Converting helps compare legacy data transfer speeds to modern units familiar in current storage technology benchmarks and documentation.

Is the conversion from IDE (UDMA mode 3) to MB/s exact for real-world speeds?

No, the conversion reflects ideal or theoretical throughput rather than sustained actual performance, which can vary due to overhead and device specifics.
