What does IDE (UDMA mode 1) represent in data transfer?

IDE (UDMA mode 1) is an Ultra DMA transfer mode for Parallel ATA interfaces that defines a maximum theoretical transfer rate for older PATA devices.

Why convert IDE (UDMA mode 1) speeds to bit/second?

Converting to bit/second allows comparison of legacy transfer rates with modern network speeds expressed in bits per second.

Does the conversion reflect actual transfer speeds?

No, the conversion uses the theoretical maximum rate; actual throughput may be lower due to hardware and signal quality.
