What does IDE (UDMA-66) represent in data transfer?

IDE (UDMA-66) is a legacy Parallel ATA transfer mode defining a maximum raw data rate of 66.7 megabytes per second using an 80-conductor PATA cable.

Why convert IDE (UDMA-66) to bit/second?

Converting to bit/second allows comparing legacy drive speeds to network and communication link speeds using a fundamental unit of data rate.

Are the conversion results always exact in real use?

No, actual data transfer rates may be lower due to device health, cable quality, and overhead not accounted for by the theoretical conversion.
