What does IDE (UDMA-66) represent?

IDE (UDMA-66) is a Parallel ATA transfer mode defining a maximum theoretical raw data rate of 66.7 megabytes per second used in legacy PATA storage devices.

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

Converting helps compare older PATA transfer speeds with modern storage and network throughput rates expressed in standardized SI units.

Are IDE (UDMA-66) speeds always indicative of actual performance?

No, the theoretical maximum speeds may not match real-world sustained transfer rates due to hardware and protocol overhead.
