What does IDE (UDMA mode 4) mean?

IDE (UDMA mode 4), also known as Ultra DMA/66, is an older Parallel ATA transfer mode used to move data between a drive and host at speeds up to about 66.7 megabytes per second.

Why convert IDE speeds to terabyte per second?

Converting IDE transfer rates to terabyte per second helps compare legacy hardware data speeds with modern high-speed storage and network technologies.

Is the IDE (UDMA mode 4) transfer speed exact?

No, IDE (UDMA mode 4) speed is a maximum theoretical value and actual throughput may vary due to system factors like cable quality and overhead.
