What is IDE (UDMA mode 4)?

IDE (UDMA mode 4), also known as Ultra DMA/66, is a Parallel ATA transfer mode offering up to about 66.7 megabytes per second using an 80-conductor cable for reliable data movement.

How is a terabyte per second defined in this converter?

A terabyte per second (SI definition) equals 10^12 bytes transferred each second, which corresponds to 8 terabits per second in digital systems.

Why are converted values from IDE (UDMA mode 4) to terabyte/second so small?

Because terabyte/second units reflect extremely high data transfer rates, legacy IDE speeds convert into very small fractional amounts, highlighting the technological gap.
