What is IDE (UDMA mode 1)?

IDE (UDMA mode 1) is an Ultra DMA transfer mode in the Parallel ATA interface that delivers a theoretical transfer rate up to about 25 MB/s, commonly used in older PATA drives.

What does T4 (signal) represent?

T4 (signal) is a North American T-carrier high-order trunk signal corresponding to the DS4 rate, carrying multiplexed channels at approximately 274.176 Mbps for legacy telecom backbones.

Why would I convert between IDE (UDMA mode 1) and T4 (signal)?

Converting between these units helps compare vintage computer data transfer rates to historical telecom signals, useful in diagnostics, benchmarking, and legacy system maintenance.
