What does IDE (UDMA mode 1) represent?

IDE (UDMA mode 1) is a legacy Ultra DMA transfer mode for Parallel ATA interfaces, defining a theoretical maximum raw transfer rate of about 25 MB/s on older PATA devices.

What is the meaning of T1Z (payload)?

T1Z (payload) refers informally to the user-data portion of a T1/DS1 telecommunications circuit, representing the nominal user bandwidth excluding framing overhead.

Why convert between IDE (UDMA mode 1) and T1Z (payload)?

Converting these units helps compare data transfer capabilities of vintage IDE devices with the usable bandwidth of T1 telecom links, assisting in benchmarking, capacity planning, and troubleshooting.
