What does IDE (DMA mode 1) represent?

IDE (DMA mode 1) is a Direct Memory Access transfer mode for IDE/ATA storage devices allowing moderate-speed data transfers with minimal CPU involvement.

What is STS3 (payload)?

STS3 (payload) refers to the user-data portion of a SONET STS-3 frame, representing the available bytes for carrying client traffic in a telecom transport channel.

Why convert IDE (DMA mode 1) to STS3 (payload)?

Converting helps compare legacy storage device transfer rates with modern SONET payload capacities for system compatibility, network provisioning, and capacity planning.
