What is IDE (PIO mode 4)?

IDE (PIO mode 4) is a CPU-controlled Programmed Input/Output timing mode used by older ATA storage devices, defining how data transfers are managed between the CPU and drive.

What does T1 (payload) represent?

T1 (payload) is the usable data throughput of a North American T1 digital carrier, representing 24 voice channels at 64 kb/s each, totaling 1.536 Mbps excluding overhead.

Why convert between IDE (PIO mode 4) and T1 (payload)?

Conversion helps compare legacy computer storage performance with telecom bandwidth for tasks such as diagnostics, planning, and legacy system compatibility assessment.

How to Convert from IDE (PIO mode 4) to T1 (payload)
