What is IDE (UDMA mode 4)?

IDE (UDMA mode 4), also known as Ultra DMA/66, is a Parallel ATA transfer mode in the IDE/ATA standard used for moving data between drives and hosts at a theoretical speed of about 66.7 megabytes per second.

What does T2 (signal) represent?

T2 is a legacy digital carrier level from the North American T-carrier system transmitting data at about 6.312 megabits per second, historically used for medium-capacity telecom leased lines.

Why convert from IDE (UDMA mode 4) to T2 (signal)?

Users convert these units to compare or translate data rates between legacy computer storage interfaces and historic telecommunications transmission speeds for benchmarking or analysis.
