What is IDE (DMA mode 2)?

It is a legacy Parallel ATA data transfer mode allowing direct memory access with minimal CPU involvement, improving throughput over older PIO modes.

Why convert IDE (DMA mode 2) speeds to terabytes per second?

Converting to TB/s helps express legacy data rates in a modern, standardized unit, facilitating comparisons with current storage and network speeds.

Are there limitations to this conversion?

Yes. The IDE (DMA mode 2) provides much lower bandwidth compared to modern rates, so TB/s results are very small, and the unit difference between terabyte and tebibyte can introduce slight discrepancies.

How to Convert from IDE (DMA mode 2) to Terabyte/second [TB/s]

Convert data transfer rates from the legacy IDE (DMA mode 2) to terabyte per second (TB/s) using a straightforward conversion tool, aiding in comparing older interfaces with modern high-speed data transfer rates.

Key Terminology

IDE (DMA mode 2): A legacy Parallel ATA data-transfer mode enabling direct memory access with minimal CPU involvement for better throughput than older PIO modes.
Terabyte per second (TB/s): A unit of data transfer rate indicating the transmission of one terabyte (10^12 bytes) of data every second, used for measuring very high-speed links.
PIO mode: An older data transfer method where the CPU is actively involved in moving data, resulting in higher overhead and lower throughput compared to DMA.
