What Is This Tool?
This online converter helps translate data transfer rates from IDE (DMA mode 2), a legacy parallel ATA transfer mode, into modem (1200) units which represent early modem speeds in bits per second. It supports understanding, benchmarking, and comparing storage and communication technologies.
How to Use This Tool?
-
Enter the data transfer value in IDE (DMA mode 2) units
-
Select modem (1200) as the output unit
-
Click the convert button to view the equivalent modem (1200) speed
-
Use the results for performance comparison or diagnostics

Limited to legacy contexts; modern hardware uses different standards
Frequently Asked Questions
-
What is IDE (DMA mode 2)?
-
IDE (DMA mode 2) is a data-transfer mode in legacy parallel ATA devices that enables direct memory access with higher throughput and less CPU load compared to older modes.
-
What does modem (1200) represent?
-
Modem (1200) is a legacy measure referring to a modem with a nominal data rate of 1,200 bits per second, typically used in early dial-up communications.
-
Why convert from IDE (DMA mode 2) to modem (1200)?
-
Conversion helps users compare data-transfer speeds of parallel ATA devices with early modem speeds for benchmarking, legacy system analysis, and historical studies.
Key Terminology
-
IDE (DMA mode 2)
-
A Multiword DMA mode in legacy PATA interfaces allowing efficient data transfer with minimal CPU load.
-
Modem (1200)
-
A typical early serial modem speed of 1,200 bits per second representing legacy telecommunications data rates.
-
