What Is This Tool?
This converter allows you to translate values from the E.P.T.A. 2 (payload) measurement, specific to a data transfer protocol, into IDE (UDMA mode 2) units used in legacy PATA/IDE interfaces. It helps relate message payload sizes to legacy transfer timing.
How to Use This Tool?
-
Enter the value in E.P.T.A. 2 (payload) units you want to convert.
-
Select E.P.T.A. 2 (payload) as the input unit and IDE (UDMA mode 2) as the output unit.
-
Click the convert button to get the equivalent value in IDE (UDMA mode 2) units.
-
Review the results to understand data transfer equivalencies between the two units.
Key Features
-
Supports conversion between E.P.T.A. 2 (payload) and IDE (UDMA mode 2) units.
-
Based on the specified conversion rate of 1 E.P.T.A. 2 (payload) = 0.0290909091 IDE (UDMA mode 2).
-
Useful for analyzing and comparing data transfer capacities and performance of legacy hardware.
-
Browser-based tool requiring no installation or advanced setup.
Examples
-
10 E.P.T.A. 2 (payload) converts to approximately 0.290909091 IDE (UDMA mode 2).
-
50 E.P.T.A. 2 (payload) converts to approximately 1.454545455 IDE (UDMA mode 2).
Common Use Cases
-
Measuring or logging payload sizes in E.P.T.A. 2 protocol messages for throughput analysis.
-
Configuring older PATA devices to achieve ATA/33 transfer settings using IDE (UDMA mode 2).
-
Benchmarking and comparing legacy disk data rates that report UDMA mode 2 speeds.
-
Troubleshooting legacy hardware compatibility by relating protocol payloads to transfer modes.
Tips & Best Practices
-
Use this tool to relate protocol-specific payload sizes to standard transfer modes for clearer performance insights.
-
Understand that E.P.T.A. 2 payload definitions may vary by implementation, so verify specifications carefully.
-
Consider that IDE (UDMA mode 2) represents theoretical maximum speeds and actual rates can be lower.
-
Apply conversions mainly within contexts dealing with legacy systems and embedded hardware development.
Limitations
-
E.P.T.A. 2 (payload) is not an externally standardized unit; definitions depend on specific implementations.
-
IDE (UDMA mode 2) indicates a maximum transfer capability; real-world throughput may differ due to overhead or conditions.
-
The linear conversion assumes correlation of payload size to transfer rate but may not be exact for all cases.
Frequently Asked Questions
-
What does E.P.T.A. 2 (payload) represent?
-
It denotes the amount of application or user data within a single message in the E.P.T.A. 2 data-transfer protocol, defined by that protocol's unique specifications.
-
What is IDE (UDMA mode 2)?
-
IDE (UDMA mode 2), also known as ATA/33, is a transfer mode for PATA/IDE interfaces with a theoretical maximum transfer rate near 33.3 MB/s, representing a timing profile for reliable data exchange.
-
Why convert E.P.T.A. 2 (payload) to IDE (UDMA mode 2)?
-
Conversion helps compare custom protocol message sizes to legacy disk interface transfer rates, aiding performance analysis and hardware compatibility assessments.
Key Terminology
-
E.P.T.A. 2 (payload)

-
IDE (UDMA mode 2)
-
An Ultra DMA mode for PATA/IDE interfaces (ATA/33) indicating a transfer timing profile with a maximum theoretical rate of approximately 33.3 MB/s.
