What Is This Tool?
This converter translates data transfer measurements from the protocol-specific E.P.T.A. 1 (payload) unit, representing user/application data payload sizes, into the IDE (PIO mode 0) unit, which reflects data transfer timing characteristics for legacy ATA/IDE drives.
How to Use This Tool?
-
Enter the value in E.P.T.A. 1 (payload) units you wish to convert
-
Select 'E.P.T.A. 1 (payload)' as the original unit
-
Choose 'IDE (PIO mode 0)' as the target unit
-
Click the convert button to get the equivalent value in IDE (PIO mode 0)
-
Use the result for bandwidth analysis, diagnostics, or device compatibility checks

Examples
-
10 E.P.T.A. 1 (payload) converts to approximately 0.7273 IDE (PIO mode 0)
-
100 E.P.T.A. 1 (payload) converts to approximately 7.2727 IDE (PIO mode 0)
Common Use Cases
-
Calculating throughput and bandwidth for links carrying E.P.T.A. 1 traffic
-
Sizing buffers and memory for devices implementing E.P.T.A. 1 protocol
-
Converting payload sizes for diagnostics, logging, or billing in E.P.T.A. 1 systems
-
Connecting and analyzing data transfer rates on legacy IDE drives with PIO mode 0
-
Supporting firmware development, data recovery, and diagnostics on vintage hardware
Tips & Best Practices
-
Confirm the context of measurement before conversion to ensure relevance
-
Use conversion results when working with legacy or specialized systems requiring IDE PIO mode 0 timing
-
Apply conversions for planning firmware or hardware integration involving both protocols
-
Refer to example conversions to validate input values and results
-
Remember this conversion reflects slow CPU-driven transfers typical of IDE PIO mode 0
Limitations
-
Conversion is based on static timing characteristics of IDE PIO mode 0, a relatively slow transfer method
-
Results may not reflect performance of modern devices using faster DMA modes
-
Primarily applicable to legacy or specialized contexts rather than general modern hardware
-
Does not account for protocol overhead or headers beyond the E.P.T.A. 1 payload size
Frequently Asked Questions
-
What is E.P.T.A. 1 (payload)?
-
E.P.T.A. 1 (payload) is a unit representing the size of user or application data in a single E.P.T.A. 1 frame, focusing on payload length rather than protocol overhead.
-
What does IDE (PIO mode 0) measure?
-
IDE (PIO mode 0) refers to a legacy ATA/IDE data transfer timing mode with slow CPU-driven rates, commonly used for compatibility with old drives and devices.
-
Why convert between E.P.T.A. 1 (payload) and IDE (PIO mode 0)?
-
Conversion helps translate protocol-specific user data sizes to timings consistent with legacy IDE transfer rates, supporting analysis and integration across systems.
-
Is this conversion suitable for modern hardware?
-
No, this conversion targets legacy systems as modern devices typically use faster transfer methods like DMA rather than IDE PIO mode 0.
Key Terminology
-
E.P.T.A. 1 (payload)
-
A protocol-specific unit measuring the size of user or application data in a single E.P.T.A. 1 frame, excluding overhead.
-
IDE (PIO mode 0)
-
A legacy ATA/IDE data transfer timing mode involving CPU-driven read/write processes with low maximum throughput used for old hardware compatibility.
-
Conversion Rate
-
The factor used to translate one unit to another; here, 1 E.P.T.A. 1 (payload) equals 0.0727272727 IDE (PIO mode 0).
