What Is This Tool?
This unit converter transforms values from E.P.T.A. 2 (payload) units, which measure application/user data in a specific protocol, to IDE (PIO mode 4), a timing mode used in legacy ATA/IDE storage device transfers. It facilitates comparison and analysis between specialized data payloads and historic storage timing modes.
How to Use This Tool?

Examples
-
10 E.P.T.A. 2 (payload) is equal to approximately 0.5783 IDE (PIO mode 4)
-
100 E.P.T.A. 2 (payload) converts to about 5.7831 IDE (PIO mode 4)
Common Use Cases
-
Measuring and logging message sizes for E.P.T.A. 2 protocol throughput and latency analysis
-
Configuring or diagnosing legacy IDE/ATA drives and system BIOS or driver settings
-
Benchmarking legacy storage device performance for upgrade considerations
-
Conducting protocol analysis and performance tuning in embedded and retro-computing environments
-
Estimating bandwidth and storage requirements for systems using E.P.T.A. 2 payloads
Tips & Best Practices
-
Understand that the E.P.T.A. 2 (payload) unit is protocol-specific and not standardized
-
Use this conversion primarily for comparative and conceptual analysis rather than precise physical measurements
-
Validate your conversion results against specific implementation details when possible
-
Consider system conditions that may influence the timing or payload characteristics
Limitations
-
E.P.T.A. 2 (payload) is defined by proprietary protocol specifications and lacks standardization
-
IDE (PIO mode 4) denotes a timing mode, not a direct measurement of data size
-
Conversion is conceptual and may vary due to differences in hardware, protocols, or environments
-
Accuracy depends on adherence to the particular relationship established by specific implementations
Frequently Asked Questions
-
What does E.P.T.A. 2 (payload) measure?
-
It measures the amount of application or user data carried in a single message defined by the E.P.T.A. 2 data-transfer protocol.
-
Is IDE (PIO mode 4) a measure of data storage?
-
No, IDE (PIO mode 4) represents a CPU-driven timing mode for data transfers between host and storage devices rather than a physical storage unit.
-
Why convert between these units?
-
Converting helps compare specialized protocol payload sizes with legacy storage interface characteristics, useful for performance tuning and system analysis.
Key Terminology
-
E.P.T.A. 2 (payload)
-
A protocol-specific measurement of application data in an E.P.T.A. 2 message, not a standardized unit.
-
IDE (PIO mode 4)
-
A CPU-controlled timing mode for data transfers in ATA/IDE storage devices with a theoretical throughput of about 16.7 MB/s.
