What does IDE (UDMA mode 3) represent?

IDE (UDMA mode 3) is an Ultra DMA transfer mode for Legacy Parallel ATA (PATA) interfaces providing a maximum theoretical transfer rate of about 44.4 MB/s.

How is a kilobyte per second defined here?

A kilobyte per second (SI definition) equals 1000 bytes per second and uses decimal prefixes, differing from binary-based units.

Supports clear and straightforward interpretation of hardware throughput values.
Browser-based and easy to use with no installation required.

Examples

2 IDE (UDMA mode 3) equals 100000 kilobyte/second (SI def.).
0.5 IDE (UDMA mode 3) equals 25000 kilobyte/second (SI def.).

Common Use Cases

Comparing or specifying throughput for legacy PATA/IDE hard drives in datasheets or documentation.
Configuring drive transfer modes in BIOS or firmware for older PC systems.
Interpreting benchmark results and troubleshooting PATA/IDE storage devices.
Reporting simple file transfer speeds in web and application environments.
Describing data throughput of embedded devices or serial links using SI units.

Tips & Best Practices

Always verify that units used for comparison share the same decimal or binary base to avoid confusion.
Use this conversion for interpreting theoretical transfer rates, not exact real-world speeds.
Refer to device datasheets or system documentation when configuring legacy PATA/IDE modes.
Be aware of overhead or hardware limitations that can affect actual transfer speeds.
Use SI units for clarity when communicating data rates to general audiences.

Limitations

The IDE (UDMA mode 3) rate represents a theoretical maximum; actual speeds may be lower.
Kilobyte/second (SI) uses a decimal base, differing from binary units like kibibyte per second (KiB/s).
Comparison with binary-based units requires caution as values may not directly align.
This tool does not reflect runtime performance variations due to system or hardware factors.
