What does IDE (UDMA mode 2) represent?

IDE (UDMA mode 2) is an Ultra DMA mode for PATA interfaces, known as ATA/33, with a theoretical max transfer rate around 33.3 megabytes per second.

Why convert IDE (UDMA mode 2) speeds to terabyte per second?

Converting these legacy speeds to terabyte per second helps compare older hardware data rates against modern high-speed storage and network standards.

Does this conversion reflect actual transfer rates?

No, the conversion is based on theoretical max rates and does not include real-world overhead or sustained transfer speeds.

Facilitates performance comparison between older PATA devices and current high-speed storage interfaces.
Browser-based and easy to use for quick data rate translation.
Supports benchmarking and troubleshooting scenarios involving ATA/33 transfer mode.

Examples

10 IDE (UDMA mode 2) converts to about 0.000300133 terabyte per second.
50 IDE (UDMA mode 2) converts to approximately 0.001500665 terabyte per second.

Common Use Cases

Configuring or identifying legacy PC BIOS or drive-controller settings to enable IDE UDMA mode 2 performance.
Interpreting legacy disk throughput or benchmarking results involving ATA/33 transfer rates.
Troubleshooting compatibility or driver issues on older PATA-based systems.
Sizing and planning data center infrastructure by relating historical transfer speeds to modern rate units.

Tips & Best Practices

Verify the transfer mode being measured matches IDE (UDMA mode 2) for accurate conversion.
Use the converter to contextualize legacy data rates in modern units rather than for precise bandwidth planning.
Combine this conversion with other diagnostic data when troubleshooting older hardware performance.
Remember this tool reflects maximum theoretical speeds, not sustained or real-world throughput.

Limitations

The conversion reflects theoretical maximum IDE UDMA mode 2 speeds, not accounting for overhead or inefficiencies.
Transfer rates of IDE (UDMA mode 2) are much lower than typical terabyte/second rates, limiting practical direct comparison.
Not suitable for exact performance measurements in high-bandwidth environments requiring real-time data.
