What does IDE (UDMA mode 0) represent?

IDE (UDMA mode 0) is an Ultra DMA transfer mode for Parallel ATA devices, defining interface timing with a nominal max data transfer rate of about 16.7 MB/s.

How is SCSI (Sync) different from IDE (UDMA mode 0)?

SCSI (Sync) uses synchronous transfers with a negotiated clock for higher throughput and deterministic timing compared to the legacy IDE (UDMA mode 0) asynchronous interface.

Can I rely on this conversion for exact performance analysis?

No, the conversion shows nominal maximum rates and does not account for real-world overhead, so actual performance may differ.

How to Convert from IDE (UDMA mode 0) to SCSI (Sync)?

Convert data transfer rates between IDE (UDMA mode 0) and SCSI (Sync) to compare legacy PATA/IDE throughput with synchronous SCSI performance for diagnostics and system migration.

Key Features

Converts data transfer rates between IDE (UDMA mode 0) and SCSI (Sync).
Based on nominal maximum data transfer rates for legacy and server storage interfaces.
Browser-based and easy to use for quick comparisons and troubleshooting.
Supports system migration and hardware diagnostics by relating interface speeds.

Examples

1 IDE (UDMA mode 0) equals approximately 3.32 SCSI (Sync).
2 IDE (UDMA mode 0) convert to about 6.64 SCSI (Sync).

Common Use Cases

Comparing throughput between legacy PATA/IDE drives and synchronous SCSI storage.
Troubleshooting DMA timing and data transfer performance in BIOS or drivers.
System migration assessments when moving from IDE to SCSI-based storage solutions.
Server storage management and tuning in environments using both IDE and SCSI devices.

Tips & Best Practices

Use this conversion to understand relative interface speeds rather than exact real-world performance.
Consider overhead and hardware specifics as this tool uses nominal maximum values.
Leverage the conversion while planning upgrades or troubleshooting legacy devices.
Compare results with actual device specifications for more accurate diagnostics.

Limitations

The conversion reflects nominal maximum transfer rates and excludes protocol overhead or inefficiencies.
Performance differences due to transfer mode negotiation and interface design mean exact equivalence may not occur.
Real operational throughput can vary between devices despite the numerical conversion provided.
