What Is This Tool?
This converter allows you to translate data transfer rates between SCSI (Sync), a high-throughput server storage standard, and IDE (UDMA mode 2), a legacy PATA transfer mode, facilitating performance assessment and compatibility analysis.
How to Use This Tool?
-
Enter the amount of data transfer rate in SCSI (Sync) units.
-
Select SCSI (Sync) as the source unit and IDE (UDMA mode 2) as the target unit.
-
Calculate the equivalent IDE (UDMA mode 2) transfer rate using the conversion rate.
-
Review the results for performance comparison or troubleshooting.
Key Features
-
Converts data transfer rates from SCSI (Sync) to IDE (UDMA mode 2).
-
Supports legacy and server-grade storage interface units.
-
Uses the official conversion factor based on negotiated transfer modes.
-
Ideal for comparing throughput between different storage protocols.
Examples
-
1 SCSI (Sync) equals approximately 0.1515 IDE (UDMA mode 2).
-
10 SCSI (Sync) correspond to about 1.515 IDE (UDMA mode 2).
Common Use Cases
-
Compare data transfer speeds between high-performance SCSI storage and legacy PATA devices.
-
Assist in configuring or diagnosing legacy PC BIOS or drive-controller settings for ATA/33.
-
Evaluate benchmark results involving devices with UDMA mode 2 capabilities.
-
Troubleshoot compatibility or driver issues in PATA systems.
Tips & Best Practices
-
Use this conversion to understand relative throughput, not exact sustained speeds.
-
Consider hardware and driver environments as they can affect actual transfer performance.
-
Apply conversions mainly for legacy or specialized devices, not modern interfaces.
-
Use consistent units when comparing device performance to avoid confusion.
Limitations
-
Conversion rates represent theoretical or negotiated modes, not guaranteed sustained speeds.
-
Results may vary due to hardware, driver, or environmental factors.
-
Applicable mostly for legacy storage devices; modern protocols like SATA or NVMe are excluded.
Frequently Asked Questions
-
What does SCSI (Sync) mode mean?
-
SCSI (Sync) indicates a synchronous transfer mode where data moves in step with a negotiated clock, enabling higher throughput and predictable timing between devices.
-
What is IDE (UDMA mode 2)?
-
IDE (UDMA mode 2) is an Ultra DMA transfer mode for legacy PATA devices offering up to about 33.3 megabytes per second transfer rate with a specific timing standard.
-
Why convert from SCSI (Sync) to IDE (UDMA mode 2)?
-
Converting helps compare speeds and assess compatibility between server-level SCSI storage and legacy PC interfaces during configuration or troubleshooting.
Key Terminology
-
SCSI (Sync)
-
A synchronous transfer mode in the SCSI protocol using a negotiated clock for higher throughput and consistent timing.
-
IDE (UDMA mode 2)
-
An Ultra DMA mode for Parallel ATA interfaces, also known as ATA/33, with transfer rates up to approximately 33.3 MB/s.
