What Is This Tool?
This tool enables you to convert data transfer rates from IDE (DMA mode 2), a legacy Parallel ATA data transfer mode, to SCSI (LVD Ultra160), a parallel SCSI interface standard. It helps compare or translate transfer speeds for legacy storage devices.
How to Use This Tool?
-
Enter the numerical value in IDE (DMA mode 2) units that you want to convert.
-
Select IDE (DMA mode 2) as the source unit and SCSI (LVD Ultra160) as the target unit.
-
Click convert to get the equivalent value in SCSI (LVD Ultra160) units.
-
Use the result to compare or analyze legacy storage performance.
Key Features
-
Supports conversion from IDE (DMA mode 2) to SCSI (LVD Ultra160) units
-
Helps benchmark and assess legacy storage interface throughput
-
Browser-based and easy to use for quick conversions
-
Shows conversion based on a fixed ratio
-
Includes examples demonstrating typical conversions
Examples
-
5 IDE (DMA mode 2) converts to 0.51875 SCSI (LVD Ultra160)
-
10 IDE (DMA mode 2) converts to 1.0375 SCSI (LVD Ultra160)
Common Use Cases
-
Configuring or diagnosing legacy PATA/IDE hard drives and optical drives using DMA modes
-
Negotiating firmware or BIOS transfer modes on older systems balancing compatibility and performance
-
Benchmarking or troubleshooting legacy storage interfaces based on transfer rates and CPU usage
-
Specifying data-transfer limits for internal disk arrays and RAID controllers using SCSI
-
Evaluating throughput of tape drives and backup systems with parallel SCSI interfaces
-
Planning migration or compatibility of legacy storage buses in data centers
Tips & Best Practices
-
Use this converter to get theoretical equivalences in transfer rates between two legacy interfaces.
-
Consider this conversion as one factor among others when assessing storage performance.
-
Combine results with real-world testing to understand practical throughput and system behavior.
-
Verify device and driver conditions as they can affect actual speeds beyond the conversion.
Limitations
-
Both IDE (DMA mode 2) and SCSI (LVD Ultra160) are legacy technologies with limited relevance to modern SSD, SATA, or SAS drives.
-
The conversion ratio does not include considerations of latency, command queuing, or operational overhead.
-
Actual throughput depends on hardware conditions, driver implementations, and configuration, so values are theoretical.
Frequently Asked Questions
-
What does IDE (DMA mode 2) mean?
-
It is a Parallel ATA data-transfer mode enabling devices to move data directly to memory with minimal CPU use, part of older PATA/IDE standards.
-
What is SCSI (LVD Ultra160)?
-
SCSI (LVD Ultra160) is a parallel SCSI interface using Low Voltage Differential signaling, providing up to 160 MB/s data transfer rates.
-
Why convert between IDE (DMA mode 2) and SCSI (LVD Ultra160)?
-
Users convert to compare or translate legacy transfer rates for benchmarking, migration planning, or understanding storage interface performance.
Key Terminology
-
IDE (DMA mode 2)
-
A Parallel ATA data-transfer mode letting devices move data directly to system memory with low CPU load, used in legacy PATA/IDE systems.
