What Is This Tool?
This unit converter assists users in translating data transfer values between IDE (DMA mode 2) and SCSI (Fast Ultra Wide) formats, both of which are legacy technologies used in older computing systems.
How to Use This Tool?
-
Enter the value in IDE (DMA mode 2) that you want to convert.
-
Select IDE (DMA mode 2) as the source unit and SCSI (Fast Ultra Wide) as the target unit.
-
Click the convert button to get the equivalent value in SCSI (Fast Ultra Wide).
-
Review the result and use it for comparing or diagnosing legacy data transfer performance.
Key Features
-
Converts data transfer units between IDE (DMA mode 2) and SCSI (Fast Ultra Wide).
-
Browser-based and easy to use with no installation required.
-
Provides quick insight into legacy interface throughput comparisons.
-
Includes example calculations for reference.
Examples
-
Convert 5 IDE (DMA mode 2) to SCSI (Fast Ultra Wide): 5 × 0.415 = 2.075 SCSI (Fast Ultra Wide).
-
Convert 10 IDE (DMA mode 2) to SCSI (Fast Ultra Wide): 10 × 0.415 = 4.15 SCSI (Fast Ultra Wide).
Common Use Cases
-
Configuring or diagnosing legacy PATA/IDE hard drives to use higher throughput DMA modes.
-
Benchmarking or troubleshooting older storage interfaces to understand transfer rates.
-
Connecting and managing internal hard drives or RAID controllers using parallel SCSI.
-
Performing high-throughput backups with legacy SCSI tape libraries or streaming devices.
-
Interfacing storage enclosures and disk arrays in enterprise systems with parallel SCSI.
Tips & Best Practices
-
Use this converter to compare legacy IDE and SCSI transfer performance during system maintenance.
-
Consider hardware setup and cable quality as these affect actual performance despite conversion values.
-
Apply the tool for legacy system integration and storage troubleshooting tasks.
Limitations
-
Conversion rates indicate interface transfer mode capabilities, not exact data throughput.
-
Actual performance can vary due to hardware, cabling, and system configurations.
-
Both units relate to outdated technologies and may not reflect modern data transfer standards.
Frequently Asked Questions
-
What does IDE (DMA mode 2) mean in data transfer?
-
IDE (DMA mode 2) refers to a Parallel ATA data transfer mode that enables an IDE device to move data directly to or from memory with minimal CPU use, offering higher throughput compared to PIO modes.
-
What is SCSI (Fast Ultra Wide) used for?
-
SCSI (Fast Ultra Wide) is a legacy parallel interface used to connect storage devices like hard drives and tape libraries, providing wider data buses and faster signalling for improved data transfer.
-
Why convert from IDE (DMA mode 2) to SCSI (Fast Ultra Wide)?
-
The conversion helps compare data transfer rates between legacy PATA/IDE and SCSI interfaces for diagnosing, upgrading, or benchmarking older enterprise storage systems.
Key Terminology
-
IDE (DMA mode 2)
-
A legacy Parallel ATA data-transfer mode allowing data movement with minimal CPU intervention, enhancing throughput over PIO modes.
-
SCSI (Fast Ultra Wide)
-
A legacy parallel Small Computer System Interface variant featuring a wider data bus and faster signalling for improved sustained throughput.
