What Is This Tool?
This converter enables you to translate data transfer rates from IDE (DMA mode 0), a low-speed ATA transfer mode, into SCSI (Fast), a legacy parallel SCSI bus standard. It supports understanding and managing legacy hardware performance by converting between these two data transfer units.
How to Use This Tool?
-
Enter the amount of data transfer speed in IDE (DMA mode 0)
-
Select IDE (DMA mode 0) as the source unit and SCSI (Fast) as the target unit
-
Click convert to get the equivalent data transfer value in SCSI (Fast)
Key Features
-
Converts data transfer speeds from IDE (DMA mode 0) to SCSI (Fast)
-
Supports legacy parallel ATA and SCSI device comparison
-
Browser-based and easy to use without installation
-
Provides straightforward numeric conversion based on defined rates
Examples
-
5 IDE (DMA mode 0) equals 2.1 SCSI (Fast)
-
10 IDE (DMA mode 0) equals 4.2 SCSI (Fast)
Common Use Cases
-
Comparing legacy parallel ATA drive speeds with older SCSI device rates
-
Managing or integrating legacy IT hardware systems in industrial or embedded environments
-
Assisting OS or BIOS device drivers in recognizing and configuring legacy DMA modes
-
Supporting early RAID or disk-array systems with parallel SCSI interfaces
Tips & Best Practices
-
Understand that both units represent legacy transfer standards used mainly in older equipment
-
Use the conversion to facilitate interoperability analysis between ATA and SCSI buses
-
Verify device-specific performance as real-world speeds may vary from nominal values
Limitations
-
Conversion applies only to legacy hardware with slower transfer speeds than modern interfaces
-
Performance may fluctuate due to device-specific factors beyond nominal conversion rates
-
Does not address newer serial or high-speed data transfer standards
Frequently Asked Questions
-
What is IDE (DMA mode 0)?
-
IDE (DMA mode 0) is the lowest speed direct memory access transfer mode for ATA/IDE devices, enabling data transfer without CPU-driven programmed I/O.
-
What does SCSI (Fast) refer to?
-
SCSI (Fast) is a parallel SCSI bus extension that increases transfer rates over original SCSI by faster timing, typically around 10 MB/s.
-
Why convert between IDE (DMA mode 0) and SCSI (Fast)?
-
Conversion helps compare and translate legacy data transfer rates when integrating or managing older parallel ATA and SCSI devices.
Key Terminology
-
IDE (DMA mode 0)
-
The first and slowest direct memory access mode for ATA/IDE devices, moving data directly into system memory without CPU intervention.
-
SCSI (Fast)
-
A legacy parallel SCSI bus standard that increases data transfer speed typically to about 10 MB/s using faster timing and signaling.
-
Direct Memory Access (DMA)
-
A technique allowing devices to transfer data directly to memory without using the CPU, reducing overhead during data transfers.
