What Is This Tool?
This converter tool allows users to translate data transfer speeds from IDE (DMA mode 0), a low-speed direct memory access mode for ATA/IDE devices, into equivalent speeds in SCSI (LVD Ultra160), a parallel SCSI interface known for higher bandwidth. It's designed to assist in understanding and comparing legacy storage interfaces.
How to Use This Tool?
-
Enter the number of units in IDE (DMA mode 0) that you want to convert
-
Select IDE (DMA mode 0) as the input unit and SCSI (LVD Ultra160) as the output unit
-
Click the convert button to see the equivalent value in SCSI (LVD Ultra160)
-
Use the result to compare or assess legacy storage device performance
Key Features
-
Converts from IDE (DMA mode 0) to SCSI (LVD Ultra160) using a defined rate
-
Provides clear, easy-to-understand conversion based on standardized specifications
-
Supports comparisons of legacy storage device throughput and interface bandwidth
-
Browser-based and user-friendly interface for quick conversions
Examples
-
10 IDE (DMA mode 0) equals 0.2625 SCSI (LVD Ultra160)
-
50 IDE (DMA mode 0) equals 1.3125 SCSI (LVD Ultra160)
Common Use Cases
-
Evaluating legacy PATA hard drive transfer speeds in older computer systems
-
Comparing internal disk array throughput in legacy servers using SCSI interfaces
-
Planning migration and compatibility assessments involving legacy storage buses
-
Assessing bandwidth for tape drives and backup solutions utilizing parallel SCSI
Tips & Best Practices
-
Use the tool primarily for legacy or historical hardware performance comparisons
-
Verify device-specific capabilities beyond theoretical maximum rates
-
Consider system overhead and signal quality separately from conversion results
-
Apply conversion results in conjunction with other hardware compatibility checks
Limitations
-
Reflects only maximum theoretical data transfer rates without real-world adjustments
-
Does not account for actual device performance or environmental factors
-
Conversion applies to legacy standards that may no longer be relevant for modern devices
Frequently Asked Questions
-
What does IDE (DMA mode 0) mean?
-
IDE (DMA mode 0) is the lowest-speed direct memory access transfer mode for ATA/IDE devices, used to move data blocks directly to system memory with minimal CPU involvement.
-
What is SCSI (LVD Ultra160)?
-
SCSI (LVD Ultra160) is a parallel SCSI interface standard that uses Low Voltage Differential signalling to provide data transfer speeds up to 160 MB/s between host adapters and SCSI devices.
-
Why convert between IDE (DMA mode 0) and SCSI (LVD Ultra160)?
-
Converting helps compare legacy ATA/IDE device speeds to SCSI throughput for planning upgrades, compatibility checks, and performance evaluations in legacy systems.
Key Terminology
