What Is This Tool?
This unit converter helps translate data transfer rates between IDE (UDMA-66), a Parallel ATA transfer mode for legacy storage devices, and SCSI (Ultra-3), a parallel SCSI interface standard used in storage subsystems. It allows users to compare and evaluate transfer capabilities between these legacy systems.
How to Use This Tool?
-
Enter the value you want to convert from IDE (UDMA-66)
-
Select IDE (UDMA-66) as the input unit and SCSI (Ultra-3) as the output unit
-
Click the convert button to see the equivalent SCSI (Ultra-3) data transfer rate
-
Use the results to compare or benchmark legacy storage subsystem performance
Key Features
-
Converts data transfer rates between IDE (UDMA-66) and SCSI (Ultra-3)
-
Supports legacy storage interface units used in IT infrastructure and server maintenance
-
Browser-based and easy to use with simple input and output fields
-
Facilitates performance benchmarking and compatibility checking between interface types
-
Provides direct conversion based on the theoretical maximum data rates
Examples
-
1 IDE (UDMA-66) equals 0.4125 SCSI (Ultra-3)
-
10 IDE (UDMA-66) converts to 4.125 SCSI (Ultra-3)
Common Use Cases
-
Specifying or verifying the maximum throughput of older PATA (IDE) hard drives
-
Configuring transfer modes in BIOS or legacy systems for IDE drives
-
Connecting enterprise hard drives and RAID controllers via SCSI in legacy servers
-
Benchmarking parallel SCSI interface performance in storage subsystems
-
Comparing data rates for system upgrades or diagnostics involving IDE and SCSI equipment
-
Supporting data center backup solutions using tape drives and automated libraries
Tips & Best Practices
-
Ensure you understand the legacy nature of these interfaces before converting
-
Use the conversion rates for theoretical comparison only, not real-world throughput
-
Consult hardware documentation when configuring device transfer modes
-
Consider the context of your storage environment when interpreting results
Limitations
-
Does not account for actual throughput affected by hardware or protocol overhead
-
Only applies to the theoretical maximum data rates of legacy interfaces
-
Not suitable for modern storage technologies with newer transfer standards
Frequently Asked Questions
-
What does IDE (UDMA-66) represent in data transfer?
-
IDE (UDMA-66) is a Parallel ATA transfer mode specifying a maximum raw data rate of 66.7 megabytes per second for legacy PATA devices.
-
What is SCSI (Ultra-3) used for?
-
SCSI (Ultra-3) is a version of the Small Computer System Interface standard used mainly in legacy storage subsystems such as enterprise hard drives and RAID controllers.
-
Can this tool be used for modern storage devices?
-
No, this conversion only applies to legacy IDE and SCSI interfaces and does not cover modern storage transfer standards.
