What Is This Tool?
This tool allows you to convert data transfer rates between IDE (UDMA mode 4), a Parallel ATA mode used in older PCs, and SCSI (LVD Ultra80), a Low Voltage Differential SCSI interface common in legacy server storage systems.
How to Use This Tool?
-
Enter the numeric value representing the data transfer rate in IDE (UDMA mode 4) units.
-
Select IDE (UDMA mode 4) as the input unit and SCSI (LVD Ultra80) as the output unit.
-
Click the convert button to get the equivalent value in SCSI (LVD Ultra80).
Key Features
-
Converts data transfer units between IDE (UDMA mode 4) and SCSI (LVD Ultra80)
-
Supports comparisons of legacy data transfer protocols and bandwidth
-
Browser-based, easy-to-use interface for quick results
-
Includes conversion formulas and example calculations
Examples
-
1 IDE (UDMA mode 4) equals 0.825 SCSI (LVD Ultra80)
-
10 IDE (UDMA mode 4) equals 8.25 SCSI (LVD Ultra80)
Common Use Cases
-
Comparing data transfer rates between older PATA/IDE devices and legacy SCSI hardware
-
Benchmarking and troubleshooting storage performance in environments with mixed hardware
-
Planning and managing legacy computer storage systems and enterprise servers
Tips & Best Practices
-
Use high-quality cables for reliable data transfer performance when working with legacy hardware.
-
Consider protocol differences beyond bandwidth when interpreting converted values.
-
Verify hardware compatibility especially when dealing with legacy server and storage devices.
Limitations
-
Conversion values reflect theoretical maximum throughput and do not factor in real-world overhead.
-
Signal quality and cable condition can affect actual transfer speeds.
-
Differences in protocols and transfer efficiency are not accounted for in the conversion rate.
Frequently Asked Questions
-
What does IDE (UDMA mode 4) represent?
-
IDE (UDMA mode 4), also known as Ultra DMA/66, is a Parallel ATA transfer mode used in older PCs to move data blocks at maximum theoretical rates near 66.7 megabytes per second.
-
What is SCSI (LVD Ultra80)?
-
SCSI (LVD Ultra80) is a Low Voltage Differential SCSI interface variant offering up to 80 megabytes per second bandwidth with improved noise immunity and cable length compared to single-ended SCSI.
-
Why would I need to convert between these units?
-
Converting between IDE (UDMA mode 4) and SCSI (LVD Ultra80) helps users compare and translate transfer rates for benchmarking, troubleshooting, and managing legacy storage systems with different interface standards.
Key Terminology
-
IDE (UDMA mode 4)
-
A Parallel ATA transfer mode using Ultra DMA protocol with up to about 66.7 MB/s throughput, requiring an 80-conductor IDE cable.
-
SCSI (LVD Ultra80)
-
A Low Voltage Differential variant of Ultra2 SCSI with up to 80 MB/s raw bandwidth over a 16-bit bus at 40 MHz.
-
Conversion Rate
-
A multiplier used to translate data transfer values from IDE (UDMA mode 4) units to equivalent SCSI (LVD Ultra80) units.
