What Is This Tool?
This tool converts data transfer measurements from IDE (UDMA-33), a legacy Parallel ATA mode, to SCSI (LVD Ultra160), a parallel SCSI interface standard. It helps compare data transfer speeds between older storage technologies.
How to Use This Tool?
-
Enter the value in IDE (UDMA-33) units you want to convert
-
Select SCSI (LVD Ultra160) as the target unit
-
Click convert to obtain the equivalent value in SCSI (LVD Ultra160)
-
Use the result to compare or assess legacy storage data transfer rates
Key Features
-
Converts IDE (UDMA-33) data transfer values to SCSI (LVD Ultra160) units
-
Based on maximum theoretical burst rates for legacy storage interfaces
-
Supports benchmarking and performance comparison of older hardware
-
Browser-based and easy to use for IT professionals and enthusiasts
Examples
-
5 IDE (UDMA-33) converts to 1.03125 SCSI (LVD Ultra160)
-
10 IDE (UDMA-33) converts to 2.0625 SCSI (LVD Ultra160)
Common Use Cases
-
Benchmarking throughput for legacy PATA hard drives and optical drives
-
Configuring or troubleshooting BIOS and controller transfer modes on older PCs
-
Comparing legacy PATA and SCSI performance when upgrading storage systems
-
Specifying data-transfer rates for internal disk arrays and RAID controllers in legacy servers
-
Assessing legacy storage bus bandwidth during migration or compatibility planning
Tips & Best Practices
-
Verify compatible controllers and cables when working with IDE (UDMA-33) devices
-
Use this conversion to support legacy hardware maintenance and upgrades
-
Remember conversions represent theoretical maximum burst rates, actual performance may vary
-
Combine conversion results with hands-on testing for more accurate performance evaluation
Limitations
-
Conversion uses theoretical maximum burst rates, not reflecting real-world throughput
-
Hardware limitations, protocol overhead, and environment can affect actual data transfer
-
These standards are legacy and have limited relevance for modern devices and interfaces
Frequently Asked Questions
-
What does IDE (UDMA-33) represent in data transfer?
-
IDE (UDMA-33) is a Parallel ATA data transfer mode using DMA with a maximum theoretical burst rate of 33.3 MB/s, commonly used in older hard drives and optical drives.
-
What is SCSI (LVD Ultra160) used for?
-
SCSI (LVD Ultra160) is a parallel SCSI interface providing up to 160 MB/s as a bandwidth metric for storage I/O paths in legacy server environments.
-
Can this converter guarantee actual transfer speeds?
-
No, it converts maximum theoretical burst rates; actual speeds depend on hardware, protocol overhead, and other factors.
