What Is This Tool?
This tool helps convert data transfer metrics from IDE (PIO mode 4), a legacy CPU-driven ATA timing mode, to SCSI (LVD Ultra160), a higher-speed parallel SCSI interface standard. It facilitates evaluation and benchmarking by translating throughput measurements between these distinct storage bus protocols.
How to Use This Tool?
-
Enter the value in IDE (PIO mode 4) units to be converted
-
Select IDE (PIO mode 4) as the source unit and SCSI (LVD Ultra160) as the target unit
-
Submit to view the equivalent data transfer rate in SCSI (LVD Ultra160) units
Key Features
-
Converts theoretical maximum data transfer rates from IDE (PIO mode 4) to SCSI (LVD Ultra160)
-
Supports analysis of legacy and modern storage interface throughput
-
Browser-based and easy to use for quick conversions
-
Useful for IT diagnostics, system upgrades, and storage compatibility checks
Examples
-
1 IDE (PIO mode 4) equals 0.10375 SCSI (LVD Ultra160)
-
10 IDE (PIO mode 4) equals 1.0375 SCSI (LVD Ultra160)
Common Use Cases
-
Benchmarking and comparing data transfer speeds between older IDE and newer SCSI storage devices
-
Planning system upgrades or migrations involving legacy and modern storage interfaces
-
Diagnosing and configuring legacy PC or embedded system storage settings
-
Assessing throughput for internal disk arrays and RAID controllers using parallel SCSI
Tips & Best Practices
-
Use the tool to express older ATA throughput in terms of modern SCSI standards for clearer comparison
-
Apply conversions during system compatibility evaluations to ensure performance expectations
-
Recognize that conversion reflects theoretical throughput, not actual runtime data transfer speeds
Limitations
-
Conversion is based on theoretical maximum throughput ratios, not observed speeds
-
Units describe protocol timing and bandwidth, not physical storage capacity
-
Actual data rates may differ depending on hardware, software, and operational conditions
Frequently Asked Questions
