What Is This Tool?
This converter allows you to transform data transfer values from IDE (PIO mode 1), a CPU-driven PATA transfer mode, into SCSI (Fast Ultra), a faster parallel SCSI signaling mode. It helps compare or upgrade between legacy and more advanced data transfer technologies.
How to Use This Tool?
-
Enter the data transfer value in IDE (PIO mode 1) units
-
Select IDE (PIO mode 1) as the source unit and SCSI (Fast Ultra) as the target unit
-
Click the convert button to obtain the equivalent SCSI (Fast Ultra) rate
-
Review and use the converted value for analysis or device configuration
Key Features
-
Supports conversion between IDE (PIO mode 1) and SCSI (Fast Ultra) data transfer rates
-
Provides clear conversion based on official transfer mode definitions
-
Ideal for comparing legacy PATA transfers with modern SCSI throughput
-
Browser-based and easy to use without requiring installation
Examples
-
Convert 5 IDE (PIO mode 1) units to SCSI (Fast Ultra) to get 1.3 SCSI (Fast Ultra)
-
Convert 10 IDE (PIO mode 1) units which equals 2.6 SCSI (Fast Ultra)
Common Use Cases
-
Configuring or diagnosing legacy PATA hard drives in vintage or industrial systems
-
Upgrading data transfer modes in servers with RAID arrays to higher throughput SCSI devices
-
Benchmarking data transfer behavior on embedded systems relying on PIO modes
-
Attaching backup tape drives and robotic libraries using SCSI Fast Ultra
-
Connecting high-bandwidth peripherals such as optical jukeboxes or video capture units
Tips & Best Practices
-
Use this tool for comparative assessment between legacy IDE PIO modes and SCSI technology
-
Apply conversions when upgrading or maintaining hardware with mixed data transfer protocols
-
Consider device compatibility and overhead when interpreting converted results
Limitations
-
Conversion reflects theoretical throughput and does not guarantee actual hardware performance
-
IDE (PIO mode 1) exhibits higher CPU load and lower transfer speed compared to SCSI Fast Ultra
-
Actual speeds may differ due to hardware setup, protocol overhead, and device compatibility constraints
Frequently Asked Questions
-
What is IDE (PIO mode 1) used for?
-
IDE (PIO mode 1) is a data transfer mode controlling each cycle by the CPU, used mainly in older PATA devices and legacy hardware environments.
-
Why convert from IDE (PIO mode 1) to SCSI (Fast Ultra)?
-
Converting helps compare and upgrade transfer rates from legacy CPU-driven modes to faster, lower latency SCSI devices suited for modern and legacy peripherals.
-
Does this conversion guarantee exact real-world performance?
-
No, the conversion indicates theoretical throughput differences; actual performance varies based on hardware and protocol factors.
Key Terminology
-
IDE (PIO mode 1)
-
A CPU-driven transfer mode for PATA devices where each data transfer cycle is controlled directly by the host processor.
-
SCSI (Fast Ultra)
-
A parallel SCSI signaling mode with Fast and Ultra extensions designed to increase data throughput and reduce latency.
-
Data Transfer Rate
-
The speed at which data is transmitted between devices, measured here in units representing different hardware protocols.
