What Is This Tool?
This converter allows users to translate data transfer rates between IDE (PIO mode 4), an older CPU-driven timing mode for ATA devices, and SCSI (Fast Ultra), a more advanced parallel signalling standard. It helps in assessing and comparing storage performance across legacy and modern technologies.
How to Use This Tool?
-
Enter the data transfer value in IDE (PIO mode 4) units
-
Select SCSI (Fast Ultra) as the target conversion unit
-
Trigger the conversion to see the equivalent rate in SCSI (Fast Ultra)
-
Use results to compare device performance or assess upgrade options

-
Converts data transfer rates from IDE (PIO mode 4) to SCSI (Fast Ultra)
-
Supports performance comparison between legacy and current storage modes
-
Browser-based and easy to use with straightforward inputs and outputs
-
Provides common use cases and contextual information for conversions
Examples
-
1 IDE (PIO mode 4) equals 0.83 SCSI (Fast Ultra)
-
10 IDE (PIO mode 4) convert to 8.3 SCSI (Fast Ultra)
Common Use Cases
-
Configuring or diagnosing legacy IDE/ATA drives and BIOS settings

Actual speeds vary by device status, system design, and workload
-
IDE (PIO mode 4) is slower and less efficient than SCSI Fast Ultra
-
Hardware compatibility may require additional considerations apart from rate conversion
Frequently Asked Questions
-
What does IDE (PIO mode 4) mean in data transfer?
-
IDE (PIO mode 4) is a CPU-controlled timing mode for ATA/IDE devices involving handshaking and timing protocols for data transfer.
-
What is SCSI (Fast Ultra)?
-
SCSI (Fast Ultra) is a parallel signalling mode that combines Fast and Ultra SCSI standards to improve throughput and reduce latency.
