What Is This Tool?
This converter helps translate data transfer speeds from IDE (PIO mode 3), a CPU-driven ATA storage transfer mode, to SCSI (Fast Ultra), a parallel SCSI mode designed for higher throughput and lower latency. It's useful for comparing data rates between legacy and more advanced storage technologies.
How to Use This Tool?

Frequently Asked Questions
-
What does IDE (PIO mode 3) mean?
-
IDE (PIO mode 3) is a CPU-driven transfer mode for ATA/IDE devices with a maximum theoretical throughput near 11.1 megabytes per second.
-
What is SCSI (Fast Ultra)?
-
SCSI (Fast Ultra) combines Fast and Ultra SCSI standards to increase data transfer throughput and reduce latency while maintaining compatibility with the SCSI command set.
-
Why convert between IDE (PIO mode 3) and SCSI (Fast Ultra)?
-
Converting helps compare or translate data rates between older ATA devices and higher-performance SCSI systems, useful in hardware upgrades or compatibility assessments.
Key Terminology
-
IDE (PIO mode 3)
-
A programmed I/O transfer mode for ATA/IDE devices that is driven by the CPU and has a maximum transfer rate of about 11.1 MB/s.
-
SCSI (Fast Ultra)
-
A parallel SCSI signalling mode combining Fast and Ultra standards to enhance throughput and reduce latency with SCSI command compatibility.
-
Data Transfer Rate
-
The speed at which data is transmitted from one device to another, often measured in megabytes per second (MB/s).
