What Is This Tool?
This converter tool allows you to translate data transfer rates from the SCSI (Fast Wide) standard, a fast 16-bit SCSI-2 interface, to IDE (PIO mode 0), a slower CPU-driven ATA timing mode, helping manage legacy storage interface differences.
How to Use This Tool?
-
Enter the numeric value of your data transfer rate in SCSI (Fast Wide).
-
Select SCSI (Fast Wide) as the source unit and IDE (PIO mode 0) as the target unit.
-
Click convert to view the equivalent IDE (PIO mode 0) transfer rate.
Key Features
-
Converts data transfer rates between SCSI (Fast Wide) and IDE (PIO mode 0).
-
Simple, browser-based unit conversion tool.
-
Ideal for legacy hardware compatibility and performance comparisons.
Examples
-
1 SCSI (Fast Wide) transfer rate equals approximately 6.06 IDE (PIO mode 0) transfer rates.
-
5 SCSI (Fast Wide) transfers are equivalent to about 30.303 IDE (PIO mode 0) transfers.
Common Use Cases
-
Connecting legacy server disk drives and RAID controllers for throughput comparison.
-
Diagnosing and recovering data on vintage PCs using IDE PIO mode 0 drives.
-
Comparing or upgrading legacy storage interfaces in older hardware environments.
Tips & Best Practices
-
Ensure accurate input values for precise conversions.
-
Consider hardware-specific factors affecting actual transfer rates.
-
Use this tool primarily for compatibility and legacy system maintenance.
Limitations
-
Actual throughput can vary based on cable quality, device negotiation, and signaling.
-
IDE (PIO mode 0) is much slower, designed for very old hardware compatibility.
-
Not suitable for modern storage devices due to low transfer rates and old protocols.
Frequently Asked Questions
-
What does SCSI (Fast Wide) mean?
-
SCSI (Fast Wide) is a SCSI-2 interface mode combining Fast timing at 10 MHz with a 16-bit data bus, enabling up to 20 MB/s theoretical throughput on a 16-bit single-ended setup.
-
Why is IDE (PIO mode 0) slower than SCSI (Fast Wide)?
-
IDE (PIO mode 0) uses CPU-driven programmed input/output without DMA, resulting in lower maximum transfer speeds suitable for compatibility with older drives.
-
When should I convert between these units?
-
Conversions are useful when comparing throughput or ensuring compatibility between legacy storage devices, especially in diagnostic or upgrade scenarios.
Key Terminology
-
SCSI (Fast Wide)
-
A SCSI-2 interface mode with 10 MHz fast timing and a 16-bit data bus enabling up to 20 MB/s theoretical throughput on single-ended devices.
-
IDE (PIO mode 0)
-
An ATA/IDE programmed input/output mode using CPU-driven data transfers without DMA, resulting in slower transfer rates for old hardware compatibility.
-
Throughput
-
The rate at which data is transferred from one device to another, often measured in megabytes per second.
