Tips & Best Practices
-
Use the conversion to facilitate performance comparisons in legacy environments
-
Consider hardware and signal conditions when interpreting results
-
Apply conversions for diagnosing or upgrading storage hardware
-
Remember the conversion reflects ideal theoretical rates, not actual speeds
Limitations
-
Conversion is based on theoretical maximum throughput rates
-
Actual data transfer speeds vary due to hardware and cable quality
-
Signal interference and device negotiation can affect real-world results
Frequently Asked Questions
-
What does IDE (PIO mode 1) mean?
-
It is a CPU-controlled data transfer mode for PATA devices, offering low-to-moderate throughput with higher CPU overhead compared to other modes.
-
What is SCSI (Fast Wide)?
-
A SCSI-2 interface combining 10 MHz Fast timing with a 16-bit data bus for higher theoretical transfer speeds than original 8-bit SCSI.
-
Why convert IDE (PIO mode 1) to SCSI (Fast Wide)?
-
To compare or translate data transfer rates for performance benchmarking and compatibility assessments in legacy systems.
Key Terminology
-
IDE (PIO mode 1)
-
A CPU-controlled Programmed Input/Output transfer mode for PATA devices with moderate throughput and higher CPU usage.
-
SCSI (Fast Wide)
-
A SCSI-2 mode using Fast timing at 10 MHz and a 16-bit data bus to increase transfer speeds over original SCSI.
-
Data Transfer Rate
-
The speed at which data is moved from one device to another, often measured in megabytes per second.
