What Is This Tool?
This converter helps translate data transfer rates from the SCSI (LVD Ultra160) standard to the IDE (PIO mode 3) mode, facilitating the comparison of legacy storage device speeds and compatibility analysis.
How to Use This Tool?
-
Enter the value representing the data transfer rate in SCSI (LVD Ultra160).
-
Select the units to convert from and to: SCSI (LVD Ultra160) to IDE (PIO mode 3).
-
Click convert to see the equivalent IDE (PIO mode 3) transfer rate.
Key Features
-
Converts data transfer rates between SCSI (LVD Ultra160) and IDE (PIO mode 3).
-
Based on theoretical maximum throughput values for accurate comparisons.
-
Supports legacy hardware performance benchmarking and system planning.
Examples
-
1 SCSI (LVD Ultra160) equals approximately 14.41 IDE (PIO mode 3).
-
5 SCSI (LVD Ultra160) converts to about 72.07 IDE (PIO mode 3).
Common Use Cases
-
Specifying maximum throughput for internal disk arrays and RAID controllers in legacy servers.
-
Comparing data transfer speeds of tape drives and backup systems using parallel SCSI interfaces.
-
Assessing legacy storage bus bandwidth for migration and compatibility planning.
Tips & Best Practices
-
Use this tool to benchmark performance when upgrading or migrating older systems.
-
Consider hardware limitations beyond theoretical speeds in real-world applications.
-
Cross-check compatibility when interfacing embedded systems with legacy storage devices.
Limitations
-
Conversion reflects theoretical maximum throughputs and excludes CPU overhead or bus contention effects.
-
IDE (PIO mode 3) lacks DMA, so actual transfer rates can be lower in practice.
-
Hardware aging and compatibility restrictions may influence real performance beyond the conversion.
Frequently Asked Questions
-
What does SCSI (LVD Ultra160) represent?
-
It is a parallel SCSI interface standard using low voltage differential signalling with a maximum raw throughput of 160 MB/s.
-
What is IDE (PIO mode 3)?
-
IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for Parallel ATA/IDE storage devices with a theoretical max throughput around 11.1 MB/s.
-
Why is it useful to convert between these two standards?
-
Converting helps compare legacy SCSI storage performance to older IDE devices, supporting system compatibility planning and benchmarking.
Key Terminology
-
SCSI (LVD Ultra160)
-
A parallel SCSI interface standard using Low Voltage Differential signalling that provides up to 160 MB/s throughput.
-
IDE (PIO mode 3)
-
A programmed I/O transfer mode for Parallel ATA/IDE devices with CPU-driven data transfers and about 11.1 MB/s maximum throughput.
-
Programmed I/O (PIO)
-
A data transfer method where the CPU controls data exchange, as opposed to Direct Memory Access (DMA).
