What Is This Tool?
This converter allows users to translate data transfer rates from Fast SCSI, a legacy parallel SCSI bus standard, to IDE with Ultra DMA mode 2, a Parallel ATA transfer mode. It helps compare performance and compatibility between older storage technologies.
How to Use This Tool?
-
Enter the data transfer value measured in SCSI (Fast).
-
Select 'SCSI (Fast)' as the source unit and 'IDE (UDMA mode 2)' as the target unit.
-
Click convert to see the equivalent value in IDE (UDMA mode 2).
Key Features
-
Simple and browser-based conversion between SCSI (Fast) and IDE (UDMA mode 2).
-
Supports legacy data transfer units used in older computer hardware.
-
Shows equivalent values to assist in benchmarking and troubleshooting.
-
Includes clear definitions and practical use cases for each unit.
Examples
-
1 SCSI (Fast) is approximately 0.303 IDE (UDMA mode 2).
-
10 SCSI (Fast) converts to about 3.03 IDE (UDMA mode 2).
Common Use Cases
-
Comparing data transfer speeds between parallel SCSI and PATA/IDE storage systems.
-
Benchmarking legacy storage device performance in older servers or workstations.
-
Troubleshooting or restoring vintage computer hardware environments.
-
Assessing compatibility for legacy RAID or disk-array systems using SCSI or IDE.
Tips & Best Practices
-
Use this converter primarily for legacy system evaluations and comparisons.
-
Cross-check conversion results with actual device specifications when possible.
-
Consider that physical bus and hardware conditions may affect real throughput beyond theoretical rates.
-
Apply this tool when diagnosing or upgrading systems that involve older SCSI or IDE interfaces.
Limitations
-
Only applies to legacy technologies with fixed maximum transfer rates.
-
Does not account for dynamic hardware or protocol overhead affecting real throughput.
-
Modern serial interfaces surpass these transfer capabilities significantly, limiting relevance for contemporary systems.
Frequently Asked Questions
-
What does Fast SCSI represent in terms of data transfer?
-
Fast SCSI is a parallel SCSI bus extension that doubles classic 8-bit SCSI throughput to about 10 MB/s using faster timing and signaling.
-
What is IDE (UDMA mode 2) commonly known as?
-
IDE (UDMA mode 2) is also called ATA/33 and provides a maximum theoretical transfer rate of approximately 33.3 MB/s for PATA interfaces.
-
Why convert from SCSI (Fast) to IDE (UDMA mode 2)?
-
Converting helps compare legacy data transfer rates for benchmarking, compatibility assessments, and troubleshooting between parallel SCSI and PATA/IDE systems.
Key Terminology
-
Fast SCSI
-
A legacy parallel SCSI bus extension improving original SCSI transfer rates to about 10 MB/s by using faster signaling.
-
IDE (UDMA mode 2)
-
An Ultra DMA transfer mode for Parallel ATA interfaces providing up to roughly 33.3 MB/s theoretical synchronous data transfers.
-
Parallel ATA (PATA)
-
An older interface standard for connecting storage devices in PCs, utilizing parallel data transmission.
