Examples
-
Convert 2 SCSI (Fast Ultra Wide) units to IDE (UDMA mode 2): 2 × 1.2121212121 = 2.4242424242 IDE (UDMA mode 2).
-
Convert 5 SCSI (Fast Ultra Wide) units to IDE (UDMA mode 2): 5 × 1.2121212121 = 6.0606060605 IDE (UDMA mode 2).
Common Use Cases
-
Translating legacy parallel SCSI speed metrics to PATA/IDE equivalents for easier comparison.
-
Supporting maintenance and upgrades in environments where SCSI and IDE storage devices coexist.
-
Troubleshooting data transfer issues by understanding device interface performance capacities.
-

Tips & Best Practices
-
Verify hardware conditions and controller compatibility when evaluating transfer rates.
-
Use this conversion as a reference for theoretical maximum throughput comparisons.
-
Consider cable quality and system overhead impact when interpreting actual transfer speeds.
-
Apply conversions within legacy system maintenance and troubleshooting scenarios only.
Limitations
-
Conversion reflects theoretical maximum transfer rates, not guaranteed real-world speeds.
-
Practical use is limited to legacy hardware supporting these specific data transfer modes.
-
Incompatibility with modern systems restricts use mostly to specialized environments.
-
Actual throughput varies due to hardware state, drivers, and system conditions.
Frequently Asked Questions
-
What does SCSI (Fast Ultra Wide) represent?
-
It is a legacy parallel Small Computer System Interface mode combining a wider data bus with faster signalling to provide higher data transfer throughput than earlier narrow SCSI types.
-
What is IDE (UDMA mode 2)?
-
IDE (UDMA mode 2) is an Ultra DMA mode for Parallel ATA interfaces offering up to about 33.3 megabytes per second in data transfers on legacy PATA/IDE systems.
-
Why would I convert between these units?
-
Converting helps translate performance metrics between legacy SCSI and PATA/IDE devices, useful for system comparisons, compatibility checks, and troubleshooting in older storage environments.
-
Is this conversion accurate for all real-world cases?
-
No, the conversion is based on maximum theoretical rates; actual throughput depends greatly on hardware condition, cabling, and system factors.
Key Terminology
-
SCSI (Fast Ultra Wide)
-
A legacy parallel interface mode that uses a wider data bus and faster signalling for higher transfer throughput in older storage systems.
-
IDE (UDMA mode 2)
-
An Ultra DMA transfer mode for PATA/IDE interfaces providing about 33.3 MB/s data transfer used in legacy PC drives.
-
Data Transfer Rate
-
The amount of data moved from one location to another in a given time, often measured in megabytes per second.
