What Is This Tool?
This tool converts data transfer rates from SCSI (Ultra-2), a high-performance parallel SCSI interface, to IDE (UDMA-33), a legacy Parallel ATA transfer mode. It helps compare and analyze data transfer speeds between enterprise-grade and legacy storage technologies.
How to Use This Tool?
-
Enter a value in the SCSI (Ultra-2) data transfer rate field
-
Select SCSI (Ultra-2) as the source unit and IDE (UDMA-33) as the target unit
-
Click the convert button to see the equivalent IDE (UDMA-33) rate
-
Use the results to compare performance or assist in hardware configuration

Frequently Asked Questions
-
What does the conversion rate from SCSI (Ultra-2) to IDE (UDMA-33) represent?
-
It represents the theoretical data transfer equivalence, showing how many IDE (UDMA-33) units match one SCSI (Ultra-2) transfer rate.
-
Can I use IDE (UDMA-33) on modern computers?
-
IDE (UDMA-33) is a legacy standard and might not be supported by most modern systems.
-
Why might actual data transfer speed differ from this conversion?
-
Real-world speed depends on factors like hardware performance, cable quality, controller compatibility, and protocol overhead.
Key Terminology
-
SCSI (Ultra-2)
-
A parallel SCSI standard using Low Voltage Differential signaling for high data transfer and longer cable support.
-
IDE (UDMA-33)
-
A Parallel ATA data-transfer mode for legacy hard drives and optical drives with a burst transfer rate near 33 MB/s.
-
DMA (Direct Memory Access)
-
A method allowing direct data transfer between memory and devices without CPU intervention.
