Combine with other diagnostic tools for thorough performance evaluation
Limitations
-
Conversion applies only to legacy IDE (DMA mode 1) and SCSI (Fast Ultra Wide) units
-
Transfer speeds may vary due to hardware conditions and controller differences
-
Neither unit reflects modern data transfer technologies or speeds
-
Theoretical conversions might not match real-world performance exactly
Frequently Asked Questions
-
What does IDE (DMA mode 1) represent?
-
It is a direct memory access transfer mode used in IDE/ATA storage interfaces, allowing data movement with low CPU involvement under specific timing constraints.
-
What is SCSI (Fast Ultra Wide)?
-
A legacy SCSI interface variant featuring a wider parallel data bus and faster signalling for higher throughput compared to earlier narrow SCSI modes.
-
Why convert between IDE (DMA mode 1) and SCSI (Fast Ultra Wide)?
-
To compare and translate data transfer rates between older IDE/ATA and faster parallel SCSI storage systems for tuning, compatibility, or system integration.
Key Terminology
-
IDE (DMA mode 1)
-
A direct memory access mode in IDE/ATA interfaces allowing moderate-speed transfers with minimal CPU involvement based on specific timing protocols.
-
SCSI (Fast Ultra Wide)
-
A parallel SCSI interface variant combining a wider data bus and faster signalling to achieve higher sustained data throughput than earlier narrow SCSI versions.
-
Data Transfer
-
The process of moving data from one device or memory location to another, measured here in legacy interface units.
