Frequently Asked Questions
-
What does IDE (DMA mode 2) mean?
-
It is a Multiword DMA mode 2 transfer method for IDE devices, enabling data movement with less CPU usage and higher throughput than PIO modes, used in legacy PATA/IDE interfaces.
-
What is SCSI (Fast)?
-
Fast SCSI is an enhanced parallel SCSI bus standard that roughly doubles the original SCSI throughput to around 10 MB/s, used in older storage and peripheral devices.
-
Why convert between IDE (DMA mode 2) and SCSI (Fast)?
-
Conversion allows users to compare data transfer rates and performance across legacy storage interfaces, aiding diagnostics, benchmarking, and hardware configuration.
Key Terminology
-
IDE (DMA mode 2)
-
A Multiword DMA mode for IDE devices allowing efficient data transfer with less CPU usage in legacy PATA interfaces.
-
SCSI (Fast)
-
A parallel SCSI bus extension that increases the original SCSI transfer rate by using faster timing to move data between host and devices.
-
Data Transfer Rate
-
The speed at which data moves from one device or interface to another, typically measured in megabytes per second (MB/s).
