Frequently Asked Questions
-
What does IDE (DMA mode 1) refer to?
-
IDE (DMA mode 1) is a Direct Memory Access mode designed for IDE/ATA storage devices to transfer data directly with minimal CPU involvement, following specific timing constraints for moderate-speed transfers.
-
Why convert IDE (DMA mode 1) rates to USB?
-
Converting IDE (DMA mode 1) to USB units facilitates comparison between older IDE hardware speeds and modern USB data transfer rates for compatibility checks and performance evaluation.
-
Can the conversion rate between IDE (DMA mode 1) and USB be exact?
-
No, the conversion provides an approximate rate since actual transfer speeds depend on various factors like device specifics, protocol overhead, and USB generation.
