What does IDE (DMA mode 1) represent?

IDE (DMA mode 1) is a moderate-speed Direct Memory Access transfer mode for the IDE/ATA interface that reduces CPU involvement by transferring data directly between the device and system memory.

What is SCSI (LVD Ultra80)?

SCSI (LVD Ultra80) is a Low Voltage Differential SCSI interface providing up to 80 MB/s bandwidth on a 16-bit wide bus, offering improved noise immunity and cable length over single-ended SCSI.

Why convert from IDE (DMA mode 1) to SCSI (LVD Ultra80)?

Converting helps compare transfer speeds between moderate-speed legacy IDE and faster enterprise SCSI interfaces, useful for troubleshooting and performance optimization in mixed hardware environments.
