What does IDE (PIO mode 0) mean in data transfer?

It is a CPU-driven ATA timing mode with very low maximum throughput, used for interfacing with older storage devices without DMA support.

What is special about SCSI (LVD Ultra80)?

It uses Low Voltage Differential signaling on a 16-bit bus with synchronous transfers at 40 MHz, providing higher bandwidth and better noise immunity than single-ended SCSI.

Can I directly connect IDE (PIO mode 0) and SCSI (LVD Ultra80) devices?

Due to differences in bus and signaling technologies, direct interoperability is limited, and adapters or interfaces are typically required.
