What does IDE (PIO mode 2) represent?

It is a legacy ATA/IDE interface timing specification defining CPU-driven data transfer timing and performance for older IDE devices.

SCSI (Fast) is an extension to the parallel SCSI bus that doubles the transfer rate of the original SCSI interface, commonly used in older servers and storage arrays.

Why would I need to convert between these units?

To compare or interpret data transfer rates between legacy IDE and SCSI devices, especially for diagnostics, compatibility checks, or system upgrades in vintage environments.
