What is IDE (UDMA mode 4)?

IDE (UDMA mode 4), also known as Ultra DMA/66 or ATA-4, is a Parallel ATA transfer mode that enables data transfers up to around 66.7 megabytes per second using an 80-conductor IDE cable.

Why convert IDE (UDMA mode 4) speeds to kilobit/second?

Converting IDE speeds to kilobit/second helps compare legacy storage device transfer rates with standard network communication speeds measured in bits per second.

Does this converter reflect real-world data transfer speeds?

No, this conversion uses theoretical maximums and does not account for overhead, signal limitations, or real operational conditions.
