What is IDE (UDMA-33)?

IDE (UDMA-33), also known as ATA/33 or Ultra DMA mode 4, is a legacy Parallel ATA data-transfer mode with a theoretical maximum burst rate of 33.3 MB/s, used on older hard drives and optical drives.

Is H11 a standard unit for data transfer?

No, H11 is not a recognized or standard data transfer unit. It is a non-standard unit not used in scientific or engineering contexts.

Why would I convert IDE (UDMA-33) to H11?

Users may convert IDE (UDMA-33) to H11 to relate legacy PATA data transfer speeds to a unit format that can be compared or mapped to modern data transfer representations, even though H11 itself is non-standard.
