What does IDE (UDMA-33) represent?

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

Why convert IDE (UDMA-33) to GB/s?

Converting IDE (UDMA-33) to gigabytes per second allows comparing legacy data transfer rates with modern storage and memory speeds using a common unit.

Does the gigabyte in GB/s always mean the same size?

No, GB/s can refer to decimal gigabytes (10^9 bytes) or sometimes binary gigabytes (gibibytes), so it is important to clarify which is used when interpreting data rates.
