What is IDE (UDMA-33)?

IDE (UDMA-33), also called ATA/33 or Ultra DMA mode 4, is an older Parallel ATA data-transfer mode for IDE/ATA drives with a theoretical burst rate of 33.3 MB/s.

Why convert IDE (UDMA-33) to megabit per second?

Converting to megabit per second allows comparison of legacy PATA data rates with modern digital bandwidth units used in networking and telecommunications.

Can I rely on the converted values as actual sustained speeds?

No, the IDE (UDMA-33) rates represent maximum burst speeds and may not reflect real-world sustained transfer rates.
