ATA133 and Ultra DMA mode 6 are the same thing.It a transfer protocol with a theoretical transfer rate of 133 MB/s.(basically how fast your data gets from the hard drive to the RAM.)
I'm new here but I expect the reason you didn't get an answer sooner is because it is something that can easily be answered in great detail with any search engine.Good luck.

DMA: Dynamic Memory Access

it means that as long as the CPU doesn't access the I/O port at the same time,
the device can store into the I/O port without interferring with the CPU.
see this

An alternative to DMA is the Programmed Input/Output (PIO) interface in which all data transmitted between devices goes through the processor. A newer protocol for the ATA/IDE interface is Ultra DMA, which provides a burst data transfer rate up to 33 MB (megabytes) per second. Hard drives that come with Ultra DMA/33 also support PIO modes 1, 3, and 4, and multiword DMA mode 2 (at 16.6 megabytes per second).
