[kenneth_18]

what is ultra dma

 

[someone19]

Its describing the method used to transfer information between the hard drive and the system. The interface is just that, the interface, but ultra DMA describes the protocol used to exchange information.

DMA stands for Direct Memory Access.

UltraDMA is an outdated data transfer protocol used by hard drives and optical drives. The protocol was used on the old PATA interface. It was replaced by SATA.
