The Word DMA (WDMA) interface is a method for transferring data between a computer (through an Advanced Technology Attachment (ATA) controller) and an ATA device; it was the fastest method until Ultra Direct Memory Access (UDMA) was implemented. Single/Multiword DMA took over from programmed input/output (PIO) as the choice of interface between ATA devices and the computer.
