The Ultra DMA (Ultra Direct Memory Access, UDMA) modes were the fastest method used to transfer data through the ATA hard disk interface, usually between...

introduced several "Ultra DMA" transfer modes. These initially supported speeds from 16 to 33 MB/s. In later versions, faster Ultra DMA modes were added...

strategies, where speed of execution is critical. Direct market access (DMA), often combined with algorithmic trading is a means of executing trading...

2 GB. CF+ and CompactFlash Revision 4.0 (2006) added support for IDE Ultra DMA Mode 6 for a maximum data transfer rate of 133 MB/s (UDMA 133). CF+ and...

The motherboard also featured two extra HDD ports, one with the HPT366 Ultra DMA/66 adapter fitted on the mainboard itself. This allowed up to eight IDE...

proper "1/2" AGP divider for the 133 MHz FSB clock rate, AGP 4x, and Ultra DMA 100, but the later revisions also directly supported the Tualatin Pentium...

read, results in 15.63 MB/s. The next fastest bus cycle, 32-bit ISA-style DMA write, yields only 6.67 MB/s. Other transfers may be as low as 2 MB/s. y...

all of the machine's core features into two chips, and added AGP and Ultra DMA support. The iBook was the first mainstream computer designed and sold...

originally 40-conductor, but later higher speed requirements led to an "ultra DMA" (UDMA) mode using an 80-conductor cable with additional wires to reduce...

requirements for data transfer to and from the hard drive led to an "ultra DMA" mode, known as UDMA. Progressively swifter versions of this standard...
