Lexar U-Da-Man (UDMA) Card ReaderOkay, so UDMA is not U-Da-MAn but the new Lexar card reader is cool enough looking to make them “the man.” The new UDMA (Ultra Direct Memory Access) is a pop-top design which upon clicking the top cover (say on the Lexar logo) the card reader slots pop up for flash memory access.
Ultra Direct memory access (UDMA and DMA memory) is a feature of modern computers that allow certain hardware subsystems within the computer to access system memory for reading and/or writing independently of the central processing unit. Many hardware systems use DMA including disk drive controllers, graphics cards, network cards, and sound cards. Computers that have DMA channels can transfer data to and from devices with much less CPU overhead than computers without a DMA channel.Meaning the Lexar UDMA card reader has the ability to read and write to your host system without accessing [much] CPU processing power. This is worth noting as I’ve been downloading 200+ pictures which are all about 3MBs each and that can take time, this reader makes multi-tasking while doing the file transfer much easier and more enjoyable. The Lexar UDMA card reader will be available before December 07 with a price point of $45. Source: Lexar and Wikipedia
