记得当存储卡厂商高调公布UDMA、300×等高端规格之初,并没有完全相对的产品应用,传输端也存在瓶颈。随着支持UDMA技术的Canon EOS-1Ds MarkⅢ、Nikon D3等数码单反的上市和专用火线读卡器的推出,Lexar Professional UDMA 300×CF这类的产品完成了从指标神话到应用王者的转变。UDMA(Ultra DMA)源自硬盘技术,可大幅提升数据的读取速度。按照300×的规格,理论传输速率将高达45MB/s,目前
Remember when high-profile memory card makers announced UDMA, 300 × and other high-end specifications at the beginning, there is no complete relative product applications, there are bottlenecks on the transmission side. With the introduction of digital SLRs such as the Canon EOS-1Ds Mark III and Nikon D3 supporting UDMA technology and the introduction of a dedicated FireWire card reader, products like Lexar Professional UDMA 300 × CF have made the transition from target myths to application kings. UDMA (Ultra DMA) comes from hard disk technology, can greatly improve the data read speed. According to the 300 × specification, the theoretical transfer rate will be as high as 45MB / s, at the moment
