Ultra-DMA has many names, but we'll just call it UDMA in here. UDMA is a more advanced technology which provides for even faster throughput, up to 33.3 MB/s in UDMA mode 2 and 66.7 MB/s in UDMA mode 4, twice to four times that of EIDE, for much lower prices than SCSI.
UDMA模式详解-CSDN博客
2012年9月26日 · Ultra DMA硬盘 为IDE硬盘的提高型,也作Ultra ATA硬盘,简称UDMA硬盘,分为UDMA/33和UDMA/66两种,UDMA/33 的瞬间传输速率可达33.3MBPS,另一优点在于比普通IDE硬盘CPU读写占有率降低50%左右,即读写时很少需要CPU控制,在硬盘进行读写的大部分时间内CPU可去做其它可做的事,从而使系统速度明显提高。 UDMA/33的信号线和普通IDE硬盘相同,故一般微机也可安装,但如果没有新型的支持UDMA技术的主控芯片组和主板的支持,只能 …
Ultra Direct Memory Access - GeeksforGeeks
2024年5月28日 · Ultra Direct Memory Access (UDMA) is a protocol used as part of high-speed technology for data transfer from a computer's memory to the hard drive, SSD, or other storage media. In this way, data rates and system performance are greatly maximized by using a direct channel between storage and main memory that works independently from the CPU.
What is UDMA (Ultra Direct Memory Access)? - EComputerTips
Ultra Direct Memory Access, commonly known as UDMA, is a powerful data transfer protocol designed for mass storage devices, particularly those using the ATA interface.
