(NCQ), and Port Multiplier capability. Performance doubts about SATA are put to rest not only with a 3Gb/second access rate and the Port Multiplier function, but also with Native Command Queuing. Commonly seen with Fibre Channel and SCSI, NCQ uses an algorithm to determine the most efficient...
NCQ:原生指令排序(Native Command Queuing) 一般我们的硬盘使用的文件格式为FAT32或者NTFS,这两种文件格式随着使用时间久了之后,会出现不同大小的碎片文件,造成文件的不连贯,这样硬盘的磁头就需要来回寻道来读写所需要的文件,造成一定的性能下降。要改善这类性能下降有几种方法,最简单的就是进行磁盘碎片整理,另一种就...
Native command queuing (NCQ) is a technology enabling SATA hard drives to accept more than one command at a time by optimizing the order in which read and write commands are executed. This increases the performance of the drive by limiting the number of drive head movements when multiple read...
