对磁盘高速存取(提速): RAID将普通硬盘组成一个磁盘阵列，在主机写入数据，RAID控制器把主机要写入的数据分解为多个数据块，然后并行写入磁盘阵列；主机读取数据时，RAID控制器并行读取分散在磁盘阵列中各个硬盘上的数据，把它们重新组合后提供给主机。由于采用并行读写操作，从而提高了存储系统的存取系统的存取速度-High-speed disk access (speed): RAID will be common to form a hard drive disk array, the host write data, RAID host controller to write data to be divided into multiple data blocks, and then write to the disk arrays in parallel the host to read data, RAID controller in parallel disk array read scattered in various hard drive data to regroup after they offered to host. As a result of parallel read and write operations, thereby enhancing the storage system access system access speed
