The addition of a third drive to a simple two-drive,Level One RAID architecture adds to the complexity of the system design.when a third drive is added, the actual usable capacity of the array doubles that of a one-or two-drive array.Thus,a two-drive array using 30 gigabyte drives provides a capacity of 30 gigabytes,while a three-drive array provides a total capacity of 60 gigabytes.
Instead of mirroring a single drive,data is distributed across the three drives.In theory,one third of the three-drive array is in use for data backup,parity,and error-correction data. If one drive fails,data on the remaining two drives would be adequate to keep the system running,and for reconstructing the failed drive.

Answer 1

增加了一个第三驱动为一种简单的two-drive,一级袭击建筑增加了系统的复杂度design.when第三驱动器补充道,实际可用的容量数组的two-drive成效倍于一个one-or阵列因此,two-drive 30阵列使用提供了一种能力吉字节驱动30亿字节,而three-drive阵列提供了一个总容量为60亿字节。
而不是一个单一的镜像的驱动器,数据分布在整个3次上篮在理论上,三分之一的three-drive数组是使用了数据备份、胎次、及修正错误的数据。如果一个驱动器失败,剩下的两个数据驱动将足够使系统运行,并重建失败的驱动器。
