全部性能 meaning in English

over-all properties

And you should use only one drive per ide channel to avoid sluggish performance - a slave device , especially if it s also part of the raid - 0 array , will slow things down so much as to nearly eliminate any raid - 0 performance benefit
同时，为了避免降低性能，每个ide通道上只应连接一个驱动器- -从属设备（尤其是当它也是raid - 0阵列的一部分时）对速度的负面影响几乎会抵消raid - 0的全部性能优势。
