Together, drive cache and algorithms work to improve the transfer of data in and out of the drive and to make parity calculations for RAID 5 implementations.
驱动器缓存和算法一起可以提高数据进出驱动器的速度，以及为RAID 5实现进行奇偶检验。

Although RAID-5 can support failure of a single drive, RAID-6 can support two drive failures (though more capacity is consumed through parity information).
