Let’s now check the copying speed:

The RAID0 is the best at copying files and its speed scales up well depending on the number of disks in the array. However the speed is still not so very high – today’s single desktop drives copy data much faster within themselves.

The RAID5 arrays are somewhat slower, but their speed also scales up depending on the number of disks per array. The mirroring arrays are only noticeably faster than the single drive and the 2-disk RAID0, respectively, when they process the Programs pattern.

The results of the second test cycle do not differ much from the previous numbers.
