Now let’s take a look at file copying speed within the same partition:
RAID0 and RAID5 arrays demonstrate perfect scalability of the results on the number of hard drives included into the array in all file patterns. However, the overall level of performance is not very high, I should say.
RAID10 performance is almost the same as that of RAID0 of two hard drives. And RAID1 is stably faster than a single HDD.
Now it is the time for another copying test – from one partition to another:
Just as in the previous case RAID0 and RAID5 arrays scale up very nicely depending on the number of drives in the array, and the performance of RAID10 equals to that of two-drive RAID0.
RAID5 array is pretty fast in Install and ISO patterns. RAID1 array performs very well in ISO pattern, too.
