Now we are passing over to copy speed.

Copying is actually a work of two simultaneous threads: one if reading and another one is writing. And RAID 0 arrays turned out to be made best of all for this job. Again, scalability is evident.

The second batch of copy tests doesn’t bring us any surprises. RAID 0 arrays are ahead, mirrored arrays are slightly behind a single HDD and a RAID 0 array of 2.

Now let’s enlarge our cluster! :)
