In our today’s article we are going to compare the performance of RAID arrays of different types built of four HDDs of 8 different models. Among our testing participants will be 3.5-inch HDDs from all four leading hard drives manufacturers, including not only desktop but also special server models.

Copying within the same partition on a RAID0 is like reading: the trick is in having high-density platters and reading large files.

The picture does not change much in RAID10: the same three drives are ahead with large files. The Hitachi and the Samsung show their speed with small and medium files, though.

The Seagate ES.2 falls behind the leaders in RAID5 but the Samsung is surprisingly good with large files. The Samsung behaves oddly in RAID5: it is good at processing small files but does not like to work in RAID5 under server-like loads.

The standings are overall the same in the copy far test.
