RAID 0 is known for high read and write speeds, but it is very fragile in terms of reliability: if one of the drives is out of order, all the data is going to be lost. In fact, this type is not much of a disk array because it lacks redundancy. 
On the contrary, RAID 1 is a very reliable solution, as all the data is duplicated to the other disk, but this approach affects the read and write speeds of the whole array. 
If you have a few spare drives, you can upgrade the existing disk array to RAID 5 which offers a good improvement in reliability compared to RAID 0, and gives a speed boost in comparison with RAID 1. In the end, you get a RAID 5 system, which is both reliable and powerful enough to process your data faster. In today’s video, I’m going to show you how to migrate from RAID 0 and RAID 1 to RAID 5 without losing your precious data in the process.

Changing from one RAID level to another may take several steps. At first, you’ll have to convert it into an interim level, and then into the type you would like to have. For example, to change RAID 1 into RAID 6 you need to convert your system into RAID 5, and only then will it become possible to convert it into RAID 6. On the Internet, you can find a lot more information on all possible variants of changing from one level to another, and this video tutorial will help you do it step by step.
