RAID is used in disk arrays to protect data against disk failure and also to offer performance enhancements. But not all RAID levels are the same and each one has its costs and benefits.

I was looking for visuals to help me teach about storage when I came across this. This is really well done.

There is an error when he talks about RAID 0 + 1. If you lose one drive out of the striped pair, you lose that whole group and would need to rebuild from the other mirror pair. What he said implied that you can lose a single drive and recover from the other half of the striped pair which is not possible.

Hi. I want to build a Raid 10 with 4 HDDs. But now I ask myself what if my motherboard breaks down at some point ? Can I simply connect the 4 HDDs to a new and more modern MB that can also run Raid 10 and it will continue to run (plug & play) as before ? Or do I have to set up and format Raid 10 and then have to upload the data from a last backup ?
Thank you
