Hi!

I just read

http://www.amplidata.com/pdf/The-RAID-Catastrophe.pdf

According to that – well marketing white paper – it offers huge advantages over just replicating the data several times.

What do you think about it?

Can BTRFS use Forward Correction Codes to allow scenarios like 4 out of 12 drives can fail? And can this provide an advantage over regular replication?

Ciao,
