Its implementation is similar to RAID, except distributed across servers and implemented in software.As with RAID, there are a few different ways Storage Spaces can do this, which make different tradeoffs between fault tolerance, storage efficiency, and compute complexity.

"Dual Parity - 8 HDDs + 1 GB WBC" get around 250 MB/s "HW-RAID6 - 8 HDDs" gets around 1250 MB/s Wow, so I think WBC caching helps but 250 MB/s, from a 24 drive array is kinda really messed up. Best way to do it is to just try and find out; it’ll be less than a RAID5 would lose, and I’m pretty sure it’ll be able to use all of the space since you have so many drives, but I’m not 100% certain. This means, that data is written and read to/from 4 disks simultanously while the other 4 disks per type keep the copy of each data stripe on the space. The Column Space Calculator will find a basis for the column space of a matrix for you, and show all steps in the process along the way.
