Basically you are comparing a 4-drive RAID-6 to a 4-drive RAID-10. I
think the RAID-10 will be faster for streamed reads, and a lot faster
In this 4 drive configuration, RAID6 might be ever so slightly faster in
read performance, but RAID10 will very likely be faster in every other
category, to include degraded performance and rebuild time. I can't say
definitively as I've not actually tested these setups head to head.
for small writes. You get improved safety in that you still have a
one-drive redundancy after a drive has failed, but you pay for it in
longer and more demanding rebuilds.
Just to be clear, you're saying the RAID6 rebuilds are longer and more
demanding than RAID10. To state the opposite would be incorrect.
Yes, that is exactly what I am saying.
