Super-slow RAID rebuilds: Gone in a flash?

Rebuilding SSDs should be faster than spinning disk drives

Analysis RAID rebuilds are too slow with 4, 6 and 8 and 10TB drives. So erasure coding is coming in to shorten the failed disk data rebuild time and also use less capacity overhead. What happens when SSDs are used instead of disk drives? Will RAID be more or less acceptable than with disk drives?"
