One remark - write intent bitmaps will make it perfectly fine (orders of
magnitude faster). I'm not sure how the feature looks from performance
point of view these days though.

My "forever and a day" RAID6 build/rebuild comment may have been taken
out of context.  The original post was inquiring about running a qty 6
SATA disk md RAID6 array on a standard 132 MB/s PCI bus, using three 2
port PCI SATA cards on the single PCI bus.  My comments were focused on
the PCI bottleneck in such a setup causing dreadful array performance.
