Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
So a 16 minute video that poorly covers what a 3 paragraph summary can? I skipped around and there were several references to vdevs as pools, so the credibility of anything said here goes out the window.
Increasing redundancy decreases space efficiency. This isn't news.
This video is a little bit of everything. It is supposed to say how to organize ZFS pool make of 60 disks. Yet it seems it introduces what is ZFS in general, what are vdevs. Who exactly is the target of the video? People who have money for 60 disks likely already know it and have known about ZFS for years. If they are given 60 disks to organize by their company then they are sysadmins and they also know these things. If they don't, they run Windows:P
This would made sense if it focused on more advanced issues such as "under what assumptions does the cache matter", or at least "effect of the layout on resilvering time". Why do you compare RAIDZ-2 with mirrors in terms of speed? Why not RAIDZ-1 or RAIDZ-3? They are of different redundancy levels.
