Look, it's hard to know what VDEV layout is the best for #TrueNAS CORE and SCALE. Rich has built numerous different disk layouts and never really saw much of a performance difference between them. So, he's endeavoring to find out. In this video, we show you the results of our testing on which data VDEV layout is the best and whether read/write caches (L2ARC & SLOG caches) actually make a difference. Spoiler alert, we had to go get answers from the experts!
