I am considering creating a raidz3 consisting of 16 disks. The recommendation is to use 11-15 disks for a raidz3, I think. If you use more disks, there might be problems. Such as long resilver times, etc. For instance, on FreeBSD forum someone tried a raidz2 of 20 disks, and it was very bad. Resilver times were very long, it would almost not finish. They redid the zpool with several raidz2 and perfomance skyrocketed. So, has anyone tried a 16 disk raidz3? How bad was it? I dont mind a slight penalty, but I dont want something that is very bad.
