The largest number of drives for my NAS rig as currently planned is a total of 5 disks and I would like the protection of raidz2.
This is the limit for two reasons: The case I want badly can only support 5 disks without modding, and the motherboard for this build only supports 4 disks; a total I have brought up to 5 using a cheap 1x controller.
Is a 5 disk raidz2 setup that awful? All the benchmarks seem to show the speeds jump a bit with 6 disks, but they don't seem terrible with just 5.
What if only 512 sector drives are used? All the "only 5 or 9 for raidz1" comments I've seen are directed towards 4k disks however I don't really understand the math behind that.
My NAS on a Gigabit router tops out about 50 - 60 MBs with samba. I think the slightly slower speed of a 5 disk raidz2 should still saturate that. I haven't seen this specific setup discussed, only glazed over mostly in benchmark threads.
