Suppose I want to build a 100-drive storage system, wondering if there is any
disadvantages for me to setup 20 arrays of HW RAID0 (5 drives each), then setup
ZFS file system on these 20 virtual drives and configure them as RAIDZ?
I understand people always say ZFS doesn't prefer HW RAID. Under
D'oh. I shouldn't answer questions first thing Monday morning.
I think you test this configuration with and without the
underlying hardware RAID.
If RAIDZ is the right redundancy level for your workload,
you might be pleasantly surprised with a RAIDZ configuration

The main concern would
imho, not a good idea, any two hdd in your raid0 fail zpool is dead
if possible just do one hdd raid0 then use zfs to do mirror
raidz or raidz2 will be the last choice
