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?

The main concern would be resilver times if a drive in one of the HW RAID0's fails. The resilver time would be similar to one huge disk drive since there would not be any useful concurrency.
