RAID expansion would be nice, but we don't really require this in a software RAID.

Anyway, I just tried pulling a drive without warning the software ahead of time. It works great, with no interruptions (I was again streaming a media file while I pulled the drive). Right now, it is rebuilding. So, it seems like this software raid hot-swap works just as well as hardware raid.

My system is a Supermicro 1U 5015P superserver:
