> I have a file server running AMD Phenom II 955 that I'm thinking of replacing with a RPi. Is there a practical way to have RPis manage a software RAID? I did this using an rpi2. It is non-trivial in terms of effort. In a practical sense the rpi is limited in terms of power to the USB ports, so any build with 2+ HDDs and some sort of wireless USB keyboard and mouse dongle will use up too much power. In other words, I had to buy a powered USB hub. I used mdadm to do a software RAID, which more or less worked out of the box but took a while to clone the original drive. Throughput wasn't amazing for anything except occasional pulls and puts; I wasn't going to stream 4K video off of this, though I did have some luck with Subversion and music streaming. It was clunky enough that I got a Synology box a year and a half later and never looked back.
