Y’all must be doing something wrong because HW raid has been hot garbage for at least 20years. I’ve been using software raid (mdadm, ZFS) since before 2000 and have never had a problem that could be attributed to the software raid itself, while I’ve had all kinds of horrible things go wrong with HW raid. And that holds true not just at home but professionally with enterprise level systems as a SysAdmin.

With the exception of the (now rare) bare metal windows server, or the most basic boot drive mirroring for VMware (with important datastores on NAS/SAN which are using software raid underneath, with at most some limited HW assisted accelerators) , hardly anyone has trusted hardware raid for decades.

  Y’all must’ve been doing something wrong with your hardware raid to have so many problems. Anecdotally, as an admin for 20+ years, I’ve never had a significant issue with hardware raid. The exception might be the Sun 3500 arrays. Those were such a problem and we had dozens of them.
  
  So what were you doing wrong to have so much trouble with the Sun 3500’s?

    They were olde by the time I got to administer them and they were failing every so often. They were a pain to work with as I recall, but again no lost data. They would beep with no issues sometimes. One thing that wasn’t their fault was a previous admin had set them up in threes with all but one disk in a raid5 array. They were wondering why performance was crap and one array would just drop every week like clockwork.
    
    Took a while, but I mirrored (VVM) the data off on spare 3500s set up properly. They ran okay then. It was just ancient storage. Glad to work on netapps now. So much smoother and sophisticated storage compared to the olden days. lol
