Yes a hardware RAID controller will (or should) be faster than a software solution but, unlike your other examples, a HW RAID configuration is tied to the hardware and if the HW dies you can't access your data w/o identical, or confirmed compatible, replacement hardware. In this case, software RAID is "better" as you can simply move your configuration to another system as needed.
Your other examples are not really good comparisons for values of "better" other tha
My preference is software raid because you typically get added features like snapshots, dedup, etc that would cost a ton if done in hardware, and software raid still leaves plenty of compute resources left over for applications like plex. Oh and ZFS is pretty much the gold standard for home nas.
exactly this. software is much easier to work with and recover, and its futureproof. hardware raid might have its place, but I question the value of raid at all. you can use a software stack like gluster that just duplicates and distributes files on standard filesystems, or do something super basic like rsync your files once a week to a backup drive (local or remote). what you loose in functionality you might make up for in simplicity. it just depends on how much value you put on different features. definately ive seen more data lost on failed hardware raid that looses the ability to see some drives and using proprietry algorithms than software raid.
Why can't there just be hardware ACCELLERATION? Like a programmable RAID controller. Or festures/interfaces that make it hardware fast but with whatever code you want to happen.
An interesting idea, but it seems like it tries to occupy a strange niche between a pure software stack like ZFS, and just splitting your storage out to a separate box entirely.

I'm interested as well, and I want to read suggestions from people who have been there.

Is hardware RAID better than software RAID?
Is a GPU miner better than a CPU miner?
Is an H264 decoder chip better than software?
Is AES-NI better than general CPU encryption/decryption?

In this case you have to define "better".
