Perhaps at least a subset of people advocating software RAID have extensive experience with various high-end software and hardware RAID solutions?

- rconti 7y agoI'm struggling to think of high end software RAID solutions. I suppose backblaze pods are all software though, but I haven't personally worked with one; I'm not sure if they're primarily designed for capacity or performance. Through enough spindles at a problem, though....
- vardump 7y agoUltimately disks don't really care whether it's software or hardware that sends them the commands. Even hardware RAID is somewhat of a misnomer. Just like the disks themselves, it's just an embedded CPU, varying degrees of hardware acceleration, possibly battery/ultracap backup and a big software stack. Software RAID can achieve high capacity and/or performance. No difference in principle to hardware RAID there. You can use multiplexing for huge SAS backplanes in either case.
