RS and XOR EC are definitely useful features for an object store that's storing from like tens of petabytes to exabytes worth of data but for a remote block device with a typical size up to a couple dozen terabytes I'm not so sure. Thanks for the link I will check it out
Edit: skimmed it, classic AI "analysis" - totally ignores all the crap io_uring went through
Buggy hasn't been my experience and the overhead should get smaller as storage grows. In any case, you'd get extra features such as S3, which would otherwise require running another service
