"For Backblaze Vaults, we threw out the Linux RAID software we had been using and wrote a Reed-Solomon implementation from scratch. It was exciting to be able to use our group theory and matrix algebra from college. We’ll be talking more about this in an upcoming blog post."
I hope I'm not the only one uncomfortable about this. I mean, I understand the need for greater flexibility and features that MDRaid doesn't provide, but this wording stinks of NIH and rebuilding the wheel from scratch "because it was fun", discarding the maturity and reliabilty of established software. And data storage is all about reliability.
I hope I'm just reading too much from this, and it isn't actually representative of Backblaze's engineering practices.
