Yev from Backblaze here -> Yea, we raid across different pods w/ Reed Solomon (https://www.backblaze.com/blog/reed-solomon/ https://www.backblaze.com/blog/reed-solomon/). With these that would be very costly, but the benefit for us is that an entire pod or two can go down and it's still OK.
- mixedCase 10y agoHow would you say your solution compares to groups of 10 drives in RAID6 configuration when it comes to safety, storage and availability?
- atYevP 10y agoYou can read a bit more about our infrastructure -> https://www.backblaze.com/blog/vault-cloud-storage-architecture/ https://www.backblaze.com/blog/vault-cloud-storage-architect... - Right now we essentially "RAID" across multiple racks - so we can lose an entire rack and it wouldn't really affect us too much. Having 10 drives in RAID6 is great - having those 10 drives be in different physical locations on separate power circuits is even better :D
