Brian from Backblaze here.  If we do a full pod swap for a blank, we are disk &#x2F; CPU limited in the rebuild, not 10 Gbit&#x2F;sec limited.  We have the rebuilds up to taking about 3&#x2F;4ths of the 10 Gbit&#x2F;sec link but we continue to try to change the software and buffering to get this higher.<p>It&#x27;s MUCH better to lose only one drive, because we distribute the rebuild CPU task across all 20 CPUs in the tome and we can get it synced back up in a few hours.  All the chattering back and forth still doesn&#x27;t come anywhere close to maxing out the 10 Gbit.<p>For uploads, each individual pod has a 10 Gbit&#x2F;sec connection, so ACTUALLY the vault has an aggregate of 200 Gbit&#x2F;sec facing towards the internet.  However, every byte that a pod accepts it has to ALSO retransmit that internally so that cuts the actual theoretical upload rate to 100 Gbit&#x2F;sec for a properly parallelized application.
