This article explains the difference between High Throughput and Low Latency volumes.
The key difference between the two volume types has to do with with the replication behavior of the containers involved in these volumes, i.e., linear chain container replication and star chain container replication.
With linear chain container replication, if an update is written to container A, then A sends the update to B and B sends the update to C. But with star chain container replication, A would write to both B and C.
Linear chain container replication has higher throughput because the network of A is only used for one transfer and star chain container replication has lower latency because both replicas are updated with only one network hop.
Low latency volumes can be used where you have lot of small files while high throughput can be used where your files are generally big in size.
