Writes have to go through the transactor. Reads don't. So Datomic is a bit of a hybrid; writes are single point, reads are distributed. The storage layer is distributed automatically because it's decoupled from both the transactor and the peer. It's actually pluggable, too... you can use DynamoDB, Riak, Couchbase, Infinispan, Postgres, etc. which all have different performance and availability characteristics.
