-## Performance and cost impact 
+## Performance impact 
 
 Replication can affect performance as traffic increases to synchronize all copies. 
 
-Database storage costs also increase:
+## Memory limit
 
-- For Fixed plans, single-zone and multi-zone replication effectively doubles storage costs
+For both Fixed and Flexible plans, replication doubles the memory limit you need for your database. 
 
-- For Flexible and Annual plans, replication requires additional shards and can affect subscription costs
+For Fixed plans, The size of the plan you choose includes replication. Therefore, if you choose replication, the dataset size you can use is half of the stated plan size. For example, if you choose a 1GB plan, Redis allocates 512 GB for the memory limit, and the other 512 MB for Replication.
+
+For Flexible and Annual plans, you also need to double the amount of memory needed if you choose replication.

 - Memory limit represents an upper limit.  You cannot store more data than the memory limit.  Depending on your other selections, available memory for data may be much less than expected.
 
-- Replication doubles memory consumption; that is, 512MB of data requires at least 1GB of memory limit when replication is enabled.
+- Replication doubles memory consumption; that is, 512MB of data requires at least 1GB of memory limit when replication is enabled. This also affects Fixed plans. For example, if you subscribe to a 1 GB Fixed plan, Redis will allocate 512 MB for your dataset and the other 512 MB for replication.
 
 - Active-Active also doubles memory consumption and the effect is cumulative with replication's impact. Since Active-Active requires replication to be turned on, the memory limit impact can be as large as four times (4x) the original data size.
