A method for data storage includes receiving data items associated with respective logical addresses for storage in a memory that includes multiple memory units. Respective estimates of a performance characteristic are obtained for the multiple memory units. A mapping, which maps the logical addresses to respective physical storage locations in the multiple memory units, is adapted based on the estimates so as to balance the performance characteristic across the memory units. The data items are stored in the physical storage locations in accordance with the adapted mapping.
