An indication to perform a garbage collection process for multiple erase blocks at a storage array that includes multiple storage devices may be received. Characteristics for each of the erase blocks may further be received. Valid data at each of the erase blocks may be identified. Furthermore, valid data from different erase blocks of the multiple erase blocks may be grouped based on a similarity of the plurality of characteristics between the valid data from the different erase blocks. The valid data from the different erase blocks may subsequently be stored at another erase block at the storage array.
