A method for managing data. The method includes receiving (302) a first request to write data to persistent storage and in response to the first request, writing (312) the data to a short-lived block in the persistent storage, where the data is short-lived data or data of unknown longevity. The method further includes performing a modified garbage collection operation that includes: selecting a first frag page in a first block, determining that the first frag page is live, and migrating, based on the determination that the first frag page is live, the first frag page to a long-lived block in the persistent storage, where the long-lived block is distinct from the short-lived block and wherein the long-lived block does not include any short-lived data.
