Abstract
A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to maintain a plurality of virtual pools, wherein each virtual pool corresponds with an logical block address (LBA) range, update a counter of a virtual pool, wherein the counter corresponds to a health of the LBA range, and select, based on the counter, the virtual pool to program data to. The controller is further configured to maintain a counter for each application having data programmed to the virtual pool, where the counter is increased for each write operation to the virtual pool. When the counter equals or exceeds a threshold value, the controller is configured to send a warning to each application associated with the virtual pool having the counter that equals or exceeds the threshold value.
