Systems and methods disclosed herein are used to efficiently manage low read data. In one aspect, a method includes, in response to detecting occurrence of a first event (e.g., PFail), writing low read data to non-volatile memory of a storage device with a fast SLC programming mode, distinct from a default SLC programming mode. Writing the low read data with the fast SLC programming mode: (i) includes using one or more memory programming parameters distinct from a default set of memory programming parameters used for writing data with the default SLC programming mode and (ii) takes less time per predefined unit of data than writing data with the default SLC programming mode. The method also includes: in response to detecting occurrence of a second event (e.g., host write command), writing data corresponding to the second event with the default SLC programming mode using the default set of memory programming parameters.
