Abstract
The present disclosure generally relates to enhanced write performance by taking into consideration user write performance preferences as well as enhanced post write read (EPWR) scheduling. The user provides the write performance preferences to the data storage device. When a write operation happens, the data storage device checks the write performance preference for the current LBA as well as the write performance preference for the previous LBA. The data storage device will also check whether the current word line is scheduled for EPWR. Based upon the write performance preferences for the LBAs and the EPWR scheduling, the data can be written out of order to meet the user's write performance preferences. If the data is written out of order, the flash translation layer (FLT) is informed of the switch.
