Abstract
Read Quality of Service (rQoS) in the solid state drive is improved by reducing latency for host random read workloads. Host read operations for random read workloads are prioritized in the solid state drive over program operations for garbage collection to reduce latency for random read workloads. The program time (tProg) and other associated latencies such as program-suspend-resume overhead, and firmware process overhead to dispatch the program are minimized by minimizing the number of program commands used for garbage collection while the solid state drive is performing read operations for a random read workload for a host read operation, allowing the solid state drive to prioritize host read operations for random read workloads while ensuring that there is no impact to the amount of written data that is on the solid state drive.
