In consumer and enterprise world, SSD Performance is the main quality constraint. SSD performance parameters are classified in terms of lOPS, Throughput, latency and Quality of service(QoS). SSDs processes millions bytes of data with certain latency and throughput for read, write and mixed operations. But Quality of service is not guaranteed by SSD vendors for single user. However, Enterprise/server SSD storage must meet a Quality of Service (QoS) level with the given requirement to ensure the study-state performance over long period of time.
