Method for enhancing quality of service of solid-state drive and solid-state drive

A solid state drive, comprising a memory and a processor, wherein the processor is coupled with the memory, and a computer program capable of running on the processor is stored in the memory, wherein when executing the computer program, the processor implements a method for enhancing service quality of the solid state drive, the method comprising:

• obtaining a remaining storage resource corresponding to a write I/O request periodically, and determining a resource waiting time of the write I/O request based on a resource consumption rate of the write I/O request;
• setting a maximum scheduling delay time for the write I/O request according to the resource waiting time of the write I/O request;
• identifying a one or more types of a set of unprocessed I/O requests, obtaining a set of arrival times associated with the set of unprocessed I/O requests, and adjusting an order of the set of unprocessed I/O requests based on the set of arrival times and the maximum scheduling delay time;
• and
• processing the set of unprocessed I/O requests according to the order of the set of unprocessed I/O requests.

A method for enhancing service quality of a solid state drive, comprising:

• acquiring free space of the solid state drive periodically, and determining a maximum scheduling delay time of an erase I/O request through the free space;
• identifying one or more types of a set of unprocessed I/O requests, acquiring a set of arrival times associated with the set of unprocessed I/O requests, and adjusting an order of the set of unprocessed I/O requests based on the set of arrival times and the maximum scheduling delay time;
• and
• processing the set of unprocessed I/O requests according to the order of the set of unprocessed I/O requests.
