Description

Technical Field

[0001] This invention relates to the field of solid-state drive (SSD) technology, and in particular to a method and apparatus for controlling the data transfer rate of an SSD. Background Technology

[0002] With the rapid development of information technology, solid-state drives (SSDs) have been widely used in the field of computer storage. The data transfer rate of SSDs is crucial to the performance of the entire computer system.

[0003] Traditional solid-state drive (SSD) data transfer rate control methods are primarily based on fixed-rate settings or threshold-based judgments. Fixed-rate settings involve setting a fixed upper limit for the data transfer rate based on the SSD's model or rated speed. Regardless of actual system operation, the data transfer rate will not exceed this set value. However, fixed-rate settings lack flexibility and cannot adapt to the dynamic data transfer rate requirements of different application scenarios. Threshold-based control methods adjust the data transfer rate when the SSD's temperature or queue depth reaches a certain threshold. However, threshold-based control is often too simplistic and coarse. Adjusting the rate based on a single threshold is prone to misjudgments. Furthermore, different SSDs vary in their heat dissipation performance and internal architecture, making precise rate control impossible with a uniform threshold setting. Summary of the Invention

Therefore, if the application type is determined to be a system utility program, the transfer rate control device obtains the maximum and minimum data transfer rates of the target SSD. Based on the current data transfer capacity and the maximum and minimum data transfer rates, it determines the first current data transfer rate of the target SSD and controls its data transfer rate accordingly. That is, when the target SSD transfers data from the system utility program, it transfers the data at the first current data transfer rate. The formula for calculating the first current data transfer rate is as follows:

[0144] .

[0145] in, Indicates the current data transmission rate. Indicates the minimum data transfer rate. Indicates the maximum data transfer rate. This indicates the current data transmission capacity.

[0146] Step 502: If the application type is a network communication application type, then based on the current data transmission pressure capacity, maximum data transmission rate, minimum data transmission rate and network latency coefficient, determine the second current data transmission rate of the target solid-state drive, and control the data transmission rate of the target solid-state drive with the second current data transmission rate.

[0147] Optionally, network communication applications have certain requirements for the timeliness and continuity of data transmission, while also taking into account the network environment and data transmission pressure. Therefore, if the application type is determined to be a network communication application, the transmission rate control device obtains the maximum and minimum data transmission rates of the target solid-state drive, as well as the network latency coefficient. The network latency coefficient ranges from 0 to 1; the higher the network latency, the larger the network latency coefficient.

[0148] Furthermore, the transmission rate control device determines a second current data transmission rate for the target solid-state drive based on the current data transmission pressure capacity, maximum data transmission rate, minimum data transmission rate, and network latency coefficient. It then controls the data transmission rate of the target solid-state drive using this second current data transmission rate. Specifically, when the target solid-state drive transmits data for the network communication program, it transmits the data at the second current data transmission rate. The formula for calculating the second current data transmission rate is as follows:

[0149] .

[0150] in, Indicates the second current data transmission rate. This represents the network latency coefficient.

[0151] Step 503: If the application type control includes entertainment creation application type, then based on the current data transmission pressure capacity, maximum data transmission rate, minimum data transmission rate and user experience sensitivity coefficient, determine the third current data transmission rate of the target solid-state drive, and control the data transmission rate of the target solid-state drive with the third current data transmission rate.

[0152] Optionally, entertainment and creative applications typically have high bandwidth requirements for data transmission. However, under heavy data transmission pressure, reasonable rate adjustments are necessary to ensure a good user experience. Therefore, if the application type control includes entertainment and creative applications, the transmission rate control device obtains the target solid-state drive's maximum and minimum data transmission rates, as well as the user experience sensitivity coefficient. The user experience sensitivity coefficient ranges from 0 to 1; the higher the user's sensitivity to the experience, the larger the user experience sensitivity coefficient.

[0153] Furthermore, the transmission rate control device determines the third current data transmission rate of the target solid-state drive based on the current data transmission pressure capacity, maximum data transmission rate, minimum data transmission rate, and user experience sensitivity coefficient. It then controls the data transmission rate of the target solid-state drive using this third current data transmission rate. Specifically, when the target solid-state drive is transmitting data for an entertainment creation program, it transmits the data at the third current data transmission rate. The formula for calculating the third current data transmission rate is as follows:

[0154] .

[0155] in, Indicates the third current data transmission rate. This represents the user experience sensitivity coefficient.

[0156] This invention combines the current data transmission pressure capacity and application type to control the data transmission rate of the target solid-state drive, so that the target solid-state drive transmits data at different data transmission rates when facing different application types, thereby improving the flexibility of solid-state drive data transmission rate control.
