You should do a test. Under macOS, some operations do not involve too many reads and writes to the SSD, and there will still be current noise at this time. For example, in Photoshop, most of the image zoom operations, this noise will be synchronized with the operation and appear at the same time. Because the memory is large enough and the picture is very small, the system does not need to use SSD as virtual memory (dynamic swap file), and no other programs are running in the background, so this picture scaling operation hardly involves reading and writing to the SSD hard disk. Why is the noise very synchronous with Photoshop zoom operation? I think there is only one reason, and that is that when scaling, the frequency and power consumption of the CPU, including the GPU, have changed. Therefore, current noise is generated. Of course, not only the operations under Photoshop can generate current noise, but any software with high load on other software will also generate similar current noise. I suggest that you perform some operation tests that can change the CPU frequency and power consumption in an instant, and try not to involve the operation of reading and writing the SSD. At this time, you will be pleasantly surprised.
