Initially, both of my office desktop computers were performing well. They were reliable machines for my tasks. 

However, today, I encountered an issue with System 2. It experienced a significant decrease in copying speed when transferring data from the internal NVMe to an external SSD. Normally, both System 1 and System 2 were able to copy large files at a speed of 350+ MB/s from internal storage to an external device. But today, System 2 started copying at a disappointing rate of only 35+ MB/s.

I vaguely remember complaining about a similar issue in the past where System 2’s copying speed dropped suddenly after initially performing well. However, the problem seemed to resolve itself back then. Yet, today, the slow copying speed persisted throughout a ten-minute process of copying a 17 GB file.

I tried troubleshooting by checking the external connections, swapping SSD disks, and testing different USB3 ports on System 2. Interestingly, when I tested System 1’s performance in copying the same file to an external device, it maintained the high speed of 350+ MB/s. But when I attempted to copy the same file from System 1 to System 2 and then to an external device, the speed dropped to 35+ MB/s again.

Furthermore, transferring a slow-copying file from System 2 to System 1 resulted in no speed issues. It was only when copying from System 2 to an external device that the slow speed persisted. System 2’s overall performance seems comparable to that of System 1, except for this sudden copying problem.

Despite the setback, I am optimistic that with the support of my friends, I will be able to tackle this issue. The lightning-fast speeds observed when transferring files over Wi-Fi and between internal drives suggest that the problem may lie with the USB3 ports on System 2.
