Is it safe to use the laptop while copy/paste is active?


Mar 15, 2022
Hello. I often make large transfers from one device to another, as well as from one folder to another within the laptop's SSD, and from the SSD to the USB flash drive. Most of the time, i run Topaz programs, and other heavy programs, leading to the point where the CPU usage of my CPU is 85-100% most of the time. Sometimes the CPU usage stays at 100% for 30 minutes to 1 hour, or even longer.

If i start copying 100GB of data (files: .jpg, .txt, .wav, .mp3, .mp4, .mdl, etc...) from the SSD to the USB, while the CPU has been overloaded for hours, and will continue to be heavily overloaded during the copy/paste process, will this cause problems during the copy/paste transfer? For example, if the CPU is overloaded with multiple tasks and must "think" about many other tasks, not only for the copy/paste task, could this make the CPU forget to transfer a certain file, meaning some of the data i want to be transferred won't actually be transferred, because the CPU will get confused by the other tasks, will not be able to see the file, will skip the file, and will forget to copy this file, too?

Can such a problem happen?
If you can corrupt or otherwise make the system unreliable by keeping the CPU at 100%, then by golly, I'm surprised my overnight Handbrake runs haven't produced garbage.

In all seriousness, it's safe. The CPU doesn't get confused because there's a bunch of things going on at the same time and there are mechanisms in place to ensure file transfers are reliable. The only time a file transfer goes south is if the drive disconnects from the system randomly or the computer has an unexpected reboot/power loss. However, I will say the other thing to worry about is if the CPU can maintain its temperature under the maximum rated limit, which is generally 100C.

To further put your mind at ease, you know those movies Pixar makes? It generally takes hours for them to produce a frame. So that's a bunch of computers running at 100% for probably a few weeks straight. If computers got unreliable because they were kept at full load for a long period of time, I'm surprised Pixar is able to make any movie

Just the other day, I copied 10TB of data from my NAS, through my PC, to a 16TB drive connected via a USB - SATA dock.
100 times the data space you're talking about.

Took many hours.
Meanwhile, using the system for all other things. And the NAS was doing whatever it does at the same time.

Don't will be fine.
Computers are made to do this.
