Game installation on USB 3.0 stick slow - why?

[Unik]

Hello everybody,

since my SSD is full and I still have a 128 GB USB 3.0 stick, I occasionally install games on it. I could not find any loss of performance in games (strategy, role playing, shooter). The installation only takes a lot longer. Why is that exactly? USB 3.0 is actually quite fast in terms of writing and reading processes.

Thank you very much

The USB standard yes, the USB stick, not necessarily.
Especially USB sticks tend to lose a lot of writing speed when constantly under load.
They are not designed for such tasks and throttle down due to hitting thermal constraints.
They get slower so they don't damage themselves.
Reading is a lot easier task to do.

However, the installation speed is very slow from the beginning, or does the stick start throttling very early?

I have a SanDisk UltraFlair. I only feel it at a maximum of 20 degrees. I had written it full with various dates. I only had to lose speed with folders with a lot of smaller files. I hadn't made a real benchmark with a program.

I think a larger SSD makes more sense. Have only 256 Gb.

Yes, a larger SSD would clearly make more sense.
Even "just" a SATA3 SSD is faster than USB 3.0 could ever be.
SATA3 = 6 Gigabit per second.
USB 3.0 = 5 Gigabit per second.

Plus, the hardware is actually designed for such tasks and does not loose performance as fast as a USB stick which is designed for short time use.

if you have same issue as i did on external disk maybe its laptop issue and driver is a usb2.0 after vist brand laptop page and dl usb 3.0 to special external 3.0 port blue in my case then speed was high again. ( you might say wrong usb 2.0 driver on a 3.0 port... cough cough , what the hell went wrong here.
