thank you Jon and Kenny
It has nothing to see with USB 2.0 or 1.0; my Kingston key is quick and compatible with both, and home as well as job computers are 2.0
I tested with other computers; 2.45Mo file takes more than 3 minutes to save on key

Of course I immediatly after connection save on HD, but when I forget it, I am stuck for minutes.

Kenny, it would be nice if you could tell me which Key you use

Hello,
I very often have my models on a usb key to go from home to office, often with large models.
Sometimes I forget to save on HD, and the automatic savings is launched on USB key, and there is the problem; I get stuck for minutes, sometimes 5 minutes waiting for the model to save, and with the impossibility to stop the saving unless breakink key integrity.

Why is saving on USB key is so slow; I chose a rapid kingston 4Mo key but it did not change anything.
