Practically my second document folder and number one for shared projects. The 15 GB limit for the free version is more than sufficient, if you are not throwing videos at it ;•). And the processor intensive burst that could happen in the past have completely disappeared on my latest PC.
Consumes 30-50% of my CPU continuously, even though it says "synchronized" and no data are transferred. Has to be stopped and started every now and then to stop this behavior. Unreliable CPU power eater.
I've used it for a month. Now it's impossible to syncronise my computer with Drive on web. "Impossible to have a connection". My wireless line is regularly working.
