G-drive works great if you need mobile access. But I ended up throwing out the add-on from my computer because loading / unloading of the files from G-drive is painfully slow. You can't blame for this to Google or G-drive shell extension because the bottleneck is the network speed. My 3Mbps download / 1.5 Mbps upload network was hopelessly failure. On top of that, if your computer is on the routine of regular upate-check or virus-database download or youtube streaming etc. that occupies someof your bandwidth, then the performance would be so bad that this extension would turn out practically useless. I ended up carrying a patriot XT.

Also, depending on the explorer setting, the add-on might cause unexpected crash because everytime you open the "My Computer" it tends to access G-drive through login routine, which has some glitches. I uninstalled this extension because of such problems.
