I have a 256KBps connection today for the first time i used SkyDrive to upload some files (5MB) it took more than 2.5 minutes for me.
I tried it in Gmail = 1 min
Hotmail = 1.5 min
Which is the best secure service to upload your file. Also the one which did not suspend ur acc after certain year of inactivity. As i just wanted to have backup of my files.
