I'm a bit confused about what kind of upload speed I should expect from Dropbox. My internet connection here in the UK is 270Mb down and 26Mb up. Speed tests via a variety of sites confirm that I am getting these speeds. I mostly deal with quite small file sizes and these synch instantaneously. However, when I try to upload a 10GB video file to Dropbox, it takes literally several hours. Is this correct for the size of file I am uploading and the upload speed I have?
