Many free online disk drives have been introduced before, such as the UploadingIT free online disk space, but the speed of most of them is not satisfactory. Now, Hookle strongly recommends another 100% free online disk drive that went online on March 6, 2007, called 51ok. It does not limit the size of the space, does not limit the size of individual files, and does not limit the upload speed. You can upload 1 to 10 files simultaneously. If there is any drawback to speak of, it would be that once you start uploading, you cannot cancel it unless you refresh or click "my files" to terminate it. Once again, speed is not an issue.
