Good sharing?

narod.yandex.ru Files are stored for at least 3 months. Storage time can be extended any number of times, or it is extended automatically if the file is downloading. The maximum file size to 5 GB. The number of files is not limited. The use of two years, quite happy.

Tend to use people or rghost.ru

The Dropbox account can be used as a sharing and shaping of external links there.
However, the total number and volume of files will be very limited.

In GoogleDocs, open access, then an external reference to the file in sokraschatel links.

Mediafire.com
*unlimited space
* the file size limit 200 MB
*Files are kept indefinitely if you poseses Account t. 30 or 60 days

I use UploadRobots (http://uploadrobots.com/
It is true there is a limit on file size to 10 MB. The total size of the host 4 gig, kept forever, no advertising.
You can use ZumoDrive. Cloud service for synchronization. You can share links. Restrictions on the file size no limit box of 1 gig, if training is 2 gig. For a small fee you can increase the size of the box, while downloading no advertising. Kept forever.
Well, all sorts of traditional SkyDrive, etc.

Drop.io — up to 100 MB, password, term of storage, the ability to add/delete files, etc.

Ubuntu One, like dropbox, allows you to share the files with direct links. Don't know how they have limits, but worth a try.

files.mail.ru — though personally I do not like it, but you can come. After registration you will get better.

In General, I think, how important is speed. If you need to share a few text documents, then, in principle, can use any service with the captcha and waiting. If you need to upload more files, search for services which do not limit the speed. Look in the direction of dropbox and similar.
