Rapid gator is one of the original file hosting and sharing sites and is well trusted with many pornsites and used to host files. Of course you can download these files for free and without an account, however if you wish to speed up your downloads you need to signup.
When you subscribe, you'll get no queues for file downloads, the ability to download huge files (up to 5GB - per file!) and no adverts. You'll also be able to download more than one file at a time. Since Rapid Gator is used quite a lot, it's worthwhile looking into it.
A months subscription will cost you $12.99 and this not only gives you all the downloading benefits but file storage too so you can store your own porn collection with peace of mind that it's not going anywhere.
