My point was, NCBI and EBI use Aspera, which has a proprietary way to transfer file, you need their client for a fast download... but don't care about that I don't like that approach.

Why are they not using torrents ? Which is the sense of biotorrent ? Just share "personal" data or replicate/mirroring other databases ?

I must admit that I need just some SRA file for testing tools. I don't think I will download many sra data in the near future, I can wait 50mins using regular ftp.

It was more, which is your feeling with sra and your experience.
