I'd like to know why technically Dropbox is much faster than FTP? What kind of technology does it use?
I'm not talking about diff files, I'm talking about transferring new files in both cases, Dropbox is much faster.
I mean it, very much faster, maybe 10 times faster than FTP for files I uploaded. I will experiment again for bigger files later.
2What size, type, and number of files did you upload? How long did each of them take to upload? Where were you uploading the files to via FTP? Dropbox is not magic, the simplest explanation is that the FTP server you were uploading too has much less bandwidth than Amazon does. – user23307 – 2010-03-15T01:50:38.013
2if they already have it, it dosen't re-upload ;p – Journeyman Geek – 2010-03-15T03:23:06.863
4You say “new files”, but unless these files are fresh, random data, you are probably seeing the benefit of block-level syncing (like in rsync and other tools). – Chris Johnsen – 2010-03-15T03:32:11.570
1This is more of a hosting comparison imo, I know FTP servers that are faster than Dropbox and I also use multiple connections with Filezilla so the statements listed in this answers do not hold. – Tamara Wijsman – 2010-07-18T21:00:17.347
Dropbox does use de-duplication to save on storage space of common files, so it does not need to upload them if it has them already. – paradroid – 2011-05-09T15:53:54.623
