HTTP is generally faster, this is because HTTP just sends the datafile and assumes that you've received it. FTP is a little slower and it uses 2 channels. One for flow control and one for data packets.

 

As a rule of thumb, anything under 20MB is ok for HTTP, but anything bigger i'd go with FTP, and if you're using HTTP you should ALWAYS MD5 your files.

Why? You just said that HTTP is faster. And what is MD5?

HTTP is designed for transfering lots of very small files. Like web pages. It isn't supposed to be used for large file transfers. FTP has built in error checking and control flow operations which allow it to send, route and receive packets effectively even for large files.

 

MD5 is a hashing operation or checksum. Most download sites will post the MD5 checksum of a file so that you can ensure that the file has now been damaged in transit.
