The SRTM data is the altimetric data created by the Shuttle Radar Topography Mission, and it is available in a resolution of 3-arc second (90meter) outside the USA. Version 3.0 has finshed SRTM data, DEM void's filled, clips of the coastlines.

Methodology of SRTM V3.0

WebGIS to download tiles of SRTM V3.0

This server has the option of mirror picking and a direct access to the FTP

I tested the 3 mirrors for velocity of download the srtm_48_05.zip file, my location is Portugal and my ISP says that my ADSL is at 24mbits (Ya shore......) and the test was at 4:54PM (Lisbon Time) in 29 Nov. 2006
HTTP connection of CSI server: 268kB/sec
FTP connection of CSI server: 154kB/sec

HTTP connection of JRC(IT) server: 254kB/sec
FTP connection of JRC(IT) server: 470kB/sec

HTTP connection of Kings College (UK) server: 118 kB/sec
FTP connection of Kings College (UK) server: 351 kB/sec

So the velocity doesn't change much but it seems (at least for me) that the Italian server is better for my location

Also there are some FTP servers with version 2.0 and 1.0:
