Mark,

These days disk space is easier to come by than time, in general. As Jeff points out, GeoTiff is fast (especially if you use TILEINDEX and MAX/MINSCALEDENOM layers for pyramid/overviews). But GeoTiffs tend to take up 10 to 20 times the amount of disk space of ECWs though...

  Is there any particular reason not to use tiles (e.g TMS)?

Hello,

Which format is faster ECW or Mr Sid for a large image? P.S. I don’t think I will be able to use a tile cache for the application I am developing.

Thanks
