Really... how much faster can an SD card be over a memory stick. I need a Yamaha style from a memory stick it loads as fast as internal styles. I need a sound, same thing it loads as fast as the built in sounds...registrations, songs etc all pretty darn fast, in fact almost load instantanously. SD Cards are faster than that? I would say in a race it would be a photo finish
To each his own, and if you're happy that's what it's all about...right?
