I am reading/writing to a SD card using a microcontroller that operates on the 5v logic level.. I have successfully used this circuit:

Is that a "proper" circuit? Is it better to use one of those conversion ICs (MAX something?)?
Also, can I use a voltage divider for the 3.3 supply to the SD card since it draws minimal power?
Thanks!
