This breakout board has an on-board 5v-3v regulator, an activity LED, four #2 mounting holes, push-push card socket and 0.1" headers so you can get it on a breadboard or use wires.
Dimensions (without 0.1" header):
To use with an Arduino, connect GND to ground, 5V to 5V, CLK to pin 13, DO to pin 12, DI to pin 11, and CS to pin 10. Then you can use the wonderful SDfatLib which supports FAT and FAT32 SD cards.

If you're new to manipulating SD data files, you'll be better off on this. Leave that bare breakout for the micro sd socket by itself alone, and start here.
The level shifter on this part of the key of making it easy - the activity light is a nice thought and a good indicator for projects without displays. That will help eliminate a lot of variables whilst developing your project. It... just works!
It's compact, clearly labelled, thoughtfully designed, and you can press your thumb against the card edge and get clear access.
HOWEVER... The price tag causes me to drop this down to 4 stars. I have a feeling the level shifter IC may be the cause of increase in price, and for £18 you pay, you can buy yourself an SD Card Reader for your PC. Although i have bought this, it has saved me doubting wether my SD Micro Card was working at all.
