Do what you want with LG Optimus L7 P700

I purchased the 16GB version.

Reading speed in a USB Reader is as short as 20 MB / s and writing at around 12 MB / s.
The map is therefore sufficiently fast and much faster than an ancient 2GB No-Name Card.

The map is not much more expensive than no-name cards from the bargain bin, has a 30-year warranty and works fast and flawlessly.

Best Buy? Yes!
I forgive five stars.
