lexar the just released, the original price was supposed to be around $ 110, so 110 euros (currently 119 dollars and 130 euros in December 2014) SHIFT price, the price on all sites increased to 148 euros, mistake lexar who announced the original price was around 110 or swelling of price christmas for them? we'll know more in January)
I based on several tests to have an average speed of the card, so it is more efficient than the Sandisk, but keeps the same principle, sacrifice speed for size.
Smartphones today have somehow hard to go faster than 25 mb / s write so it is well, for against it necessarily means that the card can not be used in new gopro 4 hero because the required speed for its models is 45 mb / s write and anyway the current models only accept cards up to 64 gigabytes (32 gopro hero for basic model)
The good side is that with a read speed of around 50 mb / s you can embed rip your collection or watch bluray VOD smoothly, already my old 64 Sandisk Ultra lets me go do it with file 4 gigabytes, and with that speed reading, you will have no latency of reading large files, pc on the playback speed is also good to quickly unload the large files such as photo or map video.

SEQUENCE INFO:
What is the number on some memory card, XYYY? on lexar it is 633, so what's the number? is the read reference, it takes the standard playback speed of the CD-ROM that was 150kb / s ... I know today its serves absolutely nothing but good, manufacturers continue to use this reference of another age.
Briefly here is a little help to the conversion:
x100 = 15m / s x633 = 94.95 So, that is why we say that the fact Lexar 95MB / s read (rounded up)

if that comment helped you see more clearly thank you to note, look for multiple card speed testing takes time to make a correct average
