Accessories: 5 out of 5
Lifetime warranty, actually useful software, the usual clamshell card holder, a micro-SD to full size adapter card, and a UHS-II micro-SD USB card reader. What more could anyone ask for?!
Read performance: 22 out 25
The read performance that this new series has to offer is rather impressive. Put simply this small card just proves that you do not need to get a full sized SD card to get ‘full size’ performance.
Write performance: 35 out of 40
For a SD card this new Professional 1800X series is extremely fast; however, for a micro-SD series it is insanely fast. With very few exceptions we cannot see anyone not being satisfied with what it has to offer.
Warranty: 9 out of 10
Just as with the all Professional series, the Lexar 1800X Professional series come with a lifetime warranty that is backstopped by one of the largest NAND manufactures in the world: Micron. This means that the Lexar Professional lifetime warranty is indeed a true lifetime warranty and will be honored for your lifetime and not the cards! The only minor issue is RMA’ing one may mean shipping it to the States. If you have a Micron RMA depot in your country, then you can consider this card a perfect 10.
Value: 19 out of 20
With standout performance in both modes the new 1800X is an excellent choice for consumers look for either a micro-SD card or even a full sized card. Mix in a reasonable asking price and the result is pretty hard to argue with – it is just that good.
Final Score: 90 / 100
We honestly were blown away with what this extremely small card had to offer. No matter what the test this card easily held its own against all comers. To be blunt, we never thought a micro-SD card could be this fast. The fact that is so darn fast in both UHS-ii and UHS-I mode is just a bonus.
