As we have shown conclusively in this review the itty-bitty Lexar Professional 1800X micro-SD UHS-ii card gives almost nothing up when compared against ‘full sized’ SD cards; and even then the number of SD UHS-ii cards that can beat it is rather limited. Equally impressive is that in backwards compatibility mode (i.e. UHS-i mode) this card is every bit as fast as any SD card manufactured to date.
Put simply this is one potent little card that is cram packed with potential. In fact, it is so potent that many consumers are going to have a tough time justifying opting for more expensive series that offer only moderate improvements. This is especially true when you take into consideration the fact that it not only comes with micro-SD (UHS-ii compliant) USB card reader but a SD UHS-ii ‘full size’ adapter sleeve! This out of the box adaptability makes it tailor made for consumers who do not precisely know what SD standard their future devices will need, as well as consumers who wish to use one SD card in multiple devices. The fact that it costs less than the Lexar 2000X series and the SanDisk 1866X series is just icing on a cake made entirely of icing!
In the end there really is not much to dislike about this series and the only scenario where it may be a touch less than optimal is in sustained heavy usage situations. Here the smaller form-factor means the card is not as capable to dump excess heat away from the NAND, and the entirely plastic adapter is equally less than ideal at being a heatsink. Though to be fair the scenarios and situations where this will be an issue are slim to say the least; however, with a lifetime warranty even here there is not much down side to choosing this micro-SD card series as your ‘safe’ choice.
