Lexar Professional 1800x microSDXC UHS-II (64GB) Review


Testing the Lexar 1800x microSDXC proved to be more interesting than we expected. Unfortunately, at no point in time did we see this card exceed or for that matter come near the listed specifications. We did, however. see very close results in crystal disk mark and anvil storage utilities, which proves that this microSDXC card is a solid performer. We attempted to test this microSDXC card in various microSD card adapters, but none of which seemed to provide as high of results as the supplied USB adapter.

Let’s bring this back for a second, this microSDXC card is designed for media professionals who need quick transfer from their smaller devices (i.e., drone cameras, action cameras and smartphones). When we look at the test results as a whole, the average throughput is still quite impressive for a microSDXC card, and that is without considering the available capacities.

While we would have liked to have seen more consistent performance from the Lexar microSDXC card, it is still a high quality card that would excellently serve its purpose in your drone’s camera or your action camera. For these reasons, we award the Lexar 1800x microSDXC card with our Bronze Seal of Approval!

  1. most cameras and other dont have UHS-II support. it requires extra interface, so the card is limited to UHS-I in moost appication and this is limited to about 100mb/s .You should rather test this cared against other in high end camera not in windows stupid tools

  2. Woah, those are some pretty expensive cards.

    I wish manufacturers would make cards, tuned for random performance. With lots of single board computers floating around without any nand storage, cards like this would be great.

    Instead of crazy 100MB/s+ sequential speed, tune the card for low QD at the expense of sequential performance. i’m sure it can be done.
