Lexar Professional 1000x originally reads data at a speed of 150MB/s. When we tested it further, we noticed that it passes this speed and reaches a speed of 152MB/s on many UHS-II card readers. It is important to keep in mind that this memory card is compatible with UHS-I card reader as well as UHS-II card readers. However, only the UHS-II can unlock the highest speed of the card. With a write speed of up to 50MB/s, this memory card is the best for easy and quick data transfer.

Summary

We’ve already seen valuable reasons why SanDisk and Lexar Professional are the best memory cards for the money. Most importantly, though, the primary reason why SanDisk and Lexar memory cards compete so well with cheap related products is that these products have been approved for both workflow and efficacy. The compatibility of these memory cards with multiple HD cameras and digital camcorders make them the best memory cards to buy in 2017.
