Why We Like It – Lexar 1000x

The Lexar 1000x belongs to the company’s Professional line of memory cards, which offer super fast read speeds with UHS-II technology. The memory card is great for mobile phone users, photographers, videographers, and other devices. It can be used to record/store full HD, 3D, and 4K videos, as well as high-quality photos. If you’re not sold by this card, for ultra-important data this SanDisk Write-Once memory card lasts 100 years. 

  • Super fast read speeds of up to 150MB/s
  • Can record/store 4K UHD content
  • Backwards compatible with UHS-I devices
  • Average write speeds


The Lexar 1000x is a UHS-II memory card that can provide a read speed of up to 150MB/s. This makes it a great card when compared to UHS-I cards such as the Sandisk Extreme Pro. The card offers slightly slower write speed of around 60MB/s, however, it is plenty fast for writing 4K videos. The high capacity storage also makes it a great card for smartphones, and tablets. This UHS-II card is better than the SanDisk Ultra 256GB MicroSDXC UHS-I Memory card in terms of performance, especially when used with the provided card reader.


Although all SD cards look the same in terms of design, manufacturers like to use different colours to make the cards look good. The Lexar 1000x is a great looking SDXC memory card that uses White/Gold colours with Black/White prints for text. However, if you’re looking for a card that has more pop, then the Samsung 128GB Micro SD is for you. The Lexar UHS-II memory card weighs in at just 13 grams and 0.4-inches thick.


The Lexar 1000x is complete value for money considering the UHS-II support and super fast read speed of 150MB/s. There aren’t many UHS-II cards available online that are both powerful and have a good design. It also features a lifetime limited warranty, which is more than other cards, such as the Sandisk Extreme Pro. For those who want a 64GB storage card, the Silicon Power MicroSD Card is a great option that’s available on Amazon or B&H. Lexar also bundles a fast USB 3 adapter with the card.

Lexar 1000x Wrap Up

The Lexar 1000x is meant for the professionals, thanks to the UHS-II technology, 150MB/s read speeds, and its ability to record full HD video, 4K, as well as 3D content. It is also backwards compatible with UHS-I devices, which is great since most products don’t support the faster UHS-II standard. The write speed could’ve been faster, but is good enough for most users.
