New Lexar microSD card might be too fast for its own good

This week, Lexar revealed a new line of microSD memory cards, the Lexar Professional 1066x microSDHC/microSDXC Silver Series. These cards sport read and write speeds of 120 MB/s and 160 MB/s respectively. However, can the card actually utilize these speeds?

The new cards are UHS-I. UHS-I cards, as described by the SD association, are only able to hit up to 104 MB/s at their highest output. The common card format most videographers use is UHS-II. This format has a minimum speed of 156 MB/s. So, the Lexar Professional 1066x microSDHC/microSDXC Silver Series is promising read and write speeds of 120 MB/s and 160 MB/s, yet is in the UHS-I format. So, according to the company, the cards will be able to outperform the UHS-I format rating given by the SD association.


The Lexar microSD cards are designed for action cameras, drones and Android smartphones. These cards, according to Lexar, are capable of transferring Full-HD and 4K UHD video at 160MB/s read and 120MB/s write. Additionally, the card is U3, V30 and A2 rated and is Class 10, UHS Speed Class 3 (U3) and Video Speed Class 30 (V30). This means the cards should allow shooters to shoot faster and longer.

“As action cameras, drones and smartphones become more essential for content creators, it’s our goal at Lexar to continue creating solutions that customers demand in order to create high-quality images and stunning 4K video. And with high-capacity options up to 512GB, users can rest assured they will have sufficient space to capture what they love most,” said Joel Boquiren, General Manager of Lexar.

  • Full-HD and 4K UHD2 with write speeds up to 120MB/s
  • A2 speed
  • Capacity: up to 512GB
