Nextbase U3 Micro SD cards are the perfect storage solution for your new Nextbase dashcam! SD cards are available in six different speed classes, from slowest to fastest: Class 2, Class 4, Class 6, Class 10, U1, and finally U3. U1 and U3 refer to the write speeds of the cards. U1 has a write speed of up to 10MB/s and U3 has a write speed of up to 30MB/s, making U3 ideal for 4K video and RAW images shot in high-speed burst mode. Don't compromise on your storage media! We only sell the best memory cards with our dash cams and this is no exception.

Nextbase memory cards are industrial-grade and are designed to withstand the extreme temperatures found inside of modern automobiles, as well as endure the constant read/write cycles of full high-definition or 4K dash cams.

Compatible with every dashcam sold at The Dashcam Store™, particularly all Nextbase models. Please note only the Nextbase 622GW can accept the 256GB card. All other models (122/222/322/422/522) are limited to 128GB.

Includes a free microSD to SD adapter!
