  • QuestionWill this chip work well with the Garmin Dash Cam X110?

    Asked by Brad.

    • Answer Hi Brad, thank you for reaching out to us. The SanDisk microSD Express card may not work with the Garmin Dash Cam X110, as the camera supports standard UHS-I microSD cards only. For best performance and reliability, we recommend using a high-endurance card like the SanDisk High Endurance or SanDisk Extreme microSD UHS-I card, which are designed for continuous recording in dash cams.

      Answered by SanDisk Team

  • QuestionDoes this card work with Vantrue 4 Pro dash cam

    Asked by Sarge.

    • Answer Hi Sarge, please know that the SanDisk Express 512GB microSD card can technically work in the Vantrue 4 Pro since the camera supports UHS-I cards, but it will only run at standard UHS-I speeds and not its full Express performance. However, for dash cams, we recommend using a SanDisk High Endurance or Max Endurance card, as these are designed for continuous recording and offer better reliability than non-endurance cards.

      Answered by Boldly

  • QuestionCan I use this for a go pro or insta 360 x5

    Asked by Cameradude.

    • Answer Hi, thanks for contacting us. The SanDisk Express microSD works with devices that have a microSDXC slot, including Android phones, tablets, action cams, drones, handheld gaming devices, and laptops. It’s also compatible with microSD Express UHS-I and UHS-II slots, performing at UHS-I speeds in those devices. For GoPro or Insta360, it should work if the camera supports microSDXC. But, we still suggest referring to the host device specifications and manufacturer support.
