About the Viofo 64GB-SD
From our tech experts at CEN
This is a high-endurance 64GB microSD card rated U3, A2 and V30, built for the constant overwriting a dash cam does. Ordinary cards are designed for occasional photos and fail within months in a camera that writes continuously, usually without warning.
Which size do I need?
A dash cam never stops writing, so the card size decides how far back your footage goes before it loops over itself. As a rule of thumb:
- 64GB — a single 1080p or 2K camera, roughly a few hours of loop
- 128GB — one 4K camera, or a 2-channel 2K setup like the A229 Plus
- 256GB — 2 and 3-channel systems, and 4K at 60fps such as the A329S
- 512GB — 4-channel systems, full-shift taxi and private hire work, and fleet vehicles
Buy a size up if you use parking mode, since the camera keeps writing while you are away from the car, or if you only check footage every week or two.
Our tech experts advise
64GB suits a single 1080p or 2K camera used for commuting. If you run a 4K camera, a second channel or parking mode, start at 128GB instead. Format the card in the camera when you fit it and again every few months. See all VIOFO accessories.
