512GB Industrial Grade microSD Card, U3 A2 V30 High Speed Memory Card with Adapter, Support Ultra HD 4K Video Recording

Followed the advice of other reviewers and ordered this for my new Viofo dash cam. Seems a bit pricey but I wanted to make sure I had compatible equipment installed. It works as expected.

Worked perfectly with my unit... The video & picture quality are crystal clear. I highly recommend purchasing this industrial grade micro SD card if you own a VIOFO dash cam to avoid any interruption in quality.

Came with card adapter. Works fine in my dash cam.

I bought this Industrial Grade card specifically to pair with my VIOFO dash cam. While you can use other brands, I wanted the peace of mind that comes with using the manufacturer's own card to avoid any compatibility headaches or "Card Error" messages. After using it, here is why I believe the 256GB model specifically is the best choice: 1. Compatibility & Peace of Mind Since this is from VIOFO, it is plug-and-play. It handles the high bitrate of 2K/4K recording without stuttering or dropped frames. It eliminates the guesswork of trying to find a third-party card that plays nice with the camera's firmware. 2. Why 256GB is better than 64GB/128GB Lifespan: Dash cams kill cards by constantly writing over old footage. With a larger 256GB card, the "loop" takes longer to complete, meaning each memory sector gets written to less frequently. This significantly prolongs the card's life. Buffer Time: If you are running a 2-channel (Front/Rear) or 3-channel setup, a small card fills up in hours. This 256GB gives you plenty of buffer time before footage gets overwritten. 3. Why I chose this over 512GB Stability: You might be tempted to get the massive 512GB card, but in my experience, many dash cams struggle with the file systems on cards that large, leading to errors or skipped frames. The 256GB is the current "stability sweet spot"—it offers maximum storage without the compatibility risks of the 512GB cards. Maintenance Tip: Just remember to format the card inside the camera immediately before using it. I also recommend formatting it once a month to keep the file system clean and ensure it lasts for years. Verdict: This is the perfect balance of size, stability, and compatibility. Highly recommended for any VIOFO setup.

Expensive, but specs seem to be on the mark and hopefully means I don't have to worry about the SD card failing on me when I need it most. I'm planning on grabbing 2-3 more so I have some to swap around just to guarantee they stay as reliable as possible. Easy to put in the camera, doesn't change camera quality at all, and works with other dashcams if I ever upgrade

I purchased this VIOFO 128GB Industrial Grade microSD Card for my new VIOFO dash cam. It captures great video quality, has plenty of storage capacity and doesn't miss a beat. The camera over writes previous video. CAUTION: It's called micro for a reason. It's tiny. Smaller than a dime. If I need to download a video, I unplug the power cable from the camera and then remove the micro SD card while holding it over a table or desk. If I were to fumble around inside the card trying to remove the card and drop it, who knows if I'd ever find it!

Very reliable and good value.

Use this on my VIOFO Dash cam because I thought I needed it because they function did not work. To find out that the function did not work because that's the way it was designed. NOT gonna say it was a waste of money as it is a very good card, But really didn't need to buy it.

I tried a non 'industrial grade' card from SanDisk and it was very hit-and-miss on whether my Viofo dashcams recorded to it or to the SSD I preferred to use; the camera did not operate in a stable way. Then I found this Viofo-branded and recommended card that was far cheaper on Amazon than it was direct from Viofo and even cheaper than the SanDisk card. Result: stable camera operation and reliable recording to the SSD as I specified, with the Viofo card as a drive if I wished and also carrying the system software. I had similar issues with cables and realised that the best action was to use Viofo's accessories with its camera systems. This card is good value for money and ensures that these great dashcams work perfectly.

Excellent quality.

Good memory card. Works well with the dash cam.
