Vantrue 256GB High Endurance microSD Card – U3 V30, 4K Dash Cam Storage

The Size Most Drivers Should Buy. Vantrue 256GB high endurance microSD for smooth, reliable 4K

Rain lashes the windscreen, brakes slam, and the whole thing is over in four seconds. Whether that footage survives comes down to the card underneath it. The Vantrue 256GB high endurance microSD writes cleanly at speed and holds enough history that you are not racing the loop to find the clip. For most drivers running a 2-channel camera, this is the capacity that makes sense.

Trusted AU store: We're an authorised AU reseller, shipping from Melbourne within 24 hours^*. You get a 12-month warranty on this accessory, local technical support, and our 30-Day No-Worries returns.

Who This Isn't For: If your device needs UHS-II speeds or proprietary media, this is not the right card. If you run a 3-channel or 4-channel camera and want a long history, step up to the 512GB instead, since more channels fill a card considerably faster.

DCG Score & Highlights

What We Love

• UHS-I U3 V30 Class 10 speeds that hold up under 4K and high-bitrate 1080p
• Up to 100 MB/s read and 90 MB/s write, the same as the 512GB card
• High endurance build rated for heat, water, magnets and X-rays
• 256GB is the sweet spot for most 1-channel and 2-channel setups
• Works with all Vantrue dash cams and most other brands
• microSD to SD adapter included for quick transfers to a laptop

What Could Be Better

• It costs more than a generic microSD of the same capacity, because the endurance rating is the point.
• A 3-channel or 4-channel camera will fill 256GB faster than you would expect, so consider the 512GB for those.
• Still needs formatting in-camera every few weeks to stay reliable.

Why High Endurance Storage Matters in a Dash Cam

Footage is only useful if it was actually captured and preserved. A dash cam writes continuously, overwrites, and starts again, which is a workload ordinary phone cards were never built for. A high endurance card reduces dropped frames and file corruption through temperature swings and daily loop recording, so critical evidence is more likely to be intact when you need it.

Top Benefits

• Consistent 4K capture: U3 V30 write speeds up to 90 MB/s keep bitrates steady for clear plates and detail.
• All-weather resilience: Rated 0 °C to 70 °C in use, and resistant to water, magnets and X-rays.
• Set-and-forget capacity: 256GB gives enough history that everyday driving does not overwrite the moments that matter.
• Wide compatibility: Works with all Vantrue models and most leading dash cams and action cams.
• Easy file access: The included SD adapter makes reviewing footage on a laptop straightforward.
