VIOFO 256GB Industrial microSD Card - U3 V30 A2, 120,000-Hour Endurance

The Size Most Drivers Should Buy. VIOFO 256GB industrial microSD, rated for 120,000 hours of recording

Cheap cards fail in dash cams for one reason: the camera never stops writing. Fill, overwrite, repeat, every second the engine runs. This is an industrial-grade card built for exactly that duty cycle and rated to 120,000 hours, and at 256GB it holds enough history that you are not racing the loop when you go looking for a clip. For a front-and-rear setup, 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 you run a 3-channel rig, a fleet vehicle, or long parked sessions, 256GB will cycle faster than you would like and the 512GB is the better buy. If you only record front on a short commute, the 128GB will do the job.

DCG Score & Highlights

What We Love

• Endurance rated to 120,000 hours of continuous recording
• Certified from -25 °C to 85 °C, which covers a parked car in an Australian summer
• 256GB is the sweet spot for 1-channel and 2-channel setups
• U3 V30 A2 with up to 100 MB/s reads for quick transfers
• Waterproof, anti-X-ray and anti-magnetic build
• Full-size SD adapter in the box

What Could Be Better

• It costs more than a consumer card of the same size, which is the point but still worth saying.
• A 3-channel camera will fill it faster than you expect, so size up if you run three lenses.
• It is built for dash cam duty rather than general-purpose use, so look elsewhere for a camera or drone card.

Why Industrial-Grade Storage Outlasts Consumer Cards

Consumer cards are specified for occasional writes. A dash cam does the opposite, rewriting the same blocks continuously for years, which is why cards that work fine in a phone throw errors after a few months in a car. Industrial-grade flash and controllers are designed for that duty cycle, and are rated in hours of recording rather than transfer speed.

Top Benefits

• Survives the duty cycle: 120,000 hours of continuous recording, not a consumer write rating.
• Handles Australian heat: Certified to 85 °C, which a parked cabin genuinely reaches.
• Right-sized history: Enough capacity that everyday driving does not overwrite what matters.
• Fast retrieval: Up to 100 MB/s reads for pulling evidence onto a laptop.
• Protected build: Waterproof, X-ray and magnet resistant.
