VIOFO 256GB Industrial Grade microSD Card – Extended Capacity for Serious Dash Cam Use
Standard consumer microSD cards weren’t designed for the relentless write cycles of a dash cam recording 24/7. Cheap cards are by far the most common cause of “memory error”, missing footage and unexplained recording dropouts. The VIOFO 256GB Industrial Grade microSD card is purpose-built to handle continuous loop recording, parking-mode surveillance and high-bitrate 4K capture — so the footage is actually there when you need it. The 256 GB capacity is the sweet spot for multi-channel dash cams (front + rear, or front + rear + cabin) and for drivers who want longer rolling coverage before the loop overwrites.
Why an industrial-grade card matters
- High-endurance NAND — engineered for write-intensive applications like dash cams, body cams and surveillance systems.
- U3 / A2 / V30 rated — sustained write performance for 4K, Ultra HD and high-bitrate recording without dropped frames.
- Read speeds up to 100 MB/s, write speeds up to 80 MB/s — fast offload of clips to your phone or PC.
- Optimised for VIOFO dash cams — full compatibility with the A329S, A229 Pro, A229 Plus, A229 Ultra, A329T, A119M Pro, VS1, A119 Mini 2 and the rest of the VIOFO range.
- Operating range -25°C to +85°C — designed for the hot dashboard in summer and a frosty Canterbury morning in winter.
- Waterproof, X-ray proof, anti-magnetic, shock-resistant — survives the conditions a card in a vehicle actually faces.
- SD adapter included — drop it into any standard SD card reader to pull footage off on your laptop.
How much footage will 256 GB hold?
Recording time depends on resolution and bitrate. Approximate continuous recording times on a 256 GB card with common VIOFO models:
| Dash Cam Model | Resolution | Approx. recording time (256 GB) |
|---|---|---|
| A119M Pro | 4K 30fps (High) | ~14 h 23 min |
| A119 Mini 2 / VS1 | 2K 30fps | ~17 h 20 min |
| A229 Plus 2CH | 2K + 2K (High) | ~11 h 12 min |
| A229 Pro 2CH | 4K + 2K (High) | ~9 h 20 min |
| A229 Pro 3CH | 4K + 2K + 1080p (High) | ~7 h 28 min |
| A329S 2CH | 4K 60fps + 2K (High) | ~6 h 56 min |
| A329S 3CH | 4K + 2K + 2K (High) | ~5 h 20 min |
Once the card is full your VIOFO dashcam loops over the oldest footage automatically, so this is rolling coverage — not total storage before it stops recording. Locked event files (impacts, manual saves) are preserved separately.
Is 256 GB the right capacity for me?
For most single-channel dash cams, 128 GB is plenty for everyday driving. Step up to 256 GB if any of the following apply:
- You’re running a 2-channel or 3-channel setup (front + rear, or front + rear + cabin) where the same card stores multiple video streams.
- You record in 4K at the highest bitrate and want more than a few hours of rolling footage.
- You use parking mode heavily and want longer overnight coverage.
- You drive long-haul, rideshare or commercial routes where overwriting too quickly is a real risk after an incident.

Format it on first use
Whichever microSD card you use, we strongly recommend formatting it inside the dashcam (Settings → Format SD Card) on first install, and reformatting every 4–6 weeks. This keeps the file system clean and prevents the “memory error” or “memory full” warnings that plague cards left to fill up indefinitely.
