There are numerous differences between Nextbase industrial standard (U3) SD cards and conventional SD cards, and these are especially important when used in dashcams:
Firstly, U3 SD cards can withstand extreme temperatures (-20 to +45 degrees Celsius), which can occur in vehicles in winter or summer. SD cards without this standard can stop working at temperatures as low as 30 degrees Celsius.
SD cards in dashcams are also subject to continuous (over)writing of data, unlike those used in photo cameras, for example. Nextbase's microSDXC card is a U3 ultra-high-speed card that ensures video data is continuously written/overwritten without a problem, allowing the dashcam to record the road ahead in full HD at 1440p or 4K quality. With the microSD to SD adapter included in the package, you can easily view the files on your laptop or PC.
With a capacity of 256 GB, the microSD card can record approximately 37.7 hours* of HD footage before the dashcam overwrites the oldest recordings, or 26 hours* when using a rear camera module. This gives you enough capacity to record any incident and ensure you have the evidence you need.
The continuous read and write speeds of Nextbase U3 SD cards are also significantly higher than conventional versions according to industrial standards. When used in dashcams, a continuous write speed of at least 48 MB/s is necessary - especially for 4K recordings or with connected rear camera modules. However, most conventional SD cards without U3 standard only achieve a continuous write speed of 40 MB/s, which is too low for use in dashcams. Unlike many other manufacturers, Nextbase provides a warranty claim for all Nextbase U3 SD cards for use in dashcams. Please note that this 256GB card is only compatible with the 522GW, 622GW, Piqo 2K Dash Cams and Nextbase iQ Smart Dash Cam models.
*Recording time varies depending on model, resolution and FPS.
