Transcend High Performance provides a fast write speed and the added benefit of an endurance card. Although it has slightly less usable storage compared to some other options, it remains a solid choice for dash cam usage. 5. SanDisk Extreme Pro Use case: Like SSD, there are broadly three types of microSD cards. One geared towards value-for-money, one geared towards performance (i.e. how fast) and one geared towards endurance (e.g. drone, dashcam, bodycam etc.). Choosing the right one for your needs will determine your overall experience. Class 1 (A1) Application Performance Class also called SD Physical 5.1 spec, with a write speed of 10Mbytes/sec and minimum random read of 1500 IOPS (Input/Output Operations Per Second) and random write of 500 IOPS. IOPS is used because it’s a useful way of measuring the speed of the kind of computing operations that applications undertake, as opposed to simply reading or writing a large file.
In 2017, a faster UHS-III was released, which further improved the performance of the data bus, and in 2018, the SD Association announced the SD Express specification – this version uses up to 2 PCI Express lanes to provide a huge increase in throughput. SD Card Bus Speeds Bus system A high-quality micro SD card is crucial for your dash cam to work effectively, ensuring smooth recording and reliable storage of your footage. The next generation specification, settled in June 2018, supports cards up to 128 TiB (1 Tebibyte is 1024 GB), however it is still not in regular use yet.SDSC is restricted to FAT12, FAT16, and FAT16B. SDHC is nearly always FAT32 and the XC/HC versions use exFAT. The exFAT file format was specifically designed for NAND flash devices and is likely to remain the standard for many more years. Higher memory capacity allows for more extended periods of recording before the card becomes full. Most cards come in various sizes, typically ranging from 32 GB to 256 GB or higher. For dash cam usage, a 128 GB card is an excellent balance between storage capacity and affordability. Write Speed Secure Digital eXtended Capacity. Announced in 2009 this was version 3 of the SD specification, adopting exFAT file system and extending the theoretical storage limit to 2TB.
Yes, it’s essential to format your micro SD card before using it with your dash cam to ensure proper functionality and compatibility. How often should I replace my dash cam’s micro SD card?
Are there alternative microSD cards worth considering?
If you’re looking to grab a microSD card for your drone or other media device and need to bank big data (capacity exceeds 1TB) or perhaps need multiple decent cards, the Lexar Play is a great option. At the other end of the scale, Class 10 (10 MB/s) cards are capable of recording or playing up to 4K video, although not at a very high frame rate. The HC in SDHC stands for High Capacity, and the choice of those words is what left the industry needing XC soon after. If you’re trying to help out an older device limited to HC and U1, then the SanDisk Ultra is a good choice – as these may well warn you not to use larger than 32GB cards, due to incompatibility with more the more recent card format. (Note that the Ultra card is available in larger sizes - but with the SDXC logo which will mean it will be incompatible with these older devices). How we test microSD cards The fifth category, Secure Digital Input Output ( SDIO), are special in that they contain more than just storage. These cards sport an extra device that provides additional functions, such as a Bluetooth or GPS receiver. Because there is a big difference in the storage sizes, each category also has restrictions of the file format used. The SD Association came up with the speed classification systems to help differentiate what cards are best suited to what purposes. The simple Class number is the most immediate indicator to the speed of an SD card, with Class 2 (2 MB/s) cards being toward the bottom of the spectrum and are best geared towards less demanding tasks, such as recording standard definition video.

A microSD card is a small, portable memory card designed to store digital information such as photos, videos, and other files. It is commonly used in various devices like dash cams, smartphones, and digital cameras. Choosing the best microSD card for your dash cam is crucial for optimal performance and reliable storage of your footage. Custom made and designed products such as flash memory products with custom logo’s on them. E,g USB flash drives and memory cards with your own logo
How did we choose these best microSD cards?
There are 3 standards for the dimensions, and they are incompatible with each other. In other words, a miniSD card reader won't work with microSD cards (unless you use an adapter): A byte is 8 bits, and a bit is the smallest unit of information storage on a microSD card. That means a data transferred at 10 Megabits per second would take eight times as long as 10 MegaBytes per second.
Other than the benchmarks, we considered four factors that could help you select the perfect microSD card for your usage. SDSC, SDHC, and SDXC cards are supported in a wide range of devices, such as laptops, smartphones, drones, and digital cameras. The need for increased storage continually grows, thanks to bigger games, more complex apps, and cameras sporting ever higher resolutions – but there will always be an SD card for everyone's needs and budget. While most micro SD cards should work with your dash cam, it’s recommended to choose an endurance card designed for constant recording and overwriting to ensure optimal performance and durability. What is the ideal memory capacity for a dash cam micro SD card? For a wide majority of users, the best value cards will be fast enough and will offer plenty of storage. However, for more specialized use (when top-end performance is required), make sure you are buying a card that's right for the task, and that your device can take full advantage of the card's rating. When a microSD card (or any disk system) stores a file, it might need to split it into pieces to fit around information already on the card. Over time adding and removing files can leave a number of fragments of files which will slow down accessing the card because the device needs to move between each fragment as it reads or writes. Thoroughly deletingthe device (formatting and starting again) or using a defragmentation tool is a good solution.
Sandisk Ultra MicroSDHC
Class 2 (A2) Application Performance Class also called SD Physical 6.0 spec, with a write speed of 10Mbytes/sec and minimum random read of 4000 IOPS (Input/Output Operations Per Second) and random write of 2000 IOPS. Dash cams are essential devices that provide peace of mind and evidence in case of accidents or incidents on the road.
