What about the large capacity of the driving recorder memory card?

There are three common memory cards on the market, namely: SD card, TF card (Micro SD card), CF express card

SD card：

SD cards are the most common, and most cameras and card machines use SD cards.

The biggest feature of the SD card is that it has a write protection switch. The files on the SD card can only be read, but not written. When the switch is turned up, the protection state is released, and files can be written and copied.

TF card

TF cards are used in many scenarios, such as: drones, action cameras, panoramic cameras, etc., and the car's driving recorder is also a TF card.

CF express card

CF express cards are rare, only supported by some high-end mirrorless cameras, and their transfer speed and performance are the strongest.

In addition, CF express cards are divided into three types, TypeA, TypeB, and TypeC. Currently, the commonly used CF express cards on the market are B-type cards.

Parameters on the memory card

Because the SD card is the most representative, I took the SD card and made a picture:

Memory card capacity

The largest number marked on the memory card is the memory card capacity, usually 32GB, 64GB, 128GB, 256GB, 512GB, etc.

My personal suggestion is to choose 32GB or above as much as possible. If you often shoot videos or time-lapse photography, etc., it is best to choose 128GB or above.

Read and write speed

The memory card has two speeds of reading and writing. Generally speaking, the reading speed is greater than the writing speed, so the digital patterns such as "170MB/S, 150MB/S" on the memory card indicate the reading speed.

Speed class

There is a "3" in the word "U", which means "UHS speed grade", U1 means the minimum continuous writing speed is 10MB/s, and U3 means the minimum continuous writing speed is 30MB/s.

The number in "C" indicates the speed level, which is the earliest speed level established. There are five levels: C2, C4, C6, C8, and C10.

Now basically no one looks at the C mark anymore, and basically everyone looks at the U mark.

Video speed class

The sign of "V+number" is the video speed grade, and there are five common grades: V6, V10, V30, V60, and V90.

V6 indicates a minimum sustained speed of 6MB/s

V10 indicates a minimum sustained speed of 10MB/s

V30 means the minimum sustained speed is 30MB/s

.........

But not all memory cards have this logo. If you shoot a lot of videos, then this logo must be there.

When buying a memory card, you must first check which type of card your camera supports. In the camera parameter column, where the storage medium will be clearly marked which type of memory card the camera supports and the camera manual will also be clearly marked.

Speaking of memory cards, in my initial impression, it is the amount of songs stored in MP4 or the memory card of the mobile phone. I remember that when I first contacted the memory card, the memory was 4GB, 8GB, and the maximum was 16GB, and the price was not cheap. Nowadays, most people have also bought private cars, and almost all of them have installed a driving recorder to reduce the worries of driving, and the memory card, as the core component of the driving recorder, has not left our lives, and how to choose a cost-effective one The memory card has become the key to our selection of driving recorders. So in the face of many brands and different types of driving recorder memory cards on the market, how should car owners choose, and how big should they choose? Is the bigger the better?

First of all, Brand

It looks like a small memory card, but in fact it hides a lot of black technology, and most of the companies that can really independently develop and manufacture are some well-known large enterprises. After all, market opportunities and market risks coexist.

After years of development, the current price of memory cards has been relatively stable. Under the circumstance that the price is comparable, choosing an international big-name memory card is undoubtedly more secure for the stability and safety of the driving recorder. Professional-grade high-endurance memory cards are produced by Xinghengguang, the world's largest supplier of flash data memory cards. It has a huge user base around the world, and the size and market share of users are the source of brand reputation and confidence.

What exactly is durability?

I believe all car owners know that if the car is parked under the sun at noon on a hot summer day, the temperature inside the car will soar. Is it high temperature? The durability that professional-grade high-endurance memory cards particularly emphasize can be simply understood as: the harshness/harshness of the working environment that can be adapted and the number of times the memory card can be repeatedly erased and written. It has the ability to cope with harsh environments. Whether it is temperature resistance, waterproof, shockproof, anti-x-ray, it can deal with the advantages, no fear of severe winter or extreme summer. The allowable repeated erasing times is the number of times the memory card memory is full and then erased, which can also be converted into the total amount of writing. The new Xinghengguang professional high-endurance memory card is specially optimized for the number of erasing times. Officially announced as 128GB Taking the capacity version as an example, the actual saved video is about 60,000 hours (if it is full HD video or 4K UHD video, the total hours will be slightly less). Xinghengguang professional-grade high-endurance memory card has ultra-high durability performance and continuous stability, long-term stable support for 4K video recording, worry-free recording of high-definition pictures, and capture every driving detail.

Second, bigger capacity is not means better!

Like the mobile phone, the recorder has a support for maximum expansion memory. If the memory is too large, it will be impossible to write data and affect the stability of work. Therefore, when choosing a memory card, you must understand your recorder and usage habits. Moreover, the recorder will automatically overwrite the content during recording, so the read/write speed and the number of read/write times of the memory card, that is, the life span, also need to be fully considered, don't think about it once and for all.

Xinghengguang professional high-endurance memory card with large capacity and long-term durability. It is available in various capacity specifications, including 32GB (15,000 hours of life about 1.7 years), 64GB (30,000 hours of life about 3.4 years), 128GB (60,000 hours of life about 6.8 years), and up to 256GB (120,000 hours of life about 13.6 years). It is recommended to use 32GB-128GB for the car, and it can record repeatedly for 1.7 years to 6.8 years, and according to different capacity versions, it provides an effective warranty period of 3 to 15 years; fast backup, fast transmission speed. Xinghengguang professional-grade high-endurance memory cards have a read speed of up to 100MB/s (write speed of up to 40MB/s) for fast video transfer.

At present, most of the driving recorders support up to 32GB memory cards, and some also support 64GB or even 128GB. Xinghengguang professional-grade high-durability memory cards have corresponding capacities. In addition to driving recorders, home monitoring equipment can choose a higher-capacity 256GB professional-grade high-durability memory card to meet more needs and achieve long-term, clear and fast recording of every moment of life.
