Drones now have rapid technological developments and prices have gradually become closer to the people. Therefore, many consumers have begun to purchase their own personal equipment. The drones are no longer necessary equipment for professional high-end aerialists. With continuous improvement, many drones can support 4K ultra-clear quality shooting.
UAVs have obvious advantages over traditional photography and can give users a totally different perspective experience. This is why more and more people are joining the consumer drones, but the so-called good horses. With a saddle, how can a little drone with a force to a memory card to record your shooting moment?
Today, the author came to pass a Hengping to teach you to choose the most suitable drone memory card!
Today we’re here to bring you three horizontal reviews of TF card products. First of all, I’ll first introduce you to these three memory cards. They are Samsung EVO Plus upgraded version + 128GB memory card, Toshiba M303 EXCERIA 128G and Flash Di A1 high-speed supreme 128G memory card.
First look at the basic data of each memory card:
As the support of these three memory cards is resistant to high and low temperature, waterproof, X-ray resistance and impact resistance, the focus of our cross-review will be on the performance of the three types of memory cards. Here is what we will introduce to you. The actual performance of these three memory cards.
Theory of reading and writing tests: CrystalDiskMark
In theoretical reading and writing tests, we use the more popular CrystalDiskMark and ATTO in the storage industry for actual measurement.
CrystalDiskMark is an easy-to-use hard disk performance test software, but the test project is very comprehensive, covering continuous read and write, random read and write performance of 512K and 4KB packets, and 4K random performance with a Queue Depth of 32 .
The queue depth describes the maximum IO value that the hard disk can activate at the same time. The larger the queue depth, the higher the actual performance.

From the above data, we can see that the three memory cards are almost the same in read speed. However, the Samsung EVO Plus +128GB memory card is significantly faster than the other two.
We all know that when recording video, faster writing speeds mean a stable and clearer picture quality, and in terms of the performance of reading and writing, and this helps to improve the handling of large-volume, fine-grained files on the memory card. And transmission performance, has a very good effect on video recording.
Theoretical reading and writing test: ATTO
ATTO Disk Benchmark is an easy-to-use disk transfer rate detection software that can be used to detect the read and write rates of hard disks, USB flash drives, memory cards and other removable disks.
Because the software uses different data test packets, the data packets are read and written by 0.5K, 1.0K, 2.0K up to 8192.0KB, which can simulate the working mode of SSDs and other storage tools in daily life.
Therefore, it can objectively and truly reflect the performance of SSD in real life. It has certain reference value and significance for ordinary users.
One of the innovations of this software is that after each data test is completed, the system will express it in the form of a histogram. It is concise and clear to show the effect of different file sizes on the read/write speed of the disk.

In another ATTO test that reflects the read/write performance of flash memory cards, the gap between the three is not as large as in the crystaldiskmark. However, both the Samsung EVO Plus +128GB memory card has a leading performance in reading and writing. .
