Drones are now developing rapidly in technology, and prices have gradually become close to the people, so many consumers have begun to buy for their own use, so that drones are no longer necessary equipment for professional high-end aerialists. With continuous improvement, many drones can support 4K ultra-clear image quality shooting.
Drones have obvious advantages over traditional photography, and can bring users a completely different perspective experience, which is why more and more people are joining the consumer drone industry, but the so-called good horse With a saddle, how can a powerful drone get a powerful memory card to record your shooting moments?
Today I will teach you to choose the most suitable drone memory card through a horizontal review!
Today we will bring you a cross-review of three TF card products. First, let me introduce you to these three memory cards. They are Samsung EVOPlus upgraded version + 128GB memory card, Toshiba M303EXCERIA128G and SanDisk A1. High-speed Extreme 128G memory card.
First look at the basic data of each memory card:
Since these three memory cards support high and low temperature resistance, waterproof, anti-X-ray and impact resistance, this time our focus will be on the performance of the three memory cards. The following is our introduction. The actual performance of these three memory cards.
Theoretical reading and writing test: CrystalDiskMark
In the theoretical reading and writing test, we use CrystalDiskMark and ATTO, which are more popular in the storage industry, for actual measurement.
CrystalDiskMark is a simple and easy-to-use hard disk performance test software, but the test items are very comprehensive, covering continuous read and write, random read and write performance of 512K and 4KB data packets, and 4K random performance when the queue depth (QueueDepth) is 32.
Queue depth describes the maximum IO value that the hard disk can activate at the same time. The greater the queue depth, the higher the actual performance.

↑↑↑ SanDisk Extreme High Speed ​​Memory Card Data
Through the above data, we can see that the three memory cards are similar in reading speed. However, the Samsung EVOPlus upgraded version + 128GB memory card is significantly ahead of the other two in writing speed.
We all know that when recording video, faster writing speed means stable and higher-definition picture quality, and in the performance of reading and writing, and this helps to improve the processing of memory cards for large batches of fine files And the transmission performance has a very good effect on the video recording.
Theoretical reading and writing test: ATTO
ATTODiskBenchmark is a simple and easy-to-use disk transfer rate detection software that can be used to detect the read and write rates of hard disks, U disks, memory cards, and other removable disks.
Because the software uses different sizes of data test packets, the data packets are read and written according to 0.5K, 1.0K, 2.0K up to 8192.0KB respectively, which can truly simulate the working mode of storage tools such as solid state drives in daily life.
Therefore, it can objectively and truly reflect the performance of the solid-state hard disk in real life, and has certain reference value and significance for ordinary users.
Another innovation of this software is that after each data test is completed, the system will be expressed in the form of a histogram, which succinctly shows the effect of files with different size ratios on disk read and write speed.

In another ATTO test that reflects the read and write performance of flash memory cards, the gap between the three is not as large as in crystaldiskmark, but whether it is Samsung EVOPlus upgraded version + 128GB memory card has leading performance in reading or writing.
Louder Bluetooth speaker is very popular with Europe and America people due to simple and applicable appearance design,
Our as sociated factories cover an area of 1900square meter s and produc tion capacity 100000 pcs per month, We are devoting on the resear ch and development moldingand production. We have experienced and efficient employees to make our private model in excellent conditions.
The wireless bluetooth speaker supports the function bluetooth player/U disk/TF card/auxiliary player/hands-free call.
TWS can be connected in series. After the two wireless speaker are turned on, press one of Bluetooth speaker the[ M "button and hold for 3 seconds. The two speaker will be automatically paired, and then search for Bluetooth to connect to from phone.
The hands-free call Bluetooth speaker allows you to not miss any calls when listening to music, and can be used outdoors, family gatherings, parties, etc.
The louder Bluetooth speaker can support maximum to 40W speaker subwoofer, and the sound is very shocking. Equipped with a nylon and leather strap, it can be carried with you or cross-body, it is very convenient to carry out, and the use of waterproof fabric, the highest IPX6 level, so you have no worry when traveling outdoors.
