MicroSD
We use MicroSD memory cards on a daily basis in smartphones, tablets, cameras, cameras, laptops, UAVs, etc. The advanced audience of users knows that the more productive the device in which it is planned to use MicroSD, the higher its write speed (MB / sec) should be.
This parameter is predetermined by the following speed classes:
- Class 2
- Class 4
- Class 6
- Class 10
- UHS Speed Class 1 (U1)
- UHS Speed Class 3 (U3)
- V6
- V10
- V30
- V60
- V90
There is also another equally important parameter that you need to pay attention to when choosing - this is the read speed (MB / sec). The higher its value, the faster you can transfer the recorded information from the card to any other external storage device (device).
In order to protect the consumer from problems associated with the incorrect choice of memory cards, almost all manufacturers of electronic products, in particular drones in the specification indicate a list of recommended cards indicating required performance.
If there is no such information, then in general, knowing the write speed and read speed, the consumer can already make the optimal choice for himself. But, as practice shows, only a rare drive manufacturer reflects accurate data in the specification. This is what the popular youtube vlogger and host of the Tom’s Tech Time channel, Tom David, told about. For those arriving in search of MicroSD cards, he offers a comprehensive comparative analysis of the ten most popular cards today.
Before comparing the drives, Tom collected their main characteristics, which were indicated by the manufacturers in the specifications. He then measured the performance of each with a USB 3.0 card reader and Crystaldiskmark software. To measure the write speed and read speed, a 4.1 GB video file was taken.
Result
Tom's comparative analysis provided comprehensive information, based on which a practical choice can be made for devices with any performance. By the author's own admission, out of all the presented cards, he prefers TOSHIBA EXCERIA PRO, he recommends it to anyone looking for a safe, compact and fast way to store data.
Conclusion
Based on the presented video material, the following conclusion can be drawn. For those looking for a MicroSD for 4K video recording, the first four places will be optimal: SanDisk Extreme Pro; TOSHIBA EXCERIA PRO; Samsung PRO and Verbatim. At the same time, we hasten to note that in view of the fact that Internet trading platforms are simply overflowing with carriers of this type, the danger of getting counterfeit goods is very high. Buy only from trusted sellers recommended by the manufacturers themselves. Remember, the miser pays twice! And if you have allowed yourself to purchase a high-tech drone, make sure that all related products for it are of the same level, both in terms of technology and quality. This approach will allow you to avoid many troubles.
