Review on 📷 256GB Micro SD Card by Amplim | New 2021 MicroSD Memory Plus Adapter | Extreme High Speed 170MB/S A2 MicroSDXC U3 Class 10 V30 UHS-I | Nintendo-Switch, GoPro Hero, Surface, Phone, Camera Cam, Tablet Compatible by Marc Gallner

The Amplim 256GB Micro SD memory card is fast and reliable and works with any device that requires a microSDXC or SD memory card. When you shoot video, especially 4K, you need a microSD card that can write large amounts of data quickly, and that's exactly what Amplim's 256GB micro SD card does. It has a U3/V30 rating and a write speed of 100MB/s. Amplim's 256GB micro SD card was able to achieve a write speed of 97.6MB/s on Windows 10 and maintained a steady speed of 85.4MB/s. It took less than 3 minutes to write 15GB of data. Depending on the device used, the USB transfer speed varies significantly. If you insert this SD card into a USB 2.0 port, slot or card reader, you will not get more than 40 MB. /s. So make sure you are using USB 3.0 or higher. The same applies to other devices such as smartphones and tablets. I couldn't get past 46MB/s write speed on the Moto E (2020), but it almost doubled the speed on the Galaxy S10e (2019). Since there are a lot of fake SD cards and USB devices on Revain, I usually fill them up to 100% capacity. Amplim's 256GB micro SD card was able to maintain a write speed of 97.6MB/s even when it was 95% full. We have a similarly priced V30 SD card, but it could only achieve a write speed of 87MB/s. This is a great map for action cameras, drones, photographers, and handheld game consoles.
