SanDisk Extreme PRO microSDXC-kort 1 TB SDSQXCD-1T00-GN6MA UHS-I 200 MB/s

good quality product; used to store documents and data on a samsung smartphone

I bought these 64GB memory cards for my DJI Osmo Pocket 3, which requires high-performance cards, and I wasn't disappointed. They are capable of 120 frames per second in 4K. I'm just sorry that LDLC didn't stock 128GB and 256GB models, which would have given me around 2 hours and 4 hours of images of this quality. In their defence, it wasn't easy to find them elsewhere.

very fast microSD. Tested with a Kingston microSD/SD adaptor and Kingston Mobilelite Plus USB 3.2 UHS-II "SD" Card Reader for transferring a file of just over 6GB: I obtained a write speed of between 128 and 132 MB/s (very stable write speed), and a read speed of between 185 and 245 MB/s (faster than expected for reading at times!). For comparison, under the same conditions with a Kingston Canvas Go! Plus 512 GB 170MB/s microSD card, I got a write speed of between 86 and 99 MB/s and a read speed of between 160 and 168 MB/s (but with a big drop in the middle of copying files: speed not stable). WARNING: the 'quality' of the card reader is important: I had a write speed of around 35MB/s on another memory card reader (Goobay USB 3.0 USB-C without using a microSD/SD adapter) and around 85MB/s on a Lexar 'microSD' UHS-II USB 3.0 card reader.

Bought 2 Micro SDXC 64GB for my DJI Action 3. Work perfectly after 1 year, no slowdowns, no writing problems with the speed of the videos even in 4K120. As usual, no problems with SanDisk.

What can I say about an SD card... It's in the long term and the durability that it shows. On the other hand, I use this card on an Insta360 X2. Recording in 360° 4k goes very well.
