Recently, ADATA introduced its first microSDXC with 256GB capacity. The card is based on 3D MLC NAND flash memory from SK Hynix.
As you can see from the table, the UHS-II bus is rated at up to 275 MB/s read speed and up to 260 MB/s write speed. That means that it is suitable for recording 4K UHD (3840 x 2160p) and 360° videos. The microSD card is also labeled as Class 10, U3 and V90 which means that speeds can’t drop below 90 MB/s so you can even capture 8K (7680 × 4320p) video on it. The MLC (multi-level cell) flash memory technology used is the best compromise between write cycles, speed, and cost. However, due to the big capacity, we should expect a serious price tag.
We are expecting the new product to arrive at our office for testing soon. We will try to share the results with you as soon as possible.
