Built with 3D NAND flash, it reaches read speeds of up to 160 MB/s and write speeds of up to 125 MB/s, which allows you to transfer large files quickly. Its V30 and U3 ratings ensure the sustained performance necessary for recording 4K video without interruptions, while the A2 application performance class makes it a great choice for running apps directly from the card on a smartphone or tablet. Measuring just 11 mm by 15 mm and weighing a mere 0.4 g, this compact card is built to withstand harsh environments. It is waterproof, shockproof, and resistant to X-rays, static, and temperatures ranging from -25°C to 85°C, meaning your data stays safe whether you are filming in the rain or traveling through airport security. To get the most out of the card, it comes with a microSD to SD adapter and is supported by RecoveRx data recovery software and the SD SMART Toolbox. You can achieve the maximum rated speeds when using the Transcend HUB5C card reader with the latest firmware.
