The Transcend microSDXC 340S is a high-capacity storage solution with 512 GB of space, designed to handle demanding data tasks in mobile devices and cameras. Utilizing 3D NAND flash technology and a UHS-I interface, it reaches sequential read speeds of up to 160 MB/s and write speeds of up to 125 MB/s, which helps you transfer large files quickly. Its V30 and U3 classifications ensure the stable performance needed for recording high-resolution video without interruptions. Because it carries an A2 application performance rating, this card is particularly well-suited for running apps directly from the storage, supported by random read and write speeds of at least 4,000 and 2,000 IOPS respectively. The physical build is remarkably compact, weighing only 0.4 g, yet it is engineered to be waterproof, shockproof, and resistant to X-rays, static, and extreme temperatures ranging from -25°C to 85°C. This makes it a reliable choice for outdoor enthusiasts or professionals working in harsh environments. Each package includes the 512 GB microSDXC card and a microSD to SD adapter for easier use across different hardware.
