This 256GB EVO UHS-I microSDXC Memory Card from Samsung holds 256GB of data. Its Ultra High-Speed Class 1 (UHS-I) bus interface enables it to achieve maximum read and write speeds of 100 MB/s and 30 MB/s respectively, which are far greater than the 10 MB/s minimum speeds guaranteed by the Class 10 and UHS-I ratings. This microSDXC card is ideal for Full HD video recordings and high-resolution pictures. A microSD to SD adapter is included, allowing you to use the card in a full-size SDHC/SDXC slot.
The EVO series is waterproof (lasting up to 72 hours in seawater), magnet-proof, and X-ray-proof. Additionally, it is capable of withstanding temperatures of -13 to 185°F. Protection is provided by a limited 10-year warranty. Please note that the warranty is not valid when this memory card is used in dashcams, CCTV, surveillance cameras, and other write-intensive devices.
