The 512GB Superior UHS-I microSDXC Memory Card from Silicon Power keeps up with the pace of your life, allowing you to capture Ultra HD 4K and Full HD video as well as raw and JPEG stills and bursts. Built with a storage capacity of up to 512GB, this card features a maximum read speed of 100 MB/s, a maximum write speed of 80 MB/s, and a thanks to its V30 / U3 rating, write speeds are guaranteed not to drop below 30 MB/s. If your device does not support V30 / U3, there is backward compatibility for Class 10 / U1 devices. Aside from support for UHS-I, V30, and U3, Silicon Power built this card with support for the Application Performance Class 2 (A2) spec, which includes optimizations to give Android users an improved mobile experience, delivering faster mobile app performance. The A2 spec allows the card to manage random read input-output access per second (IOPS) operations so it can quickly open apps and process accompanying tasks, such as audio, graphics, saved profiles, and in-app permissions. Designed and tested to withstand harsh environments, Silicon Power's 512GB Superior card is resistant against water, shock, and x-rays as well as temperature extremes of 32 to 158°F. Included is a dual slot USB-A 3.2 Gen 1 card reader, with one slot that supports SD/SDHC/SDXC and MMC cards and a second that supports microSD/SDHC/SDXC cards. Please note that both cards slots may not be used simultaneously. 512GB Superior microSDXC Memory Card Meets the UHS-I/U3 and the Video Speed Class 30 (V30) standards for 4K Ultra HD video recording Specifically designed for the high-speed capture of high-quality images and extended lengths of Full HD and 4K Ultra HD video with high-speed continuous shooting Meets the A2 standard for app performance, delivering minimum random reads of 4000 IOPS and random writes of 2000 IOPS as well as sustained sequential speeds of at least 30 MB/s Read speeds of up to 100 MB/s and write speeds of up to 80 MB/s respectively Speed may vary due to host and device configuration Up to 512GB storage capacity so you can get more out of your mobile devices Fit for apps, photos, videos, music, and games to meet all the needs of digital life on your smartphone, tablet, digital camera, video recorder, and more Waterproof, dustproof, temperature-proof, and X-ray-proof for use in extreme environments Equipped with an automatic error correction code (ECC) function Memory Card Reader: Combo card reader supports the most commonly used memory card formats with dual SD/MMC and microSD card slots SD/MMC Slot: SD, SDXC, SDHC, MMC microSD Slot: microSD, microSDXC, microSDHC Supports the usage of only one card slot at a time USB-A 3.2 Gen 1 interface provides up to 5 Gb/s of bandwidth for quick data transfers between the card reader and peripherals, which is up to 10 times faster than USB 2.0 Backwards-compatible with USB 2.0 (up to 480 Mb/s of bandwidth), which is convenient for systems with limited USB 3.2 ports Seamlessly works across major operating systems, including Windows, macOS, Linux, and Chrome OS Supports SD/microSD cards up to 2TB in capacity Supports Secure Digital v3.01 UHS-I DDR-200 speed mode True Plug-and-Play technology: no software or driver installation needed Powered directly from the USB port: no external power source required Compact size is portable-friendly for convenient access to card data almost anywhere Built-in LED indicator provides data transfer activity status
