Kingston Technology SDXC I memory card in its packaging. Here are the key specifications and details visible on the packaging and the card itself: Key Specifications * Capacity: \mathbf{128GB} * Brand: Kingston Technology * Card Type: SDXC I (Secure Digital eXtended Capacity, indicating a capacity of >32\text{GB} and using the UHS-I bus interface) * Speed Class: \mathbf{CLASS\ 10} (This is the traditional speed class, meaning a minimum sustained write speed of 10\text{MB}/\text{s}.) * UHS Speed Class: U1 (Indicated by the '1' inside the 'U' symbol next to \text{SDXC I}, meaning a minimum sustained write speed of 10\text{MB}/\text{s}.) * Application Performance Class: It does not explicitly show the A1 or A2 application performance class rating. * Stated Read Speed: \mathbf{90\text{MB}/\text{s}} * Stated Write Speed: \mathbf{45\text{MB}/\text{s}} * Intended Use: HD VIDEO (Indicates it's suitable for High Definition video recording.) Technical Details Explained * SDXC I: SDXC (Secure Digital eXtended Capacity) is the format used for capacities greater than 32\text{GB} up to 2\text{TB}. The 'I' indicates it uses the Ultra High Speed-I (UHS-I) bus interface, which supports theoretical speeds up to 104\text{MB}/\text{s}. * Class 10 / U1: Both ratings guarantee a minimum sustained write speed of 10\text{MB}/\text{s}. This is the speed required for recording 1080\text{p} Full HD video. * 90\text{MB}/\text{s} Read / 45\text{MB}/\text{s} Write: These are the card's maximum stated speeds under optimal conditions, specifically leveraging the UHS-I bus interface. The write speed is significantly higher than the guaranteed minimum of 10\text{MB}/\text{s}, making it a good choice for continuous shooting or higher-bitrate video. This type of card is commonly used in digital cameras, camcorders, tablets, and other devices that require high-speed, high-capacity storage.
