TF Card Specification

Technical standards and classifications

• Ultra High Speed (UHS) : The high-speed TF card usually supports the UHS-I, UHS-II, or UHS-III standards. UHS-II and UHS-III offer higher read and write speeds for devices that require higher data transfer rates.
• SDXC vs. SDHC vs. SDSC:
• SDHC (Secure Digital High Capacity) : The capacity ranges from 4GB to 32GB, suitable for common data storage requirements.
• Secure Digital eXtended Capacity (SDXC) : The capacity ranges from 32GB to 2TB. SDXC is suitable for devices that require large-capacity storage.
• SDSC (Secure Digital Standard Capacity) : The capacity is usually under 2GB, the early standard, and is now less used.

Application scenario

• High speed TF cards are widely used in devices that require fast data storage and reading. For example:
• Hd video recording: The high-speed card supports video recording in 4K or even 8K resolution.
• Continuous shooting: In high-speed continuous shooting digital cameras, the writing speed of the card directly affects the effect of the shooting.
• Game and application storage: For portable game consoles or smartphones that require large capacity and fast access, fast TF cards can improve game loading speed and system response speed.
