TF Card Specification

compatibility

• High Speed TF cards follow standards published by the SD Association and are therefore compatible with a wide range of devices that support microSD cards. However, it should be noted that different devices have different support limits for the speed and capacity of TF cards. For example, some older devices may only support Class 10 cards and not the higher speed UHS-I or UHS-II cards.
• A1 and A2 Application performance: Some high-performance TF cards are labeled with A1 or A2 ratings to indicate that they provide better response and performance when running applications. This is especially important for applications such as smartphones.
• A1: Random read 1500 IOPS, random write 500 IOPS.
• A2: Random read 4000 IOPS, random write 2000 IOPS (A2 cards are suitable for demanding applications such as fast-loading applications or handling large files).
