Buying Guide: What to Look for in an SD Card for Audio Recording
Write Speed and Speed Class
Audio recording, especially high-resolution multi-track or 4K video with audio, demands consistent write speeds. Look for cards rated V30 or U3, which guarantee a minimum write speed of 30 MB/s. This ensures no dropped frames or audio glitches. The Gigastone cards and the SIX M200 all meet this standard, with the SIX offering read speeds up to 190 MB/s for fast transfers.

Storage Capacity and Reliability
Capacity matters for long recording sessions. A 512GB card like the Gigastone can hold hundreds of hours of uncompressed audio, while 128GB options are great for daily use. Beyond size, reliability is key. All three cards come with warranties and data recovery support, giving you peace of mind.

Compatibility with Recording Devices
Not all SD cards work well with every recorder. Micro SD cards with adapters are versatile, but ensure your device supports UHS-I and the required speed class. The Gigastone cards are compatible with a wide range of cameras, drones, and smartphones, while the SIX M200 is optimized for action cameras and dash cams.
