Frequently Asked Questions
How much 4K video can 256GB store?
The actual recording time depends on video bitrate. At 100Mbps (typical for 4K60), 256GB stores approximately 5.5 hours of video. At 60Mbps (4K30), approximately 9.5 hours. At higher bitrates like 400Mbps (professional 4K), about 1.4 hours. The V30 rating ensures the card can sustain 30MB/s (240Mbps) write speed required for most 4K recording.
256GB provides 5-10 hours of 4K video depending on quality settings.
What does A2 rating mean?
A2 (Application Performance Class 2) rating guarantees minimum 4000 IOPS read and 2000 IOPS write performance for running apps directly from the microSD card. This is important for Android devices using Adoptable Storage or running apps from SD card. A2 cards provide significantly better app launch and execution performance compared to A1 or non-rated cards. For best app performance, choose A2 rated cards.
A2 rating ensures good performance for apps installed on microSD.
Is this card compatible with Nintendo Switch?
Yes, the FM256-V30 is fully compatible with Nintendo Switch and Switch Lite. The 256GB capacity can store approximately 30-60 games depending on size. The high read speed ensures fast game loading. The card meets Nintendo's performance requirements for game storage and downloads. For Switch OLED or original Switch, this card provides excellent expansion capacity.

Can I use this card for security cameras?
Yes, the FM256-V30 can be used in security cameras that support microSD storage. The high endurance of 256GB capacity provides days of continuous recording depending on resolution and quality settings. For 24/7 continuous recording, consider high-endurance cards specifically designed for surveillance use. For motion-activated recording, this card provides excellent capacity and reliability.
Suitable for security cameras, especially motion-activated recording.
What is the difference between U3 and V30 ratings?
U3 (UHS Speed Class 3) and V30 (Video Speed Class 30) both guarantee 30MB/s minimum sustained write speed. U3 is the older rating system, while V30 is newer and specifically designed for video recording. V30 testing is more stringent for sustained performance required by video cameras. For video recording, V30 is preferred, while U3 is sufficient for general use. This card carries both ratings for maximum compatibility.
Both U3 and V30 indicate 30MB/s write - V30 preferred for video.
