Specifications

About Displayed Capacity

Flash memory manufacturers calculate capacity using a decimal system (1 GB = 1,000,000,000 bytes), while operating systems use binary (1 GB = 1,073,741,824 bytes). As a result, the usable capacity shown on your device may appear slightly lower than the labeled size. This is standard across all flash storage products and is not a defect.

• 32GB ≈ 28–29 GB (usable)
• 64GB ≈ 58–59 GB (usable)
• 128GB ≈ 95–119 GB (usable)

⚠️ Important: Check Device Compatibility Before Purchasing

Before buying, please confirm your device supports the capacity you intend to purchase. Inserting a card that exceeds your device's maximum supported capacity may prevent the card from functioning — this is a device limitation, not a product defect.

Note: High-speed read/write performance is best measured using a USB 3.0 or higher card reader or interface.

Frequently Asked Questions

Q: Is this Micro SD card compatible with my Android smartphone?

A: Yes — the BESY Micro SD card is compatible with most Android smartphones, tablets, and other devices that accept a standard TF/Micro SD card slot. Just check your device's maximum supported card capacity before purchasing to ensure proper functionality.

Q: What video quality does the V30 rating support?

A: The V30 (Video Speed Class 30) rating guarantees a minimum sustained write speed of 30 MB/s, which is sufficient for recording smooth 4K Ultra HD video. Combined with the U3 and A2 ratings, this card handles high-bitrate video and rapid-fire photography with ease.

Q: What format should I use when setting up this card?

A: For 32GB cards, format using FAT32. For 64GB and 128GB cards, format using exFAT. Most devices will prompt you to format when inserting a new card. Always back up existing data before formatting.

Q: Why does my device show less storage than the labeled capacity?

A: This is a standard difference between how manufacturers and operating systems calculate storage size. Manufacturers use decimal math (1 GB = 1,000,000,000 bytes), while operating systems use binary math (1 GB = 1,073,741,824 bytes). The actual usable space is fully functional — the discrepancy is purely a display difference.
