Capacity Guide

Due to the industry-standard difference in how manufacturers and operating systems calculate storage, formatted capacity will appear slightly lower than labelled:

• 32GB ≈ 28–30 GB usable
• 64GB ≈ 56–60 GB usable
• 128GB ≈ 112–120 GB usable
• 256GB ≈ 225–240 GB usable

This is a standard calculation difference between the manufacturer (1GB = 1 billion bytes) and your PC/OS (1GB = 1,073,741,824 bytes). It is not a defect.

Frequently Asked Questions

Q: Is this a genuine SanDisk Extreme SD card or a third-party compatible card?

A: This is a 100% original, authentic SanDisk Extreme SD card supplied in official retail packaging. Every unit sold is a genuine SanDisk product in full compliance with the official SanDisk product line.

Q: Which cameras and devices are compatible with the SanDisk Extreme SD card?

A: The SanDisk Extreme SD card is compatible with any device that accepts a standard SD/SDHC/SDXC card, including DSLR and SLR cameras, mirrorless cameras, action cameras, drones (UAVs), dashcams, notebooks, and other digital devices that support UHS-I.

Q: What does V30 / U3 / C10 mean, and why does it matter for 4K video?

A: V30 means a guaranteed minimum sustained write speed of 30MB/s; U3 and Class 10 confirm the same minimum threshold under the UHS and SD speed class standards. Together, these ratings ensure the card can handle the continuous high data rates required for 4K UHD video recording without dropped frames or buffering.

Q: Why does the usable storage appear less than the labelled capacity?

A: Manufacturers define 1GB as 1 billion bytes, while computers and operating systems calculate 1GB as 1,073,741,824 bytes. This difference — not a fault with the card — means formatted capacity appears slightly smaller than the labelled size on every flash storage product industry-wide.
