Frequently Asked Questions
Quick answers to common questions about micro sd card
Q1What is the difference between SDHC and SDXC?+

Q3Is a higher read/write speed always better?+
Yes, higher read/write speeds generally improve performance, especially for tasks like transferring large files and recording high-resolution video. However, your device must also support these speeds to take full advantage of them.

Q5How do I choose the right capacity microSD card?+
Consider your storage needs based on the types of files you'll be storing (photos, videos, apps) and the resolution of your media. It's always better to overestimate your needs to avoid running out of space.
