1What storage capacity should I choose for my phone or camera?
For smartphones, 64GB or 128GB is usually enough for photos and videos, while 256GB suits heavy users who store lots of 4K footage. Check your device's actual usage—most people rarely fill beyond 128GB unless they're filming constantly.
2What's the difference between V30 and V90 speed ratings?
V30 means minimum 30MB/s write speed (fine for 1080p video), while V90 guarantees 90MB/s (needed for 4K and 8K recording). Pick V30 for general use, but go V90 if you're filming in high bitrate formats or using action cameras.
3Does the brand of micro SD card really matter?
Reputable brands like SanDisk, Kingston, and Samsung have better reliability and warranty support, while unknown brands have higher failure rates. The small price difference isn't worth the risk of losing your photos or videos to a faulty card.
4What's UHS-II and do I need it?
UHS-II offers faster read/write speeds (up to 312MB/s) but only works if your device supports it—most phones don't. Check your device specs first; for standard phones and basic cameras, standard UHS-I cards work perfectly fine.
5How do I know if a micro SD card is fake?
Buy from authorized retailers rather than third-party sellers, and verify the card's serial number on the manufacturer's website if possible. Suspiciously cheap prices and poor packaging are red flags for counterfeit products.
