Kaun sa SD Card Hai Best ?

Agar aap Mobile ka use sirf media file store karne ke liye karte hai to aap class 4 ka SD Card use kar sakte hai.

Agar aap phone se Full HD recording karna chahte hai to hamari recommendation anusar aap minimum class 6 ya usake upar ke class wala  koi bhi microSD card use kar sakte hai. Kyuki Full HD recording karte time data transfer rate high hota hai. Jiske liye high data transfer wale SD Card ki jarurat hoti hai.Yadi Aap low speed wala SD Card use karene to video sahi se nahi record ho payegi aur jab aap video dekhenge tab wah fas fas ke chalegi.

Aajkal phone me installed application ko SD Card me Move karne ka feature hota hai jiske liye aapko class 10 wala SD Card use karna hoga. Yadi aap class ka SD Card use karenge to kai application properly work nahi karenge ya slow speed se chalenge.

Agar Mobile aur Digital camera ke SDcard me 2K ya 4K Video recording karna hai to UHC class 1 wala SD Card bahot jaruri hai, kyu ki isake bina aap SD Card me 4k video recording nahi kar payenge.recordinDigital camera ke SDcard me 2K ya 4K Video recording karna hai to UHC class 3 wala card bahot jaruri hai, kyu ki isake bina aap sdcard me 4k video recording nahi kar payenge.
