memory card ki speed 

memory card ki speed ek aham feature hai. ise is baat se naapa jaata hai ki memory card mein kitani speed se ek photo jaisee digital janakaari saheji ja sakati hai ya nicali ja sakati hai. kai baar aapane dekha hoga ki camara, kishi photo ko sahejate huye kuchh zyaada he samay le leta hai, busy ka sanket deta rahata hai ya kisi video ko dekhate hue baar-baar rukaavat aati hai. 

darasal, memory card vaala har divaes ek khaas speed vaale card ke liye bana hota hai.

us se kam speed vaala memory card laga ho to vah apekshit parinaam nahin de paega.

hum mein se zyadatar log is par koi khaas dhyaan nahin dete. aksar log jo divaes 16gb tak ki memory card ke liye bana hai, us mein 8gb/16gb ka card dalava lete hain, lekin card ki speed par dhyaan nahin dete. 

  to agali baar agar aapako lage ki aapaka camara photo lene ke baad use store karane mein jyaada samay le raha hai ya kam kordar kishi video ko lete samay theek se kaam nahin kar raha hai, to behatar hoga ki pahale yah dekh len ki memory card ki speed, divais ke hisaab se theek hai ya nahin.

memari card mein class 2 sabase dhimi aur class 10 sabase tez speed hoti hai.

Ab agar aapake camare ki kshamata class 4 vaale memory card ki hai to class 4 memory card ka istemaal karana hi samajhadari hai. 

isase jyaada speed vaale card ka istemaal koi maayane nahin rakhata, kyonki camara jyaada speed vaale card ki kshamata ka sdupyog kar hi nahin paega. 

dhyaan dene ki baat yah hai ki ek hi storej capacity (jaise 16gb) vaale card ki speed jitni badhati jaegi, usaki kimat bhi utani hi badhati jaegee.

kaise jaanen card ki speed

ho sakata hai ki card par mb/second mein speed likhee ho. agar aisa nahin hai, to aap card ki gati ki pahachaan card par bane chihnon se kar sakate hain.
