Muaj tseeb koj tau pom ntau lub cim xeeb sib txawv thiab xav paub: lawv txhua tus sib txawv li cas? Ntau tus yam ntxwv thiab qhov chaw tsim khoom ntawm lub tshuab saib tsam yog cov ntaub ntawv tseem ceeb ntawm kev tsav ntawm hom no. Hauv tsab xov xwm no, lawv cov cuab yeej xws li chav kawm nrawm yuav raug txiav txim siab txhua yam. Cia peb pib!

Chav kawm cim xeeb daim npav ceev
Ib chav kawm yog qhov ntsuas uas qhia txog kev nrawm ntawm cov ntaub ntawv sib txauv ntawm daim npav cim xeeb thiab cov cuab yeej hauv nruab nrog. Qhov siab ceev ntawm tus tsav, cov duab ceev thiab cov ntaub ntawv yees duab yuav tau kaw rau ntawm nws, thiab tseem yuav muaj tsawg dua tus brake thaum lawv qhib thiab ua si. Txij li niaj hnub no muaj ntau txog li 3 chav kawm, txhua tus ntawm kuj yuav muaj qhov sib txawv, SD Card Koom Haum (txij li SDA) cov koom haum thoob ntiaj teb tau thov kos cim qee cov yam ntxwv ntawm SD cim xeeb daim npav ncaj qha rau lawv rooj plaub. Cov chav kawm tau muab lub npe SD Speed Class thiab tam sim no suav nrog: SD Chav, UHS thiab Chav Kawm Video.
Ua tsaug rau qhov kev txiav txim siab no, txhua tus neeg uas xav yuav ib qho kev tsav tsheb me me tuaj yeem tsuas yog saib nws lub ntim hauv khw thiab tau txais cov ntaub ntawv hais txog tus ceev nws txoj haujlwm. Tab sis koj yuav tsum tau saib tas li, vim tias qee cov tuam ntxhab tsis zoo, thaum kos npav, yuav muaj nyob rau hauv lub siab ceev ntawm kev nyeem ntawv los ntawm lub cuab yeej, ntau dua li sau ntawv rau nws, uas cuam tshuam qhov kev txiav txim siab ntawm SDA thiab ua tsis raug. Ua ntej yuav khoom, saib cov ntawv sim hauv Is Taws Nem lossis tshawb xyuas lub tsav ncaj qha hauv khw, nug tus muag khoom-tus kws pab tswv yim txog qhov no. Siv cov software tshwj xeeb, koj tuaj yeem tshawb xyuas daim yuaj yuav khoom hauv koj lub computer.

Sau Cov Chav Kawm Ceev
SD Chav Kawm, CCS, zoo li Video Hoob - cov qauv rau sau cia rau daim npav cim xeeb. Tus naj npawb uas qhia nyob ib sab ntawm cov ntawv luv yog tus nqi ntawm qhov tsawg kawg uas ua tau nrawm ntawm kev sau cov ntaub ntawv mus rau lub cuab yeej hauv qhov kev ntsuas tsis zoo. Qhov ntsuas no yog ntsuas hauv MB / s. Cov neeg nyiam tshaj plaws yog SD Class tus qauv thiab nws cov kev hloov pauv, muaj qhov cuam tshuam ntawm 2 txog 16 (2, 4, 6, 10, 16). Ntawm cov khoom siv, nws tau teev raws li tsab ntawv ntawm Latin cov tsiaj ntawv "C", sab hauv uas yog tus lej. Tus nqi no yuav qhia tau nrawm ntawm cov ntaubntawv povthawj siv.
Yog li, yog tias koj muaj tus lej 10 ntawm daim npav hauv tsab ntawv "C", tom qab ntawd qhov nrawm yuav tsum yog tsawg kawg 10 MB / s. Cov kauj ruam tom ntej hauv kev txhim kho ntawm cov teev cia cov qauv nrawm yog UHS. Ntawm cov npav nco nws yog qhia ua tsab ntawv "U", muaj cov lej lej Roman I lossis III lossis lawv cov Arabic. Tsuas yog tam sim no, tsis zoo li SD Class, tus naj npawb hauv cov cim yuav tsum tau khoo 10 - yog li koj paub cov cwj pwm tsim nyog.
Hauv xyoo 2016, SDA qhia cov kev xav tau sai tshaj plaws rau hnub tim - V Chav. Nws tau nrawm ntawm 6 txog 90 MB / s, nyob ntawm tus fiab. Daim npav uas txhawb nqa cov qauv no yog cim nrog tus tsiaj ntawv "V", tom qab nrog tus lej. Peb khoo tus nqi no los ntawm 10 thiab voila - tam sim no peb paub qhov tsawg kawg sau nrawm rau cov tsav no.
Tseem Ceeb: Ib daim npav nco tau tuaj yeem txhawb ntau, txog txhua 3, tus qauv nrawm, tab sis tsis yog txhua lub cuab yeej muaj peev xwm ua haujlwm nrog cov qauv sai dua li SD Class.
Cov Chav Kawm SD (C)
Cov chav kawm SD nce hauv kev ua lej xam, cov kauj ruam uas yog 2. Qhov no yog qhov nws zoo rau hauv daim npav cev.
- SD chav 2 muab kev nrawm ntawm tsawg kawg 2 MB / s thiab yog tsim rau cov ntaubntawv povthawj siv video nrog kev daws teeb meem ntawm 720 los ntawm 576 pixels. Daim vis dis aus no hu ua SD (cov qauv txhais, tsis yog yuav tsis pub leej twg paub nrog Secure Digital - qhov no yog lub npe ntawm daim npav nco daim ntawv nws tus kheej) thiab tau siv los ua qauv hauv TV.
- SD Chav Kawm 4 thiab 6 muab lub peev xwm los sau tsawg kawg 4 thiab 6 MB / s, txhua ntu, uas yuav tso cai rau koj los daws teeb meem HD thiab FullHD zoo. Cov chav kawm no yog tsim rau koob yees duab ntawm ntu ntu, lub xov tooj smartphones, kev siv phom thiab lwm yam khoom siv.
Tag nrho cov chav kawm tom ntej, mus txog UHS V Chav Kawm, hais txog cov ntaub ntawv twg yuav muab rau hauv qab no, tso cai rau koj sau cov ntaub ntawv rau tus tsav nrawm dua thiab ua haujlwm tau zoo.
UHS (U)
UHS yog qhov luv ntawm cov lus Askiv "Ultra High Speed", uas tuaj yeem txhais ua Lavxias ua "Ultra High Speed". Txhawm rau kom paub cov txheej txheem ceev yam tsawg kawg ntawm kev sau cov ntaub ntawv rau kev tsav nrog cov chav kawm ceev no, koj yuav tsum nce cov naj npawb qhia hauv lawv rooj plaub los ntawm 10.
- UHS 1 tau tsim rau qhov kev ua haujlwm zoo tua ntawm FullHD video thiab kaw cov kwj deg ntawm lub sijhawm. Cov lus cog tseg ceev ntawm txuag cov ntaub ntawv rau daim npav yog tsawg kawg 10 MB / s.
- UHS 3 yog rau sau cov ntaub ntawv video 4K (UHD). Siv hauv SLR thiab cov tsis muaj tsom iav thaij rau tua cov yeeb yaj kiab hauv UltraHD thiab 2K.
Video Chav Kawm (V)
Nws tau sau ua V Class thiab SD Card Association tau tsim tawm los tsim daim npav ua haujlwm kom zoo rau kev sau cov duab peb-seem thiab cov ntaub ntawv nrog kev daws teeb meem ntawm 8K lossis ntau dua. Tus lej tom qab tsab ntawv "V" qhia txog tus lej MB / s. Qhov tsawg kawg nkaus ceev rau daim npav nrog chav kawm ceev no yog 6 MB / s, uas tau sib haum rau chav kawm V6, thiab chav kawm siab tshaj plaws tam sim yog V90 - 90 MB / s.
Xaus
Hauv tsab xov xwm no, 3 chav kawm ceev uas daim npav nco - SD Chav Kawm, UHS thiab Chav Kawm Video yuav muaj kev txiav txim siab. SD chav kawm yog tsim los siv dav hauv ntau cov khoom siv, thaum lwm chav kawm yog tsim los kom muaj qhov sib txawv ntawm cov haujlwm. UHS tso cai rau koj los teev cov yees duab zoo hauv FullHD mus rau 4K hom ntawv thiab cov kev tshaj tawm hauv lub sijhawm, ua nws tus qauv rau cov koob yees duab qis. Video Chav Kawm tau tsim nyob rau hauv thiaj li yuav txuag loj loj video ntaub ntawv nrog daws teeb meem ntawm 8K, raws li tau zoo li 360 ° video, uas tau txiav txim siab qhov dauv ntawm nws daim ntawv thov - cov kws tshaj lij thiab cov khoom siv yees duab kim.
