Gcina izithombe zakho namavidiyo agcinwe kulezi khadi ze-SD eziphezulu
Uma kuziwa ekutholeni ikhadi le-SD elifanele lekhamera yakho noma ikhamera yevidiyo noma ngisho nokugcina umculo wakho we-digital, kunezinkampani ezimbalwa kuphela ozidingayo ukuze uqaphele: umthamo nokubhala (ukudlulisa aka) ngesivinini.
Amandla ngokusobala kubaluleke kakhulu ukuthi zingaki izithombe noma ukusakazwa kwevidiyo ongakuthola ngempela ekhadini.
Kodwa futhi ufuna ukulalela isivinini sokubhala. Ijubane lokubhala elincane linganciphisa isikhathi sakho sokudutshulwa noma ngisho nenani lezithombe ongazithatha ngesikhathi esinikeziwe. Lokhu kungabonisa inkinga kuye ngokuthi uhlobo luni lwezithombe ozenzayo. Lapha, senze uhlu lwamakhadi we-SD asemqoka ngokusekelwe kohlobo nenhloso.
Funda lokhu uma udinga ukufometha ikhadi le-SD usebenzisa iWindows .
Uma ufuna okuthile ngama-specific beefier specs futhi uzimisele ukuchitha amanye amadola, kufanele uhlole iSanDisk Extreme PLUS 32GB microSDXC. Yenzelwe futhi ihlolwe ngezimo ezinzima, ngakho-ke ngabe udubula phezulu kwentaba noma phansi kwechibi, ungathembela kuma-specs ayo angenasiphelo, angenawo amanzi kanye namahhala. Ukwengeza, lifunde ngokusheshisa nokubhala; linikeza isivinini sokubhala esihlaba umxhwele esingaba ngu-90 MB / s futhi sifinyelele ngesivinini esingama-95 MB / s. Isikhundla se-Class 3 sisho ukuthi singakwazi ukurekhoda ukurekhoda kwevidiyo ye-4K Ultra HD kalula, futhi ifike nesipho sokulanda se-software ye-RescuePRO Deluxe yokutakula idatha, okukuvumela ukuba uphinde ulandele amafayela asuswe ngengozi. I-SanDisk Extreme PLUS itholakala ku-SDHC (16 GB) nase-SDXC (ama-32 GB no-64 GB) amafomethi.
Leli khadi le-SD eliphezulu le-plug-and-shoot liphelele kubathwebuli bezithombe kuwo wonke amazinga, isivinini sokulinganisa ngenani nokuxhaswa kwemibandela yesimiso esiqinile sememori yonke. Iqukethe ukuhambisana kweklasi le-UHS-1 / U3, okusho ukuthi ingakwazi ukuphatha izithombe namavidiyo angu-4k, kanye nawo wonke amanye amafomethi wefayela. Ishaya isivinini sokufunda sama-95Mb / s nokubhala isivinini se-90MB / s, ikuvumela ukudlulisa amafayela amakhulu ngesivinini esheshayo. Iphinde isekele imodi eqhumayo yokudubula okuqhubekayo, futhi iyamangalisa futhi ingabi namanzi okuyosinda ekuphumeni okukhulu.
Uma ubheka okuthize eshibhile futhi ungacabangi ukuhamba okubhaliwe okusheshayo (mhlawumbe awusona umdwebi wezithombe ezisheshayo), usuke uphephile ngokuphephile ngebhajethi ikhadi le-SD. I-SanDisk Ultra yilelo khadi. Itholakala ku-16, 32, 64, no-128 GB, futhi inikezela umbhalo obhaliwe ongaba ngu-10 MB ngesigamu, okusho ukuthi kungaba nzima ukuqhubeka nokudubula okufakwe kufomethi ye-RAW. Ukufunda / ukusheshisa okusheshayo kuyashesha kakhulu ku-80 MB / s. Lokhu kuyashesha kunokwedlule i-Ultra SD yaseSanDisk, eyanikeza ukuvinjelwa kokufunda okungama-40 MB / s. Noma ngabe yikuphi, lokhu kuyindlela eqinile yabathwebuli bezithombe ezingavamile abangalindele ukudubula amafomethi amafomethi angu-10 ububanzi okwesibili. Awuzinamanzi, awunakufudumala, awunamakhaza, ubufakazi be-X, i-magnetproof ne-shockproof, futhi unewaranti eneminyaka engu-10. Iningi labantu lizohamba lijabule.
Uma ufuna isamba, uzofuna ukuthola ibhalansi elungile lentengo nokusebenza. Leli khadi lememori le-Elite Series lishaya ibhalansi. Ifinyelela ekuhambeni kokufunda nokubhala kufika ku-85MB / s (8GB kuya ku-64GB) no-75MB / s (128GB) futhi inikeza isitoreji esivelele nokufinyelela kahle. Imininingwane yayo ye-UHS-1 ye-Class 10 yenza ukusheshisa okusheshayo kokudlulisa ifayela futhi kusekela ukuqoshwa kwevidiyo ephelele ye-HD. Uma ngabe uhlala uqinile, leli khadi le-SD lizofanelana nalo mthethosivivinywa: Awukwazi ukungena amanzi futhi awusabeka, ukuzivikela emshinini wemikhumbi ye-X-ray futhi angaphila amazinga okushisa angaphansi kuka -40 degrees Celsius futhi aphezulu ngo-85 degrees Celsius. Kuye ngezidingo zakho, ungathenga ku-128GB isikhala, futhi wonke amakhadi afika newaranti yokuphila.
Uchungechunge lwe-Evo oluvela ku-Samsung lunikeza inani elimangalisayo lentengo ngoba lilungiselele la makhadi e-SD ngamafayela amakhulu wevidiyo we-UHD kanti futhi futhi ukugcina intengo engama-64GB ngaphansi kwe-$ 20 - ayikho encane uma ubheka ukuthi leli khadi lisebenza kahle kangakanani. Lo mandla we-64GB unikeza ukuvinjelwa okufundwayo kufika ku-100 mb / s, ngokubhala ngokusheshisa kokubhala ku-60 mb / s. Lokho okusheshayo okubalulekile ukuze kuhambisane nokudluliswa kwevidiyo ye-3GB kungakapheli imizuzwana engu-38 (ngaphansi kwezimo ezithile). Ngokuqinisekile lokho kuyakhala kakhulu kusukela ezinsukwini zama-floppy disks. Umthamo ogcwele ungakwazi ukuhlala kumahora angu-8 namaminithi angu-30 evidiyo ephelele ye-HD, izithombe ezingu-14,000 noma izingoma ezingu-5 500.
Ikhadi lihlolwe ngamadivayisi amaningi ahlukahlukene kusuka kumathebulethi kuya kumakhamera kuya kumafoni nokunye, futhi angakwazi ukufaka amavidiyo angu-4K, futhi. Ukuvikeleka kwamaphuzu amane e-Samsung okusho amahora angu-72 emanzini olwandle, amazinga okushisa okwedlulele, imishini ye-X-ray yasesikhumulweni sezindiza, kanye nezinsimu zamagnetic ezilingana nomshini we-MRI, ngakho-ke ikhadi lizohamba ngokuyinhloko lapho ufuna khona ngaphandle kokukhishwa. Inikeza ibanga lesi-3 kanye nokuhlukaniswa kweklasi 10, okusho ukuthi cishe njengenqubo njengoba ithola, futhi ifika ne-adapter yekhadi le-SD eligcwele.
Manje singena endaweni yesikhundla esiphakeme, amakhadi we-SD aphezulu aphezulu abathwebuli bezithombe abathintekayo, abaphezulu bezithombe nabakhiqizi bevidiyo. Ngenkathi i-pricey encane, amakhadi we-Lexar Professional 2000x SDHC ne-SDXC atholakala ku-32, 64 no-128 GB. Kungani ungayisebenzisa kakhulu ngalekhadi le-SD? Ngoba uthola mhlawumbe ikhadi le-SD elingcono kakhulu emakethe, futhi mhlawumbe ngoba ungumthwebuli wezithombe ongeyena ongasondeli. Ifomethi ngayinye inikeza isivinini esimangalisayo sokufunda / ukudlulisa kufika ku-300MB / s. Bhala ukuvinjelwa kuhle kakhulu okuqinisekisiwe ukuthi kuhamba kancane kunalokho, kodwa kuye ngokuthi izimo zakho, zingakwazi ukufinyelela kufinyelele ku-275 MB / s. Kungakhathaliseki ukuthi, i-Lexar Professional ingasingatha ividiyo engu-1080p (i-HD Full), i-3D, ne-4K, noma ngabe uyadutshulwa kusuka kukhamera ye-DSLR, ikhamera yevidiyo ye-HD noma ikhamera ye-3D. Le nto isetshenziselwa ukusingatha izimo ezihlukahlukene futhi ifakwe ukwenza kanjalo ngejubane elingakaze livele.
Ikhadi le-SD le-Lexar Pro 256GB 10 le-SD yenza ncamashi yonke into ongayethemba ukuthi kufanele yenze - idlulisela idatha ngesivinini esiphezulu futhi ithatha ithoni yayo. Ikhadi isebenzisa ubuchwepheshe be-UHS-I ngokudluliselwa okusheshayo iwashi ngesivinini se-95 MB / s kumazinga afundwayo nokubhala okungama-45 mb / s ngokubhala. Kodwa yini ongayifunda nokubhala ngalezo zivinini? Leli khadi le-SD elihle lihlelelwe ikhwalithi ephakeme, izithombe eziluhlaza, kanye nemifanekiso egcwele yevidiyo esuka ku-1080p yonke indlela eya ku-4K, futhi isekela amafayela amakhulu we-3D amakhulu. Njengoba kunjalo, kuzosebenza ukufometha nge-DSLR yakho, ikhamera noma ikhamera ye-3D.
Amakhadi ahlolwe ngokuqinile emalabhu we-Lexar's Quality ukuqinisekisa ukuthi azosebenza ngokungaphazanyiswa njengoba adlulisiwe. Kodwa uma ngenxa yezizathu ezithile, ihluleka futhi ulahlekelwa amanye amafayela, i-Lexar ifake ilayisensi yokuphila yesofthiwe yabo yokubuyisela izithombe ezokwenza konke okusemandleni ukubuyisela amafayela alahlekile ngenxa yediski ekhohlakeleyo.
Isinyathelo esiphansi kokubili kwe-Toshiba Exceria Pro ne-Lexar Professional, i-Transcend Class 10 line ye-SDHC namakhadi we-SDXC anikeza ama-specs aphezulu aphethwe ngamaphuzu aphansi amanani. I-GB GB 32 ye-32 ingatholakala ngaphansi kwama-$ 50, kuyilapho i-64 GB SDXC ibiza cishe u-$ 70. Bobabili banikeza ukuvinjelwa kokufunda nokubhala kuka-285 MB / s kanye no-180 MB / s, ngokulandelana, futhi kokubili kufaka ubuchwepheshe be-ECC eyakhelwe ngaphakathi esiza ukuthola nokulungisa ukubhala nokudlulisa amaphutha. Abanikazi banikezwa ngokukhululeka kwamafayela we-RecoveRx software yokutakula idatha. Lokhu kuyindlela enhle yabadwebi bezithombe nabakhiqizi bevidiyo abakhetha ukudubula ku-RAW noma ama-video aphezulu we-4K aphezulu-noma yini engase idale ukuhamba okukhulu kwedatha. Ngenkathi isesezingeni elincane, amakhadi we-Transcend SD angase abe yindlela engabizi kakhulu kunomzila we-Toshiba's Exceria Pro.
