I-Compact Flash vs imemori khadi ye-SD yekhamera yakho

ngo kim Ukuhlaziywa: Juni 26, 2022

Uninzi lweefoto kunye nevidiyo Iikhamera sebenzisa iimemori khadi. CF okanye Compact Flash cards zithandwa ziingcali, kodwa SD okanye Secure Digital amakhadi akhule ekuthandeni kwiminyaka yakutshanje.

Nangona kungayi kuba yeyona nto iphambili xa ukhetha ikhamera entsha, kuyanceda ukwazi okuhle kunye nokubi kwenkqubo nganye ngcono kancinci.

IiNkcazelo ze-Flash Flash Compact

Le nkqubo yayikhe yaba ngumgangatho weekhamera ze-DSLR eziphezulu. Isantya sokufunda nokubhala sasikhawuleza, kwaye uyilo luziva lomelele kwaye lomelele.

Amanye amakhadi nawo axhathisa ngakumbi kumaqondo obushushu aphezulu, anokuba sisisombululo kwiimeko zobungcali. Kule mihla, uphuhliso luphantse lwayeka, kwaye amakhadi e-XQD angabalandeli benkqubo yeCF.

Yintoni ekwikhadi?

1. Apha unokubona ukuba lingakanani umthamo wekhadi, liyohluka phakathi kwe-2GB kunye ne-512GB. Ngevidiyo ye-4K, igcwalisa ngokukhawuleza, ngoko ke thatha ngaphezu komthamo owaneleyo, ngakumbi ngokurekhoda okude.
2. Esi sesona santya siphezulu sokufunda. Ngokwesiqhelo, ezi zantya azifikelelwanga kwaye isantya asitshintshi.
3. Ukulinganiswa kwe-UDMA kubonisa iinkcukacha ze-throughput yekhadi, ukusuka kwi-16.7 MB / s ye-UDMA 1 ukuya kwi-167 MB / s ye-UDMA 7.
4. Le yeyona santya sisezantsi sokubhala ikhadi, elibaluleke kakhulu kubadlali bevidiyo abafuna isantya esiqinisekisiweyo esithe rhoqo.

Ukhuseleko lweDijithali (SD) Iinkcukacha

Amakhadi e-SD athandwa ngokukhawuleza kangangokuba ekuhambeni kwexesha agqwesa iCF kuzo zombini amandla okugcina kunye nesantya.

Amakhadi e-SD asemgangathweni anqunyelwe yinkqubo ye-FAT16, i-SDHC elandelayo isebenza kunye ne-FAT32 evumela ukuba urekhode iifayile ezinkulu, kwaye i-SDXC inenkqubo ye-exFAT.

I-SDHC inyukela kwi-32GB kwaye i-SDXC ide inyuke iye kuthi ga kwi-2TB yomthamo.

Nge-312MB / s, iinkcukacha zesantya samakhadi e-UHS-II ziphantse ziphindwe kabini ngokukhawuleza kunamakhadi e-CF. Amakhadi eMicroSD ayafumaneka kwezi ntlobo zintathu zingasentla kwaye anokusebenza ngeadaptha.

Inkqubo “ibuyela ngasemva iyahambelana”, i-SD inokufundwa nomfundi weSDXC, ayisebenzi ngenye indlela.

Yintoni ekwikhadi?

1. Lo ngumthamo wokugcinwa kwekhadi, ukusuka kwi-2GB yekhadi le-SD ukuya kubuninzi be-2TB kwikhadi le-SDXC.
2. Esona santya siphezulu sokufunda ongafane usifezekise xa usenza.
3. Uhlobo lwekhadi, khumbula ukuba iinkqubo kuphela "zihambelana ngasemva", ikhadi le-SDXC alikwazi ukufundwa kwisixhobo esiqhelekileyo se-SD.
4. Le yeyona santya sisezantsi sokubhala ikhadi, elibaluleke kakhulu kubadlali bevidiyo abafuna isantya esiqinisekisiweyo esithe rhoqo. Iklasi ye-3 ye-UHS ayihambi ngaphantsi kwe-30 MB / s, iklasi 1 ayihambi ngaphantsi kwe-10 MB / s.
5. Ixabiso le-UHS libonisa esona santya siphezulu sokufunda. Amakhadi angenayo i-UHS aya kwi-25 MB / s, i-UHS-1 iya kwi-104 MB / s kwaye i-UHS-2 inobuninzi be-312 MB / s. Nceda uqaphele ukuba umfundi wekhadi kufuneka naye alixhase eli xabiso.
6. Lo ngumanduleli we-UHS kodwa uninzi lwabavelisi beekhamera basalusebenzisa olu bizo. Udidi lwe-10 luphezulu kunye ne-10 MB / s kunye neklasi yesi-4 iqinisekisa i-4 MB / s.

Amakhadi e-SD anenzuzo enye encinci kodwa eluncedo ngenxa yokutshintsha okuncinci ukukhusela ikhadi ekucimeni. Nokuba loluphi uhlobo lwekhadi olisebenzisayo, awunakuze ube nalo laneleyo!

Molo, ndinguKim, umama kunye nomthandi we-stop-motion onemvelaphi kwindalo yemidiya kunye nophuhliso lwewebhu. Ndinothando olukhulu lokuzoba kunye noopopayi, kwaye ngoku ndintywila kuqala kwihlabathi le-stop-motion. Ngebhlog yam, ndabelana nawe ngokufunda kwam.
