I-Compact Flash vs SD memory card yekhamera yakho

ngo kim Kubuyekezwe: June 26, 2022

Iningi lesithombe nevidiyo Amakhamera sebenzisa imemori khadi. CF noma Compact Flash cards zithandwa ochwepheshe, kodwa SD noma Amakhadi e-Secure Digital akhule ekudumeni eminyakeni yamuva nje.

Nakuba kungeke kube into ehamba phambili yokuqala lapho ukhetha ikhamera entsha, kuyasiza ukwazi okuhle nokubi kwesistimu ngayinye kangcono kancane.

I-Compact Flash (CF) Imininingwane

Le sistimu yake yaba indinganiso yamakhamera e-DSLR aphezulu. Isivinini sokufunda nokubhala sasishesha, futhi umklamo uzizwa uqinile futhi uqinile.

Amanye amakhadi nawo amelana kakhulu namazinga okushisa aphezulu, okungaba yisixazululo ezimeni zomsebenzi. Namuhla, intuthuko isicishe yama, futhi amakhadi e-XQD angabalandeli bohlelo lwe-CF.

Yini esekhadini?

1. Lapha ungabona ukuthi ikhadi linomthamo ongakanani, liyahluka phakathi kuka-2GB no-512GB. Ngevidiyo ye-4K, igcwala ngokushesha, ngakho-ke thatha umthamo owenele, ikakhulukazi ngokurekhodwa okude.
2. Lesi isivinini sokufunda esiphezulu. Empeleni, lezi zivinini azifinyelelwa kalula futhi isivinini asishintshi.
3. Isilinganiso se-UDMA sibonisa ukucaciswa kokuphuma kwekhadi, kusuka ku-16.7 MB/s ku-UDMA 1 kuya ku-167 MB/s ku-UDMA 7.
4. Lesi isivinini esincane sokubhala sekhadi, esibaluleke kakhulu kubathwebuli bevidiyo abadinga isivinini esiqinisekisiwe esingaguquki.

Vikela Imininingwane Yedijithali (SD).

Amakhadi e-SD aduma ngokushesha kangangokuthi ngokuhamba kwesikhathi adlula i-CF kukho kokubili umthamo wesitoreji nesivinini.

Amakhadi e-SD ajwayelekile anqunyelwe uhlelo lwe-FAT16, i-SDHC elandelayo isebenza ne-FAT32 ekuvumela ukuthi urekhode amafayela amakhulu, futhi i-SDXC inohlelo lwe-exFAT.

I-SDHC ikhuphukela ku-32GB futhi i-SDXC ikhuphukela ku-2TB womthamo.

Ngo-312MB/s, izicaciso zesivinini zamakhadi e-UHS-II cishe zishesha ngokuphindwe kabili kunalezo zamakhadi e-CF. Amakhadi e-MicroSD ayatholakala futhi ezinhlobonhlobo ezintathu ezingenhla futhi angasebenza ne-adaptha.

Uhlelo “lubuyela emuva luhambisana”, i-SD ingafundwa ngomfundi we-SDXC, ayisebenzi ngenye indlela.

Yini esekhadini?

1. Lona umthamo wokugcina ikhadi, ukusuka ku-2GB wekhadi le-SD ukuya ku-2TB wekhadi le-SDXC.
2. Isivinini sokufunda esiphezulu ongeke usithole uma uke wasizuza ngokwenza.
3. Uhlobo lwekhadi, khumbula ukuthi amasistimu “ayahambisana emuva” kuphela, ikhadi le-SDXC alikwazi ukufundwa kudivayisi ye-SD evamile.
4. Lesi isivinini esincane sokubhala sekhadi, esibaluleke kakhulu kubathwebuli bevidiyo abadinga isivinini esiqinisekisiwe esingaguquki. Ikilasi lesi-3 le-UHS alehli ngaphansi kuka-30 MB/s, ikilasi loku-1 alihambi ngaphansi kuka-10 MB/s.
5. Inani le-UHS libonisa isivinini sokufunda esiphezulu. Amakhadi angenayo i-UHS akhuphukela ku-25 MB/s, i-UHS-1 ikhuphukela ku-104 MB/s futhi i-UHS-2 inomkhawulo ongu-312 MB/s. Sicela uqaphele ukuthi isifundi sekhadi kufanele futhi sisekele leli nani.
6. Lona umanduleli we-UHS kodwa abakhiqizi abaningi bamakhamera basasebenzisa lesi sihloko. Ikilasi le-10 liwumkhawulo ngo-10 MB/s futhi isigaba 4 siqinisekisa u-4 MB/s.

Amakhadi e-SD anenzuzo eyodwa encane kodwa ewusizo ngenxa yeswishi encane yokuvikela ikhadi ekusulweni. Noma yiluphi uhlobo lwekhadi olisebenzisayo, awusoze wabanela!

Sawubona, nginguKim, umama kanye nomshisekeli we-stop-motion onesizinda ekudalweni kwemidiya nokuthuthukiswa kwewebhu. Nginothando olukhulu lokudweba nokugqwayiza, futhi manje sengingena ngekhanda emhlabeni onyakazayo. Ngebhulogi yami, ngabelana ngezifundo zami nani bafana.
