Konke okudingeka ukwazi mayelana namakhadi wememori ye-SDXC
Imemori khadi entsha ivele endaweni: SDXC. Lezi zimemori ze-flash zingasetshenziswa kwinani elikhulayo lamakhamera edijithali namakhamera wedijithali. Nakhu okudingeka ukwazi ngakho.
SDXC vs. SDHC vs. Ikhadi le-SD
Amakhadi we-SDXC ayinhloko yekhwalithi ephezulu yekhadi le-SDHC (okuyinto leyo inguhlobo oluphakeme lomthamo wekhadi le-SD langempela). Amakhadi we-SDXC aqala ngamakhono ka-64GB futhi angakhula abe namandla amakhulu okufinyelela kwe-2TB. Ngokuphambene, amakhadi we-SDHC angagcina kuphela ku-32GB yedatha futhi ikhadi le-SD elihloniphekile lingakwazi ukusingatha ku-2GB kuphela. Ukuze ufunde kabanzi mayelana namakhadi we-SDHC, chofoza lapha.
Kubanikazi be- camcorder , amakhadi we-SDXC anikezela isithembiso sokugcina amahora amaningi okucaciswa kwemifanekiso yevidiyo kunalokho ongakugcina ekhadini le-SDHC, ngakho-ke kunenzuzo ecacile.
Isivinini sekhadi le-SDXC
Ngaphezu kokunikeza amakhono aphezulu, amakhadi we-SDXC nawo afaneleka ngesivinini sokudlulisa idatha ngokushesha, enejubane elikhulu lama-300MB. Ngokuphambene, amakhadi we-SDHC angafinyelela ku-10MBps. Ukusiza ukuthi uthole isivinini esifanele, amakhadi we-SD / SDHC / SDXC ahlehlisiwe abe amakilasi amane: Amakilasi amabili, i-Class 4, i-Class 6 kanye ne-Class 10. Amakhadi e-Class 2 ahlinzeka ngesilinganiso esincane esilinganiselwe sedatha yama-megabytes amabili ngomzuzwana (MBps) , I-Class 4 ye-4MBps ne-Class 6 ye-6MBps ne-Class 10 ye-10MBps. Kuye ngokuthi iyiphi umkhiqizi othengisa ikhadi, isigaba sejubane sizovezwa ngokucacile noma singcwatshwe kuma-specs. Kungakhathaliseki ukuthi yikuphi, kufanele ubheke iso.
Kumakhamera wezincazelo ezijwayelekile, ikhadi le-SD / SDHC elinesivinini se-Class 2 yilokho okudingayo. Kuyashesha ngokwanele ukuphatha ividiyo ecacile yezinga eliphakeme levidiyo ongayibhala. Ukuze uthole amakhamera wezincazelo eziphakeme, amakhadi anesilinganiso se-Class 4 noma 6 esheshayo asheshayo ukubhekana namanani okudlulisa idatha ngisho nama-camcorders aphezulu kakhulu ekupheleni. Ngenkathi ungase ulingeke ukutshala ikhadi le-Class 10, uzokhokha ukusebenza okudingayo ku-camcorder yedijithali.
Ezimweni eziningi, amakhadi we-SDXC azonikezwa ngesivinini esheshayo kunokuba udinga ikhamera yedijithali. Lezi zivinini ezisheshayo ezinikezwa amakhadi we-SDXC ziyasiza kumakhamera edijithali - kubenza bakwazi ukuba nezinqubo eziphuthumayo ze-ultra-fast - kodwa akudingekile kumakhamera edijithali.
Izindleko zekhadi le-SDXC
Amakhadi we-SDXC aqala ukuhlunga emakethe ngasekupheleni kuka-2010 nasekuqaleni kuka-2011. Njenganoma yikuphi ukufometha kwenkumbulo entsha enikeza amakhono aphezulu kanye nesivinini esheshayo, kuzokubiza ngaphezu kwamandla amancane, amakhadi we-SDHC ahamba kancane. Kodwa-ke, njengoba abenzi bememori khadi ye-flash abanikeza amakhadi we-SDXC, izindleko kufanele zilahleke kakhulu kuneminyaka emibili elandelayo.
Ukuhambisana kwekhadi le-SDXC
Omunye umbuzo oseduze nanoma yiliphi uhlobo lwekhadi elisha kungakhathaliseki ukuthi lizosebenza kumadivayisi amadala, noma ngabe amadivaysi amasha azokwamukela amafomethi ekhadi asebekhulile afana ne-SDHC ne-SD. Ukuze uphendule umbuzo wokuqala, ikhadi le-SDXC lingasebenza kudivayisi endala engayisekeli ngokuqondile, kodwa ngeke ujabulele amandla amakhulu noma ngesivinini esisheshayo. Ama-cameras amaningi namakhamera azisa ngo-2011 ukwesekwa kwe-SDXC. Ukusekelwa kunomkhawulo kumakhamera kanye namakhamera asethwe ngo-2010. Uma ikhamera ithatha ikhadi le-SDXC lizosebenza njalo namakhadi we-SDHC ne-SD.
Ingabe Udinga Ikhadi le-SDXC?
Uma sikhuluma ngokuqinile nge-camcorder yedijithali, impendulo ayikho, hhayi okwamanje. Izinzuzo zamakhono zingakujabulela ngokuthenga amakhadi amaningi e-SDHC futhi njengoba kushiwo ngenhla, ukuthuthukiswa kwejubane akufanelekile. Kodwa-ke, uma unayo ikhamera ye-digital ephezulu, isivinini sithola isivinini se-SDXC sinokubukeka.
