Esikhathini sedijithali, ukubaluleka kwezisombululo zesitoreji ezinokwethenjelwa nezinwetshiwe akukwazi ukweqiwa. Ikhadi le-SDXC, elimele I-Secure Digital Extended Capacity, liwumthombo wamandla endaweni yamamemori khadi, anikeza umthamo omkhulu wokulondoloza kanye nesivinini. Lo mhlahlandlela uzohlola ubunkimbinkimbi bamakhadi e-SDXC, ukusebenza kwawo, izinzuzo, kanye nezeluleko ezisebenzayo mayelana nokukhetha nokusetshenziswa.
Okuqukethwe:
1. Liyini ikhadi le-SDXC?
2. Lisebenza kanjani ikhadi le-SDXC?
3. Izinzuzo kanye nezithiyo zekhadi le-SDXC

Liyini ikhadi le-SDXC?
Amakhadi e-SDXC, inguquko elandelayo emugqeni wokugcina we-Secure Digital (SD), aklanyelwe ukuhlangabezana nesidingo esandayo somthamo ophezulu, izinketho zokugcina ezinesivinini esikhulu. Ngokungafani nabanduleli bawo, amakhadi e-SDHC (High Capacity), aphuma ku-32GB, amakhadi e-SDXC aqala ku-64GB futhi angakhuphukela ku-2TB omkhulu kakhulu endaweni yokugcina. Lokhu kugxuma kwekhono lokulondoloza kwenziwa nokwenzeka ngokusebenzisa uhlelo lwefayela le-exFAT, elisekela osayizi bamafayela amakhulu namavolumu uma kuqhathaniswa nohlelo lwe-FAT32 olusetshenziswa emakhadini e-SDHC. Ifomethi ye-SDXC inenzuzo ngokukhethekile ekuthwebuleni izithombe ezinesinqumo esiphezulu, ukuqoshwa kwevidiyo ye-4K, kanye nezidingo ezibanzi zokugcinwa kwedatha.
Lisebenza kanjani ikhadi le-SDXC?
Ukusebenza kwekhadi le-SDXC kusekelwe ekwakhiweni kwalo kanye nobuchwepheshe obuyisisekelo. Amakhadi e-SDXC asebenzisa inkumbulo ye-flash ye-NAND, uhlobo lwesitoreji esingaguquguquki esingadingi amandla okugcina idatha. Lobu buchwepheshe buvumela isivinini esisheshayo sokufunda nokubhala, esibalulekile emisebenzini efana nokurekhoda ividiyo ye-4K noma ukudlulisa amafayela amakhulu. Ukwengeza, amakhadi e-SDXC afakwe isistimu yokulinganisa yekilasi lesivinini ebonisa ubuncane bezinga lokusebenza lokuqoshwa kwevidiyo. Isigaba se-UHS (Isivinini Esiphezulu) siqhubeka sithuthukisa lezi zilinganiso, sinikeza imininingwane emandleni ekhadi ngokuya ngemisebenzi elandelanayo yokufunda nokubhala, ebalulekile ekuphathweni kwedatha enesivinini esikhulu.
Izinzuzo kanye nezithiyo zekhadi le-SDXC
Inzuzo eyinhloko yamakhadi e-SDXC amandla awo okugcina amakhulu, okuyinzuzo kubathwebuli bezithombe abangochwepheshe, abathwebuli bevidiyo, nanoma ubani onezidingo ezibalulekile zesitoreji sedijithali. Ngaphezu kwalokho, ukusebenza ngesivinini esiphezulu kwamakhadi e-SDXC kuwenza alungele ukurekhoda ividiyo enencazelo ephezulu, ukudlala emuva okuqukethwe kwe-HD, nokwenza ukudluliselwa kwamafayela okusheshayo. Nokho, kunezihibe okufanele zicatshangelwe. Isistimu yefayela ye-exFAT, nakuba iguquguquka, ingase ingasekelwa amadivayisi amadala noma amasistimu okusebenza, ikhawulela ukuhambisana. Ukwengeza, umthamo omkhulu wamakhadi we-SDXC uza ngenani eliphakeme uma kuqhathaniswa namakhadi e-SDHC, okuwenza abe utshalomali olubaluleke kakhulu.
Ungalikhetha kanjani ikhadi le-SDXC
Ukukhetha ikhadi elifanele le-SDXC kuhlanganisa ukucabangela izinto ezimbalwa, okuhlanganisa umthamo, isivinini, ukuqina, nokuhambisana. Amandla kufanele akhethwe ngokusekelwe ezidingweni zakho ezithile zokulondoloza, kukhumbula izidingo zesikhathi esizayo. Isivinini singesinye isici esibalulekile, ikakhulukazi emisebenzini ehlanganisa ukuqoshwa kwevidiyo enesinqumo esiphezulu noma ukuthwebula izithombe eziqhumayo. Bheka amakhadi anesigaba sesivinini se-UHS ukuze uqinisekise ukusebenza kahle. Ukuqina kubalulekile kubasebenzisi abadalula amakhadi abo ezimeni ezimbi kakhulu, ngamanye amakhadi anikeza izici zokuvikela amanzi, ukushaqeka, nezici zobufakazi be-x-ray. Okokugcina, qiniseka ukuthi ikhadi liyahambisana nedivayisi yakho, uhlole kokubili ukusekela komthamo omkhulu wedivayisi kanye nesistimu yefayela.
Ungalisebenzisa kanjani ikhadi le-SDXC
Ukusebenzisa ikhadi le-SDXC kuqondile, kodwa kunezinqubo ezingcono kakhulu zokuqinisekisa ubuqotho bedatha nokusebenza okuphelele. Hlala ufometha amakhadi amasha e-SDXC ocingweni lwakho ngaphambi kokuwasebenzisa, njengoba lokhu kuzolungisa ikhadi ngokwezidingo eziqondile zocingo. Qaphela ukuphathwa kwedatha, njalo wenze isipele samafayela abalulekile ukuze uvimbele ukulahleka kwedatha. Lapho udlulisela idatha phakathi kwamadivayisi, sebenzisa isifundi sekhadi esinedumela elihle noma uxhumano oluqondile ukuze unciphise ingcuphe yenkohlakalo. Ukwengeza, gcina ikhadi lakho le-SDXC endaweni eyisivikelo lapho lingasetshenziswa ukulivikela ekulimaleni ngokomzimba nasezicini zemvelo.
Isiphetho:
Amakhadi e-SDXC amelela intuthuko enkulu ekugcinweni kwedijithali, enikeza umthamo ongenakuqhathaniswa nokusebenza kwezinhlelo zokusebenza eziningi. Ukuqonda ukuthi zisebenza kanjani, izinzuzo zazo kanye nemikhawulo yazo, nokuthi ungazikhetha kanjani futhi uzisebenzise kanjani kungathuthukisa ulwazi lwakho lwedijithali, kuqinisekise ukuthi wenza okuhle ngamadivayisi akho edijithali. Kungakhathaliseki ukuthi ungumthwebuli wezithombe ochwepheshe, umthwebuli wevidiyo, noma umane nje ungumuntu odinga isitoreji sedijithali esibanzi, ikhadi le-SDXC lingaba isengezo esibalulekile kunqolobane yakho yobuchwepheshe.
