Kule mihla yedijithali, ikhadi le-SD lisebenza njengeyona nto ibalulekileyo ekwandiseni amandla okugcina izixhobo zethu. Nokuba yeye-smartphone, ikhamera yedijithali, okanye nasiphi na esinye isixhobo sombane somthengi, ukuqonda iinuances zamakhadi e-SD kunokuphucula kakhulu amava akho omsebenzisi. Eli nqaku lijolise ekunciphiseni ubunzima obujikeleze amakhadi e-SD, ukuphula iindidi zabo, amandla, iiklasi zesantya, ukuhambelana, kunye neengcebiso zokulondoloza kwiingcamango ezigayiweyo. Sijoyine njengoko sijonga kwihlabathi elintsonkothileyo lamakhadi e-SD, sikuxhobisa ngolwazi lokwenza izigqibo ezizizo.

Ukuqonda iintlobo zekhadi le-SD kunye nezakhono
Amakhadi e-SD aza kwiindidi ezahlukeneyo kunye namandla, abonelela kwiimfuno ezahlukeneyo zokugcina. Iintlobo ezintathu eziphambili zamakhadi e-SD yi-SD (i-Digital eKhuselekileyo), i-SDHC (i-Digital High Capacity ekhuselekileyo), kunye ne-SDXC (uKhuseleko lwe-Digital Extended Capacity). Ngelixa amakhadi e-SD anikezela ngogcino ukuya kuthi ga kwi-2GB, amakhadi e-SDHC aqala kwi-2GB ukuya kwi-32GB, kwaye amakhadi eSDXC anikezela ukusuka kwi-32GB ukuya kwi-2TB. Olu luhlu luqinisekisa ukuba nokuba ungumsebenzisi oqhelekileyo ogcina iifoto kunye namaxwebhu okanye uchwephesha wevidiyo ofuna indawo eyaneleyo yeevidiyo ze-4K, kukho ikhadi le-SD lakho.
Ukukhetha umthamo ofanelekileyo kubalulekile njengoko kuchaphazela ngokuthe ngqo amandla okugcina isixhobo sakho. Nangona kunjalo, kubalulekile ukuba ungaqwalaseli nje ubungakanani bogcino kodwa nohlobo lweefayile ojonge ukuzigcina. Imifanekiso enesisombululo esiphezulu kunye neevidiyo, umzekelo, zifuna indawo eninzi kunamaxwebhu abhaliweyo. Ke ngoko, kuyacetyiswa ukuba uvavanye iimfuno zakho zogcino phambi kokuba uthenge.
Ngaphezu koko, ukuvela kwamakhadi e-SDUC (i-Secure Digital Ultra Capacity), eyandisa isitoreji ukuya kwi-128TB, ibonisa ukuguquka okuqhubekayo kwiteknoloji yokugcina, ethembisa ukukhawulelana neemfuno zedatha ezikhulayo zezixhobo ezizayo.
Ukucacisa iiklasi zesantya sekhadi le-SD kunye nokubaluleka kwazo
Iklasi yesantya yenye into ebalulekileyo xa ukhetha ikhadi le-SD, njengoko lichaphazela amazinga okudlulisa idatha. Udidi lwesantya luboniswa ngenani elingaphakathi kwesangqa ekhadini, elimele ubuncinci besantya sokubhala kwiimegabytes ngesekhondi (MB/s). Iiklasi ziqala kwiKlasi 2 (2MB/s) ukuya kwiKlasi 10 (10MB/s). Ukufumana imisebenzi enzima kakhulu njengokurekhoda ividiyo ephezulu-definition, iiklasi ze-UHS (i-Ultra High Speed) zibonelela ngesantya esikhawulezayo, kunye ne-U1 kunye ne-U3 inikezela ngesantya esincinci sokubhala se-10MB / s kunye ne-30MB / s, ngokulandelanayo.
Ukuqonda ezi klasi zesantya kubalulekile, ngakumbi kubafoti kunye nabathwebuli bevidiyo, njengoko ukukhetha ikhadi elinesantya esinganelanga kunokubangela ukulahlwa kwezakhelo okanye ixesha lokudlulisa iifayile. Umzekelo, ukurekhoda ividiyo ye-4K kufuna ubuncinci iklasi yesantya ye-U3 ukuqinisekisa ukurekhodwa kakuhle ngaphandle kokulahleka kwedatha.
Ukongeza, iklasi ye-V yamva nje, eyenzelwe ukurekhodwa kwevidiyo, ibonelela ngesantya esiphezulu. I-V6, i-V10, i-V30, i-V60, kunye ne-V90 ihambelana nesantya esincinci sokubhala se-6, i-10, i-30, i-60, i-90MB / s, ngokulandelanayo, ukulungiselela iimfuno zokurekhodwa kwevidiyo ye-professional-grade kunye ne-high-resolution photography.
Iingqwalasela zokuhambelana kwamakhadi e-SD
Ngelixa amakhadi e-SD ehambelana ngokubanzi nezixhobo ezahlukeneyo, izinto ezithile kufuneka ziqwalaselwe ukuqinisekisa ukusebenza kakuhle. Okokuqala, owona mda uphezulu womthamo wesixhobo ubalulekile. Umzekelo, isixhobo esidala sinokungawaxhasi amakhadi eSDXC, sinciphisa ukusetyenziswa kwamakhadi e-SD kunye ne-SDHC. Ukungahoyi le miba yokuhambelana kunokubangela ukuba ikhadi lingaqatshelwa okanye lingasebenzi kakuhle.
Ngaphaya koko, ifomathi yesistim yefayile idlala indima ebalulekileyo ehambelanayo. Ngelixa amakhadi e-SD kunye ne-SDHC ngokuqhelekileyo asebenzisa inkqubo yefayile ye-FAT32, amakhadi e-SDXC kunye ne-SDUC asebenzisa i-exFAT, eyenzelwe ukuphatha iifayile ezinkulu kunye namandla. Izixhobo ezingaxhasi i-exFAT zinokufuna ukuhlengahlengiswa kwekhadi kwisixokelelwano sefayile ehambelanayo, okunokuthintela ukusebenza okanye umthamo walo.
Kukwafanelekile ukuba uqaphele ukuba ezinye izixhobo, ngakumbi iikhamera kunye nee-smartphones, zinokuba neengcebiso ezithile kwiiklasi zesantya sekhadi le-SD ukuqinisekisa ukusebenza kakuhle. Ukubonana nencwadana yesixhobo okanye iwebhusayithi yomenzi kunokubonelela ngesikhokelo esibalulekileyo ekukhetheni elona khadi le-SD lihambelanayo.
Iingcebiso zokugcina ikhadi lakho le-SD
Ukugcinwa ngendlela eyiyo kwekhadi lakho le-SD kubalulekile ukuze uqinisekise ubomi obude kunye nokuthembeka. Okokuqala nokuphambili, ukusebenzisa inqaku elithi "susa ngokukhuselekileyo i-hardware" ngaphambi kokukhupha ikhadi kwikhompyuter kunokuthintela ukonakala kwedatha. Ukongeza, ukugcina ikhadi le-SD kude namaqondo obushushu agqithisileyo, ukufuma, kunye nemagnethi inokukhusela ingqibelelo yayo.
Ukuxhasa rhoqo idatha esuka kwikhadi lakho le-SD kwikhompyuter okanye kwindawo yokugcina ilifu nako kubalulekile. Lo mkhwa awukhuseli kuphela iifayile zakho kwilahleko yedatha enokubakho kodwa ikwavumela ulawulo lwedatha olulula kunye nokufunyanwa.
Okokugqibela, ukufomatha ikhadi lakho le-SD ngaphakathi kwesixhobo osisebenzisayo kuqala kunokuphucula ukusebenza. Eli nyathelo liqinisekisa ukuba ikhadi likwifomathi yefayile yefayile yesixhobo, enokunciphisa imiba enxulumene nokuhambelana kunye nokuthembeka kwedatha.
Ukukhangela ukuthengwa kwekhadi le-SD
Xa kuziwa ekuthengeni ikhadi le-SD, elixhotyiswe ngolwazi lweentlobo, amandla, iiklasi zesantya, kunye nokuqwalaselwa kokuhambelana, unokwenza isigqibo esinolwazi esizifaneleyo iimfuno zakho. Khumbula ukuvavanya iimfuno zakho zogcino, ukuhambelana kwesixhobo, kunye nezantya zogqithiso lwedatha olufunekayo ukuze ukhethe ikhadi le-SD elinikezela ngeyona ndlela ilungileyo phakathi kokusebenza kunye neendleko.
Ngaphezu koko, ukucinga ngeemfuno zexesha elizayo kunokonga ixesha nemali ekuhambeni kwexesha. Ukukhetha ikhadi elinomthamo ophezulu kancinane okanye isantya esingaphezulu kunesiyimfuneko ngoku kunokwamkela inkqubela phambili yekamva leteknoloji kunye neemfuno zedatha.
Ukuqukumbela, ukuqonda ubucukubhede bamakhadi e-SD kunokuphucula kakhulu amava akho ngezixhobo zedijithali. Ngokuqwalasela iintlobo, amandla, iiklasi zesantya, ukuhambelana, kunye neengcebiso zokugcina ezixoxiwe, unokukhetha kwaye ulawule ikhadi le-SD elihlangabezana neemfuno zakho zokugcina ngokufanelekileyo. Khumbula, ukhetho olunolwazi luhlala lolona khetho lulungileyo xa ujonga izinto ezintsonkothileyo zombane wabathengi.
