Ngokuqinisekile ubonile amakhadi amaningi ememori ehlukahlukene futhi wazibuza: ahluke kanjani? Izici eziningi kanye nomkhiqizi wedivayisi mhlawumbe idatha ebaluleke kunazo zonke ekushayeleni kwalolu hlobo. Kulesi sihloko, impahla yabo njengeklasi yejubane izocatshangelwa ngokuningiliziwe. Ake siqale!

Isigaba sejubane lememori khadi
Iklasi yiparamitha ekhomba ijubane lokushintshanisa ngolwazi phakathi kwememori khadi kanye nedivayisi lapho efakwe khona. Ukuphakama kwejubane lokushayela, ngokushesha kuzothathwa izithombe namafayela evidiyo, futhi kuzoba namabhuleki amancane lapho evuliwe futhi edlalwa. Kusukela namuhla kunamakilasi angu-3, okuyilowo nalowo angase abe nesici esihlukile, inhlangano ye-SD Card Association yomhlaba wonke (ngemuva kwalokhu ebizwa ngokuthi yi-SDA) ihlongoze ukumaka izici ezithile zekhadi lememori le-SD ngqo kulokho. Amakilasi anikezwa ngegama le-SD Speed Class futhi njengamanje afaka: I-SD Class, UHS ne-Class Class.
Ngenxa yalesi sixazululo, noma ubani ofuna ukuthenga idrayivu encane angabheka kuphela amaphakethe ayo esitolo futhi athole ulwazi olubanzi mayelana nesivinini saso. Kodwa kufanele uhlale uqaphele, ngoba abanye abakhiqizi abangenangqondo, abhala ikhadi, bangase bakhumbule ijubane lokufunda kusuka kudivayisi, kunokuba babhale kulo, okuphikisana nesinqumo se-SDA futhi badukisa. Ngaphambi kokuthenga, bheka imiphumela yokuhlola ku-inthanethi noma hlola idrayivu ngokuqondile esitolo, ucele mayelana nalomsizi wokuthengisa. Ukusebenzisa isofthiwe ekhethekile, ungabheka amakhadi athengiwe kakade kukhompyutha yakho.

Bhala amaklasi okusheshisa
I-CD Class, i-UHS ne-Class Class kukhona amazinga okurekhoda kumemori khadi. Inombolo ekhonjiswe eceleni kwesifingqo yi-value yesilinganiso esincane esingenzeka sokuqopha idatha kudivayisi ngaphansi kwezimo zokuhlola ezimbi kakhulu. Le nkomba ibalwa ku-MB / s. Okuthandwa kakhulu yi-SD Standard Standard kanye nokuhluka kwayo, nge-multiplier kusuka ku-2 kuya ku-16 (2, 4, 6, 10, 16). Emadivaysi, kuboniswa njengencwadi yezinhlamvu zesiLatini "C", ngaphakathi enombolweni. Leli nani lizothatha ukubhala ngokushesha.
Ngakho-ke, uma unenombolo engu-10 ebalazweni encwadini "C", khona-ke ijubane kufanele okungenani libe ngu-10 MB / s. Isinyathelo esilandelayo ekuthuthukiseni amazinga okusheshisa ama-UHS. Emakhadini amemori, ichazwa njengencwadi ethi "U", equkethe inani lamaRoma I noma III, noma amanye ama-Arabhu. Kuphela manje, ngokungafani neKlasi le-SD, inombolo ebusweni kufanele yande nge-10 - ngaleyo ndlela uzokwazi isici esidingekayo.
Ngonyaka we-2016, i-SDA yafaka isichazamazwi esheshayo kuze kube yimanje - i-V Class. Ihambise ukusuka ku-6 kuya ku-90 MB / s, kuye ngokuphindaphindiwe. Amakhadi asekela lo mgangatho amakwe ngencwadi ethi "V", elandelwa inombolo. Yandisa leli xabiso ngo-10 futhi u-voila-manje sesiyazi isivinini esibhaliwe sokubhalela le drive.
Kubalulekile: Enye imemori khadi ingase isekele eziningana, kuze kube yizingu-3, amazinga okusheshisa, kodwa akuwona wonke amadivaysi angasebenza namazinga ngokushesha kunesigaba se-SD.
Amakilasi we-SD (C)
Amakilasi we-SD akhula ekuqhubekisweni kwe-arithmetic, okuyi-2. Okubukeka ngayo emzimbeni wekhadi.
- I-SD Class 2 inikeza isivinini okungenani okungu-2 MB / s futhi yenzelwe ukurekhoda ividiyo ngesinqumo se-720 by 576 pixels. Le fomathi yevidiyo ibizwa nge-SD (incazelo ejwayelekile, ukuba ingadideki nge-Digital Secure - leli yigama lefomethi yememori khadi ngokwayo) futhi isetshenziswe njengendlela evamile kumabonakude.
- I-SD Class 4 no-6 yenza kube lula ukurekhoda okungenani okungu-4 no-6 MB / s, ngokulandelana, okuzokuvumela ukuthi usuvele ubhekene nevidiyo ye-HD ne-FullHD. Leli klasi lihloswe ngamakhamera wesigaba sokuqala, ama-smartphone, izidakamizwa zemidlalo namanye amadivayisi.
Zonke amakilasi alandelayo, kuze kube yi-UHS V Class, mayelana nokuthi yiluphi ulwazi oluzokwaziswa ngezansi, ukuvumela ukuba ubhale idatha ekushayeleni ngokushesha futhi ngokuphumelelayo ngokwengeziwe.
UHS (U)
I-UHS yisifushaniso samazwi esiNgisi esithi "Isivinini se-Ultra High", esingasetshenziswa ngesiRashiya ngokuthi "Isivinini se-Ultra High." Ukuthola isivinini sokubhala esincane kunazo zonke sokubhala idatha ukushayela ngaleli klasi lejubane, ukwandise inombolo ekhonjisiwe kumacala abo ngo-10.
- I-UHS 1 yenzelwe ukudubula okuphezulu kwevidiyo ye-FullHD nokuqopha ukusakaza okubukhoma. Isivinini esithembisiwe sokulondoloza ulwazi ekhadini okungenani ngu-10 MB / s.
- I-UHS 3 iklanyelwe ukurekhoda amafayela wevidiyo angu-4K (UHD). Isetshenziswe kusibuko nakamakhamera angenasipiliyoni sokudubula ividiyo ku-UltraHD no-2K.
Isigaba sevidiyo (V)
Igama elifingqiwe yi-V Class futhi lafakwa kwi-SD Card Association ukuqoka amabalazwe alungiselelwe ukurekhoda amavidiyo amathathu namafayela namaqhinga ka-8K noma ngaphezulu. Inombolo emva kwencwadi "V" ibonisa inombolo ye-MB / s eqoshiwe. Isivinini esiphansi samakhadi nalesi sivinini sejubane singu-6 MB / s, okuhambisana neklasi ye-V6, futhi isigaba esiphakeme njengamanje ngu-V90 - 90 MB / s.
Isiphetho
Lesi sihloko sibuyekeze amakilasi angu-3 okusheshayo amakhodi amememori angaba nawo - I-SD Class, UHS ne-Class Class. I-SD Class iklanyelwe ukusetshenziselwa kabanzi emaqhinga ahlukahlukene, kuyilapho ezinye amakilasi zenzelwe uhla oluncane lwemisebenzi. I-UHS izokuvumela ukuba urekhode ividiyo ngokuphumelelayo kufomethi kusuka ku-FullHD kuya ku-4K futhi uphinde usakaze ukusakazwa ngesikhathi sangempela, okwenza kube ngumgomo wamakhamera aphansi. Iqoqo levidiyo lakhiwa ukuze ulondoloze amafayela amakhulu wevidiyo ngesinqumo sika-8K, kanye nevidiyo engu-360 °, eyayizilungiselele ububanzi bayo bokusebenza - imishini yobuchwepheshe neyabizayo.
