SDHC Memory Cards: umlando ukuthuthukiswa nezici zobuchwepheshe

Phakathi impumelelo flash inkumbulo amazinga ekhona wanamuhla wembulunga yonke emakethe - SD. Omunye ethandwa kakhulu izinhlobo zawo - SDHC. Ngesisekelo emhlabeni olufanele anothile ubuchwepheshe nemikhiqizo ukukhiqiza ngokwanele olunzulu nethembeke imemori khadi. Yiziphi izici ejwayelekile? Njengoba kwaba khona kumadivayisi abambisana SDHC?

Ngokucacile SDHC ikhadi

SDHC imemori khadi (noma Secure Digital Umthamo High) amadivayisi ukuthi usebenza standard, okuyinto eyaba okwengeziwe ekuthuthukiseni ubuchwepheshe flash inkumbulo uhlobo le-SD, akhiwa SD Card Association. I engavamile kulezi amadivaysi - ukuthi amandla abo ongafinyelela-32 GB. Uhlelo ifayela, okuyinto avame ukusetshenziswa kumemori amakhadi afana - FAT32.

Omunye amazinga lapho zingaba SDHC imemori khadi - micro. Kodwa kulokhu, ndawonye ngedivayisi, njengoba umthetho, kubalulekile ukusebenzisa SD-adaptha, okuyothi ngalo uxhumano PC noma enye idivayisi, alisebenzisa flash inkumbulo.

Ngokuvamile iza izikhwebu ne amamojuli inkumbulo ejwayelekile micro.

ukuhambisana

Kufanele kuqashelwe ukuthi efanele esezingeni SDHC imemori khadi hleze ingahambisani ngedivayisi ukuthi ekuqaleni eklanyelwe ukusebenza ezivamile SD-amakhadi. Iqiniso ukuthi abathintekayo isimiso encike ekhuluma (efana nama-hard drive), njengoba kuqhathaniswa ibhayithi ukuthi ukusebenza isizukulwane esedlule sakwa-khadi.

ukuthuthukiswa Umlando SD-ikhadi

Ngaphambi global IT-onjiniyela lakhiwe olusekela SDHC ejwayelekile imemori khadi, ke kwandulelwe ukugunyazwa okwenziwe umsebenzi eside futhi esihleliwe brand eziholela embonini elifanele futhi ukwandisa nezimo amadivayisi flash esetshenziselwa ukugcina amafayela. Ngakho, ngo-1999, inkampani SanDisk, Toshiba, futhi Matsushita sinqume kusungula lizinga entsha - SD, noma Digital Secure. Yayiyini ngokucacile yayo?

Okokuqala, ekusekeleni DRM ngokuhambisana nenqubo ye SDMI. Ngokwe umqondo ehlongozwayo ngu brand amathathu ashiwo ngenhla, i-SD-format imemori khadi kwakufanele bancintisane emakethe ayesevele aziwa Sony Memory Stick ubuchwepheshe. Three sha wadala inhlangano entsha ebizwa nge-SD Assiciation. Ngemva kwalokho, ngo-isakhiwo sawo sibandakanya brand ezinkulu - ezifana, isibonelo, Intel, AMD, Samsung, Apple.

Ubuchwepheshe ngqa isebenze SD 1.0, uyakwazi ukubeka idatha ku ivolumu ku-2 GB, kwesibili - SD 1.1, usebenza ngaphansi kwenkululeko amafayela kufika ku-4GB. Umkhawulo, esibonakala by imemori khadi SDHC - 32GB. Isizukulwane esisha se-flash inkumbulo - I-SDHX ejwayelekile, angazamukela up 2 terabytes amafayela.

Ukusebenzisa le-SD-amakhadi kanye nalezo ukusekela ejwayelekile SDHC ezihlukahlukene izicelo ubuchwepheshe digital. Isobho Ifanele ingase icele njengabathwali bendlu cishe zonke izinhlobo amafayela. ukusebenza emangalisayo-aspect kokusebenzisa ukuba Photo futhi okokusebenza kwevidiyo. SD-amakhadi ayatholakala, okuthembekile. Isobho, abasebenza SDHC ubuchwepheshe - nazo elinesimo umthamo ehloniphekile.

benza amakhadi SDHC kanjani?

Indlela Kwathi emakethe SDHC imemori khadi IT-amadivayisi? Amadivayisi yokuqala ukusebenza standard SD, njengoba sibonile ngenhla, zazihambisa ngokwako kuphela ku-2 GB kwemininingwane. Kwaphela isikhathi eside le nsiza ngokwanele ukwenza eziyisisekelo imisebenzi umsebenzisi - ezifana ukubeka imibhalo yakho, izithombe, umculo amafayela.

Kancane kancane izidingo abanikazi amakhompyutha anda. Ngo-2006, entsha, indinganiso kangcono flash inkumbulo - SDHC. Ngawo lowo nyaka inkampani futhi SD Associations itfutfukise amakilasi ngenxa ijubane amadivayisi ahambelanayo. Phakathi kwazo ngazinye lezinto fixed inani eliphansi isivinini (e MB / s) amafayela Ukufundwa noma ukubhala.

SDHC khadi, ngokuvamile ukubhekana kangcono nale imisebenzi umsebenzisi. Nokho, izidingo abathanda of electronics digital laqhubeka landa. Ngakho lapho SDXC ejwayelekile, kuhilela nokubekwa up 2 TB amafayela. Nakuba, kufanele kuphawulwe, emakethe evulekile amadivayisi efanayo awatholatholakali futhi iyabiza (eshibhile, njengoba umthetho, ukuthenga i wangaphandle hard drive).

Uhlelo ifayela efakwe kwi entsha SD-amakhadi - exFAT, FAT32 baba ukuqhubeka. Phakathi izinzuzo enkulu indinganiso entsha ehlongozwayo ngu-Microsoft - nokuncipha umfutho ngaphezulu idatha kwelinye wemboni.

Indlela ukukhetha elikhulu SD-ikhadi?

Kwezinye izimo, ngaphambi abasebenzisi PC kungaphinde kube yinkinga, kungcono uthenge - SDHC iMemori Khadi noma, isibonelo, idivayisi SDXC ejwayelekile? Konke kuncike ngokuyinhloko oyifunayo kudivayisi umthamo. Omunye umbandela - nekhompyutha ehambisanayo noma enye idivayisi ne nomgomo ofanele. Iqiniso lokuthi amadivaysi - amakhamera, ama-PC abafundi ikhadi, imodeli kudala njalo osekelwa flash inkumbulo, eyakhishwa ngo-ubuchwepheshe entsha. Ngesikhathi esifanayo, kuyaphawuleka ukuthi ukusekela labo noma ezinye izindinganiso kungaya hhayi kuphela izici zezingxenyekazi zekhompyutha devaysa, kodwa futhi ku inguqulo yakho ye-firmware kuso. Kungenzeka ukuthi i-okufakwa kubuyekeze elula kuzosiza idivayisi - ngokwesibonelo, iseli esifanayo, sifunde ukuqaphela SDHC noma SDXC imemori khadi yakamuva.
