Amakhadi enkumbulo ayithinteli yedatha ehambisanayo futhi enokwethenjelwa, ngenxa yokuthi okungenani, ukutholakala kwama-DVRs atholakalayo kungenzeka. Namuhla sizokusiza ukhethe ikhadi elifanele ledivayisi yakho.
Izinkomba zokukhetha iKhadi
Izici ezibalulekile zamakhadi we-SD, okudingekayo ukuze kusetshenziswe okujwayelekile kwerekhoda, kufaka izinkomba ezinjengokuhambisana (ifomethi esekelwayo, isigaba esivamile nesivinini), ivolumu nomkhiqizi. Cabanga ngabo bonke ngokuningiliziwe.
Ukuhambisana
Abaqophi bevidiyo banamuhla basebenzisa i-SD kanye / noma amakhadi we-microSD amazinga we-SDHC nama-SDXC njengamadivayisi wokugcina. Amanye amakhophi asebenzisa i-miniSD, kodwa ngenxa yokungabi nalutho kwalabo abathwali, abathandeki kakhulu.
Standard
Uma uqala ukukhetha ikhadi lwedivayisi yakho, funda ngokucophelela izinga lezindaba ezisekelwayo. Njengomthetho, amadivayisi amaningi aphansi arekhoda ividiyo ngekhwalithi ye-HD, ehambisana nesilinganiso se-SDHC. Kodwa-ke, uma ngabe idivaysi ihlanganisa i-FullHD yokurekhoda kwevidiyo, ngokuqinisekile idinga ikhadi elijwayelekile le-SDXC.
Fometha
Ifomethi ayibalulekile kangako: noma ngabe i-DVR yakho isebenzisa imemori yememori ephelele, ungathenga i-adapter ye-microSD bese usebenzise lesi samuva ngokujwayelekile.
Kodwa-ke, kulokhu, kufanele uqaphele: kungenzeka ukuthi umbhalisi udinga amakhadi we-SD, futhi ngeke isebenze nezinye izici zefomu ngisho nangaphakathi kwe-adaptha.
Bheka futhi: I-DVR ayiboni imemori khadi
Isigaba sokusheshisa
Amakilasi asemqoka okuba yi-DVRs asekela i-Class 6 ne-Class 10, ehambisana nesivinini esincane sokubhala idatha esingu-6 no-10 MB / s. Emadivaysi omkhakha wesamba ophezulu kunayo futhi ixhaswa nge-UHS, ngaphandle kokungeke kwenzeke ukurekhoda amavidiyo ngesinqumo esiphezulu. Kubhalisi bezindleko eziphansi ezinezixazululo zokusebenza eziyisisekelo se-VGA, ungakwazi ukuthenga ikhadi le-Class 4. Izici zezigaba zejubane zihlanganisiwe ngokuningiliziwe kulesi sihloko.
Umbhalo
Ividiyo ingenye yezinhlobo eziningi zezinombolo, ngakho-ke amadivaysi okurekhoda amadijithali, okuyi-rekhoda, kufanele ukhethe amashayeli akwaziyo.
- Ukuncipha okunethezeka kungacatshangwa nge-16 GB drive, elingana namahora angu-6 wevidiyo ye-HD;
- Okukhethwayo kungabizwa ngokuthi umthamo we-32 noma u-64 GB, ikakhulukazi kwividiyo ephezulu yokuxazulula (i-FullHD nokuningi);
- Amakhadi anamandla we-128 GB nokuningi kufanele athengwe kuphela kumadivayisi asekela ukuxazulula isikrini kanye nesivinini esikhulu sokurekhoda.
Umkhiqizi
Abasebenzisi ngokuvamile abakhathaleli kancane umenzi wememori khadi abazoyithenga: i-parameter yamanani ibaluleke kakhulu kubo. Kodwa-ke, njengokwenziwa komkhuba, amakhadi ayabiza kakhulu ezinkampanini ezinkulu (i-SanDisk, i-Kingston, i-Sony) ethembeke kakhulu kunezinkampani ezingaziwa kakhulu.
Isiphetho
Ukufingqa ngenhla, singathola inguqulo engcono kakhulu yememori khadi ye-DVR. Lokhu kuyisiteshi se-microSD esingu-16 GB noma i-32 GB (njengoba kunjalo noma nge-adaptha ye-SD), izinga elijwayelekile le-SDHC kanye ne-class 10 kusuka kumkhiqizi ohloniphekile.
