Mazuva ano microSD memory card

Nhasi ruzivo rwemashoko rwuri kuwedzera. Vanhu vanoda nzvimbo dzakachengetedzwa dzekutsvaga, uko iwe unogona nyore nyore uye nokukurumidza kuisa huwandu hwemashoko. Zvimwe zvinodiwa zvinosangana nevanjiniya kubva kumakambani anotungamira avo vari kugara vachiedza kuwana mhinduro kumubvunzo uyu.

Kunyanya chaizvo, mhinduro yacho yatowanikwa, uye basa iri kuitwa kuvandudza izvo zvatove zviripo. Chinyanya kuzivikanwa ikozvino chichiyeuchidza, chinoshandiswa kwose kwose. Kunyange zvazvo madhizimisi akaoma anoramba achikosha, mafambisi epfuuriro anoramba achienderera mberi kwose kwose kumusika. Iye zvino microSD memori khadi inoshandiswa munharaunda dzose, "mhepo inofambisa" inenge yakatsinhanisa zvachose DVD-RW nedzimwe dhi rekodha.

Iye zvino varairi vamira kurega kutarisa teknolojia ye compact discs, sezvazvaiva kare. Nokuti chido ichi chiri kukura. Izvo chete ndeyekwanisi yekunyora vhidhiyo mune tsanangudzo yakakwirira, nokuda kwekushandisa iyi Blue-Ray media. Kana zvisina kudaro, microSD memori khadi inogona kuita nyore mamwe mabasa ose nyore.

Urongwa hwezvigadzirwa hunenge husingagumi, kubva pafoni uye mafoni emazuva ano, uye kupedzisa nemichina yakasiyana-siyana uye yakadzika-bhanhire, somuenzaniso, vafambisi vezvikepe.

Iyo microSD memory card inoshandiswawo mumakamera akawanda, kusanganisira unyanzvi hweS SLR makamera dzinoda kuwanda kwekuchengetedza kwemafananidzo ekugadzirisa zvakakwirira. Makadhi okuyeuka anogadzirwa achifungisisa izvi zvinoda.

Nhoroondo yezvisikwa

Nhoroondo, sezvakaitika mumatambudziko akawanda ane zvigadzirwa zvekuchengetedza deta, yakatanga nekugamuchirwa kwezinga rimwe chete. Kuita izvi, zvakanga zvakafanira kubatanidza kuedza kwemakambani makuru akakura aifanira kubvumirana pane izvi.

Muna 1999, nheyo yeSsecure Digital yakagamuchirwa, uye sampuli dzokutanga dzaipiwa nemutongi wayo ane kuchengetedzwa kwemagetsi kusinganzwisisi kuverenga nekunyora kwemashoko. Kudzivirirwa kwemashoko kwaiva panguva iyoyo chimwe chezvinhu zvinodiwa.

Nhamba yeDS yechizvarwa chekutanga yakabvumira kuita makadhi kusvika 2 GB. Pakazosvika mureza, izvi zvaive zvakakwana. Iyo yakavandudzwa version, iyo yakagamuchira kudanwa SD 1.1, yakabvumirwa kuita dhigiri kusvika 4 GB. Zvisinei, izvi zvakakurumidza kuva zvisina kukwana, saka shanho ye SDHC yakaonekwa kusvika kusvika 32 GB. Iye zvino chimiro chemashoko matsva - SDXC, inobvumira kugadzira memori makadhi, iyo inogona kusvika 2 Terabytes.

Technical specifications

Pasinei nezvimwe zvinhu zvakajairika, kadhi yemakemikari yemakemikari yemazuva ano Icho chakasiyana zvakasiyana neicho chaive makore anopfuura 10 akapfuura. Vanobatanidzwa chete nechiyero chimwe chete, chinogamuchirwa senheyo.

Makadhi eSADHC anoshandiswa zvakashandiswa, izvo zvinopesana kubva kune mumwe mumakirasi. Ikirasi yakaderera ndiyo yechipiri, inopa kukurumidza kunyora kusvika 2 MB / sec. Uye boka rakanakisisa remakadhi iSD Class 10, rinogona kunyora mashoko nokukurumidza, kusvika 10 MB / sec. Zvisinei, izvi hazvina kukwana kumagetsi ezuva ranhasi, saka vaiti vekare vakaramba vachienda. Semuenzaniso, kambani yemavhidhiyo yemazuva ano iyo inotora vhidhiyo mune tsanangudzo yakakwirira inodikanwa memori kadhi nemutambo wokurekodzisa wekuda 24 MB / sec.

Zvinyorwa zvakawanda zvakadaro zvinokonzera kuumbwa kwe memori kadi, kunyange izvi zvisingawanzodiwi. Zvisinei, iyo yakakwirira yekirasi, yakakwirira yekushanda nekadhi. Mune zvimwe zviitiko, ivo vakavimbika, saka mubvunzo wekuvandudza kemori kadi haingasimuki. Zvisinei, mitsva itsva inogadzirisa zvinetso kwete chete nehuwandu uye nekukurumidza kwebasa, asiwo nekuvimbika kwevatakuri ve data, iyo inoshandiswa munenge mapeji ose emazuva ano. Muchiitiko ichi, isu tiri kutaura pamusoro pebasa rekubatana kwevakiki ve teknolojia uye vadziki ve memori makadhi.
