Makhadi okumbukira SDHC: mbiri ya chitukuko ndi zinthu zamakono

Pakati pa miyezo yabwino kwambiri ya kukumbukira fungo, yomwe ilipo pamsika wamakono wapadziko lonse - SD. Mmodzi mwa mitundu yake yotchuka ndi SDHC. Malingana ndi zipangizo zoyenera, makampani oyendetsa dziko lapansi amapanga makadi okwanira okwanira komanso odalirika. Kodi ndi zinthu ziti zomwe zili muyeso iyi? Kodi zipangizo zothandizira SDHC zimawoneka bwanji?

Makamaka a makadi a SDHC

Makhadi okumbukira SDHC (kapena Secure Digital High Capacity) ndi zipangizo zomwe zimagwira ntchito molingana ndi muyezo umene wakhala patsogolo kwambiri kwa zipangizo zamakono monga SD, zopangidwa ndi SD Card Association. Chidziwitso cha zipangizo zimenezi ndikuti mphamvu zawo zingathe kufika 32 GB. Fayiloyi, yomwe imagwiritsidwa ntchito nthawi zambiri pamakhadi ofanana - FAT32.

Imodzi mwa miyezo yomwe SDHC-micro memory card ingapangidwe. Koma panopa, pamodzi ndi chipangizochi, monga lamulo, muyenera kugwiritsa ntchito SD-adapter, yomwe mumagwirizanitsa ndi PC kapena chipangizo china chomwe chimagwiritsa ntchito kukumbukira.

Kawirikawiri amabwera ndi makompyuta a memphati mumakina ochepa.

Kulumikizana

Tiyenera kukumbukira kuti khadi la memori lovomerezeka la SDHC silingagwirizane ndi zipangizo zomwe poyamba zinakonzedwa kugwira ntchito ndi makadi a SD. Chowonadi ndi chakuti mfundo yopezeka m'magulu (monga disk hard) ikukhudzidwa mmenemo, mosiyana ndi imodzi yokha, imene ikugwiritsidwa ntchito mu makadi a makadi a mbadwo wakale.

Mbiri ya kukula kwa makadi a SD

Asanayambe makina opanga malingaliro a dziko lapansi a SDHC, makhadi ovomerezeka a SDHC, adayambanso ntchito yayitali ndi yowonongeka pogwiritsa ntchito makampani opanga makina kuti ayesetse ndikukonzekera luso lamakina omwe amasungidwa. Choncho, m'chaka cha 1999, SanDisk, Toshiba, ndi Matsushita adaganiza zopanga zatsopano - SD, kapena Secure Digital. Chinali chiyani kwenikweni?

Choyamba, pochirikiza DRM motsatira ndondomeko ya SDMI. Mogwirizana ndi lingaliro lofotokozedwa ndi malembo atatu omwe tatchulidwa pamwambapa, makhadi a makadi a SD akuyenera kukwiyirana ndi Sony omwe akudziwika kale ndi makina ojambula. Mitundu itatu inakhazikitsa bungwe latsopano, lotchedwa SD Assistance. Pambuyo pake, mawonekedwe ake anaphatikizapo zazikulu zazikulu - monga, Intel, AMD, Samsung, Apple.

Mu teknoloji ya SD, mibadwo ikuluikulu ya makadiyi imatulutsidwa. Choyamba, kugwira ntchito pa teknoloji SD 1.0, imatha kuika deta mu volume mpaka 2 GB, yachiwiri - SD 1.1, ikugwira ntchito mu fayilo kukula mpaka 4 GB. Mtengo wa malire, womwe umadziwika ndi SDHC - 32GB mememati khadi. Mbadwo wotsatira wa kukumbukira kwachinsinsi - molingana ndi muyezo wa SDHX, ukhoza kusungira mpaka 2 TB maofesi.

Makhadi a SD omwe amagwiritsidwa ntchito ndi omwe akuthandiza SDHC yodalirika pogwiritsa ntchito njira zamakono zamakono. Zipangizo zoyenera zingagwiritsidwe ntchito ngati ogwira pafupifupi mtundu uliwonse wa fayilo. Zimapindulitsa kwambiri pogwiritsa ntchito chithunzi ndi zipangizo zamakanema. Makhadi a SD alipo, odalirika. Zida, kugwiritsira ntchito teknoloji ya SDHC - imadziwika ndi mphamvu zabwino.

Kodi makadi a SDHC amawoneka motani?

Kodi msika wa makadi wa memphati wa SDHC unawoneka bwanji pamsika? Zida zoyamba zikugwiritsidwa ntchito muyezo wa SD, monga tawonera pamwambapa, poyamba tinangokhala ndi ma digita 2 GB okha. Kwa nthawi yayitali gweroli linali lokwanira kuti agwire ntchito zofunikira - mwachitsanzo, kuyika zikalata, zithunzi, mafayilo a nyimbo.

Pang'onopang'ono, zosowa za makompyuta zinakula. Mu 2006, chithunzithunzi chatsopano chopita patsogolo kwambiri - SDHC. Mu chaka chomwecho, mabungwe a SD adakhalanso ndi makalasi angapo othamanga kwa zipangizozo. Mulimodzi mwa iwo, mlingo wochepa (mu MB / sec) unalembedwa powerenga kapena kulemba mafayilo.

Makhadi okumbukira SDHC, ambiri, kuthana ndi ntchito zosungidwa zomwe amagwiritsa ntchito. Komabe, zosowa za okonda magetsi zamakono zinapitiriza kukula. Kotero mndandanda wa SDXC unawoneka, ndikuwona kuyika kwa maofesi mu volume mpaka 2 TB. Ngakhale, ziyenera kuzindikirika, kugulitsa kotseguka zinthu zoterezi ndizosawerengeka komanso zotsika mtengo (monga wotsika mtengo, monga lamulo, kugula galimoto yangwiro).

Fayiloyi imayikidwa pa makadi a SD atsopano ndi exFAT, omwe athandizidwa patsogolo pa FAT32. Zina mwa ubwino watsopano wotsatiridwa ndi Microsoft ndi kuchepetsa kukula kwa chiwerengero cha deta mkati mwa gawo limodzi.

Kodi mungasankhe bwanji khadi lapamwamba la SD?

Nthawi zina, wogwiritsa ntchito PC angakhale ndi funso: ndi chiyani chomwe chiyenera kugula - makadi a makadi a SDHC kapena, mwachitsanzo, zipangizo za SDXC? Chilichonse chimadalira, choyamba, pa mphamvu yofunikira ya chipangizochi. Chotsatira china ndicho kugwirizana kwa kompyuta kapena chipangizo china chomwe chimafanana. Chowonadi ndi chakuti zipangizo - makamera, ma PC, owerenga makhadi, mawonekedwe akale samawathandiza kukumbukira kukumbukira, kumasulidwa pa zamakono zamakono. Pa nthawi yomweyi, zomwe zikuwoneka, kuthandizidwa kwa iwo kapena miyezo ina sikudalira kokha pa ntchito ya hardware ya chipangizo, komanso pa tsamba la firmware lomwe likugwiritsidwa ntchito. Zingakhale zosavuta kuti pulojekiti yosavuta ikhale yothandizira chipangizo - mwachitsanzo, kamera yomweyo, phunzirani kuvomereza makadi apamtima a SDHC kapena SDXC.
