Gore rino, ichitevera Toshiba, WDC uye Seagate yakatanga kugadzira madhiraivha ane 9 magineti ndiro. Izvi zvakave zvinogoneka nekuda kwekuuya kwezvose zviri zviviri mahwendefa matete uye shanduko kune yakavharwa mabhuroko ane mahwendefa umo mweya unotsiviwa nehelium. Iyo yakaderera density yehelium inoisa mutoro wakaderedzwa pamahwendefa uye inotungamira kukudzikisira kushandiswa kwemagetsi nema spindle rotation motors. Nekudaro, kugona kwemadhiraivha eHDD kwatora imwe nhanho kumberi - kusvika ku16-18 TB kana iri nyaya yekurekodha yakajairwa perpendicular uye kusvika ku18-20 TB kana uchishandisa "matairi" kurekodha emhando yeSMR. Zvino maonero akapatsanurwa ...
Sekureva kweWestern Digital, kambani iyi icharamba ichiwedzera huwandu hwema hard drive nekuchinja kune maplatter ane microwave-anobatsira kurekodha (MAMR), uye Seagate nekugadzirisa tekinoroji kutsigira kupisa kwenzvimbo kwemagineti kurekodha (HAMR). Yakaburitswa nerutsigiro rweMAMR . Iye aripo kana kuti haapo. Uye kutyaira neHAMR yekuburitswa kwevanhu vakawanda muhafu yekutanga ye2020 nenzira yenguva dzose gumi nemasere TB HDD uye makumi maviri TB ine SMR. Asi pane pfungwa yechitatu. Iri muchokwadi chekuti hard drive ine MAMR uye HAMR kusvika 2022, uye seimwe nzira, muna 2021 maHDD ane gumi akajairwa magineti ndiro achaonekwa akawanda.
Sekureva kweTrendfocus vanoongorora, WDC neSeagate vari kushanda mukugadzira gumi-ndiro hard drives. Nyanzvi dzinodaidza kunonoka kuchinjika kwemadhiraivha ane SMR tekinoroji mune niche yeinonzi pedyo-HDD chinhu chinodiwa pakubuda kwemidziyo yakadaro. Nearline kirasi hard drives ane conditional buffer pakati inononoka dhisiki chengetedzo uye RAM (kana, neimwe nzira, pakati pe caching arrays uye disk kuchengetedza). Tekinoroji yeSMR inoda nguva yekurekodha data nekuti inosanganisira kupindirana kwemateki. Vavaki ve disk arrays vanozeza kutora SMR modhi uye vangagamuchira nemufaro maHDD akajairwa ane hukuru hukuru.
Sekureva kweTrendfocus, kudiwa kwakaderera kwema SMR modhi uye isina kuchena MAMR/HAMR matekinoroji anomanikidza vagadziri kuti vatarise kugadzirwa kweHDD neyakajairwa kurekodha. Mune mamwe mazwi, kubva kutanga kwa2020, gumi nemasere TB HDDs ane perpendicular kurekodha uye 18 maplatter achagadzirwa akawanda aine shanduko kuenda ku9 TB HDDs ane SMR kusvika kumagumo a20, uye kubva 2020 2021 TB HDDs ane gumi ndiro achatanga kuburitswa, kuchiteverwa nekuburitswa muna 20 kweakawanda capacious HDDs ane MAMR/HAMR tekinoroji pasina SMR.
