Pamusangano weSeagate wekota yekubika, mukuru wekambani akabvuma kuti kuendeswa kwe16 TB hard drives kwakatanga mukupera kwaKurume, izvo zvave kuedzwa nevadyidzani uye vatengi vemugadziri uyu. Madhiraivha anoshandisa laser-assisted magnetic wafer heat (HAMR) tekinoroji, sezvakataurwa nemukuru weSeagate, anoonekwa zvakanaka nevatengi: "Vanongoshanda." Asi makore mashoma apfuura kwaive nekutaura nezveiyo HAMR tekinoroji nezve kusavimbika kwayo kwakanyanya, uye vakwikwidzi veSeagate havana kukurumidza kuitora. Izvo zvinofanirwa kuverengerwa, zvisinei, kuti Seagate haisati yagadzirira kutengesa madhiraivha akadaro, uye kushandiswa kwekutengesa kweHAMR tekinoroji kuchatanga chete mushure mekuburitswa kwemakumi maviri eTB madhiraivha.
Kana iwe ukazvitarisa, Toshiba kwenguva yakareba yakatarisa pakuwedzera nhamba yemagineti mahwendefa mune yakaoma dhiraivha kesi, uye haana kukurumidza kuunza hutsva hwakadai seyakafanana "tiled" chimiro (SMR). Nekuda kweizvozvo, yakasvika pachikumbaridzo chekugona kwe16 TB neyemhando yepamusoro yemagineti maplate uye kana yasvika 18 TB pachikumbaridzo ndipo painozotanga kushandisa SMR, kunyangwe ichibvumirawo musanganiswa wemaplateti ane MAMR tekinoroji, iyo inosanganisira. kupesvedzera midhiya vachishandisa microwaves. Asi kuna Toshiba, kuisa magineti mapfumbamwe mune imwe 3,5 β³ fomu factor kesi idanho rakapfuura, uye kambani iri kufunga nezve kugadzira madhiraivha ane gumi remagineti ndiro.
Chido chaToshiba chekuwedzera kuwanda kwemagineti ndiro chakatoshanda sechinangwa chekunyomba kubva kuWestern Digital Corporation, iyo vamiriri pamusangano wekota wekutaura vakati madhiraivha ayo gumi nematanhatu eTB emagineti masere ane tekinoroji yeMAMR angave akachipa kugadzira kupfuura vanokwikwidza. zvigadzirwa. WDC ichagona nzira ye "tiled" pakuburitsa madhiraivha gumi nemasere eTB, ayo achaburitswa gore rino risati rapera. Pakugadzira madhiraivha ane huwandu hweanopfuura makumi maviri TB mumakore gumi anotevera, WDC haizoshandisa tekinoroji yeMAMR chete, asiwo maviri akazvimirira emusoro mayuniti (actuator).
Sarudzo yazvino iri kuitwa zvakare neSeagate, uye pamusangano wekota manejimendi akatsanangura kuti shanduko kuenda kumabhuroki maviri emusoro inogona kupa kuwedzera kwakakura mukumhanya kwekufambisa data, izvo zvinodiwa, semuenzaniso, pakuita basa rakasimba nevhidhiyo. MunaEpril kambani pre-kugadzirwa vhezheni yegumi nematanhatu TB hard drive ine HAMR tekinoroji; kuendeswa kwemasampuli emadhiraivha akadaro kwakatanga mukupera kwaKurume, asi ivo havazoendi mukugadzira. Mugore, sekureva kwevamiriri veSeagate, gumi nematanhatu TB modhi ichave iyo kambani masosi emari muchikamu cheseva. Serial vhezheni dzezvigadzirwa zveiyi vhoriyamu inosanganisa "perpendicular" kurekodha neTDMR pamahwendefa mapfumbamwe; Seagate inochinja kune "tiled" kurekodha chete kana ichigadzira gumi nemasere madhiraivha eTB, asi ivo vanozoita pasina matipi seHAMR.
Mugore rekarenda ra2020, Seagate ichaunza makumi maviri eTB madhiraivha ane HAMR tekinoroji. Nekufamba kwenguva, ichaita kuti zvikwanise kugadzira madhiraivha ane huwandu hunopfuura makumi mana TB, asi vese vakwikwidzi veSeagate vanovimbisa chinhu chimwe chete, vachishandisa tekinoroji yakati siyanei, saka kurwira mumusika wekutyaira kunovimbisa kuve kwakakomba. .
