Kulo nyaka, kulandela u-Toshiba, i-WDC kanye ne-Seagate baqale ukukhiqiza ama-hard drive anamapuleti kazibuthe ayi-9. Lokhu kwaba ukubonga okungenzeka ngenxa yokufika kwawo womabili amapuleti azacile kanye nokushintshela kumabhlogo avaliwe anamapuleti lapho umoya ushintshwa khona i-helium. Ukuminyana okuphansi kwe-helium kubeka umthwalo oncishisiwe kumapuleti futhi kuholela ekwehliseni ukusetshenziswa kukagesi ngama-spindle rotation motors. Ngakho-ke, amandla okushayela kwe-HDD athathe elinye igxathu eliya phambili - afinyelela ku-16-18 TB esimweni sokurekhoda okujwayelekile kwe-perpendicular futhi kufika ku-18-20 TB lapho usebenzisa ukuqoshwa "okufakwe amathayela" kohlobo lwe-SMR. Kwabe sekuhlukaniswa imibono...
Ngokusho kwe-Western Digital, inkampani izoqhubeka nokukhulisa umthamo wama-hard drive ngokushintshela kumapuleti anokuqoshwa okusizwa yi-microwave (MAMR), kanye ne-Seagate ngokulungisa ubuchwepheshe ukuze busekele ukushisisa kwasendaweni kokuqoshwa kazibuthe (HAMR). Ikhishwe ngokusekelwa kwe-MAMR . Ukhona noma akekho. Futhi ushayela nge-HAMR ukuze kukhishwe ngobuningi engxenyeni yokuqala ka-2020 ngendlela evamile ye-TB HDD eyi-18 kanye ne-20 TB ene-SMR. Kodwa kunombono wesithathu. Kulele eqinisweni lokuthi ama-hard drive ane-MAMR ne-HAMR kuze kube ngu-2022, futhi njengenye indlela, ngo-2021 ama-HDD anamapuleti kazibuthe avamile ayi-10 azovela ngobuningi.
Ngokusho kwabahlaziyi be-Trendfocus, i-WDC ne-Seagate basebenzela ukwakha ama-hard drive angu-10-platter. Ochwepheshe babiza ukushintshwa kancane kokushayela ngobuchwepheshe be-SMR ku-niche yalokho okubizwa nge-nearline-HDD njengemfuneko yokuvela kwamadivayisi anjalo. Amadrayivu aqinile ekilasi eliseduze anesimo sebhafa phakathi kwesitoreji esinensayo sediski kanye ne-RAM (noma, okuhlukile, phakathi kweqoqo lesikhashana lokulondoloza kanye nokugcinwa kwediski). Ubuchwepheshe be-SMR budinga isikhathi ukuze urekhode idatha ngoba ihlanganisa ukugqagqana kwamathrekhi. Abakhi bamalungu afanayo ediski bayangabaza ukuthatha amamodeli e-SMR futhi bangawamukela ngenjabulo ama-HDD avamile anamakhono amakhulu.
Ngokusho kwe-Trendfocus, isidingo esiphansi samamodeli e-SMR kanye nobuchwepheshe obungahluziwe be-MAMR/HAMR kuzophoqa abakhiqizi ukuthi bagxile ekukhiqizweni kwama-HDD ngokuqoshwa okuvamile. Ngamanye amazwi, kusukela ekuqaleni kuka-2020, ama-HDD e-TB ayi-18 aqoshwa nge-perpendicular kanye namapuleti ayi-9 azokhiqizwa ngobuningi ngokuguqukela kuma-TB HDD angama-20 ane-SMR ngasekupheleni kuka-2020, futhi kusuka ku-2021 20 TB HDDs anepuleti eyi-10 azoqala akhishwe, kulandelwe ukukhishwa ngo-2022 kwama-HDD anamandla ngobuchwepheshe be-MAMR/HAMR ngaphandle kwe-SMR.
