Kulo nyaka, kulandela iToshiba, iWDC kunye neSeagate yaqala ukuvelisa iidrive ezinzima ezineepleyiti zemagneti ezisi-9. Oku kwaba ngumbulelo onokwenzeka ekufikeni kwamacwecwe amabini amancinci kunye nokutshintshela kwiibhloko ezivaliweyo kunye namacwecwe apho umoya utshintshwa yi-helium. Uxinaniso olusezantsi lwe-helium lubeka umthwalo oncitshisiweyo kwiipleyiti kwaye lukhokelela ekusetyenzisweni okuphantsi kombane ngeenjini zokujikeleza. Ngaloo ndlela, umthamo we-HDD drives uthathe elinye inyathelo ukuya phambili - ukuya kwi-16-18 TB kwimeko yokurekhoda kwe-perpendicular eqhelekileyo kunye ne-18-20 TB xa usebenzisa "i-tile" yokurekhoda kohlobo lwe-SMR. Kwaye ke izimvo zahlulwa...
Ngokutsho kwe-Western Digital, inkampani iya kuqhubeka nokunyusa umthamo we-hard drives ngokutshintshela kwiipleyiti ezinokurekhoda okuncediswa yi-microwave (i-MAMR), kunye ne-Seagate ngokulungelelanisa itekhnoloji ukuxhasa ukufudumeza kwendawo yokurekhodwa kwamagnetic (HAMR). Ikhutshwe ngenkxaso ye-MAMR . Mhlawumbi ukhona okanye akakho. Kwaye uqhuba nge-HAMR ukukhutshwa ngobuninzi kwisiqingatha sokuqala sika-2020 ngendlela eqhelekileyo ye-18 TB HDDs kunye ne-20 TB ene-SMR. Kodwa kukho uluvo lwesithathu. Ilele kwinto yokuba ii-hard drives kunye ne-MAMR kunye ne-HAMR kude kube ngu-2022, kwaye njengenye indlela, ngo-2021 ii-HDD ezine-10 eziqhelekileyo ze-magnetic platters ziya kubonakala ngobuninzi.
Ngokutsho kwabahlalutyi be-Trendfocus, i-WDC kunye ne-Seagate basebenza ekudaleni i-10-platter hard drives. Iingcali zibiza ukulungelelaniswa okucothayo kwee-drives ngeteknoloji ye-SMR kwi-niche ebizwa ngokuba yi-nearline-HDD imfuneko yokuvela kwezixhobo ezinjalo. Iidrive zehard drive zeklasi ezikufuphi zinemeko yesithintelo phakathi kogcino olucothayo lwedisk kunye ne-RAM (okanye, ngenye indlela, phakathi koluhlu lwe-caching kunye nokugcinwa kwedisk). Itekhnoloji ye-SMR ifuna ixesha lokurekhoda idatha kuba ibandakanya ukugqithelana ngokuyinxenye kweengoma. Abakhi boluhlu lwediski bayathandabuza ukuthatha iimodeli ze-SMR kwaye bayakwamkela ngovuyo ii-HDD eziqhelekileyo ezinomthamo omkhulu.
Ngokutsho kweTrendfocus, imfuno ephantsi yeemodeli ze-SMR kunye neetekhnoloji ezikrwada ze-MAMR/HAMR ziya kunyanzela abavelisi ukuba bagxile kwimveliso yee-HDDs ngokurekhoda okuqhelekileyo. Ngamanye amazwi, ukusukela ekuqaleni kuka-2020, ii-HDD ezili-18 ze-TB ezirekhodiweyo kunye neepleyiti ezisi-9 ziya kuveliswa ngobunzima bokutshintsha ukuya kwi-20 TB HDDs nge-SMR ukuya ekupheleni kuka-2020, kwaye ukusuka ngo-2021 20 TB HDDs ezineepleyiti ezili-10 ziya kuqala kukhutshwa, kulandele ukukhutshwa ngo-2022 kwee-HDD ezinamandla ngakumbi ngetekhnoloji ye-MAMR/HAMR ngaphandle kwe-SMR.
