WDC ndi Seagate akuganiza zotulutsa ma hard drive a 10-platter

Chaka chino, kutsatira Toshiba, WDC ndi Seagate adayamba kupanga ma hard drive okhala ndi 9 maginito mbale. Izi zinakhala zotheka chifukwa cha kubwera kwa mbale zoonda komanso kusintha kwa midadada yotsekedwa ndi mbale zomwe mpweya umasinthidwa ndi helium. Kachulukidwe kakang'ono ka helium kumayika katundu wocheperako pama mbale ndipo kumapangitsa kuti magetsi azitsika ndi ma spindle rotation motors. Chifukwa chake, kuchuluka kwa ma drive a HDD kwapitanso patsogolo - mpaka 16-18 TB pankhani yojambulira wamba komanso mpaka 18-20 TB mukamagwiritsa ntchito kujambula kwamtundu wa SMR. Ndiyeno maganizo anagawanika...

Malinga ndi Western Digital, kampaniyo ipitiliza kukulitsa kuchuluka kwa ma hard drive posinthira ku mbale zojambulira zothandizidwa ndi ma microwave (MAMR), ndi Seagate posintha ukadaulo kuti zithandizire kutentha kwanthawi zonse kwa maginito kujambula (HAMR). Yotulutsidwa ndi thandizo la MAMR wosakhazikika. Mwina alipo kapena kulibe. Ndipo amayendetsa ndi HAMR analonjeza kuti amasulidwe ambiri mu theka loyamba la 2020 mu mawonekedwe a 18 TB HDDs ndi 20 TB okhala ndi SMR. Koma pali lingaliro lachitatu. Zili mu mfundo yakuti hard drive ndi MAMR ndi HAMR akhoza kuchedwa mpaka 2022, ndipo ngati njira ina, mu 2021 ma HDD okhala ndi ma 10 ochiritsira maginito mbale adzawoneka ambiri.

Malinga ndi akatswiri a Trendfocus, WDC ndi Seagate akugwira ntchito yopanga ma hard drive a 10-platter hard. Akatswiri amatcha kusinthasintha kwapang'onopang'ono kwa ma drive ndi ukadaulo wa SMR mu kagawo kakang'ono kazomwe zimatchedwa pafupi-HDD ndikofunikira kuti zida zotere ziwonekere. Ma hard drive amtundu wa Nearline ali ndi malire pakati pa kusungirako pang'onopang'ono kwa disk ndi RAM (kapena, m'malo mwake, pakati pa ma caching arrays ndi disk yosungirako). Ukadaulo wa SMR umafunika nthawi kuti ulembe zambiri chifukwa umaphatikizana pang'ono ndi nyimbo. Opanga ma disk arrays safuna kutenga mitundu ya SMR ndipo angalandire mosangalala ma HDD okhazikika okhala ndi mphamvu zazikulu.

Malinga ndi Trendfocus, kufunikira kochepera kwa mitundu ya SMR ndi matekinoloje a MAMR/HAMR osakanizika kukakamiza opanga kuti aziyang'ana kwambiri kupanga ma HDD ndi kujambula wamba. Mwanjira ina, kuyambira koyambirira kwa 2020, ma HDD 18 a TB okhala ndi zojambulira za perpendicular ndi mbale 9 zidzapangidwa mochuluka ndikusintha kupita ku 20 TB HDDs ndi SMR chakumapeto kwa 2020, ndipo kuyambira 2021 20 TB HDDs yokhala ndi mbale 10 iyamba. kumasulidwa, kutsatiridwa ndikutulutsidwa mu 2022 kwa ma HDD ochulukirapo okhala ndi matekinoloje a MAMR/HAMR opanda SMR.
