Xyoo no, tom qab Toshiba, WDC thiab Seagate tau pib tsim cov hard drive nrog 9 magnetic platters. Qhov no tau dhau los ua tsaug rau qhov tshwm sim ntawm ob daim hlau nyias thiab kev hloov pauv mus rau cov ntawv ntim nrog cov phaj uas cua hloov los ntawm helium. Qhov qis dua ntawm Helium qhov chaw txo qis ntawm cov paib thiab ua rau kev siv hluav taws xob tsawg los ntawm kev sib hloov tig kev sib hloov hloov cov motors. Yog li, lub peev xwm ntawm HDDR tau coj lwm kauj ruam tom ntej - txog li txog 16-18 tB thaum siv "tiled" sau ntawm SMR Hom. Thiab ces kev xav tau muab faib ...
Raws li Western Digital, lub tuam txhab yuav txuas ntxiv ua kom muaj peev xwm ntawm cov tsav nyuaj los ntawm kev hloov mus rau platters nrog microwave-pab kaw lus (MAMR), thiab Seagate los ntawm kev hloov kho thev naus laus zis los txhawb cov cua sov hauv zos ntawm cov ntaub ntawv sib nqus (HAMR). Tso tawm nrog MAMR kev txhawb nqa . Nws muaj los yog nws tsis muaj. Thiab cov tsav nrog Hamr rau kev tso tawm loj hauv thawj ib nrab xyoo 2020 hauv daim ntawv ntawm 18 TB HDDs thiab 20 TB nrog SMR. Tab sis muaj peb lub tswv yim. Nws nyob hauv qhov tseeb tias hard drives nrog MAMR thiab HAMR kom txog rau thaum 2022, thiab raws li lwm txoj hauv kev, hauv 2021 HDDs nrog 10 cov pa sib nqus platters yuav tshwm sim.
Raws li cov kws tshuaj ntsuam Trendfocus, WDC thiab Seagate tab tom ua haujlwm tsim 10-platter hard drives. Cov kws tshaj lij hu qhov kev hloov pauv qeeb ntawm cov tsav tsheb nrog SMR thev naus laus zis hauv niche ntawm qhov hu ua ze-HDD qhov yuav tsum tau ua ua ntej rau qhov tshwm sim ntawm cov khoom siv no. Nyob ze cov chav kawm hard drives yog conditionally tsis nyob nruab nrab ntawm qeeb disk cia thiab RAM (los yog, hloov, ntawm caching arrays thiab disk cia). SMR thev naus laus zis xav tau sijhawm los sau cov ntaub ntawv vim tias nws cuam tshuam ib feem ntawm kev sib tshooj. Cov neeg tsim khoom ntawm disk arrays tsis kam coj SMR qauv thiab zoo siab txais tos cov HDDs nrog lub peev xwm loj dua.
Raws li TrressFocus, tsis tshua xav tau rau SMR qauv thiab cov kws ua haujlwm hnyav yuav yuam cov tuam txhab kom tsom rau kev tsim cov HDD nrog cov ntaub ntawv sib xyaw. Hauv lwm lo lus, txij thaum pib ntawm 2020, 18 tus lej TB nrog SMR txog 9, thiab los ntawm 20 2020 tus lej TBDs nrog 2021 platters yuav pib Tso tawm, ua raws li kev tso tawm hauv 20 ntawm ntau cov HD capacious HDDs nrog Mamr / Hamr Technologies tsis muaj SMR / Hamr Technologies tsis muaj SMR.
