Ndi kuchokera ku IHS Markit, makina osungira osakanizidwa (HDS) ozikidwa pa HDD ndi SSD ayamba kusowa chaka chino. Timakambirana mmene zinthu zilili panopa.

Mu 2018, ma flash arrays adapanga 29% ya msika wosungirako. Kwa njira zosakanizidwa - 38%. IHS Markit ali ndi chidaliro kuti ma SSD azitsogolera chaka chino. Malinga ndi kuyerekezera kwawo, ndalama zomwe amapeza kuchokera ku malonda amtundu wa flash zidzakwera kufika 33%, ndipo kuchokera ku hybrid arrays zidzatsika mpaka 30%.
Akatswiri amati kufunikira kochepa kwa makina osakanizidwa ndi msika womwe ukucheperachepera wa HDD. IDC ikuyembekeza kuti pofika chaka cha 2021 chiwerengero cha ma HDD opangidwa chidzatsikira ku zipangizo 284 miliyoni, zomwe ndi 140 miliyoni zosakwana zaka zitatu zapitazo. Kuchuluka kwa msika panthawi yomweyi kudzatsika ndi $ 750 miliyoni. Statista Izi, molingana ndi gwero lowunikira, kuyambira 2014, kuchuluka kwa ma HDD opangidwa kwatsika ndi zida za 40 miliyoni.
Malonda a HDD akugweranso mu gawo la data center. Malinga ndi lipoti lazachuma la Western Digital (WD), mchaka chathachi kuchuluka kwa ma HDD ogulitsidwa ku malo opangira ma data adatsika kuchokera pazida 7,6 miliyoni kufika pa 5,6 miliyoni (). Chaka chatha WD ngakhale kuti amakakamizika kutseka fakitale yawo ku Malaysia. Komanso chilimwe chatha, magawo a Seagate adatsika ndi 7%.
Chifukwa chiyani kufunikira kwa SSD kukukula?
Kuchuluka kwa deta yokonzedwa kukuwonjezeka. IDC imanena kuti kuchuluka kwa deta komwe kumapangidwa padziko lapansi kukula ndi 61% pachaka - pofika 2025 idzafika pamtengo wa 175 zettabytes. Zikuyembekezeka kuti theka la deta iyi lidzasinthidwa ndi malo opangira deta. Kuti athane ndi katunduyo, adzafunika makina osungira opangidwa ndi SSD apamwamba kwambiri. Pali zochitika zodziwika pamene kusintha kwa "solid state" kutsitsa zambiri kuchokera pankhokwe kasanu.
Makampani a IT akupanganso matekinoloje atsopano opangidwa kuti apititse patsogolo magwiridwe antchito a makina onse osungira. Mwachitsanzo, protocol ya NVMe-oF (NVM Express over Fabrics). Zimakupatsani mwayi wolumikiza ma drive ku seva kudzera pa PCI Express (m'malo mwazolowera zochepa ΠΈ ). Protocol ilinso ndi malamulo angapo omwe amachepetsa kuchedwa potumiza uthenga pakati pa SSD. Njira zofananira zachitika kale pamsika.
Mtengo wa SSDs ukutsika. Kumayambiriro kwa 2018, mtengo wa gigabyte wa kukumbukira kwa SSD kuwirikiza kakhumi kuposa HDD. Komabe, pofika kumapeto kwa 2018 iye kawiri kapena katatu (kuyambira masenti 20-30 mpaka 10 pa gigabyte). Malinga ndi akatswiri, pofika kumapeto kwa 2019 idzakhala masenti asanu ndi atatu pa gigabyte. Posachedwapa, mitengo ya SSD ndi HDD idzakhala yofanana - izi ndizo kale mu 2021.
Chimodzi mwa zifukwa za kuchepa mofulumira kwa mitengo ya SSD ndi mpikisano pakati pa opanga omwe akuyesera kukopa makasitomala ndi mitengo yotsika. Makampani ena, monga Huawei, ali kale olimba boma amayendetsa pamtengo wa hard drive ndi mphamvu yomweyo.
Kugwiritsa ntchito mphamvu kukukula. Chaka chilichonse, malo opangira data amagwiritsa ntchito ma 200 terawatt-maola amagetsi. Wolemba , pofika 2030 chiwerengerochi chidzawonjezeka maulendo khumi ndi asanu. Ogwiritsa ntchito malo a data akuyesera kuwongolera magwiridwe antchito a makompyuta awo ndikuchepetsa kugwiritsa ntchito mphamvu.
Njira imodzi yochepetsera mtengo wamagetsi mu data center ndi kudzera pa hard-state drives. Mwachitsanzo, KIO Networks, kampani yomwe ikugwira ntchito mumtambo, SSD kuchuluka kwa magetsi ogwiritsidwa ntchito ndi data center ndi 60%. Nthawi yomweyo, ma hard drive ali ndi mphamvu zambiri kuposa ma hard drive. MU Asayansi aku Brazil ndi aku France mu 2018, ma SSD adapeza ma HDD potengera kuchuluka kwa data yomwe imasamutsidwa pa joule imodzi yamphamvu.

Nanga bwanji HDD?
Ndikochedwa kwambiri kulemba ma hard drive. Ogwiritsa ntchito malo a data apitiliza kuzigwiritsa ntchito posungirako zosungira zakale ndi zosunga zobwezeretsera kwa nthawi yayitali. Kuchokera mu 2016 mpaka 2021, kuchuluka kwa malonda a HDD kuti asunge zomwe sizimagwiritsidwa ntchito kawirikawiri. kawiri. Zomwe zikuchitika zitha kuwonekanso m'malipoti azachuma a Seagate wopanga ma hard drive: kuyambira 2013 mpaka 2018, kufunikira kwa zinthu zamakampani pazantchito "zozizira" kudakwera ndi 39% (8 slide). ).
Kusungirako kuzizira sikufuna kuchita bwino kwambiri, kotero palibe chifukwa chofotokozera magulu a SSD mwa iwo - makamaka pamene mtengo wa ma drive olimba (ngakhale ukuchepa) udakali wokwera. Pakalipano, ma HDD akugwiritsidwabe ntchito ndipo apitirizabe kugwiritsidwa ntchito mu data center.
