Los ntawm los ntawm IHS Markit, hybrid storage systems (HDS) raws li HDD thiab SSD yuav pib tsawg dua xyoo no. Peb tham txog qhov xwm txheej tam sim no.

Hauv 2018, flash arrays suav txog 29% ntawm kev lag luam cia. Rau kev daws teeb meem hybrid - 38%. IHS Markit ntseeg siab tias SSDs yuav ua tus thawj coj xyoo no. Raws li lawv cov kev kwv yees, cov nyiaj tau los ntawm kev muag khoom ntawm flash arrays yuav nce mus rau 33%, thiab los ntawm hybrid arrays yuav txo mus rau 30%.
Cov kws tshaj lij qhia txog qhov kev thov qis rau cov tshuab hybrid rau kev lag luam HDD shrinking. IDC cia siab tias los ntawm 2021 tus naj npawb ntawm HDDs tsim yuav poob mus rau 284 lab cov khoom siv, uas yog 140 lab tsawg dua peb xyoos dhau los. Kev lag luam ntim nyob rau tib lub sijhawm yuav txo los ntawm $ 750 lab. Statista Cov qauv no, raws li kev txheeb xyuas cov peev txheej, txij li xyoo 2014, qhov ntim ntawm HDDs tsim tau poob los ntawm 40 lab cov khoom siv.
HDD muag kuj tseem poob rau hauv cov ntaub ntawv chaw ntu ntu. Raws li daim ntawv tshaj tawm nyiaj txiag ntawm Western Digital (WD), xyoo dhau los, tus naj npawb ntawm HDDs muag rau cov chaw khaws ntaub ntawv poob los ntawm 7,6 lab cov khoom siv rau 5,6 lab (). Xyoo tas los WD txawm tias lawv raug yuam kaw lawv lub Hoobkas hauv Malaysia. Tsis tas li ntawd lub caij ntuj sov dhau los, Seagate shares poob los ntawm 7%.
Vim li cas qhov kev thov rau SSD loj hlob?
Lub ntim ntawm cov ntaub ntawv ua tiav yog nce. IDC hais tias tus nqi ntawm cov ntaub ntawv tsim tawm hauv ntiaj teb loj hlob los ntawm 61% txhua xyoo - los ntawm 2025 nws yuav ncav cuag tus nqi ntawm 175 zettabytes. Nws cia siab tias ib nrab ntawm cov ntaub ntawv no yuav ua tiav los ntawm cov chaw khaws ntaub ntawv. Txhawm rau tiv thaiv cov khoom thauj, lawv yuav xav tau kev ua haujlwm siab SSD-raws li kev cia khoom. Muaj cov xwm txheej paub thaum hloov mus rau "lub xeev khov" rub tawm cov ntaub ntawv los ntawm database rau lub sij hawm.
Cov tuam txhab IT tseem tab tom tsim cov thev naus laus zis tshiab tsim los ua kom muaj kev ua tau zoo ntawm txhua lub flash cia. Piv txwv li, NVMe-oF (NVM Express over Fabrics) raws tu qauv. Nws tso cai rau koj los txuas cov drives rau cov neeg rau zaub mov ntawm PCI Express (es tsis txhob muaj kev cuam tshuam tsawg dua ΠΈ ). Cov txheej txheem kuj tseem muaj cov lus txib uas txo qhov ncua sij hawm thaum hloov cov ntaub ntawv ntawm SSDs. Cov kev daws teeb meem zoo sib xws twb muaj lawm ntawm kev ua lag luam.
Tus nqi ntawm SSDs poob. Thaum pib ntawm 2018, tus nqi ntawm ib gigabyte ntawm SSD nco kaum npaug siab dua HDD. Txawm li cas los xij, thaum kawg ntawm 2018 nws ob mus rau peb zaug (los ntawm 20-30 mus rau 10 xees ib gigabyte). Raws li cov kws tshaj lij, thaum kawg ntawm 2019 nws yuav yog yim xees ib gigabyte. Nyob rau yav tom ntej, tus nqi rau SSD thiab HDD yuav sib npaug - qhov no yog xa 2021.
Ib qho ntawm cov laj thawj rau kev poob qis hauv SSD cov nqi yog kev sib tw ntawm cov tuam txhab uas tab tom sim nyiam cov neeg siv khoom nrog tus nqi qis. Qee lub tuam txhab, xws li Huawei, twb yog lawm solid state drives ntawm tus nqi ntawm hard drives nrog tib lub peev xwm.
Kev siv hluav taws xob loj zuj zus. Txhua xyoo, cov chaw khaws ntaub ntawv siv 200 terawatt-teev hluav taws xob. Los ntawm , los ntawm 2030 daim duab no yuav nce kaum tsib zaug. Cov neeg khiav dej num hauv chaw zov me nyuam tab tom sim txhim kho kev ua tau zoo ntawm lawv cov kev siv computer thiab txo kev siv hluav taws xob.
Ib txoj hauv kev los txo cov nqi hluav taws xob hauv cov ntaub ntawv chaw yog los ntawm cov khoom siv hauv xeev. Piv txwv li, KIO Networks, lub tuam txhab ua haujlwm hauv huab, SSD tus nqi hluav taws xob siv los ntawm cov chaw khaws ntaub ntawv los ntawm 60%. Nyob rau tib lub sij hawm, solid-state drives muaj zog efficiency dua hard drives. IN Cov kws tshawb fawb Brazilian thiab Fab Kis xyoo 2018, SSDs tau dhau HDDs raws li tus nqi ntawm cov ntaub ntawv xa mus rau ib joule ntawm lub zog.

Yuav ua li cas yog HDD?
Nws tseem ntxov dhau los sau tawm cov hard drive. Cov neeg khiav dej num hauv chaw zov me nyuam yuav txuas ntxiv siv lawv rau kev cia txias ntawm cov ntaub ntawv khaws tseg thiab khaws cia ntev ntev. Los ntawm 2016 txog 2021, muag ntim ntawm HDDs khaws cia tsis tshua siv cov ntaub ntawv ua ob npaug. Cov qauv no tseem tuaj yeem pom hauv daim ntawv tshaj tawm nyiaj txiag ntawm lub chaw tsim khoom hard drive Seagate: los ntawm 2013 txog 2018, qhov kev thov rau lub tuam txhab cov khoom lag luam rau cov haujlwm "txias" nce 39% (8 swb. ).
Kev cia txias tsis tas yuav tsum muaj kev ua haujlwm siab, yog li tsis muaj qhov taw qhia hauv kev qhia SSD arrays rau hauv lawv - tshwj xeeb tshaj yog thaum tus nqi ntawm cov khoom siv hauv xeev (txawm tias txo qis) tseem siab. Txog tam sim no, HDDs tseem siv tau thiab yuav txuas ntxiv siv rau hauv cov ntaub ntawv chaw.
