By kubva kuIHS Markit, hybrid storage systems (HDS) yakavakirwa paHDD neSSD ichatanga kudiwa zvishoma gore rino. Tinokurukura mamiriro ezvinhu aripo.

Muna 2018, maflash arrays akaverengera 29% yemusika wekuchengetera. Kune mhinduro dzakasanganiswa - 38%. IHS Markit ine chivimbo chekuti SSDs ichatungamira gore rino. Zvinoenderana nefungidziro yavo, mari kubva mukutengesa kweflash arrays ichawedzera kusvika 33%, uye kubva kune yakasanganiswa arrays inoderera kusvika 30%.
Nyanzvi dzinoti kushomeka kwakaderera kwemahybrid masisitimu kumusika uri kuderera weHDD. IDC inotarisira kuti panosvika 2021 huwandu hwemaHDD anogadzirwa huchadzika kusvika pamamiriyoni mazana maviri nemakumi masere nemana emidziyo, inova mamirioni zana nemakumi mana pasi pemakore matatu apfuura. Huwandu hwemusika panguva imwe chete huchadzikira nemadhora mazana manomwe nemakumi mashanu emamiriyoni. Statista Aya maitiro, maererano neanalytical sosi, kubvira 2014, huwandu hweHDD dzakagadzirwa hwakaderera nemamiriyoni makumi mana emidziyo.
Kutengeswa kweHDD kuri kudonhawo muchikamu che data center. Zvinoenderana neshumo rezvemari reWestern Digital (WD), mugore rapfuura huwandu hweHDD dzakatengeswa kunzvimbo dzedata dzakadonha kubva pamamirioni manomwe nemazana matanhatu emidziyo kuenda ku7,6 miriyoni () Gore rakapera WD kunyange kuti vanomanikidzwa kuvhara fekitari yavo muMalaysia. Zvakare zhizha rapfuura, migove yeSeagate yakadonha ne7%.
Nei kudiwa kweSSD kuri kukura?
Huwandu hwe data yakagadziriswa huri kuwedzera. IDC inotaura kuti huwandu hwe data hunogadzirwa munyika kukura ne61% pagore - ne2025 ichasvika kukosha kwe175 zettabytes. Zvinotarisirwa kuti hafu ye data iyi ichagadziriswa ne data centers. Kuti vararame nemutoro, ivo vanozoda yakakwirira-inoshanda SSD-yakavakirwa kuchengetedza masisitimu. Pane zviitiko zvinozivikanwa apo shanduko ye "solid state" kudhawunirodha ruzivo kubva ku database katanhatu.
Makambani eIT ari kugadzirawo matekinoroji matsva akagadzirirwa kuwedzera mashandiro eese-flash kuchengetedza masisitimu. Semuenzaniso, iyo NVMe-oF (NVM Express pamusoro peFabrics) protocol. Iyo inokutendera kuti ubatanidze madhiraivha kune sevha kuburikidza nePCI Express (panzvimbo yezvishoma zvinogadzira interfaces ΠΈ ) Iyo protocol inewo seti yemirairo inoderedza kunonoka kana uchiendesa ruzivo pakati peSSD. Mhinduro dzakafanana dzatovepo pamusika.
Mutengo weSSD uri kudonha. Pakutanga kwe2018, mutengo wegigabyte yeSSD memory yakapetwa kagumi kupfuura HDD. Zvisinei, pakupera kwa2018 iye kaviri kusvika katatu (kubva pa20-30 kusvika ku10 cents per gigabyte). Maererano nenyanzvi, pakupera kwe2019 ichava masendi masere pagigabyte. Munguva pfupi iri kutevera, mitengo yeSSD neHDD ichave yakaenzana - izvi ndizvo kare muna 2021.
Chimwe chezvikonzero zvekudzikira nekukurumidza kwemitengo yeSSD kukwikwidza pakati pevagadziri vari kuyedza kukwezva vatengi nemitengo yakaderera. Mamwe makambani, akadai seHuawei, atove solid state inotyaira pamutengo wemadhiraivha ane simba rakafanana.
Kushandiswa kwesimba kuri kukura. Gore rega rega, nzvimbo dzedata dzinoshandisa mazana maviri eterawatt-maawa emagetsi. By , panosvika 2030 nhamba iyi ichawedzera kagumi neshanu. Data center operators vari kuedza kuvandudza kushanda kwekombiyuta yavo yehupfumi uye kuderedza kushandiswa kwesimba.
Imwe nzira yekudzikisa mutengo wemagetsi munzvimbo yedata iri kuburikidza neakasimba-state madhiraivha. Semuenzaniso, KIO Networks, kambani inoshanda mugore, SSD huwandu hwemagetsi anopedzwa nedata data ne60%. Panguva imwecheteyo, madhiraivha akasimba ane simba repamusoro pane dhiraivha yakaoma. IN Masayendisiti eBrazil neFrance muna 2018, maSSD akakunda HDD maererano nehuwandu hwe data inotamiswa pajoule yesimba.

Zvakadini neHDD?
Kwakasira kunyora ma hard drive. Vashandisi venzvimbo yedata vanozoenderera mberi nekuvashandisa kune inotonhora chengetedzo yezvinyorwa uye backups kwenguva yakareba. Kubva 2016 kusvika 2021, kutengesa vhoriyamu yeHDDs yekuchengetedza isingawanzo shandiswa data. zvakapetwa kaviri. Maitiro acho anogonawo kuoneka mumishumo yezvemari yeanogadzira hard drive Seagate: kubva 2013 kusvika 2018, kudiwa kwezvigadzirwa zvekambani zve "kutonhora" mabasa kwakawedzera ne39% (8 slide. ).
Kuchengetedza kutonhora hakudi kuita kwepamusoro, saka hapana chikonzero chekuunza SSD arrays mavari - kunyanya nepo mutengo wemadhiraivha ehurumende (kunyangwe uchidzikira) unoramba wakakwira. Parizvino, maHDD anoramba achishandiswa uye acharamba achishandiswa munzvimbo yedata.
