Ngu kusuka ku-IHS Markit, izinhlelo ze-hybrid storage (HDS) ezisekelwe ku-HDD ne-SSD zizoqala ukudingeka kancane kulo nyaka. Sixoxa ngesimo samanje.

Ngo-2018, ama-flash arrays abalelwa ku-29% wemakethe yokugcina. Ngezixazululo ze-hybrid - 38%. I-IHS Markit iyaqiniseka ukuthi ama-SSD azohola kulo nyaka. Ngokwezilinganiso zabo, imali engenayo evela ekuthengisweni kwama-flash arrays izokhuphuka ifike ku-33%, futhi isuka kuma-hybrid arrays izokwehla iye ku-30%.
Ochwepheshe bathi isidingo esiphansi sezinhlelo ze-hybrid emakethe ye-HDD enciphayo. I-IDC ilindele ukuthi ngo-2021 isibalo sama-HDD akhiqizwayo sizokwehla siye emishinini eyizigidi ezingama-284, okusho ukuthi ngezigidi eziyi-140 ngaphansi kweminyaka emithathu edlule. Umthamo wemakethe ngesikhathi esifanayo uzokwehla ngezigidi ezingu-750 zamaRandi. Statista Lo mkhuba, ngokusho kwensiza yokuhlaziya, kusukela ngo-2014, umthamo wama-HDD akhiqizwayo wehle ngamadivayisi ayizigidi ezingu-40.
Ukuthengiswa kwe-HDD nakho kuyawa engxenyeni yesikhungo sedatha. Ngokombiko wezezimali we-Western Digital (WD), ngonyaka odlule inani lama-HDD athengiselwe izikhungo zedatha lehle lisuka kumadivayisi ayizigidi ezingu-7,6 laya ezigidini ezingu-5,6 (). Ngonyaka odlule WD ngisho ukuthi baphoqeleke ukuthi bavale imboni yabo eMalaysia. Futhi ehlobo eledlule, amasheya e-Seagate ehle ngo-7%.
Kungani isidingo se-SSD sikhula?
Ivolumu yedatha ecutshunguliwe iyakhula. I-IDC ithi inani ledatha ekhiqizwa emhlabeni ikhule ngo-61% ngonyaka - ngo-2025 izofinyelela inani lama-zettabytes angu-175. Kulindeleke ukuthi ingxenye yale datha izocutshungulwa izikhungo zedatha. Ukuze babhekane nomthwalo, bazodinga amasistimu okugcina asekelwe ku-SSD asebenza kahle kakhulu. Kunezimo ezaziwayo lapho ukushintshela “kusimo esiqinile” ukulanda ulwazi kusizindalwazi izikhathi eziyisithupha.
Izinkampani ze-IT futhi zakha ubuchwepheshe obusha obuklanyelwe ukukhulisa ukusebenza kwezinhlelo zokugcinwa kwe-flash. Isibonelo, iphrothokholi ye-NVMe-oF (NVM Express over Fabrics). Ikuvumela ukuthi uxhume amadrayivu kuseva nge-PCI Express (esikhundleni sezindawo ezikhiqiza kancane и ). Iphrothokholi futhi iqukethe isethi yemiyalo enciphisa ukubambezeleka lapho kudluliswa ulwazi phakathi kwama-SSD. Izixazululo ezifanayo sezivele zikhona emakethe.
Izindleko zama-SSD ziyehla. Ekuqaleni kuka-2018, intengo ye-gigabyte yememori ye-SSD ukuphakama okuphindwe kashumi kune-HDD. Nokho, ekupheleni kuka-2018 yena izikhathi ezimbili kuya kwezintathu (kusuka ku-20-30 kuya ku-10 cents per gigabyte). Ngokusho kochwepheshe, ekupheleni kuka-2019 izoba ngamasenti ayisishiyagalombili ngegigabhayithi. Esikhathini esizayo esiseduze, amanani e-SSD ne-HDD azolingana - lokhu kuyalingana kakade ngo-2021.
Esinye sezizathu zokwehla ngokushesha kwamanani e-SSD ukuncintisana phakathi kwabakhiqizi abazama ukuheha amakhasimende ngamanani aphansi. Ezinye izinkampani, ezifana neHuawei, sezivele zikhona amadrayivu wesimo esiqinile ngentengo yama-hard drive anomthamo ofanayo.
Ukusetshenziswa kwamandla kuyakhula. Njalo ngonyaka, izikhungo zedatha zisebenzisa amahora angu-200 we-terawatt kagesi. Ngu , ngo-2030 lesi sibalo sizokhuphuka izikhathi eziyishumi nanhlanu. Abaqhubi besikhungo sedatha bazama ukuthuthukisa ukusebenza kahle kwengqalasizinda yabo yekhompyutha nokunciphisa ukusetshenziswa kwamandla.
Enye indlela yokunciphisa izindleko zikagesi esikhungweni sedatha ngokusebenzisa amadrayivu e-solid-state. Isibonelo, i-KIO Networks, inkampani esebenza efwini, i-SSD inani likagesi elidliwe yisikhungo sedatha ngo-60%. Ngasikhathi sinye, amadrayivu e-solid-state asebenza kahle kakhulu kunama-hard drive. IN Ososayensi baseBrazil nabaseFrance ngo-2018, ama-SSD adlula ama-HDD ngokwenani ledatha edluliswa ngejoule ngayinye yamandla.

Kuthiwani nge-HDD?
Kusekuseni kakhulu ukubhala ama-hard drive. Abaqhubi besikhungo sedatha bazoqhubeka nokuzisebenzisa ukugcina okubandayo kwezingobo zomlando kanye nezipele isikhathi eside. Kusukela ngo-2016 kuya ku-2021, umthamo wokuthengisa wama-HDD wokugcina idatha engavamile ukusetshenziswa kabili. Umkhuba ungabonakala futhi emibikweni yezezimali yomkhiqizi we-hard drive i-Seagate: kusukela ngo-2013 kuya ku-2018, isidingo semikhiqizo yenkampani yemisebenzi "ebandayo" senyuke ngo-39% (8 slide ).
Isitoreji esibandayo asidingi ukusebenza okuphezulu, ngakho-ke asikho isidingo sokwethula ama-SSD afanayo kuwo - ikakhulukazi ngenkathi intengo yamadrayivu e-solid-state (yize yehla) ihlala iphezulu. Okwamanje, ama-HDD asasebenza futhi azoqhubeka esetshenziswa esikhungweni sedatha.
