Ngu ukusuka kwi-IHS Markit, iinkqubo zokugcina ezixubileyo (i-HDS) ezisekelwe kwi-HDD kunye ne-SSD ziya kuqala ukuba zifunwa ngaphantsi kulo nyaka. Sixoxa ngemeko yangoku.

Kwi-2018, i-flash arrays ibalwa kwi-29% yemarike yokugcina. Kwizisombululo ze-hybrid - 38%. I-IHS Markit iqinisekile ukuba ii-SSD ziya kukhokela kulo nyaka. Ngokutsho koqikelelo lwabo, ingeniso evela kwiintengiso ze-flash arrays iya kunyuka ukuya kwi-33%, kwaye ukusuka kwi-hybrid arrays iya kuncipha ukuya kuma-30%.
Iingcali zibalela imfuno ephantsi yeenkqubo zemixube kwimakethi ecuthekayo yeHDD. I-IDC ilindele ukuba ngo-2021 inani le-HDDs eziveliswayo liya kuhla ukuya kwi-284 yezigidi zezixhobo, ezizigidi ezili-140 ngaphantsi kweminyaka emithathu edlulileyo. Umthamo wemarike ngexesha elifanayo uya kuncipha nge-$ 750 yezigidi. Statista Lo mkhwa, ngokutsho kwesixhobo sokuhlalutya, ukususela ngo-2014, umthamo wee-HDD eziveliswayo uye wehla nge-40 yezigidi zezixhobo.
Iintengiso ze-HDD nazo ziwela kwicandelo ledatha yedatha. Ngokwengxelo yezemali ye-Western Digital (WD), kunyaka odlulileyo inani le-HDD ezithengiswa kumaziko edatha lehla ukusuka kwi-7,6 yezigidi zezixhobo ukuya kwi-5,6 yezigidi (). Kunyaka ophelileyo WD nkqu ukuba banyanzeleke ukuba bavale umzi-mveliso wabo eMalaysia. Kwakhona ehlotyeni elidlulileyo, izabelo zeSeagate zehle nge-7%.
Kutheni imfuno ye-SSD ikhula?
Umthamo wedatha esetyenzisiweyo uyanda. I-IDC ithi inani ledatha eveliswe kwihlabathi ukukhula ngo-61% ngonyaka - ngo-2025 kuya kufikelela kwixabiso le-175 zettabytes. Kulindeleke ukuba isiqingatha sale datha sisetyenzwe ngamaziko edatha. Ukujamelana nomthwalo, baya kufuna iisistim zokugcina ezisekelwe kwi-SSD. Kukho iimeko ezaziwayo xa utshintsho oluya “kwimeko eqinileyo” ukukhuphela ulwazi kwisiseko sedatha amaxesha amathandathu.
Iinkampani ze-IT zikwaphuhlisa itekhnoloji entsha eyenzelwe ukunyusa ngakumbi ukusebenza kweenkqubo zokugcinwa kweflash. Umzekelo, iprotocol yeNVMe-oF (NVM Express over Fabrics). Ikuvumela ukuba uqhagamshele iidrive kumncedisi ngePCI Express (endaweni yojongano olunemveliso enganeno и ). Iprotocol nayo iqulethe isethi yemiyalelo enciphisa ukulibaziseka xa uhambisa ulwazi phakathi kwe-SSD. Izisombululo ezifanayo sele zikhona kwintengiso.
Iindleko zee-SSD ziyehla. Ekuqaleni kwe-2018, ixabiso le-gigabyte yememori ye-SSD ngokuphindwe kashumi ngaphezulu kweHDD. Nangona kunjalo, ekupheleni kuka-2018 yena amaxesha amabini ukuya kwamathathu (ukusuka kwi-20-30 ukuya kwi-10 yeesenti kwi-gigabyte). Ngokutsho kweengcali, ekupheleni kwe-2019 iya kuba neesenti ezisibhozo ngegigabyte. Kwixesha elizayo elingekude, amaxabiso e-SSD kunye ne-HDD aya kulingana - oku sele ku 2021.
Esinye sezizathu zokuhla ngokukhawuleza kwamaxabiso e-SSD kukukhuphisana phakathi kwabavelisi abazama ukutsala abathengi ngamaxabiso aphantsi. Ezinye iinkampani, ezinje ngeHuawei, sele zikhona imeko eqinileyo drives ngexabiso hard drives kunye umthamo ofanayo.
Ukusetyenziswa kwamandla kuyakhula. Rhoqo ngonyaka, amaziko edatha asebenzisa iiyure ezingama-200 zeterawatt zombane. Ngu , ngowama-2030 eli nani liza kunyuka izihlandlo ezilishumi elinesihlanu. Abaqhubi beziko ledatha bazama ukuphucula ukusebenza kakuhle kweziseko zabo zekhompyutha kunye nokunciphisa ukusetyenziswa kwamandla.
Enye indlela yokunciphisa iindleko zombane kwiziko ledatha ngokusebenzisa i-slid-state drives. Umzekelo, i-KIO Networks, inkampani esebenza efini, i-SSD ubungakanani bombane osetyenziswe liziko ledatha nge-60%. Kwangaxeshanye, iidrive ze-slid-state zinamandla aphezulu aphezulu kunee-hard drives. IN Izazinzulu zaseBrazil kunye nesiFrentshi kwi-2018, ii-SSD zigqithise ii-HDD ngokwemali yedatha edluliselwe kwi-joule yamandla.

Kuthekani ngeHDD?
Kukwangoko ukuba ubhale ii-hard drives. Abaqhubi beziko ledatha baya kuqhubeka bezisebenzisa ukugcinwa okubandayo kogcino kunye nee-backups ixesha elide. Ukusukela ngo-2016 ukuya ku-2021, umthamo wokuthengisa wee-HDD zokugcina idatha engafane isetyenziswe. iphindwe kabini. Umkhwa unokubonwa nakwiingxelo zemali zomenzi we-hard drive Seagate: ukusuka kwi-2013 ukuya kwi-2018, imfuno yeemveliso zenkampani yemisebenzi "ebandayo" yanda nge-39% (8 isilayidi. ).
Ukugcinwa okubandayo akufuni ukusebenza okuphezulu, ngoko akukho sizathu sokwazisa uluhlu lwe-SSD kubo - ngakumbi ngelixa ixabiso le-solid-state drives (nangona liyancipha) lihlala liphezulu. Okwangoku, ii-HDD zihlala zisetyenziswa kwaye ziya kuqhubeka zisetyenziswa kwiziko ledatha.
