UFiliphu Novotny Uma ubukele ukwembulwa kwangoLwesibili kwama-iMac amasha, umhlathi wakho kungenzeka wehlile I-U.S. Amadeskithophu amasha e-All-in-one avela kwa-Apple azacile kakhulu, anamandla futhi anombukiso ongcono. IPhini likaMongameli Wezokumaketha uPhil Schiller naye wethule ngokuthanda okukhulu ubuchwepheshe obusha be-Fusion Drive, okufanele buhlanganise umthamo we-hard drive nesivinini se-SSD. Ingabe lena i-hybrid drive evamile, noma mhlawumbe ubuchwepheshe obusha sha?
Uma i-Apple isebenzise ngempela idrayivu eyi-hybrid njengoba siyazi namuhla, bekungeke kube yinto edabukisayo. Lawa madivayisi asebenza ngendlela yokuthi, ngaphezu kwe-hard disk yakudala enomthamo omkhulu, aqukethe nememori ye-flash (eyaziwa ngamadiski e-SSD). Lokhu kuvamise ukuba ngamagigabhayithi ambalwa ngosayizi kanye nokusebenza njengesigcinalwazi esinwetshiwe. I-hard drive ihlezi iphumula isikhathi esiningi futhi noqweqwe alujiki. Esikhundleni salokho, yonke idatha emisha ibhalwa kumemori ekhanyayo, evame ukushesha emisebenzini enjalo. Iphinde ifinyeze inqubo yokuqalisa ngokuqhathaniswa namadiski ajwayelekile. Inkinga ukuthi inzuzo yejubane iyanyamalala lapho ufunda amafayela amakhulu, futhi kunezinye izinkinga ezimbalwa ezicasulayo. Njengoba sekushiwo kakade, i-hard disk kumadivayisi anjalo ayisebenzi unomphela, futhi isidingo sokuyiqala ngokuvamile sisho ukwanda okuphawulekayo kwesikhathi sokufinyelela. Lapho ushintsha igiya, ama-disc nawo acekelwa phansi, ngokushesha okukhulu kunalapho ipuleti lilokhu lizungeza.
Ngakho-ke amadrayivu ayi-hybrid awabonakali njengekhandidethi elilungele ngokuphelele ukusetshenziswa ku-iMac entsha. Ngisho nekhasi elisemthethweni lamadeskithophu amasha kuwebhusayithi ye-Apple likhuluma ngokumelene nalobu buchwepheshe:
I-Fusion Drive ingumqondo ophumelelayo ohlanganisa umthamo omkhulu wamadrayivu aqinile endabuko nokusebenza okuphezulu kwememori ye-flash. Nge-Fusion Drive, i-iMac yakho iyashesha futhi isebenza kahle kakhulu ekwenzeni imisebenzi edinga idisk—kusuka ekuqaliseni kuye ekuqaliseni izinhlelo zokusebenza kuye ekungeniseni izithombe. Lokhu kungenxa yokuthi izinto ezisetshenziswa njalo zihlala zilungile kumemori esheshayo, kuyilapho ezisetshenziswa kancane zihlala ku-hard disk. Ukudluliselwa kwamafayela kwenzeka ngemuva, ngakho ngeke uze ukuqaphele.
Ngokolwazi esilufunde engqungqutheleni ngokwayo, i-Fusion Drive (ngemali eyengeziwe) izoqukatha i-hard drive engu-1 TB noma engu-3 TB kanye nememori engu-128 GB. Esethulweni sakhe, uPhil Schiller ubonise ukuthi uhlelo, izinhlelo zokusebenza namafayela asetshenziswa njalo kufanele abekwe elokuqala eliqanjwe igama, nalawo asetshenziswe kancane kowesibili. Lawa makhosombe amabili azohlanganiswa ngokuzenzakalelayo abe yivolumu eyodwa nge-software, futhi "ukuhlanganiswa" okunjalo kufanele kubangele ukufunda nokubhala ngokushesha.
Ngakho-ke, ngokususelwe kule mithombo emibili, singasho ngokuphepha ukuthi ukukhanya ku-iMac entsha akubonakali njengesandiso nje sememori ye-buffer. Ngokusho kwe-athikili yeseva Ars Technica lapha sinento ochwepheshe be-IT emkhakheni wezinkampani abakade beyisebenzisa isikhathi eside, okuyi-automatic tiering. Izinkampani ezinkulu zivame ukubhekana nenkinga ngenani elikhulu ledatha, okuyinto ngaphandle kokuphathwa okufanele kungabangela inkinga enkulu, ngokwejubane, ukucaca kanye nezindleko. Lezi zinkampani kufanele ziqale ukwakha ama-disk array futhi zivame ukusebenzisa umqondo wokugcinwa kwezingqimba eziningi: ukuze ugcine izindleko ziphansi ngangokunokwenzeka, lezi zinhlelo azisebenzisi kuphela ama-SSD asheshayo, kodwa futhi ama-hard disks ahamba kancane. Futhi ukuze usabalalise kabusha amafayela phakathi kwalezi zinhlobo ezimbili zokugcina, kusetshenziswa isendlalelo sedatha esizenzakalelayo.
Ake sicabange ukuthi omunye wabasebenzi benkampani ecatshangelwayo udala uhlaka lwesethulo futhi alugcine endaweni yokugcina okwabelwana ngayo ukuze angamlahleki. Ifayela liqale libekwe kusigcinalwazi esinensayo lapho lihlala lingenzi lutho izinsuku ezimbalwa lilindele ukuqedwa. Lapho uMnu. X wethu eqeda isethulo, usithumela kwabanye ozakwabo abambalwa ukuze sibuyekezwe. Baqala ukuyivula, ukwanda kwesidingo saleli fayela kubonakala ngesofthiwe ekhethekile, futhi ngaleyo ndlela ilihambisa ku-hard drive esheshayo kancane. Ake sithi lapho umphathi wenkampani enkulu ekhuluma ngephrezentheshini ngemva kwesonto emhlanganweni ovamile, wonke umuntu okhona uqala ukuyidawuniloda futhi ayithumele ngobuningi. Isistimu ibe isingenela futhi ngalesi sikhathi futhi ihambisa ifayela kudiski ye-SSD eshesha kakhulu. Ngale ndlela, singavele sicabange isimiso sokubeka idatha okuzenzakalelayo, ngisho noma empeleni asisebenzi ngawo wonke amafayela, kodwa ngamabhulokhi wedatha ezingeni lefayela elincane.
Ngakho-ke yile ndlela ukubekwa kwedatha okuzenzakalelayo kubukeka kanjani kuhlelo lwediski lochwepheshe, kodwa iFusion Drive efihliwe ekujuleni kwe-iMac entsha isebenza kanjani? Ngokusho kolwazi lwesayithi Anandtech inkumbulo yebhafa engu-4 GB iqala ukudalwa kumemori ye-flash, engaqhathaniswa nelingana namadrayivu ayi-hybrid. Ikhompyutha ibhala yonke idatha entsha kule buffer ize igcwale ngokuphelele. Ngaleso sikhathi, yonke eminye imininingwane igcinwa ku-hard drive. Isizathu salesi silinganiso ukuthi i-flash ishesha kakhulu ekusebenzeni kwamafayela amancane. Kodwa-ke, kulapho ukufana kwe-hybrid disc iphela khona.
Ngaphezu kwalokho, i-Fusion Drive isebenza njengoba sibonisile esibonelweni sezigaba ezimbili ezingenhla. Isofthiwe ekhethekile efihlwe ohlelweni lwe-Mountain Lion ibona ukuthi imaphi amafayela umsebenzisi awasebenzisa kakhulu futhi iwahambisa kumemori ye-flash engu-128 GB enamandla kakhulu. Ngakolunye uhlangothi, igcina idatha edingekayo kancane ku-hard disk. Ngesikhathi esifanayo, kubonakala sengathi i-Apple icabange ngokuphepha kwamafayela ahanjiswa ngale ndlela futhi ishiya inguqulo yokuqala kudiski yomthombo kuze kube yilapho umsebenzi usuqediwe. Ngakho-ke akufanele kube nezimanga ezingathandeki, isibonelo, ngemva kokunqamuka kwamandla okungalindelekile.
Ngokusekelwe kulolu lwazi, i-Fusion Drive ibukeka njengesici esisebenziseka kalula kuze kube manje, ikakhulukazi kubasebenzisi abavamile abangafuni ukubhekana nokuphatha amafayela kusitoreji esiningi esihlukene. Kumakhasimende afuna kakhulu, inkumbulo ye-flash enikeziwe engu-128 GB ingase inganeli kuyo yonke idatha yabo, kodwa ngakolunye uhlangothi, basengasebenzisa amadrayivu angaphandle asheshayo axhunyiwe, yithi, nge-Thunderbolt, kumafayela omsebenzi amakhulu.
Mhlawumbe into ebaluleke kakhulu ngalesi sikhathi ukwazi ukuthi lokhu kuzijabulisa kuzosibiza malini ngempela. Njengoba kubonakala kumanani entengo yemikhiqizo esanda kwethulwa, i-Apple ikhokhela inqubekelaphambili. Sizokhokha cishe imiqhele engu-35 yemodeli eyisisekelo ye-iMac ezitolo zesi-Czech, futhi ngisho nemodeli evamile evamile ayifaki i-Fusion Drive. Lokhu kudinga ukukhethwa njengokucushwa okukhethekile kwenkokhiso eyengeziwe ye-CZK 6. Ngakho-ke, akubandakanyiwe ukuthi kubasebenzisi abaningi izinzuzo ze-Fusion Drive ngeke zeqe inani layo eliyindida. Kodwa-ke, sizokwazi kuphela ukwenza ukuhlola okuhlosiwe lapho sizamela i-iMac entsha.
Ama-iMac amasha ahamba kancane kumenyu eyisisekelo kunochungechunge lwangaphambilini: anamadiski anesivinini esingu-5400 rpm. Ngakho-ke angikuqondi ukukhuphuka kwentengo kwamamodeli ayisisekelo. Uma kungenjalo, i-iMac entsha "encane kakhulu" ngokusobala inemiphetho, ekugcineni isahamba iye ekujuleni okufanele. I-Apple ibingasindisa le "innovation", ibizoba nesikhala esengeziwe ku-caseq futhi ibingashiya amadiski angama-3,5 ajwayelekile ane-7200 rpm lapho, futhi labo ababengafuni i-FD bekungeke kudingeke bahlupheke ngenxa yobuvila obucatshangelwe bentsha. iMacs. Kimina kubonakala sengathi i-Apple "ijahe amanzi", okungukuthi, kumadeskithophu.
Ezimweni eziningi, cishe awukwazi ngisho nokuthi, uhlelo nezinhlelo zakho ozithandayo zizolayishwa ku-SSD kanye neqiniso lokuthi amafayela akho azobe egijima ku-5400rpm esele, angicabangi ukuthi lokho kudlala indima enkulu kangaka. . Isikhathi kuphela engicabanga ukuthi kungaba inkinga kulapho uhambisa amafayela kwamanye amadivaysi angaphandle...
Nokho, lena inguqulo eyisisekelo. inodrayivu "5400rpm" kuphela futhi ngeke uze ukwazi ukwengeza i-fusion drive kuyo. engingaqondi ukuthi kungani. lokho kulungiselelwa kwanele kubantu abaningi futhi bafuna idiski esheshayo
Awukwazi ukuhlukanisa phakathi kuka-5400 no-7200. Lapha, ikhwalithi yediski ibaluleke kakhulu kunejubane lokujikeleza kwayo. Ungabona kuphela i-raptor ngo-10 rpm, futhi noma kunjalo cishe i-20%. Noma kunjalo, wonke umuntu osebenza kancane ngamakhompyutha ekugcineni uzothenga okungenani i-250GB SSD yohlelo. Lokho kubiza amarandi ambalwa namuhla.
Ngikholwe, angikuboni ngisho nokusebenza, ngineMacBook Pro engasusa kuyo idrayivu ngayishintsha ngediski ye-SSD, isivinini? Ayinakuqhathaniswa, futhi idrayivu yesibili yi-WD 500GB futhi "kuphela" 5400rpm, awukwazi ukusho. Uhlelo luyashesha, luqinile, luyashesha. Ngokwami, ngicabanga ukuthi konke kuzoncika kwikhwalithi yediski ye-SSD kune-HDD, futhi inani elikhulu lememori ye-RAM inokuthile okushoyo ngakho.
Kodwa yebo, kuyabonakala, akukho ngxabano ngalokho. Kodwa uma ujwayele ukusebenza ngedatha engu-200GB nangaphezulu, usuyazi kakade. Uma kunjalo, ngicabanga ukuthi isixazululo "esidala" se-SSD + HD 7200rpm singcono kune-FD enomkhawulo wesayizi nesivinini esinikezwa i-Apple. Kungakhathaliseki ukuthi kungenxa yemali eyengeziwe kuphela futhi isisekelo esine-disk engu-5400rpm siwubuthakathaka ngempela futhi sibiza kakhulu kunemodeli yangaphambilini.
Uxolo, kodwa angikaze ngisebenze ngefayela elingu-200GB...
amasampula, uyazi? ulokhu uthatha ezihlukene futhi ngeke zilingane ku-128GB, lapho kukhona ezinye izinto eziningi... Ngakho-ke noma kunjalo, umuntu uyobe esehliselwa kudiski engu-5400 eqalekisiweyo. Futhi lokho kuyalayisha kancane kakhulu. Yilokho okusebenzisayo lapho uvula iphrojekthi ku-Logic of Youth.
Ngicela ukwazi ukuthi yimaphi amasampuli owasebenzisayo kulo sayizi? Ngingathanda ngempela ukwazi. Ngiyabonga.
Ngakho-ke ingabe i-FD ingakhishwa ifakwe ku-iMac engumqansa?
Azikho izindaba ezengeziwe kimi.
Kungcono ukuba namadiski angu-2 kukhompyutha - i-SSD eyodwa ne-HDD eyodwa (lo mqondo ubuye ucabangele iqembu).
Kodwa angidingi uhlelo ukuthi lunginqumele okuthile. Shiya uhlelo, izinhlelo zokusebenza kanye nedatha ku-SSD futhi yonke into isuke ishesha ngendlela exakile.
Ukudlala ividiyo akudingi i-SSD, ngakho nginawo wonke amavidiyo ku-HDD. Futhi izithombe zoqobo, umculo, izipele nezifaki.
Ukubuka izithombe kungcono ku-SSD, ngakho-ke nginamakhophi azo ngefomu elincishisiwe elingu-2Mpix ku-SSD.
I-SSD nayo izosiza kakhulu ngokuhlela ividiyo, ngakho-ke ngihambisa amavidiyo engifuna ukuwahlela ku-SSD okwesikhashana.
I-128GB SSD + 2TB+ HDD (5400 rpm) ingilungele
Nansi indlela ongayenza ngayo iMacbook Pro, iMac Mini nePC.
Yebo, ingaxazululwa ngale ndlela, kodwa abasebenzisi abaningi banokudideka kudatha yabo, bheka nje umtapo wabo we-iTunes... Yingakho i-Fusion Drive ibonakala inenzuzo kubo. Kodwa sizozishiya ngempela iziphetho kamuva :)
Hhayi-ke, khululeka, uma ubuchopho bami be-nitpicky bucabanga ukugcina i-maglazju ezingxenyeni ezingahlelekile (noma kumadiski) ngifuna ukuhlanza. I-Fusion Drive cishe ingangisiza kangcono :)
