Puas yog koj lub koob npe zoo rau tus neeg koom rau APFS?
APFS (Apple File System) yog ib qho tshiab ua haujlwm rau SSDs (Tau-State Drives) thiab Flash li USB thumb drives. Thiab txawm hais tias nws yog tig los ntawm lub cev nqaij daim tawv tshwj xeeb rau flash-raws cia, nws kuj yog tsom raws li ib qho dav dav cov ntaub ntawv system hloov rau txhua tus cia cia.
APFS siv rau tag nrho cov kev khiav hauj lwm lub iPad xws li watchOS , tvOS , iOS , thiab macOS . Txawm tias feem ntau ntawm Apple operating systems siv tsuas yog lub cev cia lub xeev xwb, macOS muaj peev xwm ua tau siv nrog kev kaw lus cia, nrog rau cov twj siv kho qhov muag, USB ntiv tes xoo , lub xeev cov drives, thiab platter-based hard drives.
Nws yog qhov ntau ntawm MacOS thiab tag nrho ntawm cov kev xaiv cia muaj rau nws uas peb tau nug cov lus nug no: Yuav tsum APFS siv rau tag nrho cov disk hom kev txhawb los ntawm macOS?
Hom Disks twg yog qhov zoo tshaj plaws rau kev siv nrog APFS?
Txij li thaum APFS tau tsim los siv SSDs thiab flash-based cia nws yuav pom tseeb tias cov ntaub ntawv tshiab yuav zoo nyob hauv tsev ntawm cov khoom siv tshiab thiab ceev tshaj plaws. Rau qhov feem ntau, koj yuav tsum yog, tab sis nws muaj cov kev siv tau uas ua rau APFS tsis zoo, lossis tsawg dua ib qho kev xaiv kom zoo li cov ntaub ntawv siv los siv.
Cia wb xav saib APFS tsis zoo li cas rau hom qes hom thiab kev siv.
APFS ntawm Kev Tsav Xwm Tsav Xeev
- Yog-APFS rau ntawm lub xeev-state drives theem tawm qhov zoo tshaj plaws ntawm cov ntaub ntawv tshiab.
Pib nrog macOS High Sierra, SSDs siv raws li startup drives yuav txav mus rau APFS thaum OS yog kho dua tshiab. Qhov no yog qhov tseeb ntawm sab hauv SSDs, thiab sab nraud SSDs txuas ntawm Thunderbolt. USB raws li sab nraud SSDs yuav tsis cia li hloov dua siab tshiab, txawm tias koj tuaj yeem hloov tau lawv mus rau APFS yog tias koj xav tau.
APFS yog qhov ua kom zoo rau cov xeev-tsav drives thiab flash-based systems xws li USB thumb drives. Hauv kev ntsuam xyuas, APFS pom cov kev ua tau zoo dua qub thiab kev nce qib hauv kev khaws cia ua rau muaj ntau qhov chaw dawb. Qhov chaw cia khoom tau los ntawm nta tau-ua rau APFS xws li:
- Clones uas tau tsim yuav luag tam sim ntawd tsis tau mus txog ib qho chaw twg ntxiv chaw cia.
- Kev sib koom chaw pub ntau qhov sib faib chaw dawb nyob rau hauv ib lub thawv APFS.
- Luam-rau-Sau ntawv uas tso cai rau cov ntaub ntawv qhia tawm thaum tsis muaj kev hloov.
- Sib Txawv Cov Ntaub Ntawv ntau txoj hauv kev tswj cov chaw dawb.
APFS ceev nquag nrog cov xeev-drives yog pom tsis tsuas yog hauv lub sijhawm khau raj, uas tau qhia ua txoj kev txhim kho, tiam sis tseem muaj cov ntaub ntawv luam, uas ua tsaug rau cloning yuav ua tsis tau sai sai.
APFS rau Fusion Drives
- Tsis yog-Fusion drives tsis yog ib tus neeg sib tw rau txoj kev txhawb nqa APFS.
Nws zoo nkaus li lub hom phiaj ntawm APFS yog ua haujlwm tsis nrog ob qho nyuaj drives thiab SSDs. Thaum lub caij pib beta versions ntawm macOS High Sierra, APFS yog muaj los nruab rau SSDs, nyuaj drives, thiab kua kua khi cia, lub Fusion tsav thaum lawv tseem me me tab sis SSD ceev nrog nrog lub loj tab sis qeeb nyuab tsav.
Fusion tsav kev ua haujlwm thiab kev cia siab rau APFS seemed tuaj rau hauv nqe lus nug thaum lub sij hawm betas ntawm macos High Sierra thiab thaum kev khiav hauj lwm raug tso tawm rau APFS ntawm Fusion drives tau rub tawm, thiab lub lag luam tshuab disk utility twb raug kho kom tiv thaiv Fusion drives los ntawm kev hloov mus rau APFS hom ntawv.
Speculation pib taw mus rau ib qhov teeb meem kev cia siab nrog hloov cov kabmob uas twb muaj lawm Fusion rau APFS hom ntawv. Tab sis qhov tiag tiag qhov teeb meem tej zaum yuav yog ib tug kev ua tau zoo cuam tshuam los ntawm lub zog tsav ntawm Fusion khub. Ib qho ntawm cov qauv ntawm APFS yog ib qho txheej txheem tshiab los xyuas cov ntaub ntawv tiv thaiv hu ua Copy-on-Write. Luam-rau-Sau ntawv khaws cov ntaub ntawv poob qis rau qhov tsawg kawg los ntawm kev tsim ib daim ntawv tshiab ntawm cov ntawv ntaws uas tau hloov (sau ntawv). Nws mam li hloov cov ntaub ntawv pointers rau cov ntawv tshiab tom qab sau ntawv tiav. Thaum uas qhov no saib xyuas cov ntaub ntawv yog kev tiv thaiv thaum sau ntawv, nws tuaj yeem ua rau ntau ntau ntawm cov ntaub ntawv segmentation, scatter qhov chaw ntawm cov ntaub ntawv nyob ib ncig ntawm lub disk. Nyob rau hauv lub xeev tau tsav, qhov no tsis yog ntau qhov kev txhawj xeeb, ntawm ib tus tsav nyuaj, nws tuaj yeem ua rau disk fragmentation thiab txo cov kev ua tau zoo .
Nyob rau hauv Fusion tsav, cov ntaub ntawv theej luam tau tshwm sim ntau zaus vim yog ib qho ntawm cov haujlwm ntawm khi cia yog txav cov ntaub ntawv uas nquag siv los ntawm qeeb qeeb qeeb tsav mus rau SSD sai thiab tau qiv dua feem ntau siv cov ntaub ntawv los ntawm SSD rau lub zog tsav. Tag nrho cov kev luam no yuav ua rau muaj teeb meem ntawm fragmentation ntawm lub tsav nyuab thaum APFS thiab Luam-rau-Sau tau raug siv.
Kua tau cog lus tseg tias APFS yuav qee lub neej yav tom ntej yuav npaj siv rau Fusion thiab tiered cia lub tshuab, uas yoojyim peb nrog rau lo lus nug seb ua li cas APFS ua haujlwm nrog tus qauv nyuaj tsav.
APFS ntawm Nyuaj Drives
- Tej zaum-APFS yuav siv tau rau hauv cov tsav nyuaj, tab sis yog qhov txiaj ntsim tsawg me ntsis.
Koj tuaj yeem siv APFS rau ntawm koj tus tsav nyuaj yog tias koj siv Cov Ntaub Ntawv Vault los encrypt koj tsav . Hloov mus rau APFS kuj tseem yuav hloov Cov Ntaub Ntawv Vault Encryption nrog ntau qhov kev ruaj ntseg encryption system uas yog built-in mus rau APFS system.
Kuv xav tias Apple lub hom phiaj rau APFS ntawm kev tsav nyuab siab yog tsis tuaj leej twg, tus neeg siv yuav tsum tsis txhob pom ntau hauv txoj kev txhim kho feem ntau, tab sis yeej tsis pom cov kev teeb tsa ntawm kev ua tau zoo. Hauv kev xav, APFS ntawm lub zog tsav tsheb yuav tsum muaj kev txhim kho rau cov ntaub ntawv kev nyab xeeb thiab kev ruaj ntseg yam tsis muaj kev cuam tshuam cov teeb meem kev kawm.
Nws tshwm sim, rau qhov feem ntau, APFS tau ntsib lub hom phiaj no tsis zoo rau kev tsav nyuaj, tab sis muaj qee qhov chaw ntawm kev txhawj xeeb. Rau kev siv xam phaj xws li ua haujlwm nrog emails, sau ntawv ua haujlwm, saib xyuas lub vas sab, ua kev tshawb fawb, ua si hauv ob peb games, mloog nkauj, saib yeeb yaj duab, ua haujlwm nrog cov duab thiab yeeb yaj duab yuav tsum ua haujlwm zoo rau APFS.
Qhov uas qhov teeb meem tuaj yeem tshwm sim tau yog thaum cov yeeb yaj kiab uas ua yeeb yam dhau los, xws li cov duab thaij duab thiab cov yeeb yaj duab ua ntu zus, lossis ib tus neeg ua haujlwm nrog lub suab, tsim podcasts, lossis kho cov suab nkauj. Txhua yam kev ua haujlwm uas muaj cov ntaub ntawv sau ua ntaub ntawv loj loj.
Nco ntsoov Fusion drive thiab Copy-on-Write qhov teeb meem uas yuav ua rau disk fragmentation? Tib qhov teeb meem tshwm sim thaum APFS raug siv rau hauv cov tsav nyuaj uas siv hauv ib qho kev tawm tsam xov xwm dav dav.
Qhov zoo tshaj plaws, leej twg ua txoj hauj lwm no muaj peev xwm twb tsiv lawv lub Mac mus rau SSD raws kev ceev xwm txheej. Tab sis kuj tseem muaj ob peb leej neeg uas yuav siv kev tsav nyuaj raws li RAID cia kom ua tau raws li qhov lawv xav tau kho. Yog li ntawd, APFS thiab Copy-on-Write yuav ua rau muaj kev degradation ua haujlwm thaum lub sijhawm ua rau cov tsav poob haujlwm.
APFS rau ntawm Externals
- Tej zaum tsis yog ib lub tswv yim zoo-Yog tias koj tsav sab nraud (xws li USB thumb drive) tau sib koom nrog ntau Macs los yog cov platform hauv kev lag luam uas koj xav kom tsis txhob hloov lawv mus rau APFS.
APFS hom ntawv tsav tsheb tam sim no tsuas yog nkag tau los ntawm Macs khiav Sierra los sis Sierra Sierra operating system. Yog tias koj lub hom phiaj yog sib qhia cov ntaub ntawv ntawm lwm tus tsav tsheb, nws yog qhov zoo tshaj rau cov tawm hauv cov txheej txheem ua ntau hom xws li HFS +, FAT32 los yog ExFAT.
Lub sij hawm Tshuab Drives
- Tsis muaj lub sij hawm cav yuav tsum tau tsav nrog cov HFS + cov ntaub ntawv.
Yog hais tias koj xav hloov lub sij hawm tshuab tsav mus rau APFS lub sij hawm Machine app yuav plam ntawm qhov thaub qab ntxiv. Tsis tas li ntawd, cov ntaub ntawv ntawm lub sij hawm Tshuab tsav yuav tau muab tshem tawm los ua tus tsav rov qab mus rau HFS rau kev siv nrog Time Machine.
