Apple File System rau macOS optimizes nkag mus rau cov khoom siv hauv xeev thiab cov khoom siv flash xws li USB ntiv tes xoo. APFS yog siv rau txhua lub Apple operating systems, suav nrog watchOS, tvOS, iOS, thiab macOS. Thaum feem ntau Apple operating systems siv tsuas yog cov khoom siv hauv lub xeev cia, macOS muaj peev xwm siv txhua qhov chaw cia, suav nrog optical discs, USB ntiv tes xoo drives, solid-state drives, thiab platter-based hard drives.
Hom Disks twg yog qhov zoo tshaj plaws rau APFS?
Vim tias APFS yog thawj zaug tsim los siv nrog SSDs thiab flash-based cia, nws yuav zoo li tias cov ntaub ntawv tshiab yuav nyob hauv tsev ntawm cov tshuab khaws cia tshiab thiab ceev tshaj plaws. APFS ua haujlwm nrog ntau lub tshuab khaws cia, tab sis muaj cov kev siv tshwj xeeb uas tuaj yeem ua rau APFS xaiv tsis zoo, lossis tsawg kawg yog qhov tsawg dua qhov kev xaiv zoo.
Cia peb saib seb APFS haum li cas rau hom disk thiab kev siv.
APFS ntawm Solid-State Drives: Yog
Pib nrog macOS High Sierra, SSDs siv los ua cov tsav tsheb pib tau hloov pauv mus rau APFS thaum OS hloov kho dua tshiab-xws li SSDs sab hauv thiab sab nraud SSDs txuas nrog siv Thunderbolt. USB-raws li lwm SSDs tsis tau hloov dua siab tshiab, txawm hais tias koj tuaj yeem hloov cov no rau APFS.
APFS ntawm cov khoom siv hauv lub xeev coj tawm qhov zoo tshaj plaws ntawm cov ntaub ntawv tshiab.
Hauv kev sim, APFS tau pom tias muaj kev ua tau zoo dua qub thiab tau txais txiaj ntsig hauv kev khaws cia, ua rau muaj ntau qhov chaw dawb. Qhov chaw cia khoom tau txais los ntawm cov yam ntxwv ua rau hauv APFS, suav nrog:
- Clones: Clones tsim yuav luag tam sim ntawd yam tsis tau noj qhov chaw tseem ceeb ntxiv.
- Space Sharing: Ntau lub ntim qhia qhov chaw dawb hauv lub thawv APFS.
- Copy-on-Write: Cov ntaub ntawv qhia qhia thaum tsis muaj kev hloov pauv.
- Sparse Files: Cov ntaub ntawv no muab txoj hauv kev zoo dua los tswj qhov chaw dawb.
APFS nrawm nrawm nrog cov khoom siv hauv xeev tau pom hauv lub sijhawm khau raj, uas tau pom tias muaj kev txhim kho zoo, thiab nrog kev luam cov ntaub ntawv, uas vim yog cloning, tuaj yeem nrawm.
APFS ntawm Fusion Drives: Tsis yog
Lub hom phiaj tseem ceeb ntawm APFS yog ua haujlwm tsis sib haum nrog ob lub hard drives thiab SSDs. Thaum lub sijhawm pib beta versions ntawm macOS High Sierra, APFS muaj rau nruab rau ntawm SSDs, hard drives, thiab ntawm Apple tired cia tov, Fusion Drive. Fusion Drive yog ib qho kev sib txuas ntawm qhov me me tab sis ceev SSD nrog rau lub hard drive loj tab sis qeeb.
Fusion Drives tsis yog tus neeg sib tw rau kev txhim kho rau APFS system.
Fusion Drive kev ua tau zoo thiab kev ntseeg siab nrog APFS zoo li los rau lo lus nug thaum lub sijhawm betas ntawm macOS High Sierra. Thaum lub operating system raug tso tawm rau pej xeem, kev txhawb nqa rau APFS ntawm Fusion drives raug rub, thiab cov kev khiav hauj lwm qhov chaw siv hluav taws xob tau hloov kho los tiv thaiv Fusion Drives los ntawm kev hloov mus rau APFS hom.
Kev ntsuas taw qhia rau qhov teeb meem kev ntseeg siab nrog hloov Fusion Drives uas twb muaj lawm mus rau hom APFS. Tab sis qhov kev sib tw tiag tiag yuav yog qhov kev ua tau zoo raug coj los ntawm hard-drive feem ntawm Fusion khub. Ib qho ntawm cov yam ntxwv ntawm APFS yog cov txheej txheem tshiab los xyuas kom meej cov ntaub ntawv tiv thaiv hu ua Copy-on-Write. Luam-on-Write khaws cov ntaub ntawv poob mus rau qhov tsawg kawg nkaus los ntawm kev tsim ib daim ntawv theej tshiab ntawm txhua ntu uas tau hloov kho (sau). Nws mam li hloov kho cov ntaub ntawv taw qhia rau cov ntawv theej tshiab tom qab sau tiav tiav. Thaum txoj hauv kev no tiv thaiv cov ntaub ntawv thaum lub sijhawm sau ntawv, nws tuaj yeem ua rau cov ntaub ntawv segmentation, tawg qhov chaw ntawm cov ntaub ntawv nyob ib ncig ntawm lub disk.
Nyob rau hauv lub xeev kev tsav tsheb, qhov no tsis muaj kev txhawj xeeb ntau. Ntawm lub hard drive, nws tuaj yeem ua rau disk fragmentation thiab txo kev ua haujlwm. Ntawm Fusion tsav, kev theej cov ntaub ntawv feem ntau tuaj yeem tshwm sim vim tias ib qho ntawm cov haujlwm ntawm kev khaws cia yog txav cov ntaub ntawv nquag siv los ntawm lub zog qeeb qeeb mus rau qhov nrawm dua SSD, thiab cov ntaub ntawv tsis tshua muaj los ntawm SSD mus rau lub hard drive. Tag nrho cov kev luam no tuaj yeem ua rau muaj kev cuam tshuam tsis zoo ntawm lub hard drive thaum siv APFS thiab Copy-on-Sau.
APFS ntawm Hard Drives: Tej zaum
Koj yuav xav siv APFS ntawm koj lub hard drive yog tias koj siv File Vault los encrypt koj tsav. Hloov mus rau APFS hloov cov ntaub ntawv Vault encryption nrog cov txheej txheem encryption muaj zog dua uas tau tsim rau hauv APFS system.
APFS tuaj yeem siv rau ntawm hard drives, txawm tias qhov txiaj ntsig me me.
Apple lub hom phiaj rau APFS ntawm lub hard drive yog qhov nruab nrab. Tsis muaj ntau txoj hauv kev txhim kho kev ua tau zoo, tab sis kuj tsis muaj ntau degradation ib yam. Hauv qhov tseem ceeb, APFS ntawm lub hard drive yuav tsum muab kev txhim kho dav dav hauv cov ntaub ntawv kev nyab xeeb thiab kev nyab xeeb yam tsis muaj teeb meem kev ua haujlwm.
Rau feem ntau, APFS tau ua tiav lub hom phiaj kev ua haujlwm nruab nrab no rau cov tsav nyuaj, txawm tias muaj qee qhov kev txhawj xeeb. Rau kev siv suav nrog xws li kev ua haujlwm nrog email, sau cov ntaub ntawv hauv chaw ua haujlwm, tshawb xyuas lub vev xaib, ua haujlwm tshawb fawb, ua si ob peb yam, mloog nkauj, saib yeeb yaj kiab, thiab ua haujlwm nrog cov duab, cov kev siv no ua haujlwm zoo ntawm APFS-formatted nyuaj. tsav.
Teeb meem tuaj yeem tshwm sim thaum ua qhov kev hloov kho dav dav, xws li hauv duab, yees duab, lossis suab software-txhua yam haujlwm uas tau ua tiav cov ntaub ntawv loj.
Qhov Fusion Drive thiab Copy-on-Sau kev sib tw tuaj yeem ua rau disk tawg. Tib qhov xwm txheej tshwm sim thaum APFS siv rau ntawm hard drives uas siv rau kev tshaj tawm xov xwm.
Feem ntau cov neeg ua haujlwm hom kev siv peev txheej no feem ntau yuav hloov lawv Mac mus rau SSD-raws li qhov system cia. Txawm li cas los xij, muaj qee tus uas yuav siv zog-tsav-raws li RAID cia tshuab kom tau raws li lawv cov kev xav tau kho. Nyob rau hauv tas li ntawd, APFS thiab Copy-on-Sau tej zaum yuav ua rau kev ua hauj lwm degradation nyob rau lub sij hawm raws li cov drives ua fragmented.
APFS ntawm Sab Nraud: Tej zaum Tsis yog
APFS-formatted drives tam sim no tsuas yog nkag tau los ntawm Macs nrog Sierra operating system lossis tshiab dua. Yog tias koj npaj siab yuav qhia cov ntaub ntawv ntawm ib lub tsav sab nraud nrog ntau lub khoos phis tawj-tshwj xeeb Windows thiab Linux tshuab-tawm cov drives formatted hauv cov ntaub ntawv sib xws, xws li HFS+, FAT32, lossis ExFAT.
Yog tias koj cov tsav sab nraud (xws li USB tus ntiv tes xoo drives) tau koom nrog ntau lub Macs lossis lub khoos phis tawm, tsis txhob hloov cov tsav mus rau APFS.
Lub Sijhawm Tshuab Tsav: Tsis yog
Yog tias koj yuav hloov lub Sijhawm Tshuab Tsav rau APFS, Lub Sijhawm Tshuab app yuav ua tsis tiav ntawm qhov thaub qab tom ntej. Tsis tas li ntawd, cov ntaub ntawv ntawm Lub Sijhawm Tshuab Tsav yuav tsum tau muab tshem tawm kom format lub tsav rov qab rau HFS + siv nrog Lub Sijhawm Tshuab.
Lub Sijhawm Tshuab yuav tsum tau tsav formatted nrog HFS + cov ntaub ntawv kaw lus.
