Dynamic cache
Kev lig kev cai, txhua qhov kev tshuaj xyuas tsav suav nrog DRAM cache tag nrho kev sim ua raws li kev tshaj tawm ntawm nws qhov loj me, tab sis qhov no yog cov lus tsis tseeb. Tus qauv qhov ceev ceev tsis yog faib dynamically tsis tsuas yog raws li ib feem ntawm qhov chaw dawb xwb, tab sis kuj raws li hom ntaub ntawv sau.
Piv txwv li, cia peb sim sau tag nrho cov disk nrog cov ntaub ntawv nrog cov ntaub ntawv random. Cov ntaub ntawv no muaj cov ntaub ntawv compressible thiab tsis-compressible hauv cov blocks sib txawv. Txoj kev xav, qhov ceev tsis txaus yuav tsum txaus rau 100-200 GB, tab sis raws li koj tuaj yeem pom, qhov tshwm sim txawv. Ib qho tseem ceeb poob rau hauv cov ntaub ntawv kaw tseg tsuas yog tshwm sim ntawm 400+ GB cim, uas qhia peb txog cov txheej txheem kaw suab tswj cov txheej txheem ntawm firmware. Lub sijhawm no, nws paub meej tias qhov twg tus txiv neej-teev mus rau hauv kev tsim KC2500. Yog li, SLC cache ntawm KC2500 tsav muaj kev faib tawm thiab nyob ntawm ntau yam, tab sis nws yeej tsis txwv rau 150-160 GB.
Hom kev nkag mus rau SSD OS Windows 10
Qhov yuam kev thib ob yog tsis cia tus nyeem ntawv nkag siab txog dab tsi nkag mus rau hauv disk yog tias koj siv nws ua qhov system disk. Ntawm no dua, txoj hauv kev kom raug rau kev ntsuam xyuas yog qhov tseem ceeb. Kuv mam li sim rov ua qhov haujlwm li niaj zaus hauv kev ua haujlwm raws li tus neeg siv. Ua li no, peb yuav rho tawm ib yam dab tsi rau lub thoob khib nyiab, qhib lub kaum os cov ntaub ntawv hauv Photoshop, ib txhij khiav disk ntxuav, xa tawm los ntawm Excel, thawj zaug qhib ob peb lub rooj, thiab txuas ntxiv sau cov ntawv no. Kev sib txuas ntawm kev hloov tshiab tsis txaus, tab sis qhov ntawd tsis yog, cia peb khiav qhov hloov tshiab ntawm Chav.
Hauv yuav luag 10 feeb ntawm kev ua haujlwm, ntau dua 90% ntawm kev thov tau cuam tshuam nrog kev nyeem cov ntaub ntawv hauv 4K blocks, thiab yuav luag ib nrab ntawm cov ntawv sau hauv tib lub blocks. Kuv nco ntsoov tias cov ntaub ntawv paging hauv Windows ib puag ncig yog qhov kev txiav txim siab ntawm qhov system. Zuag qhia tag nrho, daim duab qhia tau hais tias nws tsis yog qhov nrawm heev uas tseem ceeb rau kev ua haujlwm, tab sis lub sijhawm teb rau cov haujlwm me me. Ntxiv mus, qhov ntim ntawm cov haujlwm no tsis loj heev. Lawm, koj yuav tsum xav txog kev yuav SSD ceev rau kev ua si (thaum thauj cov games lawv tus kheej thiab kev ceev ntawm kev sau ntawv tshiab kuj tseem ceeb). Thiab raws li lwm daim ntawv, nws yog qhov zoo kom tau txais cov kab siab nyeem / sau nrawm thaum nws tuaj yeem luam tawm lossis sau cov ntaub ntawv.
