Mayelana nalolu hlelo lokusebenza

Qaphela: kuphela ukuhlolwa kwememori kwangaphakathi okutholakala ku-Android 11.

I-CPDT (i-Cross Platform Disk Test) uhlelo lokusebenza lokulinganisa uhlelo lokusebenza olulinganisa isivinini se-I / O sokugcina unomphela (imemori yangaphakathi / i-NAND / NVMe / i-UFS / ikhadi le-SD) nememori yohlelo (RAM).

Lolu hlelo lokusebenza lune-Windows, i-MacOS ne-Linux v̲e̲r̲s̲i̲o̲n̲s̲ evumela ukuthi kuqhutshwe ukuhlolwa ngokungaguquki kuwo wonke amadivayisi nezinhlelo zokusebenza. Zingalandwa kuwebhusayithi: https://maxim-saplin.github.io/cpdt_results/?download

Isizindalwazi semiphumela yangaphakathi nohlelo senza sikwazi ukuqhathanisa ukusebenza kwefoni yakho namanye ama-smartphones e-Android (isb. Samsung Galaxy Note 10, Xiaomi Redmi 7 njll.) Nezinhlobonhlobo zezingxenyekazi zekhompuyutha (iPhones, Macs, Windows PCs, Android TV Players njll

Indawo yokubekisa ibandakanya lezi zivivinyo ezi-5 ezilandelayo:

Tests Ukuhlolwa kokugcina unomphela
┊
Write ◎ Ukubhala ngokulandelana
┊
Read ◎ Ukufundwa ngokulandelana
┊
Ukubhala okungahleliwe (ibhulokhi le-4KB)
┊
Funda okungahleliwe (ibhulokhi le-4KB)

Ukuhlolwa kwe-RAM
┊
Ikhophi yememori

- Imiphumela yokuhlolwa inikezwa njengamanani we-throughput alinganiswa nge-MB / s (megabytes ngomzuzwana).

Izilungiselelo ezahlukahlukene ziyatholakala kwimenyu yezinketho bese uvumela abasebenzisi balawule:

◉ Usayizi wefayela lokuhlola
┊
I-GB ◎ 0.5GB ◎ ◎ 1GB ┄ ◎ 2GB ┄ ◎ 4GB ┄ ◎ 8GB ┄ ◎ 16GB

◉ Bhala ukubhafa
┊
Kuvuliwe ┄ ◎ Cishiwe

C Ukulondolozwa kwesikhashana sefayela
┊
Kuvuliwe ┄ ◎ Cishiwe

Ukuhlolwa okulandelanayo uhlelo lokusebenza lakha amagrafu ochungechunge lwesikhathi, ngokuhlolwa okungahleliwe - ama-histograms. Imiphumela yokuhlola ingathunyelwa ku-CSV ukuze ihlaziyeke ngokwengeziwe (umugqa ngamunye uqukethe indawo evimba kufayela lokuhlola nokukalwa kwendlela).

Ihluke kanjani i-CPDT kwezinye izinhlelo zokusebenza? Amabhentshimakhi athandwa kakhulu agxila ku-CPU / GPU (njengeGeekbench, AnTuTu) futhi angakunaki ngokuphelele ukusebenza kwesitoreji.

Isitoreji namabhentshi wememori akuvamile ukuthi abasebenzisi bashintshe noma iziphi izilungiselelo futhi bakhawulelwe ekucaciseni usayizi wefayela lokuhlola. Ukulawula ukubhafa noma ukulondolozwa kwesikhashana akunakwenzeka (isb.Androbnech) noma kudinga ukulayishwa kabusha kwedivayisi (isb. A1 SD).

Ukulondolozwa kwesikhashana kuyindlela ethonya kakhulu imiphumela yokuhlolwa. Uma ngabe ku-ON imiphumela yokuhlolwa ithinteka ngejubane le-RAM futhi akunakwenzeka ukuhlukanisa ukusebenza kwesitoreji unomphela ezivivinyweni ezinjalo. Izimo ezibandayo zokufunda (isb. I-boot yedivayisi noma ukuqala kwesicelo sokuqala) azikwazi ukuchazwa ngokufundwa okulondoloziwe. Isimo esifanayo sinokubhafa okuthinta ukuhlolwa kokubhala. Ukubhafa isebenzisa i-RAM yokugcina idatha yesikhashana ngaphambi kokuyiphikelela ekugcineni.

I-CPDT isebenzisana nokulondolozwa kwesikhashana kanye nokubhafa futhi ngokuzenzakalela lezo zivaliwe ezenza kube lula ukukala ngokungaguquki nokuqhathanisa ukusebenza kwesitoreji unomphela kuwo wonke amadivayisi nezinhlelo zokusebenza.

Kungani ukugcina nokusebenza kwememori kubalulekile? Lithinta ngqo izinga lokusebenza "okubonakalayo". I-UI efriza ingachazwa ezimweni eziningi ngama-stutter asezingeni lesitoreji. Isb. ibonisa ikhasi lewebhu elilayishiwe esipheqululini lapho icela idatha kusuka kudiski, iskrola izithombe kuhlelo lokusebenza lwegalari (imaging ukupheqa izinkulungwane zazo), noma ukwehla okuphakelayo kwe-Instagram (izithombe ezilayishwe ngaphambilini zizocelwa kusuka kunqolobane egcinwe kudiski).

Abasebenzisi be-Chromebook bangasebenzisa lolu hlelo lokusebenza ngemuva kokunika amandla i-Google Play. Ukuze ufinyelele ku-SD / Memory Card uhlelo lokusebenza kumele lunikezwe "imvume yesitoreji" kuzilungiselelo ze-Google Play ze-Chrome OS.

Ukuxhaswa kwe-OTG akuqinisekisiwe! Uma uxhuma isifundi sekhadi langaphandle noma i-USB flash drive kudivayisi yakho, ingahle isebenze noma ingahle ingasebenzi. Isb. I-Samsung Galaxy S8 ene-Android 8 ne-Note 10 ene-Android 10 isebenza kahle. I-Xiaomi Mi8SE (i-Android 9), i-Meizu 16 (i-Android 8.1) ne-LG Nexus 5x (i-Android 6) ayisebenzi (yize usazokwazi ukubona idrayivu ohlelweni). Kungani kunjalo? I-Android OS ayinayo imodeli engaguquguquki esebenza namadivayisi wesitoreji axhunywe ngaphandle. Abanye abakhiqizi bedivayisi benza umsebenzi omuhle (njenge-Samsung) ngokufaka kahle idivayisi nokwenza ukuthi itholakale nge-default API (Context.getExternalFilesDir ()). Abanye badinga amaqhinga noma basebenzise ama-API athile wokukhiqiza.
