Informatec Digital » Izinsiza » I-SSD vs NVMe: umehluko wangempela, izinzuzo kanye nokuthi kufanele ukhethe nini ngayinye

Kungakhathaliseki ukuthi wakha i-PC entsha noma ufuna ukunika ikhompyutha yakho impilo yesibili, lokhu kungokwakho.Ukukhetha isitoreji akuseyona into elula njengokuthi "vele ufake i-hard drive bese uqedile." Phakathi kwama-acronym, amafomethi, kanye namaphrothokholi (i-SSD, i-NVMe, i-SATA, i-M.2, i-PCIe…), kulula ukudideka bese ugcina uthenga into engasebenzisi ngokugcwele uhlelo lwakho… noma ekhokha ngokweqile.

Umbuzo ojwayelekile namuhla ucacile: i-SSD vs i-NVMe, iyiphi ebaluleke kakhulu? Zombili ziyi-solid-state drives, kodwa azisebenzi ngendlela efanayo, azixhumani ngendlela efanayo, noma azinikezi ukusebenza okufanayo. Sizohlukanisa wonke umehluko sisebenzisa idatha yangempela, izibonelo zansuku zonke, kanye nemininingwane yobuchwepheshe, kodwa ngolimi olucacile nolufinyeleleka kalula ngangokunokwenzeka.

Iyini i-SSD futhi kungani yashintsha ama-hard drive?

I-SSD (i-Solid State Drive) iyisitoreji esisekelwe kumemori ye-flash okuthatha indawo yama-hard drive endabuko (ama-HDD). Esikhundleni sokusebenzisa ama-plate ajikelezayo nama-read/write heads, i-SSD isebenza ngama-memory chips angaguquki (i-NAND flash), afana kakhulu nalawo aku-USB flash drive noma imemori yangaphakathi yefoni ephathekayo, kodwa ashesha, ahlala isikhathi eside, futhi ayinkimbinkimbi kakhulu.

Inzuzo enkulu yama-SSD kune-HDD kwakuwukukhuphuka okukhulu kwesivininiAma-hard drive endabuko ayenezikhathi zokufinyelela ezinde kakhulu futhi ashesha kakhulu ukufunda/ukubhala. Ngokufaka i-SSD kukhompyutha endala, isikhathi sokuqalisa i-Windows sasuka kumzuzu owodwa saya kumasekhondi ambalwa nje, izinhlelo zavuleka ngokushesha okukhulu, futhi uhlelo lwazizwa "lulula" yize iprosesa yayingeyintsha.

Ngokomlando, ama-SSD okuqala ayebiza kakhulu futhi ayenamandla aphansi.Kodwa ngokuhamba kwesikhathi, ubuchwepheshe be-flash bavuthwa, izindleko zokukhiqiza zehla, futhi namuhla kungenzeka ngokuphelele ukuthola ama-drive angu-1 TB ngamanani afanele, kufaka phakathi amadrayivu e-SSD amancane, asheshayo futhi athembekileYingakho sebeyindinganiso cishe kunoma iyiphi i-PC efuna ukunikeza ulwazi oluhle.

Ngaphakathi kwesigaba se-SSD akukhona uhlobo olulodwa kuphela, kodwa kunemindeni eminingana kuye ngefomethi ebonakalayo kanye nendlela yokuxhuma: i-2,5” SATA SSD, i-M.2 SSD, i-PCIe SSD ngefomethi yekhadi, njll. Futhi yilapho kuqala khona ukudideka nge-NVMe, ngoba i-NVMe akuyona uhlobo “lwediski yomlingo” oluhlukile kuma-SSD, kodwa yingxenye yendlela axhuma futhi axhumana ngayo.

Izici zefomu le-SSD: 2,5”, M.2 kanye nezinye izinhlobo

Uma sikhuluma "ngesici sefomu" sibhekisela esimweni somzimba kanye nosayizi we-SSDOkusho ukuthi, idivayisi ibukeka kanjani ngaphandle nokuthi ixhumeka kanjani kukhompyutha. Ekhaya, ezivame kakhulu yilezi:

• I-SSD engu-2,5”Zilingana nosayizi wama-hard drive e-laptop, zifakwe ezindaweni ezivulekile, futhi zixhunywe ngezintambo.
• M.2 SSD: Lawa amabhodi amancane, amade, afana ne-RAM memory stick enwetshiwe, afakwe izikulufo ngqo kubhodi lomama.
• I-SSD mini-SATA (mSATA) kanye namanye amafomethi athile: ayivamile kulezi zinsuku, itholakala kakhulu emishinini emidala noma emincane kakhulu.

Ifomethi engu-2,5” isithandwa kakhulu ngoba ifanela kokubili amakhompyutha edeskithophu kanye nama-laptop. futhi isebenzisa njalo i-interface yendabuko ye-SATA. Ixhuma nge- Ikhebuli yedatha ye-SATA eyodwa iye kubhodi lomama kanti enye ivela kugesi, njenge-HDD, kodwa ngaphakathi kunememori ye-flash esikhundleni sediski yomshini.

Okwamanje, ifomethi ye-M.2 isithole amandla ngoba igcina isikhala namakhebula.Idrayivu ixhuma ngqo kwisikhala se-M.2 kubhodi lomama, isusa isidingo sezintambo, okwenza kube lula ukufaka futhi kuthuthukise ubuhle bangaphakathi. Yindlela ejwayelekile kuma-laptops anamuhla kanye nama-PC amaningi edeskithophu amanje.

Nansi enye yezinkinga ezivame kakhulu: akuwona wonke ama-SSD e-M.2 ayi-NVMeI-M.2 SSD ingasebenza isebenzisa iphrothokholi ye-SATA kanye ne-interface (ebizwa ngokuthi i-M.2 SATA) noma ingaba yi-M.2 NVMe SSD esebenzisa imizila ye-PCIe. Ngokwemvelo zibukeka zifana kakhulu, kodwa ngaphakathi ukusebenza kuhlukile kakhulu.

I-Interface, ibhasi kanye nephrothokholi: i-SATA, i-PCI Express, i-AHCI kanye ne-NVMe

Ukuze uqonde kahle impi ye-SSD vs NVMe, imiqondo emithathu idinga ukuhlukaniswa. okuvame ukuxutshwa: uhlobo lokuxhumana okungokoqobo (isikhombikubona noma ibhasi), iphrothokholi yokuxhumana, kanye nedivayisi yokugcina izinto uqobo.

I-interface noma ibhasi ledatha "indlela" lapho ulwazi luhamba khona Kusukela ku-SSD kuya kulo lonke uhlelo. Ezweni lama-PC asekhaya, sinamabili kakhulu:

• I-SATA (Serial ATA)I-SATA yavela cishe ngo-2003 ukuze ithathe indawo ye-IDE/PATA, ngamakhebula amancane, izindleko eziphansi, kanye nesivinini esiphezulu. Inguqulo ye-SATA III (leyo esiyisebenzisa namuhla) inesivinini esilinganiselwe esingaba ngu-600 MB/s.
• I-PCI Express (PCIe)Leli yibhasi lesivinini esikhulu elisetshenziswa namakhadi ehluzo. Linikeza "imizila" eminingana (x1, x4, x8, x16) kanye nezinguqulo (3.0, 4.0, 5.0), ngayinye iphinda kabili umkhawulokudonsa weyangaphambilini.

La mabhasi asebenzisa izindlela zokuxhumana ezahlukene.Lena “imithetho” elandelwa uhlelo lokusebenza kanye ne-SSD ukuze kuqondanwe:

• I-AHCI (I-Advanced Host Controller Interface): yenzelwe ama-hard drive enziwe ngomshini axhunywe nge-SATA. Ayiphumelelanga lapho kufika ama-SSD ngenxa yemigqa yawo yemiyalo elinganiselwe.
• I-NVMe (Non-Volatile Memory Express): yenzelwe ngqo amadrayivu e-SSD anamuhla, aklanyelwe ukusizakala ngokufana kanye nokufinyelela okusheshayo kwememori ye-flash nge-PCIe.

Inhlanganisela yakudala yama-SSD okuqala yayiyi-SATA + AHCIAma-SATA SSD, asevele emele intuthuko enkulu phambili uma kuqhathaniswa nama-HDD, anomkhawulo ocacile wokusebenza. Ngakho-ke, noma ngabe uthenga i-SATA SSD yakamuva emakethe, isivinini esiphezulu sangempela singama-550 MB/s: sinqunyelwe yi-interface ye-SATA III.

Ngakolunye uhlangothi, i-NVMe yaklanywa kusukela phansi ukuze isebenze nge-PCIe futhi inememori ye-flashLokhu kuvumela imigqa eminingi yemiyalo, ukubambezeleka okuphansi, kanye nokukhula kwesivinini i-SATA engenakukwazi ukukufanisa. Yingakho ama-NVMe SSD exhuma nge-PCIe (ngokuvamile ngefomethi ye-M.2) hhayi i-SATA.

Iyini ngempela i-NVMe SSD?

Uma sikhuluma “ngediski ye-NVMe” noma “i-NVMe SSD”, sikhuluma nge-SSD esebenzisa iphrothokholi ye-NVMe ngaphezu kwesixhumi esibonakalayo se-PCIe.Ngamanye amazwi, kuseyidrayivu yesimo esiqinile esekelwe kumemori ye-flash, kodwa ayixhumi nge-port "endala" ye-SATA, kodwa ixhumeka ngqo ebhasini le-PCI Express lebhodi lomama.

Empeleni, lokhu kusho ukuthi i-NVMe SSD inendlela eqondile kakhulu eya ku-CPU kanye ne-RAM.ngezingqimba ezimbalwa eziphakathi nendawo ezidala izithiyo. Ngaphezu kwalokho, i-NVMe ingaphatha amashumi ezinkulungwane zemigqa yemiyalo ngesikhathi esifanayo, uma kuqhathaniswa nomugqa owodwa we-AHCI, okwandisa kakhulu imisebenzi yokufaka/yokukhipha ngomzuzwana (i-IOPS).

Amadrayivu e-NVMe wabathengi bamanje avame ukuza ngefomethi ye-M.2Nakuba kukhona namamodeli afomethi yamakhadi e-PCIe. Lawa mayunithi afakwe ezixhumini ze-M.2 ezisebenza kumodi ye-PCIe x2 noma x4 futhi, kumabhodi e-motherboard anamuhla, kungaba yi-PCIe 3.0, 4.0, noma ngisho ne-5.0.

Ngezinombolo, i-NVMe SSD ephakathi nendawo inganikeza isivinini esisuka ku-2.000-3.500 MB/s ku-PCIe 3.0 Kufika ku-7.000-8.000 MB/s ku-PCIe 4.0 kanye nangaphezu kuka-10.000-14.000 MB/s ku-PCIe 5.0, kuye ngokuthi imodeli kanye nomthamo wayo. Amanye amamodeli aphezulu afinyelela cishe ku-13.000-14.000 MB/s ngesivinini sokufunda esilandelanayo.

Konke lokhu kwenza i-NVMe ibe yisinqumo esifanele ezindaweni lapho ukufinyelela idatha kukhulu futhi kuhlale njalo.: Ukuhlela ividiyo ye-4K/8K, ukulayisha ukwakheka okuyinkimbinkimbi emidlalweni yevidiyo yesizukulwane esilandelayo, izindawo ze-virtualization, izizindalwazi, noma izinhlelo zokusebenza zokuhlaziya okujulile.

I-SSD vs NVMe: umehluko wezobuchwepheshe kanye nefomethi

Ukuqhathanisa okuvamile emhlabeni wangempela kuphakathi kwe-SATA3 SSD ne-NVMe M.2 SSDNgoba womabili angama-SSD, kodwa axhumana futhi aziphatha ngendlela ehlukile. Ake sibheke umehluko oyinhloko iphuzu ngephuzu.

Isixhumanisi sokuxhumana kanye nemikhawulo yesivinini

Ama-SATA SSD asebenzisa isikhombimsebenzisi se-SATA III esinomkhawulo ophezulu we-theoretical ongu-6 Gb/sLokhu kusho ukuthi cishe isivinini esilandelanayo esingu-550-600 MB/s. Lo mkhawulo ubekwa yibhasi, hhayi i-memory chip: noma ngabe i-SSD iyisimanje kakhulu, ayikwazi ukudlula lo mkhawulo.

Ngakolunye uhlangothi, ama-NVMe SSD axhuma nge-PCIe, futhi lapho uphahla luphakeme kakhulu.Njengesiqondiso, lezi kungaba yizivinini eziphakeme kakhulu zethiyori ngohlobo ngalunye lweyunithi:

• I-SSD ene-interface ye-SATA III: kufika ku-~600 MB/s.
• I-SSD M.2 PCIe 3.0 (NVMe): kufika ku-~4.000 MB/s.
• I-SSD M.2 PCIe 4.0 (NVMe): kufika ku-~8.000 MB/s.
• I-SSD M.2 PCIe 5.0 (NVMe): kufika ku-~16.000 MB/s.

Empeleni, izibalo zangempela zivame ukuba ziphansi kancane kunezo ezicatshangelwayo.Futhi ukufunda cishe njalo kushesha kancane kunokubhala. Kodwa noma kunjalo, umehluko phakathi kuka-550 MB/s we-SATA kanye no-3.500-7.000 MB/s we-NVMe mkhulu kakhulu ephepheni.

Ukubambezeleka, i-IOPS, kanye nokuhambisana

Ngaphandle kwesivinini sayo "esiluhlaza" ku-MB/s, i-NVMe ivelele ngokubambezeleka kwayo okuphansi kakhulu kanye nekhono layo lokusingatha imisebenzi eminingi ngesikhathi esisodwa.Nakuba i-AHCI iklanyelwe ukusingatha ulayini owodwa wemiyalo efinyelela ku-32, i-NVMe ingasebenza ngemigqa efinyelela ku-64.000 kanye nemiyalo engu-64.000 ngolayini.

Lokhu kuholela enanini eliphezulu kakhulu le-IOPS (imisebenzi ngomzuzwana).Lapho i-SATA SSD enhle ingafinyelela cishe ama-IOPS ayi-100.000, idrayivu yesimanje ye-NVMe ingadlula kalula ama-IOPS ayisigidi ngokufundwa okungahleliwe. Lesi yisici esibalulekile kumaseva, izizindalwazi, noma umthwalo womsebenzi onezifinyezo eziningi ezincane zediski.

Ekusetshenzisweni kwansuku zonke kwe-PC yasekhaya, lokhu kubambezeleka okuphansi kubonakala empendulweni yesistimu eshesha kakhulu.Amafasitela avulwa ngokushesha, ukufakwa kuyashesha, futhi umuzwa "wokuxinwa kwethrafikhi" uyancipha uma kunemisebenzi eminingi eyenzekayo ngesikhathi esisodwa.

Ifomethi ebonakalayo kanye nokufakwa

Ama-SATA SSD avame ukuza ngesimo se-2,5” esine-casing yensimbi noma yepulasitikiUkuze uzifake, udinga i-drive bay, ikhebula ledatha le-SATA, kanye nesixhumi samandla esivela kugesi. Lokhu kulungiselelwa kuhambisana kakhulu cishe nanoma iyiphi i-PC yeminyaka engu-15-20 edlule.

Ama-NVMe M.2 SSD afakwe ngqo ebhodini lomama. Basebenzisa isixhumi se-M.2 esikhethekile. Abadingi idatha noma izintambo zikagesi, njengoba konke kudluliswa ngesokhethi uqobo. Lokhu kunciphisa izintambo zangaphakathi futhi kuvumela abakhiqizi bama-laptop ukuthi bakhe amadivayisi amancane kakhulu.

Ukufaka idrayivu ye-M.2 NVMe kulula kakhulu ngokomzimba.Idrayivu ifakwa embotsheni ye-M.2 nge-engeli encane, bese isixhumi sifakwa ngaphakathi ukuze siyivikele. Kubalulekile ukuhlola ibhukwana lebhodi lomama kusengaphambili ukuze ubone ukuthi leyo mbotshana iyayisekela yini i-PCIe/NVMe, i-SATA, noma kokubili.

I-Temperatura de funcionamiento

Elinye iphuzu lapho zihluka khona izinga lokushisaAma-SATA SSD angu-2,5" akhiqiza ukushisa okuncane, ngokwengxenye ngoba isikhombimsebenzisi sinciphisa ukusebenza kwawo futhi ngokwengxenye ngoba i-casing ngokwayo iyasiza ekukuqedeni. Akuvamile ukuba nezinkinga zokushisa.

Ama-NVMe SSD, ikakhulukazi ama-PCIe 4.0 kanye nama-5.0 drive asebenza kahle kakhulu, angaba shushu kakhulu.Uma usebenza ngesivinini esikhulu kakhulu, isilawuli kanye nememori kukhiqiza inani elikhulu lokushisa, okuthi uma kungaphathwa kahle, kungabangela ukugoba kokushisa (ukunciphisa ukusebenza okuzenzakalelayo ukuvikela iyunithi).

Ngenxa yalesi sizathu, amabhodi amaningi esimanje afaka ama-heatsink ezindawo ze-M.2.Futhi ama-NVMe SSD amaningi aphakathi kuya phezulu asevele eza ne-heatsink yawo engasebenzi. Endabeni ye-PCIe 5.0, uzobona nezixazululo ezinamafeni amancane ukuze kulawulwe amazinga okushisa.

Ezinhlelweni ezinomoya ophansi noma ezakhiwe kancane kakhulu, i-SATA SSD ingaba nozinzo oluthe xaxa. uma kungacaci ukuthi izimo zokushisa zizoba zinhle kwi-NVMe esezingeni eliphezulu.

Intengo nge-GB ngayinye kanye nenani lemali

Ngokwesiko, ama-SATA SSD abeshibhile kune-NVMe SSD., ikakhulukazi ezindaweni ezinkulu, okuzenze zakhanga kakhulu kulabo abafuna indawo enkulu yokugcina izinto ngentengo efanelekile.

Njengamanje, umehluko phakathi kwe-SATA3 SSD ne-1TB NVMe SSD unciphe kakhulu.Ezimweni eziningi, i-NVMe ibiza ngaphezu kuka-10-20% kuphela kunokulingana kwayo ne-SATA. Kuye ngamadili, lowo mehluko ungaba ama-euro ambalwa nje.

Kusezingeni eliphezulu kakhulu, ikakhulukazi kuma-PCIe 4.0 kanye nama-drive angu-5.0 anomthamo ophezulu (2-4 TB)Yebo, kukhona ukwenyuka kwentengo okuphawulekayo; izindleko nge-TB ngayinye zisalokhu ziphezulu kuma-drive e-NVMe ashesha kakhulu. Ngaphezu kwalokho, amamodeli anomthamo ophezulu avame ukufeza isivinini esihle kakhulu.

Uma unesabelomali esincane futhi udinga indawo yokugcina eningi, i-SATA SSD iseyindlela enhle kakhulu.Kodwa uma umehluko wentengo ngedrayivu ye-NVMe ungabalulekile futhi ibhodi lakho lomama liyahambisana, ukushintshela ku-NVMe ngokuvamile kuyakufanelekela.

Umehluko ekusetshenzisweni kwangempela: ukuqala, ukudlala imidlalo, ukukopisha, kanye nokwenza imisebenzi eminingi ngesikhathi esisodwa

Ephepheni, umehluko wesivinini phakathi kwe-SATA ne-NVMe mkhulu kakhuluKodwa umbuzo ovamile ukuthi lokhu kuphawuleka kangakanani ekusetshenzisweni kwansuku zonke. Akukona nje kuphela ngezilinganiso: okubalulekile yilokho obhekana nakho lapho usebenzisa idivayisi.

Ukuqalisa uhlelo lokusebenza

Ukuthuthukisa kusuka ku-HDD kuya kunoma iyiphi i-SSD (SATA noma i-NVMe) kuyisinyathelo esikhulu.Isikhathi sokuqalisa singancipha kusukela ngaphezu komzuzu kuya cishe kumasekhondi ayi-10-20, kuye ngekhompyutha. Kulesi simo, umehluko omkhulu umane "ube ne-SSD," hhayi kakhulu ukuthi yi-SATA noma i-NVMe.

Phakathi kwe-SATA SSD ne-NVMe SSD, umehluko wesikhathi sokuqalisa i-Windows uvame ukuba yimizuzwana embalwa nje.Ezivivinyweni ezithile, kubonwe ukuthi idrayivu ye-NVMe ingaqalisa uhlelo ngokushesha ngemizuzwana engu-8 kunedrayivu ye-SATA, kodwa lokhu akuseyona inguquko enkulu njengokushiya i-HDD.

Ukulayisha imidlalo kanye nesipiliyoni sokudlala imidlalo

Uma kukhulunywa ngokudlala, impikiswano ifana kakhuluI-HDD uma iqhathaniswa ne-SSD (SATA noma i-NVMe) yenza umehluko ocacile ezikhathini zokulayisha kanye nokushelela lapho kulayishwa ukwakheka namamephu.

Uma kuqhathaniswa ama-SATA vs ama-NVMe SSD emidlalweni, umehluko wezikhathi zokulayisha uvame ukuba mncane.Emidlalweni eminingi, i-NVMe isheshisa ukulayisha ngomzuzwana owodwa noma emibili uma kuqhathaniswa ne-SATA, into ozoyibona kuphela uma uyibeka ngesikhathi.

Umehluko ubonakala kakhulu emidlalweni evulekile edinga kakhulu kanye nezihloko zesizukulwane esilandelayo ezilungiselelwe i-NVMe.njengalezo ezenzelwe ama-consoles amanje (PS5, Xbox Series X|S) asebenzisa ama-NVMe SSD. Kulezi zimo, izikhathi zokulayisha phakathi kwezindawo noma ukulayisha idatha okuguquguqukayo kungazuza kakhulu ku-bandwidth eyandisiwe.

Noma kunjalo, kubadlali abaningi, i-SATA SSD enhle kakade inikeza ulwazi olwanelisayo kakhulu.Abasebenzisi abaningi bakhetha idrayivu ye-NVMe yesistimu yabo eyinhloko nemidlalo, kanye ne-SATA SSD noma i-HDD enkulu yelabhulali yabo enkulu yemidlalo.

Ukukopisha amafayela nokusebenza ngamasethi edatha amakhulu

Uma ukopisha amafayela amakhulu, umehluko phakathi kwe-SATA ne-NVMe ubonakala kakhulu.Isibonelo, ukuhambisa ifayela elilodwa elingu-30-50 GB kusuka kwenye idrayivu esheshayo kungathatha isikhathi esingaphansi ngokuphindwe kathathu kudrayivu ye-NVMe kunakudrayivu ye-SATA.

Uma usebenza ngokuhlela ividiyo, ukudweba, ukuthwebula izithombe ezinesinqumo esiphezulu, noma amaphrojekthi amakhulu (isibonelo, imishini ebonakalayo, izizindalwazi zendawo noma amaphrojekthi okuthuthukisa anzima), i-NVMe inikeza inzuzo ecacile: isikhathi esincane sokulinda ukuthi lawo mafayela akopishwe noma alayishwe.

Ngakolunye uhlangothi, uma iningi lamafayela akho lincane (amadokhumenti, izithombe ngazinye, ama-PDF, njll.)Umehluko, yize ukhona, awumangalisi njengasezimweni zamafayela amakhulu aqhubekayo.

Ukwenza imisebenzi eminingi kanye nomuzwa wokuguquguquka

Ezimweni eziningi, idrayivu ye-NVMe izwakala isabela kangcono kunedrayivu ye-SATA., ngenxa yokubambezeleka kwayo okuphansi kanye nekhono layo lokusingatha izicelo eziningi ngasikhathi sinye ngaphandle kokuzikhandla.

Uma uvame ukuba nezinhlelo eziningana ezidinga izinsiza eziningi ezivuliwe ngesikhathi esisodwa (abahleli, imidlalo, isiphequluli esinamathebhu amaningi, imishini ebonakalayo, njll.)Uhlelo lwe-NVMe luvame ukungasheshi uma konke kubhekene nezinkinga zokusebenza ngasikhathi sinye. Akuyona imilingo, kodwa kukhona ukwanda okuphawulekayo kokushelela.

Ukusetshenziswa okulula kakhulu (izinhlelo zokusebenza zehhovisi, ukuphequlula, ukusakaza)Umehluko phakathi kwe-SATA SSD ne-NVMe SSD ucashile impela; nganoma iyiphi yazo uzobona ukuthi ikhompyutha yakho ishesha kakhulu uma uvela kwi-HDD.

Izinkinga ezingaba khona kanye nokungalungi kwama-NVMe SSD

Akuzona zonke izinzuzo; i-NVMe nayo inezinkinga zayo kanye nemikhawulo yayo. okubalulekile ukukukhumbula ngaphambi kokuyithenga.

Izidingo zokuphathwa kwezinga lokushisa kanye nokusatshalaliswa

Njengoba sesishilo kakade, amadrayivu e-NVMe asebenza kahle kakhulu akhiqiza ukushisa okuningi.Uma idrayivu idlula amazinga okushisa athile, inciphisa ngokuzenzakalelayo ijubane layo ukuze izivikele, okungathinta ukusebenza kwayo ngesikhathi somsebenzi omude (amakhophi amakhulu, ukuhumusha, njll.).

Ama-drive e-PCIe 4.0, ikakhulukazi ama-drive e-PCIe 5.0, azwela kakhulu kulesi sici.Akuvamile ukubabona benama-heatsink amakhulu, kanti kwamanye amamodeli, namafeni amancane ukusiza ukugcina izinga lokushisa lingaphakathi kwemingcele ephephile.

Ngokuphambene nalokho, ama-SATA SSD angu-2,5” awavamile ukuba nezinkinga zokushisa ngokweqile.Lokhu kungenxa yemikhawulo yesivinini sayo kanye nokuthi ikesi ngokwalo kanye nokuhamba komoya ngokuvamile kwanele.

Ukuhambisana kwe-Motherboard

Ukuze ufake idrayivu ye-NVMe, ibhodi lakho lomama lidinga okungenani ukuba nesokhethi elilodwa le-M.2 elinokusekelwa kwe-PCIe/NVMe.Ama-motherboard amaningi nama-laptops eminyaka engu-5-7 edlule ayawafaka, kodwa akuzona zonke izixhumi ze-M.2 ezifanayo.

Amanye amabhodi omama anezikhala ze-M.2 ezisekela kuphela amadrayivu e-M.2 SATALokhu kusho ukuthi, nakuba ingaba nesimo esifanayo somzimba, idrayivu izosebenza kusetshenziswa i-SATA futhi ngeke isebenzise i-NVMe. Ezicacisweni, kufanele ubheke ichweba elisekela i-"PCIe x4" noma i-"NVMe".

Ezinhlelweni ezindala ezingenayo i-M.2, idrayivu ye-NVMe ingasetshenziswa ngama-adapter e-PCIe.Kodwa-ke, udinga ukuqinisekisa ukuhambisana kwe-BIOS ukuze uqalise uhlelo kusukela kuleyo drive, futhi akuhlali kufakwa futhi kudlalwe njenge-SATA SSD; uma kunjalo, kungadingeka buyekeza i-BIOS Ngokuqaphela.

Ukulinganiswa kwentengo kanye nomthamo

Njengomthetho ojwayelekile, izindleko nge-TB ngayinye zihlala ziphezulu kuma-drive e-NVMe asheshayo kunama-SATA SSDikakhulukazi ezindaweni ezinomthamo ophezulu njenge-2 TB noma i-4 TB. Kuvamile ukuthi idrayivu ye-1 TB NVMe esheshayo ibize ngendlela efanayo, noma ngisho nangaphezu kwalokho, idrayivu ye-2 TB SATA.

Ngaphezu kwalokho, amamodeli amaningi e-NVMe anikeza ukusebenza kwawo okuphezulu kakhulu ezinguqulweni ezinomthamo ophezulu.Isibonelo, imodeli ye-1 TB ingaba ne-7.000 MB/s, kuyilapho izinguqulo ze-2 TB noma ze-4 TB zandisa isivinini ngisho nangokwengeziwe ngenxa yama-chip amaningi ahambisanayo.

Uma ufuna nje indawo yokugcina idatha noma imidlalo eningi esheshayo nengabiziAma-SATA SSD ahlala eyinketho enhle kakhulu futhi elinganiselayo ngezindleko.

I-NVMe, i-AI, idatha enkulu, kanye nezindawo zobungcweti

Ezweni lobuchwepheshe nelebhizinisi, i-NVMe ibilokhu iyingxenye ebalulekile ekuthuthukisweni kwekhompyutha yesimanje.I-bandwidth yayo ephezulu, ukubambezeleka okuphansi kakhulu, kanye nomthamo omkhulu wokulinganisa kuye kwenza kwaba yindinganiso yangempela ezikhungweni zedatha zanamuhla.

Izinhlelo zokusebenza ezifana nobuhlakani bokwenziwa (AI), ukufunda komshini (ML), noma ukuhlaziywa kwedatha enkulu Kudingeka bathuthe idatha eningi kakhulu njalo. Kulezi zimo, ukulinganiselwa kwe-SATA kanye nephrothokholi endala ye-SCSI kwakuyisithiyo esikhulu kakhulu.

Ngokusebenzisa i-NVMe ngaphezu kwe-PCIe, amaseva angasebenza nama-drive amaningi ngesikhathi esifanayo.Lokhu kunciphisa umthelela wengqalasizinda, kunciphisa ukusetshenziswa kwamandla ngokusebenza ngakunye, futhi kunciphisa izithiyo ze-CPU. Yingakho sibona izixazululo ze-NVMe eziningi kakhulu kuma-array esitoreji, izinhlelo ezihlanganisiwe, kanye namapulatifomu amafu.

Okufanele ukhethe esimweni sakho: i-SATA SSD noma i-NVMe

Kuleli qophelo, umbuzo omkhulu uwukuthi: iyiphi inketho engcono kakhulu ye-PC yami ethile? Ayikho impendulo eyodwa, kodwa kunemithetho ecacile kuye ngohlobo lokusetshenziswa kanye nesabelomali.

Kwekhompyutha endala noma esezingeni lokuqala esekela i-SATA kuphelaUkukhetha kulula: i-SATA SSD engu-2,5" izoshintsha umdlalo uma iqhathaniswa ne-HDD. Izikhathi zokuqalisa ezisheshayo, uhlelo oluphendulayo, futhi akukho nkinga ngama-adapter noma izinkinga zokuhambisana eziyinkimbinkimbi.

Kwekhompyutha yesimanje enesikhala se-M.2 PCIe kanye nesabelomali esiphakathi nendawoIndlela enengqondo kakhulu ngokuvamile ukufaka idrayivu ye-NVMe yesistimu yokusebenza kanye nezinhlelo zokusebenza eziyinhloko. Uma udinga isitoreji esengeziwe semidlalo noma idatha, ungangeza i-SATA SSD eyengeziwe noma i-HDD enkulu uma isabelomali sakho sincane.

Uma imishini ihloselwe imidlalo yesimanje, ukuhlela ividiyo, ukuklama kwe-3D, ukusakaza, noma umsebenzi wobungcwetiI-NVMe SSD, okungcono kakhulu i-PCIe 4.0, iyaziswa kakhulu ngezikhathi zokulayisha, ukuphatha amaphrojekthi amakhulu, kanye nokusebenza kahle komsebenzi.

Ku-server, i-virtualization, noma izindawo ze-databaseI-NVMe ibaluleke kakhulu uma kudingeka ukusebenza okuphezulu. I-SATA ifakwa kwisitoreji sesibili noma kuma-backups lapho isivinini singabalulekile khona.

Kunoma ikuphi, igxathu elibalulekile ukuhamba kusuka ku-HDD kuya ku-SSDKukhona umehluko phakathi kwe-SATA SSD ne-NVMe SSD, kodwa iphakathi kakhulu ekusetshenzisweni kwansuku zonke kunomehluko uma kuqhathaniswa ne-hard drive yomshini, ngakho-ke kunengqondo ukucabangela isilinganiso sentengo/ukusebenza kanye nezidingo zakho zangempela.

Ekugcineni, kubalulekile ukuqonda ukuthi i-SATA SSD kanye ne-NVMe SSD ziyizindlela ezimbili ezahlukene zokusebenzisa i-flash memory.Ngezixhumi ezahlukene, amaphrothokholi, kanye namazinga okusebenza, ikuvumela ukuthi ukhethe ngokuhlakanipha: uma okubaluleke kakhulu kuwe ukukhulisa isivinini futhi ibhodi lakho le-motherboard likuvumela, i-NVMe iyisinqumo esiphumelelayo; uma ufuna ibhalansi ephelele phakathi kwentengo, ukuhambisana, kanye nesipiliyoni esihle cishe kunoma iyiphi ikhompyutha, i-SATA SSD isalokhu ingumsizi omuhle kakhulu.
