Uma ucabanga ngokuthuthukisa ikhompyutha yakho noma ukusetha iseva esheshayo, khetha uhlobo olufanele lwesitoreji Kubaluleke kakhulu njenge-CPU noma i-RAM uqobo. Sekuyiminyaka eminingi, ama-SATA SSD abe ngcono kakhulu kune-hard drive yomshini, kodwa lokho kuguquka akuphumelelanga ngokufika komdlali omusha: Isitoreji se-NVMe.

Lobu buchwepheshe abuthuthukisi isivinini kancane nje: Kushintsha ngokuphelele indlela uhlelo olufinyelela ngayo idathaIzikhathi zokuqalisa ezisheshayo, ukulayisha imidlalo okusheshayo, izizindalwazi ezisheshayo, kanye namaseva angaphatha ithrafikhi eningi kakhulu ngehadiwe efanayo. Ake sibheke kabanzi ukuthi iyini i-NVMe, ukuthi isebenza kanjani, ihluke kanjani kwi-SATA kanye ne-SAS, nokuthi yiziphi izinzuzo zangempela ezinikezayo kwi-PC yasekhaya noma endaweni yobungcweti.

Iyini ngempela isitoreji se-NVMe?

I-NVMe (Non-Volatile Memory Express) Kuyinqubo yokuxhumana eyenzelwe kusukela ekuqaleni ukuze isebenze nayo izinkumbulo zesimanje ezingaguquki, njenge-NAND Flash, sisebenzisa izindlela zokuxhumanisa I-PCI Express (PCIe)Ngokungafani ne-SATA noma i-SAS, ezazenzelwe ekuqaleni ama-hard drive enziwe ngomshini, i-NVMe yadalwa ngomqondo ocacile: ukukhulisa isivinini, ukufana, kanye nokubambezeleka okuphansi kwama-SSD.

Uma i-NVMe SSD ixhunywe ohlelweni, Ikwenza ngqo ku- ibhasi le-PCIe lebhodi lomamangaphandle kwesidingo sokudlula kubalawuli abaphakathi njengaku-AHCI. Lo mzila oqondile uyivumela ukuthi ixhumane ngesivinini esiphezulu ne-CPU kanye ne-RAM, igwema izithiyo ezivamile ze-interface zangaphambilini futhi inciphise isikhathi sokuphendula sibe amasekhondi amancane ambalwa.

Esinye isici esibalulekile se-NVMe yikhono layo lokuphatha imigqa yokufaka/yokukhipha eminingi (I/O)Indinganiso isekela imigqa efinyelela ku-64.000, futhi umugqa ngamunye ungaphatha imiyalo efinyelela ku-64.000 ngesikhathi esisodwa. Lokhu kuvumela ukucubungula inani elikhulu lezicelo ngesikhathi esisodwa, kusetshenziswa ngokugcwele amaprosesa amanje e-multi-core kuma-PC nakumaseva.

Ngakolunye uhlangothi, izinqubo zendabuko ezifana ne-AHCI ezisetshenziswa ku-SATA zivumela kuphela umugqa onemiyalo engu-32Lokhu kuholela ezikhathini zokulinda, ukubambezeleka okuphezulu, kanye nokusetshenziswa kabi kwamandla ekhompyutha lapho kunemisebenzi eminingi yokufunda nokubhala ngesikhathi esisodwa, into evame kakhulu ezinhlelweni zokusebenza zanamuhla, kudathabheyisi, noma ku-virtualization.

Ukuthuthukiswa kwe-NVMe kwenzeke phakathi I-2008 ne-2011 Ngenhloso ecacile: ukufaka esikhundleni se-SATA kanye ne-SAS ezimweni lapho isivinini kanye nokusebenza kahle kubaluleke kakhulu. Izinzuzo zayo ziye zabonakala kakhulu kangangokuthi indinganiso isibe uphawu lokugcina ukusebenza okuphezulu, kokubili kumakhompyutha asekhaya athuthukile kanye nasezindaweni zesikhungo sedatha.

Ubudlelwano phakathi kwe-NVMe kanye ne-PCI Express interface

Enye yezinzuzo ezinkulu ze-NVMe ngaphezu kobuchwepheshe bangaphambilini ukuthi Ithembela ngqo emizileni ye-PCIe yohlelo. I-PCIe inikeza umkhawulokudonsa omkhulu Ngaphezu kwalokho, ivumela idivayisi ukuthi ixhumane ne-RAM ngaphandle kokudinga ukudlula ezingqimbeni ezengeziwe njenge-IOMMU ezimweni eziningi, okunciphisa kakhulu ukubambezeleka kanye nokusetshenziswa kwezinsizakusebenza zeprosesa.

Lokhu kuxhumana okuqondile kwenza kube nokwenzeka nge-NVMe SSD ukushintshanisa idatha ngokushesha kakhulu nge-RAM kanye ne-CPULokhu kubalulekile lapho kuphathwa amafayela amakhulu noma ukusakazwa kwedatha okuqhubekayo. Isibonelo, kubaluleke kakhulu emisebenzini efana nokuthi Ukuhlela ividiyo ye-4K noma ye-8KUkuboniswa kokuthungwa kwe-3D emidlalweni yevidiyo, ukumodela kwe-3D kochwepheshe, noma ukuhlaziywa kwenqwaba yolwazi.

Ezinsukwini zokuqala zama-SSD axhunywe kwi-PCIe, kwakudingeka ama-firmware aqondile kakhulu kanye nokuntuleka kokuhlelwa kwesimo kwasho ukuthi amandla aphelele ebhasi ayengasetshenziswa. Ukuze kuxazululwe le nkinga, kwasungulwa iphrothokholi ye-NVMe, echaza indlela uhlelo lokusebenza kanye ne-SSD ezixhumana ngayo ngendlela efanayo, ephumelelayo, neyandisiwe.

Ngenxa yale phrothokholi, uhlelo oluvamile lwemvelo seluvele lusungulwe phakathi kwabakhiqizi. Ama-drive e-NVMe asephenduke uhlobo oluvelele lwe-SSD kuma-PC anamuhla asezingeni eliphakathi kanye nasezingeni eliphezulu, kanye nakumaseva. Ngaphezu kwalokho, i-NVMe yaklanywa ukuze iguquke ngokuhamba kwesikhathi, okuvumela izibuyekezo kanye nokwandiswa kwamakhono ayo ngezinguqulo ezintsha ze-firmware kanye nemininingwane.

Esinye isici esibalulekile ukuthi i-NVMe ayikhawulelwe ku-PCIe "yasendaweni": I-NVMe phezu kwezindwangu (NVMe-oF) ikhonaLokhu kuvumela iphrothokholi ukuthi inwetshwe ezinhlotsheni ezahlukene zamanethiwekhi, njenge-Ethernet, i-Fibre Channel, noma i-InfiniBand. Lokhu kuvula umnyango wezakhiwo zokugcina inethiwekhi ngokusebenza okufana kakhulu nokwedrayivu yendawo, kodwa ngokuguquguquka kwesistimu esatshalaliswe.

Amafomethi angokoqobo kanye nezinhlobo ze-NVMe drive

Uma sikhuluma nge-NVMe, asibhekiseli nje kuphela kuphrothokholi, kodwa futhi naku- amafomethi ahlukene e-SSD angokomzimba abayisebenzisayo. Evame kakhulu emishinini yabasebenzisi nasezindaweni zobungcweti yilezi ezilandelayo:

Ngakolunye uhlangothi sinama-NVMe SSD ku Ifomethi ye-M.2Lezi zithandwa kakhulu kuma-laptop nakuma-desktop esimanje. Zibunjwe njengomugqa omude (ofana "nephilisi lokuhlafuna i-gum") elixhuma ngqo kubhodi lomama ngaphandle kwezintambo, okonga isikhala futhi kuthuthukise ukuhamba komoya ngaphakathi kwebhokisi le-PC.

Emkhakheni wobungcweti, amayunithi asetshenziswa kakhulu U.2 noma U.3ezifana namadiski angu-2,5 intshi futhi zivumela ukushintshana kwe-hot kumaseva, into ebalulekile emisebenzini yokulungisa kanye nokushintsha okusheshayo ngaphandle kokucima umshini.

Kukhona namakhadi I-PCIe AIC (Ikhadi Lokwengeza)Lokhu kufakwa ngqo kwi-PCIe slot, njengekhadi lehluzo. Le fomethi isetshenziselwa kakhulu isitoreji esisebenza kahle kakhulu noma ukufaka amadrayivu amaningi e-NVMe ekhadini elifanayo kumaseva aphezulu.

Ezinhlelweni zasekhaya, ifomethi ye-M.2 ibekwe ngendlela efanayo ngobubanzi obufanayo obungu-22 mm kodwa obuhlukahlukene ngobude. Ngakho-ke, sithola amayunithi 2230, 2242, 2260, 2280 no-22110lapho izinombolo ezimbili zokuqala zibonisa ububanzi (22 mm) kanti ezilandelayo zikhombisa ubude ngamamilimitha. Ifomethi ebanzi kakhulu namuhla ingu-2280, ekhona kumabhodi amaningi omama nama-laptop.

Ngaphezu kosayizi, kufanele futhi ucabangele Uhlobo lwesixhumi se-M.2Kunezinhlobo ezintathu ngokuyinhloko: i-M-Key, i-B-Key, kanye ne-B+M-Key. Isixhumi se-M-Key sihlotshaniswa namadrayivu e-NVMe asebenzisa imizila ye-PCIe (ngokuvamile i-x4), i-B-Key ihlotshaniswa namadivayisi alinganiselwe kakhulu (isibonelo, i-PCIe x2 noma amamojula athile okuxhumana), kanti i-B+M-Key igcinelwe kakhulu ama-SSD asekelwe ku-SATA anejubane eliphansi kakhulu.

Umehluko phakathi kwama-NVMe nama-SATA SSD (nezinye izinqubo)

Ngolimi lwansuku zonke sivame ukuthi "Ngine-SSD" uma sibhekisela kuyo idrayivu yesimo esiqinile exhunywe nge-SATAIsixhumi esifanayo esisetshenziswa ama-hard drive amadala emishini. Lokho kugxuma sekuvele kubonise ukuthuthuka okukhulu ezikhathini zokulayisha zokuqalisa kanye nohlelo, kodwa isikhombimsebenzisi se-SATA III sinomkhawulo wethiyori ongaba ngu-600 MB/s, osevele uphelelwe amandla ngokuphelele.

Lapho sikhuluma nge I-NVMe SSD Sisakhuluma nge-solid-state drive, kodwa ngoshintsho olukhulu: esikhundleni sokusebenzisa i-SATA port, ixhuma ebhasini le-PCI Express futhi ixhumana isebenzisa iphrothokholi ye-NVMe. Le nhlanganisela ivumela isivinini sama-oda amaningana aphezulu kakhulu kune-SATA SSD yendabuko.

Ngokwemibandela engokoqobo, ngenkathi i-SATA SSD iseduze 500-550 MB/s Ukuze uthole isivinini sokufunda nokubhala esilandelanayo, idrayivu ye-NVMe ku-PCIe 3.0 ingahamba cishe ku-3.500 MB/s. PCIe 4.0 ukunqoba i I-7.000 MB / s futhi ku-PCIe 5.0 sondela ku- I-14.000 MB / sSikhuluma ngokuba ngokushesha izikhathi eziyi-10 kuya kwezingama-20 ezimweni zokudlulisa ezilandelanayo.

Kodwa isivinini se-MB/s asiyona into ebaluleke kakhulu. I-NVMe iphumelela kakhulu ku- IOPS (imisebenzi yokufaka/yokukhipha ngomzuzwana) kanye nokubambezeleka. Ngenxa yemigqa yayo yomyalo ehambisanayo kanye nomklamo wesimanje, i-NVMe SSD ingadlula kalula i-IOPS yezigidi ezimbili futhi isheshe kufike ku-900% kunedrayivu ye-AHCI kweminye imisebenzi.

Uma kuqhathaniswa ne-SAS, esetshenziswa ngokwesiko kumaseva, okunikezwa yi-NVMe ukusebenza okuphezulu kakhulu ngokusetshenziswa kwamandla okuphansi kanye nokusetshenziswa okulula ngokwengeziwe. I-SAS isenendawo yayo, kodwa ngenxa yokugcina i-flash ye-NVMe esebenza kahle kakhulu isizimise njengendinganiso yemboni yangempela.

Ngokuphathelene nolwazi lomsebenzisi, lokhu kuhunyushwa ohlelweni lokusebenza Kuqala ngemizuzwana embalwa.Izinhlelo zokusebenza zivuleka cishe ngokushesha, imidlalo yevidiyo ilayisha amamephu kanye nokuthungwa ngaphandle kwezikrini zokulinda isikhathi eside, futhi imisebenzi enzima ngamafayela amakhulu (ukukopisha, ukususa ukucindezela, ukuhlela) yenziwa ngesikhathi esincane.

I-NVMe isebenza kanjani ukuze ifinyelele isivinini esikhulu kangaka?

Ukuze uqonde ukuthi kungani i-NVMe ishesha kangaka, kufanele ubheke ukuthi iphatha kanjani imigqa yemiyalo yokufaka neyokukhiphaIsikhathi ngasinye lapho uhlelo ludinga ukufunda noma ukubhala idatha, luthumela isicelo esibekwa emgqeni. Nge-NVMe, uhlelo alukhawulelwe emgqeni owodwa omfushane, kodwa lungaba namashumi ezinkulungwane zemigqa, ngamunye unezicelo ezingamashumi ezinkulungwane.

Lesi sakhiwo siyakuvumela Sabalalisa imisebenzi phakathi kwama-core e-CPU ahlukeneLokhu kunciphisa izikhathi zokuvimba nokulinda. Ngenkathi i-core eyodwa icubungula umugqa owodwa, enye ingaphatha omunye ngasikhathi sinye, okuhambisana kahle nokwakheka kwe-multi-core kwama-desktop nama-server processors amanje.

Ngaphakathi kwe-SSD uqobo, ingxenye ebalulekile yi- isilawuli se-flashI-microcontroller esebenzisa iphrothokholi ye-NVMe futhi ihlele ukufinyelela kuma-chip ememori ye-NAND. Lesi silawuli sisebenza ngendlela efanayo nesilawuli se-RAM, kodwa sisebenza nememori engaguquki, siphatha ukuguguleka, ukulungiswa kwamaphutha, kanye nokuhlela idatha yangaphakathi.

Ngenxa yalo mklamo, izigaba ezidinga kakhulu zephrothokholi Le misebenzi idluliselwa ngaphakathi kwe-SSD uqobo, ikhulula i-CPU eyinhloko yesistimu emsebenzini omningi. Umphumela uba imijikelezo ephansi yeprosesa ngokusebenza kwe-I/O, okuthinta kokubili ukusebenza okuphelele kanye nokusebenza kahle kwamandla.

Ngaphezu kwalokho, ngokungathwali ifa lama-hard drive emishini, i-NVMe iqeda ukubambezeleka okuhlobene nokulinda kwemishini, ukuhlela kabusha imikhakha, kanye neminye imikhawulo yomlando. Konke kuklanyelwe ukwenza ukufinyelela kube ngqo ngangokunokwenzeka futhi kuzuze ngokugcwele izici zememori yesimanje ye-flash.

Izinzuzo eziyinhloko zesitoreji se-NVMe

Inzuzo yokuqala enkulu ye-NVMe ukuthi isivuno esikhuluUma kuqhathaniswa ne-SATA III engaba ngu-0,6 GB/s, idrayivu ye-NVMe ku-PCIe x4 ingafinyelela ku-4 GB/s ngezizukulwane zangaphambilini ze-PCIe, ngaphezu kuka-7 GB/s nge-PCIe 4.0, futhi ifinyelela ku-14 GB/s nge-PCIe 5.0. Lezi zinombolo zimelela igxathu elikhulu kunoma yimuphi umsebenzi lapho isitoreji singumthwalo wemfanelo.

Enye inzuzo yi ukubambezeleka okuphansi kakhuluNgokuba nokuxhumana okuqondile ne-CPU kanye ne-RAM nokusebenzisa imigqa ehambisanayo, isikhathi sokuphendula sincishiswa kakhulu. Lokhu kubalulekile ezinhlelweni zokusebenza lapho i-millisecond ngayinye ibalwa khona, njengezizindalwazi ezinabantu abaningi, izinsizakalo zewebhu ezinezinkulungwane zabasebenzisi abakanye, ukuhweba, ukuhlaziywa kwedatha ngesikhathi sangempela, noma izindawo zobuhlakani bokwenziwa.

I-NVMe nayo ivelele nge- ukusebenza kahle kwamandlaUkuze kwenziwe imisebenzi efanayo ne-SATA SSD noma uhlelo olusekelwe ku-SCSI, kudinga imisebenzi embalwa yezinga le-CPU kanye namadivayisi ambalwa angokoqobo ukuze kufezwe ukusebenza okufanayo. Esikhungweni sedatha, lokhu kusho ukusetshenziswa kwamandla okuphansi, ukukhiqizwa kokushisa okuncane, kanye nezidingo zokupholisa ezincishisiwe.

Ezingeni elingokoqobo, ama-NVMe SSD, ikakhulukazi ngefomethi ye-M.2, thatha isikhala esincane kakhuluLokhu kuvumele abakhiqizi bebhodi lomama ukuthi bangeze izikhala eziningi ze-M.2 ngqo ku-PCB futhi banciphise ukuxinana kwezintambo ze-SATA ngaphakathi kwekesi. Kuma-laptop, usayizi omncane ulungele izinhlelo ezincane nezilula ezinezindawo zokugcina eziningi.

Elinye iphuzu elivunayo yi- ukukhubazekaNgenxa ye-NVMe-oF, inqubo efanayo ingasetshenziswa kumanethiwekhi afana ne-Ethernet noma i-Fibre Channel, yandisa ukusebenza kwe-NVMe ngale kweshasi yeseva uqobo. Lokhu kuvula umnyango wezixazululo zesitoreji esabiwe esine-latency ephansi kakhulu kanye nokusebenza okwakutholakala kuphela ngezinhlelo ezikhethekile kakhulu.

Ekugcineni, i-NVMe yaklanywa njenge indinganiso yesikhathi esideImininingwane yayo isekela izibuyekezo ze-firmware kanye nezici ezintsha ngaphandle kokudinga ushintsho oluphelele lwesakhiwo, okuvumela abakhiqizi ukuthi bathuthukise amadrayivu abo ngokuhamba kwesikhathi futhi bafake ukuthuthukiswa okufana nezikhala zamagama ezibekwe endaweni (i-ZNS), izici zokuphepha ezithuthukisiwe, noma ukwesekwa kokuqalisa okukude.

Okubi kanye nokucatshangelwa ngaphambi kokukhetha i-NVMe

Akuzona zonke izinzuzo, futhi ezinye izinto kufanele zicatshangelwe. ukulinganiselwa kanye nezidingo Ngaphambi kokuphuthuma ukuyothenga i-NVMe SSD, into yokuqala okufanele uyicabangele ukuhambisana: akwanele ukuthi ibhodi lakho lomama libe ne- M.2 slotKuyadingeka ukuthi le slot isekele ngqo i-PCIe/NVMe hhayi i-SATA kuphela.

Ukuhlola lokhu, indlela ethembeke kakhulu yile hlola imodeli yebhodi lomama eqondile Ungathola lolu lwazi encwadini yemiyalelo, kuwebhusayithi yomkhiqizi, noma usebenzisa amathuluzi afana ne-dxdiag nezinye izinsiza zokuxilonga. Amabhodi amaningi amadala afaka izikhala ze-M.2 zamadrayivu e-SATA kuphela, futhi kuleso simo, i-NVMe SSD ngeke isebenze noma ngeke ibonwe yi-BIOS/UEFI.

Sidinga futhi ukubheka Inguqulo ye-PCI Express isekelwa yi-motherboard kanye ne-processor. Uma ikhompyutha yakho isekela i-PCIe 3.0 kuphela, ukuthenga i-PCIe 5.0 drive ngeke kukunikeze ukusebenza okungaphezu kwe-PCIe 3.0 noma i-4.0 drive, yize izohambisana ezimweni eziningi ngoba izinguqulo zivame ukuhambisana emuva ezingeni lesignali.
