Namuhla sifuna ukukhuluma ngomunye wemikhiqizo yethu emisha - idrayivu ye-Seagate FireCuda 520 SSD. Kodwa ungajahi ukupheqa ngokuphakelayo ngemicabango “kahle, okunye ukubuyekezwa okutusekayo kwegajethi evela kumkhiqizo” - sizamile yenza ukwaziswa kube usizo futhi kuthakazelise. Ngaphansi kokusikwa, okokuqala ngeke sigxile kudivayisi uqobo, kodwa esibonakalayo sePCIe 4.0 esisebenzisayo. Futhi sizokutshela ukuthi yini ongayilindela kuyo, kungani iyinhle nokuthi ingaba wusizo kubani.
Masikhulume iqiniso: I-PCI Express 4.0 akuyona into entsha. Amadivayisi okuqala anokusekelwa kwawo avele emakethe yabathengi ehlobo eledlule. Siyabonga ngalokhu kufanele sithi ku-AMD: kwakuyinkampani eyakha amapulatifomu okuqala akwazi ukwamukela amadivaysi nge-PCI Express 4.0, futhi yenza amadivaysi anjalo ngokwawo - lawa amakhadi wehluzo asekelwe ku-GPU anezakhiwo ze-RDNA.
Ukwenyuka komkhawulokudonsa kuhlale kunikeza ithemba elikhulu, kodwa njengoba kuvela, amakhadi wevidiyo awazuzi nhlobo ngokushintshela esibonakalayo esisheshayo. Okungenani uma kukhulunywa ngemithwalo yemidlalo. Njengoba kubonisiwe ukuhlola okuningi okuzimele, ngisho namakhadi ashesha kakhulu asekela i-PCI Express 4.0, ikakhulukazi i-Radeon RX 5700 XT, enza okufanayo kokubili lapho usebenzisa isixhumi esibonakalayo esisha nesisheshayo nalapho exhunywe ebhasini lakudala le-PCI Express 3.0.
Kodwa nge-solid-state drives kuyindaba ehluke ngokuphelele. Isivinini sokusebenza sama-NVMe SSD asebenza nge-PCI Express 3.0 (isibonelo, i-Seagate FireCuda 510) ngaphansi kwemithwalo ewumugqa sinqunyelwe ngokucacile umkhawulokudonsa wesixhumi esibonakalayo. Ngakho-ke, ukwandisa imikhawulo yomkhawulokudonsa kumane nje kube nomthelela omuhle emandleni wezinhlelo ezingaphansi zediski yesizukulwane esisha.
Umfanekiso omuhle weqiniso lokuthi awukho umkhawulokudonsa owanele yiqiniso lokuthi ngenkathi sikhuluma ngamadivayisi okuqala asekela i-PCI Express 4.0, i-PCI Special Interest Group (PCI-SIG) isivele ivume ukucaciswa kwe-PCI Express 5.0, okuthathayo. kuyisinyathelo esisodwa esiya ekukhuliseni isivinini sezindawo lapho amaphrosesa esimanje axhumana khona namadivayisi angaphandle. Kepha mayelana nalokhu ngesinye isikhathi, namuhla i-PCI Express 4.0 isohlwini lwe-ajenda.
Yini enhle nge-PCI Express 4.0?
Ukucaciswa kwe-PCIe (i-Peripheral Component Interconnect Express) kulinganisa indlela amakhadi okunweba anjengama-accelerator ezithombe, izilawuli zomsindo, ama-adaptha enethiwekhi, futhi ekugcineni ama-NVMe SSD axhumana nezingxenye eziyisisekelo ezakha inkundla ye-PC. Ukuphakama kwenguqulo ye-PCIe ecacisiwe, kulapho i-output eyinikezayo iphezulu. Ukwengeza, lapho ukhuluma nge-PCIe slots, ngaphezu kwenguqulo ecacisiwe, baphinde bakhulume ngenani lemizila, eqokwe njenge-x1, x2, x4, x8 noma x16. Inombolo enkulu yemigqa iphinde inikeze ukudlula okuningi okuphakeme ngenxa yokunwetshwa kwebhasi futhi imele enye, indlela ebanzi yokuthuthukisa izici zesivinini zesixhumi esibonakalayo. Kodwa uma sikhuluma ngama-NVMe SSDs, le ndlela kunzima ukuyisebenzisa kuwo. Atholakala ku-compact M.2 form factor, ama-PC SSD angasebenzisa imizila emibili noma emine, kuyilapho ukusekelwa kwemizila efika kweyi-16 kukhawulelwe kumakhadi e-PCIe anosayizi ogcwele. Kungalesi sizathu ukwethulwa kwezinguqulo ezintsha zezinga le-PCIe kuthathwa njengomcimbi obalulekile wemakethe ye-SSD yokusebenza.
Zonke izinguqulo zokucaciswa kwe-PCIe ziyahambisana emuva. Amadrayivu aqondiswe ku-PCIe 4.0 nawo angasebenza ezisekelweni ezisekela i-PCIe 3.0 kuphela, futhi amabhodi omama ane-PCIe 4.0 Slots angafaka kalula izingxenye ezisebenza ngokuhambisana nezinga le-PCIe 3.0. Nokho, kuzo zombili izimo, isistimu izosebenza ngesivinini se-PCIe 3.0, inguqulo encane yezinga elisekelwa nhlangothi zombili.
Ukuqamba okusha okufakiwe ku-PCIe 4.0 umkhawulokudonsa ophindwe kabili womugqa owodwa. Kunezinketho ezihlukene zezilinganiso zezinombolo zezinguquko ezenzeke, kodwa uma sikhuluma ngamavelu ethiyori kanye nenani eliphakeme, ukucaciswa kwe-PCIe 4.0 kuthatha isivinini sokudlulisa esiphezulu se-1,97 GB / s emgqeni owodwa ohlangothini ngalunye, kuyilapho ku-PCIe 3.0 isivinini esiphezulu sikhawulelwe ku-0,98 GB/s. Kweminye imithombo ungathola izibalo eziphindwe kabili, kodwa lokhu kungenxa yokuthi zibonisa isivinini sokudluliswa kwedatha kuzo zombili izinkomba.
Njengoba sishilo ngenhla, ukwanda okunjalo kwejubane le-interface ekusebenzeni akusizi kakhulu (noma kunalokho, cishe akunamsebenzi ngokuphelele) kumakhadi wezithombe. Ngasikhathi sinye, amadrayivu e-NVMe asebenza ngemizila emine ye-PCIe akwazi ukumpompa afinyelele ku-7,88 GB/s (okungcono) ebhasini elinemizila emine, elivula ububanzi bokuthuthukiswa kokusebenza.
Ngaphezu kokwanda komkhawulokudonsa, izinga le-PCIe 4.0 liphinde lethule ezinye izinto ezintsha. Isibonelo, iqukethe izici ezintsha zokunciphisa ukusetshenziswa kwamandla, kanye nemisebenzi ebanzi kakhulu yokwenza idivayisi ibonakale. Kodwa isiqondiso esiyinhloko lapho abathuthukisi behamba khona kwakusenyuka ngesivinini, futhi cishe yonke into yenziwa ngokuyinhloko ngenxa yalokho. Isibonelo, inani lokuthuthukiswa kwenguqulo entsha yesixhumi esibonakalayo kuhloswe ngayo ukuthuthukisa ubuqotho bezimpawu nokuthembeka kokudluliselwa kwazo. Ngamanye amazwi, kubathengi abaningi, i-PCIe 4.0 isho umkhawulokudonsa ophezulu futhi akukho okunye.
Kuthiwani ngamapulatifomu asekela i-PCI Express 4.0?
Ngeshwa, naphezu kweqiniso lokuthi ukucaciswa kwe-PCI Express 4.0 uqobo kwavunywa emuva ngo-2017, azikho izinkundla eziningi zangempela emakethe ezisekelayo. Lokhu kusho ukuthi uma ufuna ukusebenzisa i-high-performance solid-state drive yesizukulwane esisha, kuzodingeka ukhathazeke hhayi nje ngokuthola idrayivu enjalo ngokwayo, kodwa futhi ngokukhetha isiteji esingakhulula ngokugcwele amandla ayo.
Iqiniso liwukuthi i-interface entsha ye-PCIe 4.0 kuze kube manje isekelwe kuphela yi-AMD, futhi noma kunjalo kuphela ngezingcezu. Isetshenziswa kwamanye amaphrosesa akhelwe esakhiweni seZen 2, futhi ikakhulukazi, ochungechungeni lwe-desktop ye-Ryzen 3000 kanye nochungechunge lwe-Threadripper 3000 olusebenza kahle kakhulu, kodwa, ngokwesibonelo, hhayi ochungechungeni lweselula lwe-Ryzen 4000. Ngaphezu kwalokho, uma ukusekelwa kwe-PCIe 4.0 kutholakala kunoma iyiphi i-Socket sTR4 -motherboard yesizukulwane sesithathu i-Threadripper, ama-Ryzen 3000 processors azokwazi ukusebenzisana nama-PCIe 4.0 peripherals ngemodi yesivinini esigcwele kuphela kuma-motherboards akhelwe ku-chipset ye-X570, lapho imigqa yesiginali yakhelwe khona. kucatshangelwa izidingo ezengeziwe zokuvikela kanye nokunciphisa umsindo kagesi.
Izindaba ezinhle lapha ukuthi abanikazi be-Ryzen 3000 abangaba khona maduze bazokwazi ukuthola izandla zabo kwelinye ikilasi lamabhodi omama angabizi kakhulu ngokusekelwa kwamakhadi wehluzo we-PCIe 4.0 nokushayela. Zizokwakhiwa ku-chipset entsha ye-B550, okufanele ikhishwe phakathi nezinyanga ezimbalwa ezizayo.
Ngokuqondene namapulatifomu e-Intel, awakasekeli i-PCIe 4.0 nhlobo. Ngaphezu kwalokho, amaphrosesa edeskithophu e-Comet Lake-S azophuma maduze nje, azofika nawo womabili isokhethi entsha ye-LGA 1200 processor kanye namasethi amasha we-logic yochungechunge lwe-4.0, nawo ngeke athole i-PCIe 4.0. Uma sikhuluma ngobuningi bezinhlelo zedeskithophu ze-Intel, ukusekelwa kwalesi sikhombikubona kungase kuvele kuphela ngokukhululwa kwama-Rocket Lake processors, kodwa lokhu kuzokwenzeka ekuqaleni konyaka ozayo. Kepha lesi sikhombimsebenzisi singafika kumasistimu eselula ngaphambili: ezinhlelweni, ukusekelwa kwe-PCIe 4.0 kumenyezelwe abacubungula be-Tiger Lake, isimemezelo esisemthethweni esingenzeka kuleli hlobo. Ngaphezu kwalokho, ngeke kukhishwe ukuthi amadeskithophu e-HEDT asebenza kahle kakhulu azoshintshela ku-PCIe XNUMX nakulo nyaka: lokhu kuzokwenzeka uma i-Intel inquma ukunikeza i-Ice Lake-X kule ngxenye - ama-analogue eseva i-Ice Lake-SP.
Ngenxa yalokho, naphezu kweqiniso lokuthi i-PCIe 4.0 izosabalala esikhathini esimaphakathi, njengamanje abasekeli bama-NVMe SSD asheshayo banezinketho ezimbalwa lapho bekhetha inkundla. Okusobala kakhulu kuzo uhlelo lwe-Socket AM4 olusekelwe ku-Ryzen 3000 processor kanye nebhodi lomama elisekelwe ku-chipset ye-X570.
Zihamba kanjani izinto ngamadrayivu asebenzisa i-PCI Express 4.0?
Uma ubheka uhla lwama-NVMe SSD anokwesekwa kwe-PCIe 4.0 okwethulwa emashalofini esitolo, ungathola umuzwa wokuthi imakethe igcwele izinketho ezihlukahlukene zezixazululo zejubane eliphezulu lesizukulwane esisha. Nokho, eqinisweni lo mbono uyakhohlisa. Naphezu kweqiniso lokuthi ukucaciswa kwe-PCIe 4.0 sekuneminyaka eminingana, abathuthukisi bepulatifomu yehadiwe abakakwazi ukuletha inani elanele lezinye izindlela esigabeni sokukhiqiza ngobuningi.
Isilawuli kuphela abakhiqizi be-SSD abangasisebenzisa manje emikhiqizweni yabo i-Phison PS5016-E16. Ngaphezu kwalokho, empeleni, lesi silawuli asikwazi ukubizwa ngokuthi intuthuko egcwele yesizukulwane esisha. Lesi yisixazululo sesikhashana esisekelwe kwenye, i-chip ye-PS5012-E12 yangaphambili, lapho ibhulokhi elisebenzayo elibhekele ibhasi langaphandle livele lashintshwa.
Kumsebenzisi wokugcina lokhu kusho izinto ezimbili. Okokuqala, wonke amadrayivu e-NVMe emakethe ngokusekelwa kwe-PCIe 4.0 awahlukani kakhulu komunye nomunye, okungenani uma kukhulunywa ngokusebenza. Futhi uma ubona ukuthi isivinini esilinganiselwe esiphezulu simenyezelwa ngokuzumayo ngomkhiqizo othile, lokhu kungenzeka kakhulu ngenxa yobuqili babathengisi, futhi hhayi kunoma yiziphi izinzuzo zangempela, ngoba ekugcineni, imikhiqizo yomibili isebenzisa isilawuli esifanayo. Okwesibili, abashayeli be-PCIe 4.0 banamuhla abakwazi ukuziqhayisa ngokusebenzisa umkhawulokudonsa ogcwele webhasi elisha - isivinini esiphezulu esithenjiswe yi-chip ye-Phison PS5016-E16 sisezingeni lika-5 GB/s ngokufunda ngomugqa kanye no-4,4 GB/s ngamarekhodi.
I-corollary ebalulekile ilandela kulokhu okungenhla: ngokuzayo, ama-NVMe SSD angenza okunye ukusebenza ngaphandle kokuthuthela enguqulweni elandelayo yokucaciswa kwe-PCI Express. Udinga nje ukulinda ukubonakala kwabalawuli abasha abanomongo oklanywe kabusha oguqulelwe kumakhono e-PCIe 4.0. Futhi izixazululo ezinjalo kakade ziyathuthukiswa. Ukubukeka komkhiqizo ofanayo kulindelekile okungenani ku-Samsung, ngaphezu kwalokho, amaqembu onjiniyela azimele nawo asebenza kubalawuli abathuthuke kakhulu: Phison (PS5018-E18), Silicon Motion (SM2267), Marvell (88SS1321) ngisho nabangekho kahle kakhulu. -inkampani eyaziwayo i-Innogrit (IG5236).
Inkinga nje ukuthi bonke lobu bukhazikhazi bungase bungabonakali maduze. Ukuthuthukiswa kwesilawuli kuyinqubo ende, futhi ukubambezeleka okukhulu kuvame ukwenzeka ezigabeni zokugcina - phakathi nokulungiswa kwe-firmware noma phakathi nokuqinisekiswa. Ngaphezu kwalokho, imboni yonke manje isithinteke kakhulu ubhubhane lwe-coronavirus, yingakho ukukhishwa kwemikhiqizo emisha kubuyiselwe emuva esikhathini esizayo.
Ngamanye amazwi, ungalinda isikhathi eside ukuze uthole okuthile okungcono, kodwa uma ukusebenza okuphezulu kwe-disk subsystem kuyadingeka manje, khona-ke kunengqondo ukunamathela kulokho osekutholakala kakade - oshayelayo ku-Phison PS5016-E16 isilawuli. Nakuba bengakhethi umkhawulokudonsa ogcwele wemizila emine ye-PCIe 4.0, bangaziqhayisa ngokusebenza kahle kokusebenza kwamabhulokhi amancane, okuthi, ngokusho kwabathuthukisi, bafinyelele izinkulungwane ezingama-750 ze-IOPS. Lokhu kuqinisekiswa kokubili ukwakheka kwesilawuli, okusekelwe ku-dual-core 32-bit ARM Cortex R5 processor, kanye nesethi yamaqhinga okuphathelene: ukugcinwa kwesikhashana kwe-SLC ashukumisayo kanye nobuchwepheshe be-CoXProcessor 2.0 - ukusheshisa kwehadiwe kwamaketanga okusebenza ajwayelekile.
Kungani i-Seagate FireCuda 520?
Kwashiwo ngenhla ukuthi zonke izishayeli ze-NVMe zabathengi ezikhona ngokusekelwa kwe-PCIe 4.0 zakhiwe esisekelweni esifanayo - isilawuli se-Phison PS5016-E16. Kodwa-ke, lokhu akusho ukuthi ukuthatha i-PCIe 4.0 SSD yokuqala ohlangana nayo esitolo kuzoba umqondo omuhle. Lapha singancoma ukuthi unake i-Seagate FireCuda 520, kodwa hhayi nhlobo ngoba ufunda lesi sihloko kubhulogi lebhizinisi le-Seagate.
UDeveli usemininingwaneni futhi, uma uqala ukuqonda, i-Seagate FireCuda 520 ingase ibonakale ikhanga kakhulu kunezinye izindlela eziningi ngokusekelwe ku-chip efanayo ye-Phison PS5016-E16.

Futhi ngisho nalapho i-SSD isetshenziswa “njengokulahlwa kwefayela” (bona i-Data Drive Benchmark), nakuba lokhu, ukukhuluma ngokungananazi, kwenzeka kuyaqabukela.
Izinzuzo zejubane ze-FireCuda 520 zibonakala kalula lapho ukopisha amafayela ngokujwayelekile. Umdwebo ongezansi ubonisa imiphumela yokuhlolwa kweDiskBench lapho ukopisha uhla lwemibhalo olusebenzayo olunamafayela ahlukene anevolumu ephelele engaba ngu-20 GB ngaphakathi kwedrayivu. Yiqiniso, ukwanda okufana nokuhlolwa kokwenziwa akubonwa lapha, kodwa ukushintshela ku-PCIe 25 kunikeza i-30-4.0% yayo eyengeziwe ekusebenzeni ngaphandle kombuzo.
Ngokuhlukahluka, ungabheka nokuthi idrayivu ye-PCIe 4.0 ikuvumela ukuthi ulayishe ngokushesha kangakanani izinhlelo zemidlalo. Njengesibonelo, ngezansi yisikhathi sokulayisha izinga ku-Final Fantasy XIV StormBlood (ukukhethwa kwalo mdlalo othile kungenxa yamathuluzi okuqapha alula akhelwe kuwo). Lapha, inzuzo ehlinzekwa yi-FireCuda 520 phezu kwe-FireCuda 510 ingaphezu nje kwesekhondi, engabalulekile kangako, kodwa isabonakala.
Kepha ngaphansi kwemithwalo ejwayelekile yezindawo zokusebenza, i-PCI Express 4.0, njengoba besho, kufanele ube nayo. Iqiniso liwukuthi amakhompyutha ahloselwe ukudala okuqukethwe okuphrofeshinali afakwe ama-multi-core processors anamandla kakhulu nenkumbulo esheshayo. Futhi kulokhu, amabhodlela ohlelweni angavela kalula ku-subsystem yediski. Isibonelo, nakuba ochwepheshe abaningi bevidiyo ngaphambilini bebencamela ukwakha ama-RAID afanayo kumadrayivu e-SSD, manje sebengakwazi ukuhlangabezana nezidingo zabo nge-FireCuda 520, ephatha idatha ngesivinini esingaphezu kuka-4GB/s iyodwa.
Zonke lezi zingxabano zingasekelwa kalula yimiphumela yokuhlolwa kwe-SPECworkstation 3, okubonisa ngokucacile ukubaluleka kwedrayivu ene-interface yesimanje: i-FireCuda 520 ibhekana nezimo ezisindayo zomthwalo wediski ochwepheshe ngokwesilinganiso esingu-22% ngokushesha uma kuqhathaniswa ne-FireCuda 510. .
Kodwa kufanele kuqashelwe ngokukhethekile izinkomba Zokusebenza Okujwayelekile (isivinini esivamile sokusebenza namafayela lapho kugcinwa kungobo yomlando futhi kukopishwa, kanye nalapho kuthuthukiswa isofthiwe) kanye Nokuthuthukiswa Komkhiqizo (kukhombisa isivinini somsebenzi ezinhlelweni ze-CAD/CAD nalapho kuxazulula uketshezi oluyikhompyutha. izinkinga ze-dynamics). Lapha amandla akhona ku-FireCuda 520 abonakaliswa ngokukholisayo.
Isifingqo
Izibonelo ezinikeziwe zanele ukushiya ngaphandle kokungabaza ukuthi amadrayivu e-PCIe 4.0 akuvumela ngempela ukuthi uthole ukusebenza okuphezulu nokusabela okungcono lapho uxazulula imisebenzi edinga izinsiza. Ngakho-ke, lapho wakha uhlelo olusebenza kahle kakhulu kuma-multi-core AMD Ryzen 3000 noma ama-Threadripper 3000 processors, akufanele udebeselele ukusetshenziswa kwama-NVMe SSD esimanjemanje. I-Seagate FireCuda 520 ingaba yinketho efanelekile lapha: akukho lutho olusheshayo ezitolo okwamanje.
Ngokwemvelo, idrayivu ye-PCIe 4.0 izobiza kancane kune-FireCuda 510 efanayo, kodwa izizathu zalokhu ziqondwa kahle. Futhi into ebaluleke kakhulu ukuthi intengo ye-FireCuda 520 iyintengo yemakethe impela, ngoba le SSD ibiza cishe ngokufana nenye i-PCIe 4.0 drives evela kubakhiqizi besigaba sesithathu.
Amagama ambalwa mayelana nenkundla yokuhlola: Ukuhlolwa kokusebenza kwenziwa kusistimu esekelwe ku-Ryzen 9 3900X esekelwe ku-motherboard ye-ASRock X570 Creator futhi ifakwe i-16GB DDR4-3200 SDRAM (16-16-16-32). Isistimu yokusebenza Windows 10 Professional 1909 enomshayeli we-NVMe ojwayelekile I-NVM Express Controller 10.0.18362.1.
