Kukho iintlobo ezintathu zonxibelelwano lombane lwe-2.5-intshi / 3.5-intshi yokugcina iidiski: i-PCIe, i-SAS kunye ne-SATA, “Kwixesha elidlulileyo, uphuhliso lonxibelelwano lweziko ledatha lwaluqhutywa yi-IEEE okanye amaziko e-OIF-CEI okanye imibutho, kwaye inyaniso namhlanje itshintshe kakhulu.Abaqhubi beziko ledatha enkulu njengeAmazon, iApple, iFacebook, uGoogle, kunye neMicrosoft baqhuba itekhnoloji, bengalindelanga ukuba imigangatho igqitywe, kodwa ukuba umsebenzisi amisele yonke into.Ngokubhekiselele ekusebenzeni kwexesha elizayo kwe-PCIe SSD, i-SAS SSD kunye nemarike ye-SATA SSD, yabelana ngoqikelelo olwenziwe nguGartner kwireferensi yomntu wonke kunye nonxibelelwano.
Malunga PCIe
I-PCIe ngokungathandabuzekiyo ngowona mgangatho webhasi yezothutho uthandwa kakhulu, kwaye ihlaziywe rhoqo kwiminyaka yakutshanje: I-PCIe 3.0 iseyeyona idumileyo, i-PCIe 4.0 iyenyuka ngokukhawuleza, i-PCIe 5.0 iza kudibana nawe, ukucaciswa kwe-PCIe 6.0 kugqityiwe uguqulelo 0.5 , yaye inikwe amalungu ombutho, iya kukhutshwa kunyaka ozayo ngokohlelo lokugqibela olusemthethweni.
Uhlelo ngalunye lwenkcazo ye-PCIe luhamba ngeenguqulelo/izigaba ezintlanu ezahlukeneyo:
Inguqulo 0.3: Ingqikelelo yokuqala ebonisa iimpawu eziphambili kunye noyilo lwenkcazo entsha.
Inguqulo ye-0.5: Inkcazo yokuqala eyidrafti echonga yonke imiba yolwakhiwo olutsha, ibandakanya impendulo evela kumalungu ombutho ngokusekelwe kwinguqulo ye-0.3, kwaye ibandakanya izinto ezintsha ezicelwe ngamalungu kunye neempawu ezintsha.
Inguqulo ye-0.7: Idrafti epheleleyo, yonke imiba yenkcazo entsha inqunywe ngokupheleleyo, kwaye ukucaciswa kombane kufuneka kwakhona kuqinisekiswe yi-chip chip.Akukho zimpawu zintsha ziya kongezwa emva koko.
Inguqulelo 0.9: Idrafti yokugqibela apho amalungu ombutho anokuyila kwaye aphuhlise itekhnoloji kunye neemveliso zabo.
Inguqulo ye-1.0: Ukukhutshwa okusemthethweni kokugqibela, ukukhululwa koluntu.
Enyanisweni, emva kokukhululwa kwenguqulo ye-0.5, abavelisi banokuqala ukuyila iitshiphusi zokuvavanya ukulungiselela umsebenzi olandelayo kwangaphambili.
PCIe 6.0 akukho ngaphandle.Xa umva uhambelana ne-PCIe 5.0/4.0/3.0/2.0/1.0, ireyithi yedatha okanye i-I/O bandwidth iya kuphinda kabini kwakhona kwi-64GT/s, kunye ne-bandwidth yangempela ye-PCIe 6.0 × 1 yi-8GB / s.I-PCIe 6.0×16 ine-128GB/s kwicala elinye kunye ne-256GB/s macala omabini.
I-PCIe 6.0 iya kuqhubeka ne-128b / 130b encoding eyaziswa kwixesha le-PCIe 3.0, kodwa yongeza i-modulation entsha ye-pulse amplitude i-PAM4 ukuze ithathe indawo ye-PCIe 5.0 NRZ, engakwazi ukupakisha idatha eninzi kwitshaneli enye ngexesha elifanayo, kunye nezantsi. ukulungiswa kwempazamo ye-latency phambili (i-FEC) kunye neendlela ezinxulumene nokuphucula ukusebenza kakuhle kwe-bandwidth.
Malunga ne-SAS
Uthotho Oluqhotyoshelweyo SCSI ujongano (SAS), SAS sisizukulwana esitsha sobuchwepheshe SCSI, kwaye ethandwayo Serial ATA (SATA) hard disk iyafana, kukusetyenziswa kothotho lweteknoloji ukufumana isantya esiphezulu sothumelo, kwaye ngokunciphisa umgca woqhagamshelo ukuya. ukuphucula indawo yangaphakathi.I-SAS lujongano olutsha oluphuhliswe emva kojongano olunxuseneyo lwe-SCSI.Olu jongano lwenzelwe ukuphucula ukusebenza, ukufumaneka, kunye ne-scalability yenkqubo yokugcina, ukubonelela ngokuhambelana ne-SATA hard drives.I-interface ye-SAS ayibonakali nje ngokufana ne-SATA, kodwa ibuyela ngasemva iyahambelana nomgangatho we-SATA.I-Backpanel yenkqubo ye-SAS inokudibanisa zombini i-port-port, i-high-performance SAS drives kunye ne-high-capacity, i-SATA yexabiso eliphantsi.Ngenxa yoko, ii-SAS drives kunye ne-SATA drives zinokuhlalisana kwinkqubo efanayo yokugcina.Nangona kunjalo, kufuneka kuqatshelwe ukuba iinkqubo ze-SATA azihambelani ne-SAS, ngoko ke iidrive ze-SAS azikwazi ukuqhagamshelwa kwii-backplanes ze-SATA.
Xa kuthelekiswa nophuhliso olukhulu oluya phambili lwenkcazo ye-PCIe kule minyaka yamva nje, ukucaciswa kwe-SAS kuye kwavela ngokuthe ngcembe, kwaye ngoNovemba ka-2019, ukucaciswa kwe-SAS 4.1 kusetyenziswa inqanaba lojongano lwe-24Gbps kwakhululwa ngokusemthethweni, kwaye isizukulwana esilandelayo se-SAS 5.0 sicacisiwe. ukulungiswa, okuya kwandisa ngakumbi ireyithi ye-interface ukuya kwi-56Gbps.
Okwangoku, kwiimveliso ezininzi ezintsha, i-SAS interface ye-SSD ye-SSD imbalwa kakhulu, umlawuli wobugcisa bomsebenzisi we-Intanethi wathi abasebenzisi be-Intanethi abafane basebenzise i-SAS SSD, ikakhulu ngenxa yezizathu zokusebenza kweendleko, i-SAS SSD phakathi kwe-PCIe kunye ne-SATA SSD, ihlazo kakhulu, ukusebenza kunoko. ayinakufaniswa nePCIe.Amaziko edatha amakhulu kakhulu akhetha i-PCIe, ixabiso alikwazi ukufumana i-SATA SSD, abathengi abaqhelekileyo abathengi bakhetha i-SATA SSD.
Malunga neSATA
I-SATA yi-Serial ATA (i-Serial Advanced Technology Attachment), ekwabizwa ngokuba yi-Serial ATA, eyinkcazo yojongano lwediski enzima ecetywe ngokudibeneyo yi-Intel, i-IBM, i-Dell, i-APT, i-Maxtor, kunye ne-Seagate.
I-SATA interface isebenzisa iintambo ze-4 ukuhambisa idatha, isakhiwo sayo silula, i-Tx +, i-Tx- ibonisa umgca wedatha yokwahlukana kwemveliso, ehambelanayo, i-Rx +, i-Rx- ibonisa umgca wedatha yokuhlukanisa igalelo, njengeyona ndlela isetyenziswa kakhulu kwi-hard disk interface kwimarike, inguqulo yangoku ethandwayo yi-3.0, inzuzo enkulu ye-SATA 3.0 interface kufuneka ibe ikhulile, i-Ordinary 2.5-inch SSD kunye ne-HDD hard disks zisebenzisa le interface, i-theory transmission bandwidth ye-6Gbps, nangona ithelekiswa ne-interface entsha ye-10Gbps kunye ne-32Gbps bandwidth apho. ngumsantsa othile, kodwa i-2.5-intshi ye-SSD eqhelekileyo inokuhlangabezana neemfuno zesicelo semihla ngemihla zabasebenzisi abaninzi, i-500MB/s okanye isantya sokufunda nokubhala sanele.
