Kukho iintlobo ezintathu zeendawo zokunxibelelana ngombane kwiidiski zokugcina eziyi-2.5-intshi / 3.5-intshi: i-PCIe, i-SAS kunye ne-SATA, "Ngaphambili, uphuhliso lonxibelelwano lweziko ledatha lwaluqhutywa zizikhungo okanye imibutho ye-IEEE okanye i-OIF-CEI, kwaye eneneni namhlanje lutshintshe kakhulu. Abaqhubi beziko ledatha elikhulu njenge-Amazon, i-Apple, i-Facebook, i-Google, kunye ne-Microsoft baqhuba ubuchwepheshe, bengalindeli ukuba imigangatho igqitywe, kodwa ukuba umsebenzisi alawule yonke into. Ngokuphathelele ukusebenza kwexesha elizayo kwimarike ye-PCIe SSD, i-SAS SSD kunye ne-SATA SSD, yabelana ngengqikelelo eyenziwe yiGartner ukuze wonke umntu abhekisele kuyo kwaye anxibelelane.
Malunga ne-PCIe
I-PCIe ngokungathandabuzekiyo yeyona migangatho idumileyo yeebhasi zothutho, kwaye ihlaziywe rhoqo kwiminyaka yakutshanje: I-PCIe 3.0 iseyeyona idumileyo, i-PCIe 4.0 ikhula ngokukhawuleza, i-PCIe 5.0 iza kuhlangabezana nawe, iinkcukacha ze-PCIe 6.0 zigqityiwe inguqulelo 0.5, kwaye zinikwe amalungu ombutho, ziya kukhutshwa kunyaka olandelayo ngokweshedyuli inguqulelo yokugqibela esemthethweni.
Uhlelo ngalunye lwenkcazo ye-PCIe ludlula kwiinguqulelo/amanqanaba amahlanu ahlukeneyo:
Inguqulelo 0.3: Ingcamango yokuqala eveza iimpawu eziphambili kunye noyilo lweenkcukacha ezintsha.
Inguqulelo 0.5: Inkcazo yokuqala yoyilo echaza zonke iinkalo zoyilo olutsha, ibandakanya impendulo evela kumalungu ombutho ngokusekelwe kwinguqulelo 0.3, kwaye ibandakanya iimpawu ezintsha ezicelwe ngamalungu kunye neempawu ezintsha.
Inguqulelo 0.7: Uyilo olupheleleyo, zonke iinkalo zeenkcukacha ezintsha zimiselwe ngokupheleleyo, kwaye iinkcukacha zombane nazo kufuneka ziqinisekiswe yitshiphu yovavanyo. Akukho zimpawu zintsha ziya kongezwa emva koko.
Inguqulelo 0.9: Uyilo lokugqibela apho amalungu ombutho anokuyila aze aphuhlise ubuchwepheshe kunye neemveliso zawo.
Inguqulelo 1.0: Ukukhutshwa kokugqibela okusemthethweni, ukukhutshwa esidlangalaleni.
Enyanisweni, emva kokukhutshwa kwenguqulelo 0.5, abavelisi sele benokuqala ukuyila iitships zovavanyo ukulungiselela umsebenzi olandelayo kwangaphambili.
I-PCIe 6.0 ayifani nayo. Xa ihambelana ne-backward ne-PCIe 5.0/4.0/3.0/2.0/1.0, izinga ledatha okanye i-I/O bandwidth iya kuphinda kabini ibe yi-64GT/s, kwaye i-bandwidth yokwenyani ye-PCIe 6.0×1 yi-8GB/s. I-PCIe 6.0×16 ine-128GB/s kwicala elinye kunye ne-256GB/s kwicala ngalinye.
I-PCIe 6.0 iza kuqhubeka nokufaka ikhowudi ye-128b/130b eyaziswa kwixesha le-PCIe 3.0, kodwa yongeza i-pulse amplitude modulation entsha ye-PAM4 ukuze ithathe indawo ye-PCIe 5.0 NRZ, enokupakisha idatha engaphezulu kwitshaneli enye ngexesha elifanayo, kunye nokulungiswa kwempazamo ye-latency forward error (FEC) kunye neendlela ezinxulumene noko zokuphucula ukusebenza kakuhle kwe-bandwidth.
Malunga ne-SAS
I-Serial Attached SCSI interface (SAS), i-SAS sisizukulwana esitsha setekhnoloji ye-SCSI, kwaye i-hard disk edumileyo ye-Serial ATA (SATA) iyafana, kukusetyenziswa kwetekhnoloji ye-serial ukufumana isantya esiphezulu sokudlulisa, kunye nokunciphisa umgca woqhagamshelo ukuphucula indawo yangaphakathi. I-SAS yi-interface entsha eyenziwe emva kwe-interface ye-SCSI ehambelanayo. Le interface yenzelwe ukuphucula ukusebenza, ukufumaneka, kunye nokukhula kwenkqubo yokugcina, ibonelela ngokuhambelana nee-hard drive ze-SATA. I-interface ye-SAS ayibonakali nje kuphela njenge-SATA, kodwa iyahambelana nomgangatho we-SATA. I-Backpanel yenkqubo ye-SAS inokudibanisa zombini ii-drive ze-SAS ezineeport ezimbini, ezisebenza kakhulu kunye nee-SATA drives ezinomthamo ophezulu, ezingabizi kakhulu. Ngenxa yoko, ii-SAS drives kunye nee-SATA drives zinokudibana kwinkqubo yokugcina efanayo. Nangona kunjalo, kufuneka kuqatshelwe ukuba iinkqubo ze-SATA azihambelani ne-SAS, ngoko ke ii-SAS drives azinakunxibelelana nee-backplanes ze-SATA.
Xa kuthelekiswa nophuhliso olukhulu lwe-PCIe specification kwiminyaka yakutshanje, i-SAS specification iye yatshintsha kancinci kancinci, kwaye ngoNovemba ka-2019, i-SAS 4.1 specification esebenzisa i-24Gbps interface rate yakhutshwa ngokusesikweni, kwaye i-SAS 5.0 specification yesizukulwana esilandelayo nayo iyalungiselelwa, nto leyo eya kunyusa i-interface rate ukuya kwi-56Gbps.
Okwangoku, kwiimveliso ezininzi ezintsha, i-SSD ye-SAS interface incinci kakhulu, umlawuli wezobugcisa womsebenzisi we-intanethi uthe 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 akunakuthelekiswa ne-PCIe. Amaziko edatha amakhulu kakhulu akhetha i-PCIe, ixabiso alinakufumana i-SATA SSD, abathengi abaqhelekileyo bakhetha i-SATA SSD.
Malunga ne-SATA
I-SATA yi-Serial ATA (Serial Advanced Technology Attachment), eyaziwa ngokuba yi-Serial ATA, eyinkcazo ye-hard disk interface ecetywayo ngokudibeneyo yi-Intel, i-IBM, i-Dell, i-APT, i-Maxtor, kunye ne-Seagate.
I-SATA interface isebenzisa iintambo ezi-4 ukudlulisa idatha, ulwakhiwo lwayo lulula, i-Tx+, i-Tx- ibonisa umgca wedatha yomahluko wemveliso, ehambelanayo, i-Rx+, i-Rx- ibonisa umgca wedatha yomahluko wengeniso, njengeyona interface yediski enzima esetyenziswa kakhulu kwimarike, inguqulelo ethandwayo yangoku yi-3.0, inzuzo enkulu ye-SATA 3.0 interface kufuneka ibe mdala, ii-SSD eziqhelekileyo ze-2.5-intshi kunye neediski ze-HDD eziqinileyo zisebenzisa le interface, i-bandwidth yokudlulisela yethiyori ye-6Gbps, nangona xa kuthelekiswa ne-interface entsha ye-10Gbps kunye ne-32Gbps bandwidth kukho umsantsa othile, kodwa i-SSD eqhelekileyo ye-2.5-intshi inokuhlangabezana neemfuno zesicelo semihla ngemihla sabasebenzisi abaninzi, isantya sokufunda nokubhala se-500MB/s okanye ngaphezulu sanele.
