Hariho ubwoko butatu bwumuriro wamashanyarazi kuri disiki zibikwa ya santimetero 2,5 / PC-PC: PCIe, SAS na SATA, "Kera, iterambere ryikigo gihuza amakuru ryatwarwaga nukuri na IEEE cyangwa OIF-CEI ibigo cyangwa amashyirahamwe, no muri ukuri uyumunsi yarahindutse cyane.Abakozi bashinzwe amakuru manini nka Amazon, Apple, Facebook, Google, na Microsoft batwara ikoranabuhanga, ntabwo byanze bikunze bategereje ko ibipimo byuzuzwa, ariko kubakoresha bategeka byose.Kubijyanye n'imikorere iri imbere ya PCIe SSD, SAS SSD na SATA SSD, sangira iteganyagihe ryakozwe na Gartner kubantu bose bavugana kandi bavugane.
Ibyerekeye PCIe
PCIe ntagushidikanya ko bisi itwara abantu benshi cyane, kandi yagiye ivugururwa kenshi mumyaka yashize: PCIe 3.0 iracyakunzwe cyane, PCIe 4.0 irazamuka vuba, PCIe 5.0 igiye guhura nawe, PCIe 6.0 ibisobanuro byujujwe verisiyo 0.5 , kandi igahabwa abanyamuryango b'umuryango, izasohoka umwaka utaha kuri gahunda yanyuma yanyuma.
Buri cyegeranyo cyibisobanuro bya PCIe kinyura muburyo butanu / ibyiciro:
Verisiyo 0.3: Igitekerezo cyambere cyerekana ibintu byingenzi nuburyo bwububiko bushya.
Verisiyo 0.5: Umushinga wambere wibisobanuro byerekana ibintu byose byububiko bushya, bikubiyemo ibitekerezo byatanzwe nabanyamuryango bishingiye kuri verisiyo 0.3, kandi bikubiyemo ibintu bishya byasabwe nabanyamuryango hiyongereyeho ibintu bishya.
Verisiyo 0.7: Inyandiko yuzuye, ibintu byose byerekeranye nibisobanuro bishya byagenwe neza, kandi amashanyarazi agomba no kugenzurwa na chip yikizamini.Nta bintu bishya bizongerwaho nyuma yibyo.
Verisiyo 0.9: Umushinga wanyuma abanyamuryango bishyirahamwe bashobora gushushanya no guteza imbere tekinoroji nibicuruzwa byabo.
Verisiyo 1.0: Isohora ryanyuma, gusohora kumugaragaro.
Mubyukuri, nyuma yo gusohora verisiyo 0.5, abayikora barashobora gutangira gushushanya chip yo kwipimisha kugirango bategure imirimo ikurikira mbere.
PCIe 6.0 nayo ntisanzwe.Iyo gusubira inyuma bihujwe na PCIe 5.0 / 4.0 / 3.0 / 2.0 / 1.0, igipimo cyamakuru cyangwa umurongo wa I / O uzongera gukuba kabiri kuri 64GT / s, kandi umurongo mugari wa PCIe 6.0 × 1 ni 8GB / s.PCIe 6.0 × 16 ifite 128GB / s mu cyerekezo kimwe na 256GB / s mu byerekezo byombi.
PCIe 6.0 izakomeza kodegisi ya 128b / 130b yatangijwe mugihe cya PCIe 3.0, ariko wongereho pulse amplitude modulation PAM4 kugirango isimbuze PCIe 5.0 NRZ, ishobora gupakira amakuru menshi mumurongo umwe mugihe kimwe, kimwe no hasi ubukererwe imbere ikosora ikosora (FEC) hamwe nuburyo bujyanye no kunoza imikorere yumurongo.
Ibyerekeye SAS
Serial Yometse kuri SCSI Imigaragarire (SAS), SAS nigisekuru gishya cyikoranabuhanga rya SCSI, kandi disiki izwi cyane ya Serial ATA (SATA) ni imwe, ni ugukoresha tekinoroji ikurikirana kugirango ubone umuvuduko mwinshi woherejwe, no kugabanya umurongo uhuza kuri kunoza umwanya w'imbere.SAS ni intera nshya yatejwe imbere nyuma ya parike ya SCSI.Iyi interface yagenewe kunoza imikorere, kuboneka, hamwe nubunini bwa sisitemu yo kubika, itanga guhuza na disiki zikomeye za SATA.Imigaragarire ya SAS ntabwo isa gusa na SATA, ariko isubira inyuma ihuza na SATA.Backpanel ya sisitemu ya SAS irashobora guhuza ibyambu byombi, ibyerekezo byinshi bya SAS hamwe nubushobozi buhanitse, buke bwa SATA.Nkigisubizo, disiki ya SAS na SATA irashobora kubana muri sisitemu imwe yo kubika.Ariko, twakagombye kumenya ko sisitemu ya SATA idahuye na SAS, bityo drives ya SAS ntishobora guhuzwa ninyuma ya SATA.
Ugereranije niterambere ryinshi ryiterambere ryibisobanuro bya PCIe mumyaka yashize, ibisobanuro bya SAS byahindutse buhoro buhoro bucece, kandi mu Gushyingo 2019, ibisobanuro bya SAS 4.1 ukoresheje igipimo cya interineti 24Gbps byashyizwe ahagaragara kumugaragaro, kandi ibisekuruza bizaza SAS 5.0 nabyo biri muri kwitegura, bizarushaho kongera igipimo cyimbere kuri 56Gbps.
Kugeza ubu, mu bicuruzwa byinshi bishya, interineti ya SAS SSD SSD ni mike cyane, umuyobozi wa tekinike w’umukoresha wa interineti yavuze ko abakoresha interineti badakunze gukoresha SAS SSD, cyane cyane kubera impamvu z’ibiciro, SAS SSD hagati ya PCIe na SATA SSD, biteye isoni, imikorere irashobora ntabwo wagereranywa na PCIe.Ultra-nini yamakuru makuru ahitamo PCIe, igiciro ntigishobora kubona SATA SSD, abakiriya basanzwe bahitamo SATA SSD.
Ibyerekeye SATA
SATA ni Serial ATA (Serial Advanced Technology Attachment), izwi kandi nka Serial ATA, ikaba igizwe na disiki ya disiki igaragara hamwe na Intel, IBM, Dell, APT, Maxtor, na Seagate.
Imigaragarire ya SATA ikoresha insinga 4 zo kohereza amakuru, imiterere yayo iroroshye, Tx +, Tx- yerekana ibisohoka bitandukanya umurongo utandukanya amakuru, bihuye, Rx +, Rx- byerekana ibyinjijwe bitandukanye mumirongo, nkimikoreshereze ya disiki ikoreshwa cyane mumasoko, verisiyo ikunzwe ubu ni 3.0, inyungu nini ya interineti ya SATA 3.0 igomba kuba ikuze, Ubusanzwe disiki isanzwe ya santimetero 2,5 ya SSD na HDD ikoresha iyi interineti, umurongo wa tewolojiya ya terevisiyo ya 6Gbps, nubwo ugereranije nuburyo bushya bwa 10Gbps na 32Gbps ni icyuho runaka, ariko SSD isanzwe ya santimetero 2,5 irashobora guhaza ibyifuzo bya buri munsi byabakoresha benshi, 500MB / s cyangwa rero gusoma no kwandika umuvuduko urahagije.
