E toru ngā momo atanga hiko mō ngā kōpae rokiroki 2.5-inihi / 3.5-inihi: PCIe, SAS me SATA, "I mua, ko te whanaketanga o te hononga pokapū raraunga i akiakihia e ngā umanga, ngā rōpū rānei a IEEE, a OIF-CEI rānei, ā, kua tino rerekē i ēnei rā. Ko ngā kaiwhakahaere pokapū raraunga nui pēnei i a Amazon, Apple, Facebook, Google, me Microsoft kei te akiaki i te hangarau, ehara i te mea me tatari kia oti ngā paerewa, engari kia whakahaua e te kaiwhakamahi ngā mea katoa. Mō te mahi a meake nei o te mākete PCIe SSD, SAS SSD me SATA SSD, tohaina he matapae nā Gartner hei tohutoro me te whakawhitiwhiti kōrero mā te katoa.
Mō PCIe
Ko te PCIe te paerewa pahi kawe waka rongonui rawa atu, ā, kua whakahoutia pinepinetia i ngā tau tata nei: ko te PCIe 3.0 tonu te mea tino rongonui, kei te tere piki haere te PCIe 4.0, kei te tata te tūtaki ki a koe mō te PCIe 5.0, kua oti te putanga 0.5 o ngā whakatakotoranga PCIe 6.0, ā, kua tukuna ki ngā mema o te whakahaere, ka tukuna i te tau e tū mai nei te putanga mana whakamutunga i te wā kua whakaritea.
E rima ngā putanga/wāhanga rerekē o ia putanga o te whakatakotoranga PCIe:
Putanga 0.3: He ariā tuatahi e whakaatu ana i ngā āhuatanga matua me te hoahoanga o te whakatakotoranga hou.
Putanga 0.5: He tauira whakatakotoranga tuatahi e tautuhi ana i ngā āhuatanga katoa o te hoahoanga hou, e whakauru ana i ngā urupare mai i ngā mema o te whakahaere i runga i te putanga 0.3, ā, e whakauru ana hoki i ngā āhuatanga hou i tonoa e ngā mema me ngā āhuatanga hou.
Putanga 0.7: Kua oti te tauira, kua tino whakatauhia ngā āhuatanga katoa o te whakatakotoranga hou, ā, me manatoko hoki te whakatakotoranga hiko e te maramara whakamātautau. Kāore he āhuatanga hou e tāpirihia i muri i tēnā.
Putanga 0.9: Tauira whakamutunga e taea ai e ngā mema o te whakahaere te hoahoa me te whakawhanake i ā rātou ake hangarau me ngā hua.
Putanga 1.0: Tukunga whakamutunga, tukunga tūmatanui.
Ina hoki, i muri i te tukunga o te putanga 0.5, ka taea e ngā kaihanga te tīmata ki te hoahoa i ngā maramara whakamātautau hei whakarite mō ngā mahi e whai ake nei i mua.
Kāore te PCIe 6.0 i te rerekē. Ina hototahi whakamuri ki te PCIe 5.0/4.0/3.0/2.0/1.0, ka rua anō te tere raraunga, te whānui I/O rānei, ki te 64GT/s, ā, ko te whānui kotahi-ara o te PCIe 6.0×1 he 8GB/s. Ko te PCIe 6.0×16 he 128GB/s i te taha kotahi, ā, ko te 256GB/s i ngā taha e rua.
Ka haere tonu te PCIe 6.0 i te whakakōwae 128b/130b i whakaurua mai i te wā PCIe 3.0, engari ka tāpirihia he whakarerekētanga kaha pāoro hou PAM4 hei whakakapi i te PCIe 5.0 NRZ, ka taea te tākai i ngā raraunga maha atu i roto i te hongere kotahi i roto i te wā kotahi, me te whakatikatika hapa whakamua iti-whakaroa (FEC) me ngā tikanga e pā ana ki te whakapai ake i te pai o te whānui o te hononga.
Mō SAS
Ko te atanga SCSI Serial Attached (SAS), he whakatupuranga hou te SAS o te hangarau SCSI, ā, ko te kōpae mārō Serial ATA (SATA) rongonui he rite tonu, ko te whakamahinga o te hangarau raupapa hei tiki tere ake i te tuku, me te whakapoto i te raina hononga hei whakapai ake i te wāhi o roto. He atanga hou te SAS i whakawhanakehia i muri i te atanga SCSI whakarara. Kua hangaia tēnei atanga hei whakapai ake i te mahi, te wātea, me te tauine o te pūnaha rokiroki, me te whakarato hototahi ki ngā puku mārō SATA. Kāore te atanga SAS i te āhua rite ki te SATA anake, engari he hototahi whakamuri ki te paerewa SATA. Ka taea e te Backpanel o te pūnaha SAS te hono i ngā puku SAS rua-tauranga, mahi-teitei me ngā puku SATA teitei-kaha, utu iti. Nō reira, ka taea e ngā puku SAS me ngā puku SATA te noho tahi i roto i te pūnaha rokiroki kotahi. Heoi, me mōhio kāore ngā pūnaha SATA e hototahi ki te SAS, nō reira kāore e taea te hono i ngā puku SAS ki ngā papa whakamuri SATA.
Ki te whakataurite ki te whanaketanga nui o te whakatakotoranga PCIe i ngā tau tata nei, kua āta whanake haere te whakatakotoranga SAS, ā, i te Whiringa-ā-rangi 2019, i tukuna mana te whakatakotoranga SAS 4.1 e whakamahi ana i te tere atanga 24Gbps, ā, kei te whakaritea hoki te whakatakotoranga SAS 5.0 o te whakatupuranga e whai ake nei, ka piki ake te tere atanga ki te 56Gbps.
I tēnei wā, he iti noa iho ngā hua hou o te SAS SSD SSD, ā, i kī tētahi kaiwhakahaere hangarau o te Ipurangi he onge te whakamahi a ngā kaiwhakamahi Ipurangi i te SAS SSD, ko te nuinga nā te utu nui, he tino whakama te SAS SSD i waenga i te PCIe me te SATA SSD, kāore e taea te whakarite i te mahi ki te PCIe. Ka whiriwhiria e ngā pokapū raraunga tino nui te PCIe, kāore e taea te utu te SATA SSD, engari ka whiriwhiria e ngā kaihoko noa te SATA SSD.
Mō SATA
Ko te SATA he Serial ATA (Serial Advanced Technology Attachment), e mōhiotia ana ko te Serial ATA, he whakatakotoranga atanga kōpae mārō i whakatakotoria ngātahitia e Intel, IBM, Dell, APT, Maxtor, me Seagate.
E whā ngā taura e whakamahia ana e te atanga SATA hei tuku raraunga, he māmā noa iho tōna hanganga, ko Tx+, ko Tx- te tohu i te rārangi raraunga rerekētanga putanga, ko Rx+, ko Rx- te tohu i te rārangi raraunga rerekētanga tāuru, koinei te atanga kōpae mārō e whakamahia whānuitia ana i te mākete, ko te putanga rongonui o nāianei ko te 3.0, ko te painga nui o te atanga SATA 3.0 me pakari. Ko ngā kōpae mārō SSD me HDD 2.5-inihi noa e whakamahi ana i tēnei atanga, ko te whānui o te tukunga ariā he 6Gbps, ahakoa he āputa kei te whakatauritea ki te atanga hou o te whānui o te 10Gbps me te 32Gbps, engari ka taea e te SSD 2.5-inihi noa te whakatutuki i ngā hiahia o ia rā o te nuinga o ngā kaiwhakamahi, he nui te tere pānui me te tuhi 500MB/s pea.
