Akwai nau'ikan musaya na lantarki guda uku don faifan ajiya na 2.5-inch / 3.5-inch: PCIe, SAS da SATA, “A da, ci gaba da haɗin gwiwar cibiyar sadarwa ta IEEE ko OIF-CEI cibiyoyi ko ƙungiyoyi ne ke jagorantar haɓaka, kuma a zahiri a yau ya canza sosai. Amma game da aikin gaba na PCIe SSD, SAS SSD da SATA SSD kasuwa, raba hasashen da Gartner ya yi don tunani da sadarwar kowa.
Game da PCIe
Babu shakka PCIe shine mafi mashahurin ma'aunin bas na sufuri, kuma an sabunta shi akai-akai a cikin 'yan shekarun nan: PCIe 3.0 har yanzu shine mafi mashahuri, PCIe 4.0 yana tashi da sauri, PCIe 5.0 yana gab da saduwa da ku, an kammala ƙayyadaddun PCIe 6.0 sigar 0.5, kuma an ba membobin ƙungiyar, za a fito da su a shekara mai zuwa akan jadawalin hukuma.
Kowane bugu na ƙayyadaddun PCIe yana wucewa ta nau'ikan / matakai daban-daban guda biyar:
Shafin 0.3: Ra'ayi na farko wanda ke gabatar da mahimman fasali da gine-ginen sabon ƙayyadaddun bayanai.
Sigar 0.5: Takaddun daftarin farko wanda ke gano duk bangarorin sabon gine-gine, ya haɗa da martani daga membobin ƙungiyar dangane da sigar 0.3, kuma ya haɗa sabbin fasalulluka waɗanda membobin suka buƙata tare da sabbin abubuwa.
Sigar 0.7: Cikakken daftarin, duk bangarorin sabon ƙayyadaddun an ƙididdige su sosai, kuma ƙayyadaddun wutar lantarki dole ne a tabbatar da guntuwar gwaji. Ba za a ƙara sabbin abubuwa ba bayan haka.
Shafin 0.9: Ƙarshe na ƙarshe wanda membobin ƙungiyar za su iya tsarawa da haɓaka fasaharsu da samfuran su.
Shafin 1.0: Sakin hukuma na ƙarshe, sakin jama'a.
A zahiri, bayan fitowar sigar 0.5, masana'antun sun riga sun fara ƙirar kwakwalwan kwamfuta don shirya don aiki na gaba a gaba.
PCIe 6.0 ba banda. Lokacin da baya da jituwa tare da PCIe 5.0/4.0/3.0/2.0/1.0, ƙimar bayanai ko bandwidth na I/O zai sake ninka zuwa 64GT/s, kuma ainihin bandwidth unidirectional na PCIe 6.0 × 1 shine 8GB/s. PCIe 6.0 × 16 yana da 128GB/s a hanya ɗaya da 256GB/s a duka kwatance.
PCIe 6.0 za ta ci gaba da shigar da 128b / 130b da aka gabatar a cikin zamanin PCIe 3.0, amma ƙara sabon nau'in nau'in bugun jini na PAM4 don maye gurbin PCIe 5.0 NRZ, wanda zai iya fakitin ƙarin bayanai a cikin tashar guda ɗaya a cikin adadin lokaci guda, da ƙananan latency gaba da gyara kuskuren kuskure (FEC).
Game da SAS
Serial Attached SCSI interface (SAS), SAS wani sabon ƙarni ne na fasahar SCSI, kuma mashahurin Serial ATA (SATA) hard disk iri ɗaya ne, ana amfani da fasahar serial don samun saurin watsawa, da kuma rage layin haɗin gwiwa don inganta sararin ciki. SAS sabon keɓantawa ne da aka haɓaka bayan ƙirar SCSI mai kama da juna. An ƙera wannan ƙirar don haɓaka aiki, samuwa, da haɓakar tsarin ajiya, samar da dacewa tare da tukwici na SATA. SAS dubawa ba wai kawai yayi kama da SATA ba, amma yana dacewa da baya tare da ma'aunin SATA. Sashin baya na tsarin SAS zai iya haɗa duka biyu-tashar jiragen ruwa, manyan ayyukan SAS masu aiki da babban ƙarfi, masu tafiyar SATA masu rahusa. A sakamakon haka, SAS tafiyarwa da SATA tafiyarwa iya zama tare a cikin wannan tsarin ajiya. Duk da haka, ya kamata a lura cewa tsarin SATA ba su dace da SAS ba, don haka SAS tafiyarwa ba za a iya haɗa su zuwa SATA backplanes.
Idan aka kwatanta da babban ci gaban ci gaba na ƙayyadaddun PCIe a cikin 'yan shekarun nan, ƙayyadaddun SAS a hankali ya samo asali cikin nutsuwa, kuma a cikin Nuwamba 2019, an fitar da ƙayyadaddun SAS 4.1 ta amfani da ƙimar ƙirar 24Gbps bisa hukuma, kuma ƙayyadaddun ƙarni na gaba SAS 5.0 shima yana cikin shiri, wanda zai ƙara haɓaka ƙimar dubawa zuwa 56Gbps.
A halin yanzu, a yawancin sabbin samfura, SAS interface SSD SSD kaɗan ne, daraktan fasaha na mai amfani da Intanet ya ce masu amfani da Intanet ba safai suke amfani da SAS SSD ba, musamman saboda dalilai masu tsada, SAS SSD tsakanin PCIe da SATA SSD, abin kunya sosai, aikin ba za a iya kwatanta shi da PCIe ba. Manyan cibiyoyin bayanai sun zaɓi PCIe, farashin ba zai iya samun SATA SSD ba, abokan ciniki na yau da kullun sun zaɓi SATA SSD.
Game da SATA
SATA Serial ATA ne (Serial Advanced Technology Attachment), kuma aka sani da Serial ATA, wanda ke da ƙayyadaddun ƙayyadaddun ƙayyadaddun faifan diski wanda Intel, IBM, Dell, APT, Maxtor, da Seagate suka gabatar.
SATA ke dubawa yana amfani da igiyoyi 4 don watsa bayanai, tsarinsa yana da sauƙi, Tx +, Tx- yana nuna layin bayanan fitarwa daban-daban, daidaitaccen, Rx +, Rx- yana nuna layin bambance-bambancen shigarwar, kamar yadda mafi yawan fa'idar faifan diski a kasuwa, sanannen sigar yanzu shine 3.0, babbar fa'idar SATA 3.0 interface yakamata ya zama balagagge, Talakawa na watsa shirye-shiryen watsa shirye-shirye na SSD 2 HD5. na 6Gbps, ko da yake idan aka kwatanta da sabon dubawa na 10Gbps da 32Gbps bandwidth akwai wani tazari, amma talakawa 2.5-inch SSD iya saduwa da kullum aikace-aikace bukatun na mafi yawan masu amfani, 500MB/s ko haka karanta da rubuta gudun ya isa.
