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 ne ko ƙungiyoyi, kuma a cikin gaskiya a yau ta canza sosai.Manyan ma'aikatan cibiyar bayanai kamar Amazon, Apple, Facebook, Google, da Microsoft suna tuƙi fasahar, ba lallai ba ne suna jiran ƙa'idodi don kammalawa, amma don mai amfani ya faɗi komai.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 shahara, 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 wa membobin kungiyar, za a sake shi a shekara mai zuwa akan jadawalin ƙarshe na 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.

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 rikodin rikodin 128b/130b da aka gabatar a cikin zamanin PCIe 3.0, amma ƙara sabon ƙirar bugun bugun jini PAM4 don maye gurbin PCIe 5.0 NRZ, wanda zai iya fakitin ƙarin bayanai a cikin tashoshi ɗaya a cikin adadin lokaci ɗaya, da ƙarancin ƙarancin lokaci. Gyara kuskuren latency gaba (FEC) da hanyoyin da ke da alaƙa don haɓaka ingancin bandwidth.
Game da SAS
Serial Attached SCSI interface (SAS), SAS 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, kuma ta hanyar rage layin haɗin gwiwa zuwa 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 a hankali, kuma a cikin Nuwamba 2019, an fitar da ƙayyadaddun SAS 4.1 ta amfani da ƙimar ƙirar 24Gbps bisa hukuma, kuma ƙayyadaddun SAS 5.0 na gaba shima yana cikin. shirye-shiryen, wanda zai ƙara haɓaka ƙimar sadarwa zuwa 56Gbps.
A halin yanzu, a cikin sabbin samfura da yawa, 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 zai iya. ba za a kwatanta da PCIe.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 dubawa yana amfani da igiyoyi 4 don watsa bayanai, tsarinsa yana da sauƙi, Tx +, Tx- yana nuna layin bayanan fitarwa na daban, daidai, Rx +, Rx- yana nuna layin bayanan shigar da bayanai, kamar yadda aka fi amfani dashi a cikin kasuwa. sanannen sigar yanzu shine 3.0, babban fa'idar SATA 3.0 interface yakamata ya zama balagagge, Talakawa 2.5-inch SSD da HDD hard disks suna amfani da wannan keɓancewa, bandwidth watsa ka'idar na 6Gbps, kodayake idan aka kwatanta da sabon ƙirar 10Gbps da 32Gbps bandwidth a can. wani gibi ne, amma talakawa 2.5-inch SSD na iya biyan bukatun aikace-aikacen yau da kullun na yawancin masu amfani, 500MB/s ko haka karantawa da rubuta saurin ya isa.
