Kungenzeka kakhulu ukuthi Wake wezwa ngesixhumi se-SATA Express?. Eminyakeni edlule, ingxenye yesitoreji iguqukele ngokumangazayo, ikakhulukazi ngokuba khona kwama-SSD. Ngakho-ke, leli gama esilikhulumile laqala ukwaziwa phakathi kwabasebenzisi abaningi ohlelweni lokusebenza. Ngenkathi kunabasebenzisi abaningi abangazi kahle ukuthi kuyini.
Okulandelayo siyakutshela okuningi nge-SATA Express nesimo sayo samanje lobu buchwepheshe namuhla. Kusukela izinguquko eziningi ezenzekile ngalesi sikhathi zibe nomthelela ocacile kuso.
Kuyini iSATA Express
I-SATA Express iyi- isivinini esibonakalayo sokuxhuma okuncike kubuchwepheshe be-SATA (Serial ATA). Ixhasa amadivayisi alolu hlobo kanye ne-PCI Express. Kuyinto isikhombimsebenzisi esivame ukusazi njenge-SATAe, okungenzeka wake wasibona kwesinye isikhathi. Yize kubalulekile ukusho ukuthi akuyona into okufanele ididaniswe ne-eSATA. Lezi zokugcina zenzelwe amayunithi angaphandle. Ngakho-ke zehlukile.
I-SATA Express yafika emakethe ngo-2014 njenge-SATA 3.2, yigama abaningi abangase balazi ngalo. Kuza ngenhloso yokuhlinzeka amandla wokuxhasa amadivayisi we-PCIe. Kulokhu, lesi sixhumi esibonakalayo esisha besinamandla okufinyelela isivinini esingu-16 GB / s, esifana no-1,97 GB / s. Ngale ndlela, iphumelele kakhulu iSATA 3.0 kulokhu. Ukuthuthuka okubalulekile, ngakho-ke.
Ngenxa yalokhu, abaklami be-SATA bathole ukuphinda kabili isivinini kusixhumi esibonakalayo esiyisisekelo kubiza kakhulu, futhi nakho okuholele ekusetshenzisweni kwamandla indala kakhulu. Ngalesi sizathu, baphoqeleka ukuthi bafune ezinye izixazululo. Yilokhu abakuzuzile ngokuvumelanisa umthetho olandelwayo wokudlulisa idatha kusixhumi esibonakalayo esisha, ngokususelwa ku-PCI-Express. Ngakho-ke, isivinini esiphakeme siyatholakala, ngokunciphisa ukusetshenziswa kwamandla. Inhlanganisela oyifunayo kulokhu.
Kungakho i-SATA Express ingasebenza ne-AHCI (Advanced host Controller Interface) yokuxhumana, kodwa futhi ne I-interface enengqondo ye-NVMe. Lokhu kuyinto ekuvumela ukuthi uthole okuningi kumayunithi wesitoreji se-PCIe. Ngaphezu kwalokho, inesibopho sokunikeza ukuhambisana kumakhompyutha amadala ane-AHCI.
Izici ze-SATA Express
Ukugqama kweSATA Express yilokho ingaxhasa zombili i-PCI Express ne-SATA. Ngakho-ke kuyindlela eguquguqukayo kakhulu kulokhu mayelana nabasebenzisi. Lokhu kungenzeka ngenxa yokuxhumeka ngamabhasi we-PCI Express 2.0 kanye ne-3.0 noma ngamachweba we-SATA 3.0 axhumene nomunye ngesixhumi samandla.
Amadivayisi axhuma kusetshenziswa indlela yokuqala (i-PCIe) azoba nokuxhumana okuqondile phakathi kwebhodi lomama nedrayivu yokugcina. Ngale ndlela, asikho isidingo sokusebenzisa isendlalelo esingeziwe okwenza ngazo lezi zinqubo zokuxhuma zihambisane. Kuyinzuzo enkulu iSATA Express esinikeza yona. Kwenza le nqubo ibe lula kakhulu.
Yize inikeza ngezinzuzo ezithile ezicacile, kukhona nezinye izici ezingezinhle ku-SATA Express. Yize isinikeza ukusekelwa kwalezi zinqubo zombili, zombili kuphela ezingaxhunywa ngasikhathi sinye. Lokhu kusho ukuthi umsebenzisi oxhumanisa i-hard drive ye-SATA kwikhompyutha yakhe, uzobona ukuthi ikhompyutha isebenza kanjani naleyo ayixhumile, uma kuyi-PCIe kuphela enalokho futhi uma kuyi-SATA, kuphela nalokho.
Kungani iSATA Express ingasetshenziswa
Naphezu kwezinzuzo ezinakho, namuhla singakwazi bona ukuthi iSATA Express ayisetshenziswa kakhulu. Isizathu esikhulu ukuthi kukhona esinye isikhombimsebenzisi esintshontshe ukugqama, okuyi-M.2. Kuyisixhumi esibonakalayo esibonwe njengokungena esikhundleni, futhi lokho kancane kancane kuhlangabezana nalokhu okulindelwe.
Umehluko omkhulu ukuthi UM.2 akanakho ukulinganiselwa esikuthola esimweni seSATA Express. Ngalesi sizathu, iningi labakhiqizi likhetha le nketho namuhla.
