Indlela I-Updated Version ye-SATA iya kuwandisa i-PC Speeds
I-SATA okanye i-Serial ATA ibe yimpumelelo enkulu xa kuziwa ekugcinweni kwekhompyutha. I-standadization kwi-interface ivumela ukufakwa lula kunye nokuhambelana phakathi kweekhompyutha kunye nezixhobo zokugcina. Ingxaki kukuba ukwakhiwa kwezonxibelelwano ezixhaswayo kuye kwafikelela kwimida yayo kunye nemimandla emininzi eqhutywe yimoya ekhishwe yinkqubo yesikhombiselwano kune-drive. Ngenxa yoko, imigangatho emitsha yoqhagamshelwano phakathi kweekhomputha kunye nokugcina izithuthi kufuneka iphuhliswe. Yilapho i-SATA Express ibonisa khona inqanaba lokugcwalisa i-gap yentsebenzo.
I-SATA okanye iPC-Express Express
Iinkcukacha ezikhoyo ze-SATA 3.0 zilinganiselwe kwi-bandwidth eyi-6.0 ye-Gbps eguqulela kwi-750MB / s. Ngoku ngokugqithiseleyo kwintsebenziswano kunye nento yonke, kuthetha ukuba ukusebenza okusebenzayo kwaphela kuphela kwi-600MB / s kuphela. Uninzi lwezizukulwana ezikhoyo zogxininiso olusisigxina luye lwafikelela kweli nqanaba kwaye lifuna uhlobo oluthile lwenxibelelwano olukhawulezayo. I-SATA 3.2 inkcazo ebizwa ngokuba yi-SATA Expess iyinxalenye yokuvelisa indlela entsha yokunxibelelana phakathi kweekhomputha kunye nezixhobo ngokuvumela izixhobo ukuba zikhethe ukuba zifuna ukusebenzisa indlela ekhoyo ye-SATA, ukuqinisekisa ukuhambelana nokubuyela kumashishini asekudala, okanye ukusebenzisa i- PCI esheshayo. -Ibhasi yokuqhuba .
Ibhasi ye-PCI-Express sele isetyenziselwa ukuthetha phakathi kwe-CPU kunye nezixhobo zepheripheral ezifana namakhadi eemifanekiso, izixhobo zokunxibelelana, ii-USB zangaphandle, njl. Ngaphandle kwemiqathango ekhoyo ye-PCI-Express 3.0, enye indlela ye-PCI-Express inokusingatha ukuya kwi-1GB / s ukwenza okukhawulezileyo kunobonakaliso obukhoyo be-SATA. Yiloo nto enye i-PCI-Express lane inokufezekisa kodwa amacebo angasebenzisa iindlela ezininzi. Ngokuhambelana neenkcukacha ze-SATA Express, i-drive ene-interface entsha ingasebenzisa iindlela ezimbini ze-PCI-Express (ngokuphindaphindiweyo ziphinde zenziwe njenge-x2) zibe ne-bandwidth ye-2GB / s eyenza ukuba ibe malunga nesithathu kwisantya se-SATA 3.0.
Umxhumo omtsha we-SATA Express
Ngoku i-interface entsha ifuna ikhonkco entsha. Ingabonakala ngendlela efanayo ngoba umnxibelelwano udibanisa idibaniselwano ezimbini ze-SATA kunye nomnxibelelwana wesithathu omncinci ojongene nophuhliso lwe-PCI-Express. Abaxhamli ababini be-SATA ngokwenene basebenze ngokupheleleyo kwii-SATA 3.0 zokungena. Oku kuthetha ukuba inxibelelwano enye ye-SATA Express kwikhompyutyana inokuxhasa ii-port SATA ezidala. Umba ufika xa ufuna ukucoca i-drive ye-SATA Express esekelwe kwisixhobo sokuxhuma. Zonke iifowuni ze-SATA Express ziza kusebenzisa ububanzi obupheleleyo nokuba ngaba i-drive isekelwe kumnxibelelwano omdala we-SATA okanye iPCI-Express entsha. Ngoko, enye i-SATA Express ingakwazi ukuqhuba ii-SATA ezimbini okanye enye ye-SATA Express drive.
Ngoko kutheni i-drive ye-SATA Express esekelwe yi-PCI-Express isebenzisa kuphela isixhumi esinye sesithathu kunezichweba ze-SATA ezimbini? Oku kuhambelana nento yokuba i-drive ye-SATA Express esebenzayo ingasebenzisa i-teknoloji, ngoko kufuneka ibe ne-interface kunye nabo bobabini. Ukongeza kule nto, amanxweme amaninzi e-SATA axhunyiwe kwi-PCI-Express lane yokuthetha nomprojekthi. Ngokusebenzisa i-PCI-Express interace ngokukodwa nge-drive ye-SATA Express, uyanqumla ngokukhawuleza unxibelelwano kwizibini ezimbini ze-SATA ezixhomekeke kuloo nxibelelwano.
Umyalelo wokuLawulwa koLwazi
I-SATA iyindlela efanelekileyo yokunxibelelana kwedatha phakathi kwesixhobo kunye ne-CPU kwikhompyutha. Ukongezelela kuloluhlu, kukho umgca womyalelo oqhuba phezulu kule nto ukuthumela imiyalelo ekufuneka ibhalelwe kwaye ifunde kwi-drive yokugcina. Iminyaka, le nto ilandelwe ngu-AHCI (Interface Advanced Host Controller Interface). Oku kuye kwachaneka kangangokuthi kubhalwe ngokubhaliweyo kuyo yonke inkqubo yokusebenza njengamanje kwimarike. Oku kwenza ukuba i-SATA idlulise iplagi kunye nokudlala. Akukho mqhubi ofunekayo. Nangona iteknoloji isebenze kakuhle ngeteknoloji eyadala ngokukhawuleza njengamatshini asebenzayo kunye ne-USB flash drives, iyakubamba i-SSD ngokukhawuleza. Ingxaki kukuba ngelixa umgca we-AHCI umyalelo ungabamba imiyalelo engama-32 kumgca, ungasenza kuphela umyalelo omnye ngexesha kuba kukho umgca omnye.
Le yilapho umyalelo we-NVMe (Non-Volatile Memory Memory) ungena kuwo. Unomlinganiselo wee-65,536 umgca wolawulo ngamnye kunye nokukwazi ukubamba imiyalelo engama-65,536 ngomgca. Ngokuchanekileyo, oku kuvumela ukulandelelana okufanayo kwemithetho yokugcina kwi-drive. Oku akuncedisi kwi-drive enzima njengoko kusele ngokukhawuleza kumyalelo owodwa ngenxa yeentloko ze-drive kodwa ukuba i-state eqhubayo imitshini kunye ne-memory memps yayo iyakwazi ukukhulisa ngokugqithiseleyo umda wabo wendlela ngokubhala imiyalelo emininzi kwii-chip kunye neeseli ezahlukeneyo ngokufanayo. .
Oku kunokuzwakala kukukhulu kodwa kukho ingxaki ethile. Le yile teknoloji entsha kwaye ngenxa yoko ayinakwakhiwa kwiinkqubo ezininzi ezikhoyo kwimarike. Enyanisweni, uninzi luya kufuna ukuba ngabaqhubi abongezelelweyo bafake kuwo ukuze i-drivers isebenzise iteknoloji entsha ye-NVMe. Oku kuthetha ukuthunyelwa kweyona ndlela yokukhawuleza yokuqhuba i-SATA Express i-drivers ingathatha ixesha njengoko isofthiwe ikhule ngokufana ne-introduction ye-AHCI. Ngombulelo, i-SATA Express ivumela ii-drive ukuba zisebenzise ezinye zeendlela ezimbini ukuze usebenzise i-teknoloji entsha ngoku ngabaqhubi be-AHCI kwaye unokufudukela kumgangatho omtsha we-NVMe kamva ukwenzela ukuphucula ukusebenza, nokuba mhlawumbi ufuna ukuba i-drive ibuyiselwe kwakhona.
Ezinye izinto ezifakwe nge-SATA Express ngeSATA 3.2 Iinkcazo
Ngoku ke iinkcukacha ezintsha ze-SATA zongeza ngaphezu kweendlela ezintsha zokunxibelelana kunye nomxhasi. Uninzi lwazo lujoliswe kwiikhomputha ze-cellular kodwa ziyakwanceda nezinye iikhomputha ezingekhoyo. Uphawu oluphawulekayo lokugcina amandla yindlela entsha ye-DevSleep. Le ndlela yindlela entsha yamandla evumela ukuba iinkqubo ekugcinweni zivalwe ngokupheleleyo kwaye zinciphise amandla ekudwebeni ngexesha lokulala. Oku kufuneka kukuncede ukuphucula amaxesha asebenzayo kwiiptops ezizodwa kuquka ii- Ultrabooks ezenziwe nge-SSD kunye nokusetyenziswa kwamandla aphantsi.
Abasebenzisi be- SSHD (i-solid state hybrid drives) nabo baya kuzuza kwimilinganiselo emitsha njengoko bafaka kwi-set set of optimisation. Kwiindlela ezikhoyo ze-SATA zangoku, umlawuli womqhubi uya kugqiba ukuba yiziphi izinto ezifunekayo kwaye akufanele zigcinwe kwi-cache esekelwe kwizinto ezizibonayo zizayo. Ngesakhiwo esitsha, inkqubo yokusebenza ingabhekisela kumlawuli we-drive ukuba izinto ezifunekayo zibambe kwi-cache eyanciphisa inani eliphezulu kwi-controller drive kunye nokuphucula ukusebenza.
Ekugqibeleni, kukho umsebenzi wokusetyenziswa kunye nee- setup ze- RAID . Enye yeenjongo ze-RAID yinto yokulungiswa kwedata. Xa kwenzeka ukungaphumeleli kwe-drive, i-drive iya kutshintshwa kwaye ke idatha iya kuphinda ikhiwe kwi-data checksum. Ngokwenene, bakhele inkqubo entsha kumgangatho we-SATA 3.2 onokukunceda ukuphucula inkqubo yokwakhiwa ngokuqaphela ukuba yeyiphi idilesi eyonakalisiwe nxamnye noko kungenjalo.
Ukuphunyezwa kunye nokuba kutheni kungabikho
I-SATA Express ibinomgangatho oseburhulumenteni ukususela ekupheleni kuka-2013 kodwa ayizange iqalise ukwenza iindlela zayo kwiinkqubo zekhompyutheni kude kukhululwe i-Intel H97 / Z97 i-chipsets entwasahlobo ka-2014. Ngaphandle kwamabhodi amabhinqa ngoku ene-interface entsha, kukho akukho mqhubi ngexesha lokuqaliswa okukwazi ukusebenzisa umbane omtsha. Oku kwenzeka ngenxa yemicimbi ejikeleze inkxaso yenkqubo yokusebenza yomyalelo omtsha wokumisela ukuba usebenzise ngokugcwele iSATA Express. Ubuncinane ukuphunyezwa kwangoku kuvumela ii-SATA Express izixhumo ukuba zisetyenziswe ngeenjini ezikhoyo ze-SATA. Oku kufuneka kukuncedise ukunciphisa ukuphunyezwa kwale nto eyenzekayo ukuthenga iteknoloji ngoku xa i-drivers zifumaneka.
Isizathu sokuba ukhonxibelelwano alubambanga ngobuxoki bokwenene kunye ne-interface iM.2 . Le nto isetyenziselwa kuphela imimoya eqinileyo yokusebenzisa ifom yefom yefowuni kunye neenkqubo ze desktop. Iimoto ezinzima zihlala zinzima kunamazinga eSATA. I-M.2 ine-flexibility more because it does not depend on the drives larger but it can also use four PI-Express lanes, which means a drivers faster than the two paths of SATA Express. Kule ngxaki, abathengi abanakuze babone i-SATA Express yamukelwa.
