Indlela I-Updated Version ye-SATA izokwandisa ukuhamba kwe-PC
I-SATA noma i-Serial ATA ibe yimpumelelo enkulu uma kuziwa ekugcineni kwesitoreji. I-standadization ku-interface ivumela ukufakwa okulula nokuhambisana phakathi kwamakhompyutha namadivayisi wokugcina. Inkinga yukuthi ukuklanywa kokuxhumana okufakiwe kufinyelele ekukhawulweni kwayo kanye nokushayela okunamandla okunamandla okukhishwa ngokusebenza kwesikhombimsebenzisi kunokuba idrayivu. Ngenxa yalokhu, amazinga amasha okuxhumana phakathi kwamakhompyutha kanye nokugcina amarekhodi adingekayo ukuze athuthukiswe. Yilapho i-SATA Express ingena khona ukugcwalisa igebe lokusebenza.
Ukuxhumana kwe-SATA noma i-PCI-Express
Izincazelo ezikhona ze-SATA 3.0 zilinganiselwe ku-6.0Gbps bandwidth ehamba cishe engama-750MB / s. Manje nge-overhead yesikhombikubona nabo bonke, kusho ukuthi ukusebenza okusebenzayo kwavinjelwe ku-600MB / s kuphela. Isizukulwane esiningi samanje sokushayela isimo esiqinile sifike ekugcineni kulo mkhawulo futhi sidinga uhlobo oluthile lokuxhumana okusheshayo. Ukucaciswa kwe-SATA 3.2 okuyinto i-SATA Expess iyingxenye yokuletha izindlela ezintsha zokuxhumana phakathi kwekhompyutha namadivayisi ngokuvumela amadivaysi ukuba akhethe ukuthi afuna ukusebenzisa indlela ekhona ye-SATA, ukuqinisekisa ukuhambisana nokubuyela emuva kumadivayisi amadala, noma ukusebenzisa i- PCI esheshayo - Ibhasi lokuhlola .
Ibhasi le-PCI-Express liye lisetshenziselwa ukuxhumana phakathi kwama-CPU namadivaysi omsakazo njengamakhadi ehluzo, ukuxhumeka kwenethiwekhi, amathrekhi e-USB, njll Ngaphansi kwamazinga we-PCI-Express 3.0 amanje, umzila owodwa we-PCI-Express ungakwazi ukusingatha ku-1GB / s ukwenza ngokushesha kunesikhombimsebenzisi se-SATA samanje. Yilokho indlela eyodwa ye-PCI-Express engayifinyelela kodwa amadivayisi angasebenzisa imizila eminingi. Ngokusho kwemininingwane ye-SATA Express, i-drive ene-interface esibonakalayo ingasebenzisa imigqa emibili ye-PCI-Express (ngokuvamile ibuyelelwe njenge-x2) ukuze ibe nomkhawulokudonsa ongase ube ngu-2GB / s okwenza isisindo se-SATA 3.0 esedlule.
Isixhumi se-New SATA Express
Manje isikhombimsebenzisi esisha sidinga isixhumi esisha. Kungase kubonakale ngendlela efanayo ngoba isixhumi sihlanganisa ngempela izixhumi ezimbili ze-SATA nedivaysi yesithathu encane ephathelene nokuxhumana okusekelwe yi-PCI-Express. Izixhumi ezimbili ze-SATA empeleni ziyi-SATA 3.0 zokusebenza ezigcwele ngokugcwele. Lokhu kusho ukuthi ifoni eyodwa ye-SATA Express kukhompyutha ingase isekele amathrekhi amabili ase-SATA amadala. Inkinga ifika lapho ufuna ukuvula i-drive entsha esekelwe i-SATA Express ibe yikhox. Zonke izixhumi ze-SATA Express zizosebenzisa ububanzi obugcwele noma ngabe idrayivu isekelwe ekuthunjweni okudala kwe-SATA noma i-PCI-Express entsha. Ngakho-ke, enye i-SATA Express ingakwazi ukubhekana namashayela amabili we-SATA noma i-drive eyodwa ye-SATA Express.
Ngakho kungani i-drive ye-SATA Express esekelwe e-PCI-Express isebenzisa kuphela isixhumi esisodwa sodwa kunezingxenyana ezimbili ze-SATA? Lokhu kuhlobene nokuthi i-drive esekelwe i-SATA Express ingasebenzisa noma ubuchwepheshe, ngakho-ke kudinga ukuthi ibe nokukhonjiswa kokubili kokubili. Ngaphezu kwalokhu, amathrekhi amaningi we-SATA axhunyaniswa nomzila we-PCI-Express wokuxhumana nomseshi. Ngokusebenzisa ibanga le-PCI-Express ngokuqondile nedrayivu ye-SATA Express, uyanqamula ngokuphumelelayo ukuxhumana kumachwebeni amabili we-SATA axhunywe kuleyo interface noma yikuphi.
Lawula Ukulinganiselwa Kwangaphakathi
I-SATA iyindlela engcono yokuxhumana idatha phakathi kwedivayisi ne-CPU kwikhompyutha. Ngaphezu kwalolu ungqimba, kukhona ukulayishwa komyalo ogijima phezulu kwalokhu ukuthumela imiyalo kulokho okumele kubhaliswe futhi kufundwe kusukela ku-drive yokugcina. Sekuyiminyaka, lokhu kuhanjiswe yi-AHCI (Interface Advanced Host Controller Interface). Lokhu kuye kwaba kuhle kangangokuthi kubhalwe phansi kuzo zonke izinhlelo zokusebenza okwamanje emakethe. Lokhu ngokuphumelelayo kwenza i-plug kanye nokudlala kwe-SATA imoto. Awekho amashayeli engeziwe adingekayo. Ngenkathi ubuchwepheshe busebenza kahle nobuchwepheshe obuthakathaka obudala njengamashayela asebenzayo kanye ne-USB flash drives, ligcina ngempela ama-SSD asheshayo. Inkinga yukuthi ngenkathi umyalo we-AHCI umyalo ungabamba imiyalo engu-32 emgqeni, usaqhubeka nje ukucubungula umyalo owodwa ngesikhathi ngoba kukhona umgca owodwa kuphela.
Yilapho ukusethwa komyalo we-NVMe (Non-Volatile Memory Express) kufaka khona. Kuhlanganisa umthamo wezingqimba zomyalo ezingu-65,536 ngamunye onamandla okubamba imiyalo engu-65,536 ngomugqa. Ngokuphumelelayo, lokhu kuvumela ukucubungula okufanayo kwemiyalelo yokugcina ku-drive. Lokhu akuzuzisi ku-hard drive njengoba kusasebenza ngokulinganayo kumyalo owodwa ngenxa yamakhanda okushayela kodwa ukushayela kombuso okuqinile ne-multiple memory chips kungakwazi ukukhulisa umkhawulokudonsa wabo ngokubhala imiyalo eminingi kuma-chips ahlukene namaseli ngesikhathi esisodwa .
Lokhu kungase kuzwakale kuhle kepha kunenkinga encane. Lokhu ubuchwepheshe obusha futhi ngenxa yalokho akukwakhiwa kuzo eziningi zezinhlelo zokusebenza ezikhona emakethe. Eqinisweni, iningi lizodinga ukuba namanye amashayeli afakwe kuwo ukuze amashayeli angasebenzisa ubuchwepheshe obusha be-NVMe. Lokhu kusho ukuthi ukuthunyelwa kokusebenza okusheshayo kokushayela kwe-SATA Express kungathatha isikhashana njengoba isofthiwe kufanele ikhule ngokufanayo nesingeniso sokuqala se-AHCI. Ngokujabulisayo, i-SATA Express ivumela ukushayela ukusebenzisa noma iyiphi yalezi zindlela ezimbili ukuze usasebenzisa ubuchwepheshe obusha manje nabashayeli be-AHCI futhi ungathuthela emazingeni amasha we-NVMe kamuva ekusebenzeni okuthuthukisiwe, noma kungenzeka ukuthi idinga ukuguqulwa kabusha.
Ezinye izinto ezifakiwe nge-SATA Express nge-SATA 3.2 Specs
Manje izimpawu ezintsha ze-SATA zengeze ngaphezu kwezindlela ezintsha zokuxhumana nomxhuma. Iningi lazo libhekiswe kumakhompiyutha aselula kodwa futhi zingazuza namanye amakhompyutha angewona amakhalekhukhwini. Isici esivelele kakhulu sokugcina amandla yindlela entsha ye-DevSleep. Lokhu ngokuyisisekelo imodi yamandla emisha evumela ukuthi amasistimu esitoreji aphelelwe ngokuphelele ngakho ukunciphisa ukudweba kwamandla uma kumodi yokulala. Lokhu kufanele kusize ukuthuthukisa izikhathi ezihambayo ze-laptops ezikhethekile kuhlanganise ne- Ultrabooks ezenzelwe ezungeze ama-SSD nokusetshenziswa kwamandla aphansi.
Abasebenzisi be- SSHD (ama-driver state hybrid drives) nabo bazozuza emazingeni amasha njengoba abeke esimisweni esisha sokulungiselelwa. Emisebenzini yamanje ye-SATA, isilawuli se-driver sinquma ukuthi yiziphi izinto okufanele zifanele futhi akufanele zigcinwe ngokusekelwe kulokho okubonayo okulethweyo. Ngesakhiwo esisha, isistimu yokusebenza ingasho ngokucacile umlawuli wedrayivu okudingeka ukuthi ubambe kulokhu okugcinwe khona okunciphisa inani eliphezulu phezu kwesilawuli sedrayivu nokuthuthukisa ukusebenza.
Okokugcina, kunomsebenzi wokusetshenziswa ngama-setups drive drive. Enye yezinhloso ze-RAID kungenxa yokubuyiswa kwedatha. Uma kwenzeka ukuhluleka kokushayela, idrayivu ingashintshwa bese idatha ingakhiwa kabusha kusukela ku-data checksum. Empeleni, bakhele inqubo entsha kumazinga we-SATA 3.2 angasiza ekuthuthukiseni inqubo yokwakha kabusha ngokuqaphela ukuthi iyiphi idatha eyonakalisiwe nalokho okungenjalo.
Ukuqaliswa nokuthi kungani kungakabanjwa
I-SATA Express ibe yindinganiso esemthethweni kusukela ekupheleni kuka-2013 kodwa ayizange iqale ukwenza izindlela zayo zibe yizinhlelo zekhompyutha kuze kukhululwe i-chipsets ye-Intel H97 / Z97 entwasahlobo ka-2014. Ngisho namabhodi wamabhodi manje ane-interface esibonakalayo, kukhona akukho ukushayela ngesikhathi sokuqaliswa okukwazi ukusebenzisa isikhombimsebenzisi esisha. Lokhu kungenzeka ngenxa yezimpikiswano ezizungezile ukusekelwa kwesistimu yokusebenza yomyalo omusha we-command ukuze usebenzise ngokugcwele i-SATA Express. Okungenani ukuqaliswa kwamanje kuvumela ukuxhuma kwe-SATA Express ukuthi kusetshenziswe ngamashayela e-SATA akhona. Lokhu kufanele kusize ukunciphisa ukuqaliswa kwalabo okwenzekayo ukuthenga ubuchwepheshe manje uma kuqhutshwa amashayela.
Isizathu sokuthi isikhombimsebenzisi asizange sibambe amanga ngempela nge-interface iM.2 . Lokhu kusetshenziselwa kuphela ukushayela kwezwe okuqinile okusebenzisa isici sefomu encane esetshenziswa kuma-laptop computer kepha futhi nezinhlelo zedeskithophu. Ukushayela okunamandla kusenesikhathi esinzima kunamazinga we-SATA. I-M.2 ine-flexibility more ngoba ayithembeli kumashayeli amakhulu kodwa ingasebenzisa futhi imizila emine ye-PCI-Express okusho ukuthi kuhamba ngokushesha kunezinkomba ezimbili ze-SATA Express. Kuleli qophelo, abathengi bangase bangaboni ukuthi i-SATA Express yamukelwa kanjani.
