Ungayihlula njani i-SATA 2 kwi-SATA 3?
Ukuqonda Ukubaluleka Kwemigangatho Eyahlukileyo Yonxibelelwano
Xa udibanisa ikhompyutha, uphucula i-hard drive, okanye ulungisa iingxaki zokusebenza, kubalulekile ukwahlula ngokuchanekileyo phakathi kwe-SATA 2 (SATA II) kunye ne-SATA 3 (SATA III). Nangona ezi zizukulwana zimbini ze-interfaces zifana, umahluko wazo wokusebenza ubalulekile. Eli nqaku liza kukunika iindlela ezininzi ezisebenzayo zokukunceda ukwahlula ngokulula, kwaye likhankanye neminye imigangatho ye-interface ephezulu, efanaI-SAS SFF-8654 4I 38Pkunye nezinye iinkcukacha zobungcali.
I. Isishwankathelo esifutshane seThiyori: Umahluko oPhambili phakathi kweSATA 2 kunye neSATA 3
Ngaphambi kokuba senze umahluko, masiqonde iiparameter ezisisiseko:
I-SATA 2: Isantya esiphezulu sokudlulisa idatha yi-3 Gbps (malunga ne-300 MB/s), eyasungulwa ngo-2004.
I-SATA 3: Isantya esiphezulu sokudlulisa idatha yi-6 Gbps (malunga ne-600 MB/s), eyasungulwa ngo-2008.
Zombini ii-interfaces zinembonakalo efanayo, kodwa ziyahambelana (izixhobo ze-SATA 3 zingasetyenziswa kwii-interfaces ze-SATA 2, kodwa isantya silinganiselwe).
Kubalulekile ukuqaphela ukuba kwiindawo zokugcina izinto zobungcali nezeshishini, imigangatho yojongano yahlukile ngakumbi. Umzekelo,I-SAS SFF-8654 4I 38Pyinkcazo ye-interface esetyenziswa kwiinkqubo zokugcina ezisebenza kakhulu, ebonelela nge-bandwidth ephezulu kunye nokuthembeka kune-SATA yesiqhelo. Ukongeza,I-SFF 8654 4I ukuya kwi-U.2iiadaptha zivumela ii-U.2 NVMe solid-state drives ukuba ziqhagamshele kwiinkqubo ezixhasa i-I-SAS SFF-8654 4I 38Pujongano, oluqhelekile kwizisombululo zokugcina izinto ezikwinqanaba leshishini. Okwangoku, i-I-4X SFF 8482i-interface ikwayindlela eqhelekileyo ye-SAS interface esetyenziselwa ukuqhagamshela ii-hard drive ezininzi.
II. Iindlela Ezintlanu Zokwahlula Ezisebenzayo
1. Jonga iilebheli kwiMotherboard okanye kwiHard Drive
Ii-interfaces ze-SATA zebhodi yomama: Uninzi lwee-motherboards zineelebheli kufutshane nee-interfaces. Iilebheli eziqhelekileyo ziquka:
SATA 3: Isenokuphawulwa njenge "SATA 6G", "SATA 6Gb/s", okanye "SATA III".
SATA 2: Isenokuphawulwa njenge "SATA 3G", "SATA 3Gb/s", okanye "SATA II".
Iilebhile ze-Hard drive: Ii-SATA solid-state drives okanye ii-mechanical hard drives zihlala zine-interface version ebhalwe kwiilebhile zazo.
Xa usebenza nezixhobo zokugcina izinto ezikwinqanaba leshishini, ungadibana neendlela zokunxibelelana zobungcali ezifanaI-SAS SFF-8654 4I 38PEzi ndawo zokunxibelelana zihlala zisetyenziswa kwiinkqubo zokugcina iiseva ezisebenza kakuhle kwaye zibonelela ngesantya esidlula kakhulu eso sonxibelelwano oluqhelekileyo lwe-SATA. Ukuba ufuna ukuqhagamshela izixhobo ze-U.2 kwiinkqubo ezinjalo,I-SFF 8654 4I ukuya kwi-U.2iiadaptha ziba luncedo kakhulu. Okwangoku, iinkqubo ze-SAS ezindala zingasebenzisaI-4X SFF 8482ii-interfaces zokuqhagamshela kwii-backplanes ze-hard drive.
2. Yahlula ngombala (Ayisiyiyo imigangatho epheleleyo)
Abavelisi abaninzi bebhodi yomama basebenzisa ikhowudi yombala:
Ii-interface ze-SATA 3: Zihlala ziluhlaza okwesibhakabhaka, ezimhlophe, okanye zimnyama.
Ii-interface ze-SATA 2: Zihlala zimnyama, zingwevu, okanye zimthubi.
Nangona kunjalo, umbala awungomgangatho oqhelekileyo (umzekelo, i-ASUS idla ngokusebenzisa oluhlaza okwesibhakabhaka kwi-SATA 3, ngelixa i-Gigabyte ingasebenzisa omhlophe). Kucetyiswa ukudibanisa ezinye iindlela zokuqinisekisa.
Ngokwahlukileyo koko, iindlela zokunxibelelana zobungcali ezifanaI-SAS SFF-8654 4I 38PNgokuqhelekileyo zineempawu ezibonakalayo ezicacileyo ngakumbi.I-SFF 8654 4I ukuya kwi-U.2iiadaptha nazo zineempawu ezithile ezibonakalayo ezenza kube lula ukuzibona.I-4X SFF 8482Kwelinye icala, ujongano lubanzi olusetyenziswa rhoqo ekwandiseni i-SAS.
3. Jonga incwadi yemiyalelo yezixhobo zekhompyutha
Incwadi yemiyalelo yebhodi yomama: Eyona ndlela inokuthenjwa. Icandelo elithi "Storage Interface" okanye "Specification" liza kudwelisa ngokucacileyo uhlobo kunye nendawo ye-SATA interface nganye.
Incwadi yesandla yeHard drive: Iya kubonisa uhlobo lweSATA oluxhaswayo.
Kwizixhobo zekhompyutha ezikumgangatho weshishini, le ncwadi yemiyalelo iza kubonelela ngenkcazo eneenkcukacha zeenkcukacha kunye nokusetyenziswa kwazo.I-SAS SFF-8654 4I 38Pujongano. Ukuba ufuna ukusebenzisaI-SFF 8654 4I ukuya kwi-U.2kwisisombululo seadaptha, le ncwadi iya kubonelela ngezikhokelo zoqwalaselo ezifanelekileyo. Ngokufanayo, izixhobo ezixhasa i-I-4X SFF 8482ujongano luya kumakishwa ngokucacileyo kuxwebhu.
4. Sebenzisa ukufunyanwa kwesoftware
Izixhobo ezifana neCrystalDiskInfo kunye neHWiNFO: Zingabona inguqulelo yeSATA exhaswa yi-hard drive (eboniswa njenge "Transfer Mode").
Qaphela: Ukufunyanwa kwesoftware kubonisa amandla e-hard drive, kungekhona inguqulelo ye-motherboard interface. Ukuba i-hard drive ixhasa i-SATA 3 kodwa isebenza kwi-SATA 2 mode, oko kunokubonisa ukuba i-motherboard interface yi-SATA 2.
Kwiindawo zokunxibelelana zobungcali ezifanaI-SAS SFF-8654 4I 38P, isoftware yolawulo ethile inokufuneka ukuze kuchongwe kwaye kumiselwe. Imeko yeI-SFF 8654 4I ukuya kwi-U.2iadaptha ingafunyanwa ngezi zixhobo. Izixhobo eziqhagamshelwe kwiI-4X SFF 8482ujongano ludla ngokufuna ukujongwa kujongano lolawulo lwekhadi le-RAID.
5. Jonga ii-interface pins (indlela ephucukileyo)
I-interface ye-SATA ineephini ezisi-7 ngaphakathi, kodwa inguqulelo ayinakwahlulwa ngokuthe ngqo kwimbonakalo. Ukuba iimeko ziyavuma, ungabhekisa kwiinombolo zesikrini sesilika kwi-PCB yebhodi yomama (ezifana ne-SATA3_0, i-SATA2_3, njl.njl.).
Ngokwahlukileyo koko,I-SAS SFF-8654 4I 38Pujongano luneephini ezingama-38, eziyinxalenye yegama lalo.I-SFF 8654 4I ukuya kwi-U.2iadaptha kufuneka idibanise ezi pini ngokuchanekileyo.I-4X SFF 8482ujongano luneephini ezingaphezulu kwaye luxhasa ukuhanjiswa kwedatha yeendlela ezine.
III. Ukuqinisekiswa kokusebenza ngovavanyo lokwenyani
Ukuba sele uyiqhagamshele i-hard drive, ungagweba ngokungathanga ngqo ngovavanyo lwesantya:
Sebenzisa iCrystalDiskMark ukuvavanya isantya sokufunda nokubhala esiqhubekayo.
Ukuba isantya singaphantsi kwe-250-300 MB/s rhoqo, isenokuba isebenza kwimo ye-SATA 2 (nokuba i-hard drive ixhasa i-SATA 3).
Ukuba isantya sidlula i-500 MB/s, kusenokwenzeka ukuba isebenza kwimowudi ye-SATA 3.
Xa usebenzisaI-SAS SFF-8654 4I 38Pujongano, uvavanyo lokusebenza luya kubonisa isantya esiphezulu kuba luxhasa i-bandwidth ephezulu. Ii-hard drive ze-NVMe ziqhagamshelwe nge-I-SFF 8654 4I ukuya kwi-U.2iadaptha inokusebenzisa ngokupheleleyo amandla ayo okusebenza. Ngokufanayo, i-I-4X SFF 8482ujongano lunokubonelela nge-bandwidth ephezulu ehlanganisiweyo kune-SATA yesiteshi esinye.
Amanqaku e-IV.
Impembelelo yokusetyenziswa okuxutyiweyo: Ukuqhagamshela i-hard drive ye-SATA 3 kwi-interface ye-SATA 2 kuya kuyithintela ukusebenza (ukuhla ukuya kwinqanaba le-SATA 2), kodwa akuyi kubakho ngxaki zokuhambelana.
Umatshini weLaptop okanye uphawu: Indawo yangaphakathi incinci. Kucetyiswa ukuba ubhekisele ngqo kumaxwebhu asemthethweni eenkcukacha okanye izikhokelo zokuqhaqha.
Iintambo ze-SATA: Iintambo ze-SATA 3 zisebenza ngcono ekukhuseleni, kodwa ukuzixuba akudli ngokuchaphazela ukuqatshelwa (kunokuchaphazela uzinzo kwiindawo ezinesantya esiphezulu).
Kwimeko yeshishini, ukumisela ngokuchanekileyoI-SAS SFF-8654 4I 38Pujongano lubaluleke kakhulu. Xa usebenzisaI-SFF 8654 4I ukuya kwi-U.2iadaptha, kuyimfuneko ukuqinisekisa ukuba i-firmware kunye nomqhubi ziyahambelana.I-4X SFF 8482ujongano, ulawulo olufanelekileyo lwentambo lubalulekile ukuze isignali ihlale ithembekile.
V. Isishwankathelo kunye neeNgcebiso
Beka phambili ukujonga iileyibhile kunye nemiyalelo - eyona ichanekileyo nethembekileyo.
Hlanganisa ukufunyanwa kombala kunye nesoftware - ukuqinisekiswa okunqamlezileyo.
Ukuba kuyimfuneko, yenza uvavanyo lwesantya - qinisekisa indlela yokusebenza yokwenyani.
Ukwahlula ngokuchanekileyo iinguqulelo ze-SATA kunokukunceda udibanise ngokufanelekileyo i-hardware kwaye usebenzise ngokupheleleyo ukusebenza kwezixhobo zokugcina. Xa uphucula, kucetyiswa ukuqhagamshela ii-solid-state drives ezinesantya esiphezulu (ezifana nee-SSD) kwi-SATA 3 interface, kwaye ii-hard drives zoomatshini zinokuqhagamshelwa kwi-SATA 2 interface ukuze kugcinwe izixhobo ze-interface ezinesantya esiphezulu.
Kubasebenzisi abaziingcali abafuna ukusebenza okuphezulu, ukuqonda imigangatho yojongano efanaI-SAS SFF-8654 4I 38Pixabiseke kakhulu.I-SFF 8654 4I ukuya kwi-U.2Isisombululo sinika iindlela zonxibelelwano eziguquguqukayo zokugcina i-NVMe. Okwangoku, nangona kunjaloI-4X SFF 8482ngumgangatho omdala, usabalulekile kwiinkqubo ezininzi ezikhoyo. Nokuba yeyiphi na i-interface esetyenziswayo, ukuchongwa ngokuchanekileyo kunye noqwalaselo zizinto ezibalulekileyo ekuqinisekiseni ukusebenza kakuhle.
