Momwe mungasiyanitsire SATA 2 ndi SATA 3?
Kumvetsetsa Kufunika kwa Miyezo Yosiyanasiyana ya Ma Interface
Mukamalumikiza kompyuta, kukonza hard drive, kapena kuthetsa mavuto a magwiridwe antchito, ndikofunikira kusiyanitsa bwino pakati pa ma interface a SATA 2 (SATA II) ndi SATA 3 (SATA III). Ngakhale mibadwo iwiri iyi ya ma interfaces ikuwoneka yofanana, kusiyana kwawo kwa magwiridwe antchito ndikofunikira. Nkhaniyi ikupatsani njira zingapo zothandiza kuti zikuthandizeni kuzisiyanitsa mosavuta, komanso kutchulanso miyezo ina yokhudzana ndi mawonekedwe apamwamba, mongaSAS SFF-8654 4I 38Pndi zina zofunikira pantchito.
I. Chidule Chachidule cha Chiphunzitso: Kusiyana Kwakukulu Pakati pa SATA 2 ndi SATA 3
Tisanapange kusiyana, tiyeni timvetse magawo oyambira:
SATA 2: Liwiro losamutsa lapamwamba kwambiri la chidziwitso ndi 3 Gbps (pafupifupi 300 MB/s), lomwe linayambitsidwa mu 2004.
SATA 3: Liwiro losamutsa lapamwamba kwambiri ndi 6 Gbps (pafupifupi 600 MB/s), lomwe linayambitsidwa mu 2008.
Ma interface onsewa ali ndi mawonekedwe ofanana, koma amagwirizana (zipangizo za SATA 3 zitha kugwiritsidwa ntchito pa ma interface a SATA 2, koma liwiro lake ndi lochepa).
Ndikofunikira kudziwa kuti m'magawo osungira zinthu a akatswiri komanso amakampani, miyezo yolumikizirana ndi yosiyana kwambiri. Mwachitsanzo,SAS SFF-8654 4I 38Pndi mawonekedwe ofunikira omwe amagwiritsidwa ntchito mu makina osungira zinthu apamwamba kwambiri, omwe amapereka bandwidth yokwera komanso kudalirika kuposa SATA yachikhalidwe. Kuphatikiza apo,SFF 8654 4I kupita ku U.2ma adapter amalola ma U.2 NVMe solid-state drives kulumikizana ndi makina omwe amathandiziraSAS SFF-8654 4I 38Pmawonekedwe, omwe amapezeka kwambiri m'njira zosungiramo zinthu pamlingo wamakampani. Pakadali pano, njira yachikhalidwe4X SFF 8482mawonekedwe ndi muyezo wamba wa mawonekedwe a SAS womwe umagwiritsidwa ntchito polumikiza ma hard drive angapo.
II. Njira Zisanu Zothandiza Zosiyanitsa
1. Chongani Zolemba pa Motherboard kapena Hard Drive
Ma interface a SATA a Motherboard: Maboard ambiri a mama ali ndi zilembo pafupi ndi ma interface. Zolemba zodziwika bwino ndi izi:
SATA 3: Ikhoza kulembedwa kuti "SATA 6G", "SATA 6Gb/s", kapena "SATA III".
SATA 2: Ikhoza kulembedwa "SATA 3G", "SATA 3Gb/s", kapena "SATA II".
Zolemba za Hard Drive: Ma SATA solid-state drives kapena ma mechanical hard drives nthawi zambiri amakhala ndi mawonekedwe owonekera pamalembo awo.
Mukamagwira ntchito ndi zipangizo zosungiramo zinthu zamakampani, mungakumane ndi malo ogwirira ntchito akatswiri mongaSAS SFF-8654 4I 38PMa interface awa nthawi zambiri amagwiritsidwa ntchito m'ma seva osungira omwe amagwira ntchito bwino kwambiri ndipo amapereka liwiro loposa la ma interface wamba a SATA. Ngati mukufuna kulumikiza zida za U.2 ku makina otere,SFF 8654 4I kupita ku U.2ma adapter amakhala othandiza kwambiri. Pakadali pano, makina akale a SAS angagwiritse ntchito4X SFF 8482ma interfaces olumikizira ku ma backplanes a hard drive.
2. Kusiyanitsa ndi Mtundu (Si Muyezo Wokwanira)
Opanga ma motherboard ambiri amagwiritsa ntchito mitundu yojambulira:
Ma interface a SATA 3: Nthawi zambiri amakhala abuluu, oyera, kapena akuda.
Ma interface a SATA 2: Nthawi zambiri amakhala akuda, imvi, kapena achikasu.
Komabe, mtundu si muyezo wamba (mwachitsanzo, ASUS nthawi zambiri imagwiritsa ntchito buluu pa SATA 3, pomwe Gigabyte ingagwiritse ntchito yoyera). Ndikofunikira kuphatikiza njira zina zotsimikizira.
Mosiyana ndi zimenezi, malo ogwirira ntchito akatswiri mongaSAS SFF-8654 4I 38Pnthawi zambiri amakhala ndi zizindikiro zomveka bwino.SFF 8654 4I kupita ku U.2Ma adapter alinso ndi mawonekedwe enieni omwe amawapangitsa kukhala osavuta kuwazindikira.4X SFF 8482Koma mawonekedwe ake ndi cholumikizira chachikulu chomwe chimagwiritsidwa ntchito pokulitsa SAS.
3. Yang'anani buku la malangizo a hardware
Buku la ma motherboard: Njira yodalirika kwambiri. Gawo la "Storage Interface" kapena "Specification" lidzalemba momveka bwino mtundu ndi malo a SATA interface iliyonse.
Buku la hard drive: Lidzasonyeza mtundu wa SATA womwe umathandizidwa.
Pa zipangizo zamagetsi zamakampani, bukuli lidzapereka tsatanetsatane wa zofunikira ndi momwe zimagwiritsidwira ntchitoSAS SFF-8654 4I 38Pmawonekedwe. Ngati mukufuna kugwiritsa ntchitoSFF 8654 4I kupita ku U.2njira ya adaputala, bukuli lidzaperekanso malangizo ogwirizana ndi kasinthidwe. Mofananamo, zipangizo zothandizira4X SFF 8482mawonekedwe adzalembedwa bwino mu zolembazo.
4. Gwiritsani ntchito kuzindikira mapulogalamu
Zida monga CrystalDiskInfo ndi HWiNFO: Zimatha kuzindikira mtundu wa SATA wothandizidwa ndi hard drive (yomwe imawonetsedwa ngati "Transfer Mode").
Dziwani: Kuzindikira mapulogalamu kumasonyeza mphamvu ya hard drive, osati mtundu wa mawonekedwe a motherboard. Ngati hard drive ikuthandizira SATA 3 koma ikugwira ntchito mu SATA 2 mode, zitha kusonyeza kuti mawonekedwe a motherboard ndi SATA 2.
Kwa ma interfaces aukadaulo mongaSAS SFF-8654 4I 38P, mapulogalamu enaake oyang'anira angafunike kuti azindikire ndi kukonza. Mkhalidwe waSFF 8654 4I kupita ku U.2adaputala ingathenso kupezeka kudzera mu zida izi. Zipangizo zolumikizidwa ku4X SFF 8482mawonekedwe nthawi zambiri amafunika kufufuzidwa mu mawonekedwe oyang'anira khadi la RAID.
5. Yang'anirani ma pin olumikizirana (njira yapamwamba)
Chida cha SATA chili ndi ma pin 7 mkati, koma mtunduwo sungasiyanitsidwe mwachindunji ndi mawonekedwe ake. Ngati zinthu zilola, mutha kuwona manambala a silk-screen pa PCB ya mamaboard (monga SATA3_0, SATA2_3, ndi zina zotero).
Mosiyana ndi zimenezi,SAS SFF-8654 4I 38Pmawonekedwe ake ali ndi ma pin 38, omwe ndi gawo la dzina lake.SFF 8654 4I kupita ku U.2adaputala iyenera kulumikiza mapini awa molondola.4X SFF 8482mawonekedwe ake ali ndi mapini ambiri ndipo amathandizira kutumiza deta ya njira zinayi.
III. Kutsimikizira magwiridwe antchito kudzera mu mayeso enieni
Ngati mwalumikiza kale hard drive, mutha kuweruza mwanjira ina kudzera mu kuyesa liwiro:
Gwiritsani ntchito CrystalDiskMark kuti muyese liwiro lowerenga ndi kulemba mosalekeza.
Ngati liwiro lake lili pansi pa 250-300 MB/s nthawi zonse, likhoza kukhala likuyenda mu SATA 2 mode (ngakhale hard drive ikuthandizira SATA 3).
Ngati liwiro likupitirira 500 MB/s, mwina likugwira ntchito mu SATA 3 mode.
Mukagwiritsa ntchitoSAS SFF-8654 4I 38Pmawonekedwe, mayeso a magwiridwe antchito adzawonetsa liwiro lalikulu chifukwa amathandizira bandwidth yapamwamba. Ma hard drive a NVMe olumikizidwa kudzera muSFF 8654 4I kupita ku U.2Adapta ikhoza kugwiritsa ntchito bwino mphamvu zawo zogwirira ntchito. Mofananamo,4X SFF 8482mawonekedwe amatha kupereka bandwidth yowonjezereka kuposa SATA ya single-channel.
IV. Zolemba
Zotsatira za kugwiritsa ntchito mosiyanasiyana: Kulumikiza hard drive ya SATA 3 ku mawonekedwe a SATA 2 kudzachepetsa magwiridwe antchito (kutsika kufika pa mulingo wa SATA 2), koma sipadzakhala mavuto ogwirizana.
Laptop kapena makina a mtundu: Malo amkati ndi ochepa. Ndikofunikira kuti muyang'ane mwachindunji zikalata zovomerezeka kapena malangizo ochotsera.
Zingwe za SATA: Zingwe za SATA 3 zimakhala ndi chitetezo chabwino, koma kuzisakaniza nthawi zambiri sikukhudza kuzindikira (kungakhudze kukhazikika m'malo othamanga kwambiri).
Mu malo a bizinesi, kukonza bwinoSAS SFF-8654 4I 38Pmawonekedwe ndi ofunikira kwambiri. Mukamagwiritsa ntchitoSFF 8654 4I kupita ku U.2adaputala, ndikofunikira kuonetsetsa kuti firmware ndi driver zikugwirizana.4X SFF 8482mawonekedwe, kasamalidwe koyenera ka chingwe ndikofunikira kwambiri kuti chizindikiro chikhale cholimba.
V. Chidule ndi Malangizo
Konzani bwino kuyang'ana zilembo ndi malangizo - zomwe ndi zolunjika komanso zodalirika kwambiri.
Phatikizani kuzindikira mitundu ndi mapulogalamu - kutsimikizira kosiyanasiyana.
Ngati kuli kofunikira, yesani kuthamanga - tsimikizirani momwe ntchito ikuyendera.
Kusiyanitsa bwino mitundu ya SATA kungakuthandizeni kufananiza bwino zida zamagetsi ndikugwiritsa ntchito bwino magwiridwe antchito a zida zosungira. Mukasintha, tikulimbikitsidwa kulumikiza ma drive a solid-state othamanga kwambiri (monga ma SSD) ku SATA 3 interface, ndipo ma hard drive amakaniki amatha kulumikizidwa ku SATA 2 interface kuti asunge zinthu zolumikizirana zothamanga kwambiri.
Kwa ogwiritsa ntchito akatswiri omwe akufuna magwiridwe antchito apamwamba, kumvetsetsa miyezo yolumikizirana mongaSAS SFF-8654 4I 38Pndi yamtengo wapatali kwambiri.SFF 8654 4I kupita ku U.2yankho limapereka njira zolumikizira zosinthika zosungira NVMe. Pakadali pano, ngakhale4X SFF 8482ndi muyezo wakale, ukadali wofunikira m'makina ambiri omwe alipo. Mosasamala kanthu za mawonekedwe omwe akugwiritsidwa ntchito, kuzindikira ndi kukonza kolondola ndikofunikira kwambiri kuti muwonetsetse kuti magwiridwe antchito abwino kwambiri.
