Umsebenzisi ngamunye unaka isivinini sokufunda se-hard drive lapho uthenga, ngoba ukusebenza kahle komsebenzi wawo kuncike kulokhu. Le paramu ithonywa yizici eziningana ngasikhathi sinye, esingathanda ukukhuluma ngaso ngohlaka lwalesi sihloko. Ngaphezu kwalokho, siphakamisa ukuthi uzijwayeze nezinkomba zale nkomba futhi ukhulume ngokuthi ungazikala kanjani wena.
Yini enquma ijubane lokufunda
Umsebenzi we-magnetic drive wenziwa kusetshenziswa izindlela ezikhethekile ezisebenza ngaphakathi kwecala. Ziyathutha, ngakho-ke ukufunda nokubhala amafayela ngokuqondile kuya ngesivinini sokujikeleza kwawo. Manje izinga legolide lijubane le-spindle lika-7200 rpm.
Amamodeli ngokubaluleka okukhulu asetshenziswa ekufakweni kweseva, futhi lapha kufanele kukhunjulwe ukuthi isizukulwane sokushisa nokusetshenziswa kukagesi ngalesi sikhathi sokuhamba nakho kukhulu. Lapho ufunda, inhloko ye-HDD kufanele idlulele esigabeni esithile sethrekhi, ngenxa yalokhu kukhona ukubambezeleka, okuthinta nesivinini semininingwane yokufunda. Kukalwa kuma-milliseconds futhi umphumela ofanele wokusetshenziswa kwasekhaya uthathwa njengokubambezeleka kwe-7-14 ms.

Ubukhulu be-cache buthinta ipharamitha okukhulunywa ngalo. Iqiniso ngukuthi okokuqala lapho bethola imininingwane, babekwa kwisitoreji sesikhashana - isiphazamisi. Lapho likhulu ivolumu lalesi sitoreji, imininingwane eminingi ingalunga lapho, ngokulandelana, ukufundwa kwayo okulandelayo kuzoba kaningana ngokushesha okukhulu. Kumamodeli we-drive adumile afakwe kumakhompyutha wabasebenzisi abajwayelekile, kufakwe i-buffer ye-8-128 MB, enele ukusetshenziswa nsuku zonke.

Ama-algorithms asekelwa yi-hard disk nawo anomthelela omkhulu ekusebenzeni kwensiza. Ungathatha njengesibonelo okungenani i-NCQ (i-Native Command Queiding) - ukufakwa kwe-hardware kokulandelana kwemiyalo. Lobu buchwepheshe bukuvumela ukuthi wamukele izicelo eziningi ngasikhathi sinye futhi uzakhe kabusha ngendlela ephumelelayo. Ngenxa yalokhu, ukufunda kuzoba kaningana ngokushesha okukhulu. Ubuchwepheshe be-TCQ buthathwa njengabaphelelwe ngaphezulu, obunomkhawulo othile ngenani lemiyalo ethunyelwe ngasikhathi sinye. I-SATA NCQ iyindinganiso yakamuva, ekuvumela ukuthi usebenze kanyekanye namaqembu angama-32.
Ijubane lokufunda libuye lincike kwinani lediski, elihlobene ngqo nendawo yamathrekhi ku-drive. Imininingwane ethe xaxa, ukuhamba kancane kuya emkhakheni oludingekayo, futhi amafayela kungenzeka abhalelwe amaqoqo ahlukene, okuzophazamisa ukufunda.
Uhlelo ngalunye lwefayela lusebenza ngokuya ngokufunda nokubhala kwama-algorithm, futhi lokhu kuholela ekutheni ukusebenza kwamamodeli afanayo we-HDD, kepha ezinhlelweni ezihlukile zamafayela, kuzohluka. Ukuze uqhathanise, thatha i-NTFS ne-FAT32, amasistimu wefayela asetshenziswa kakhulu kuhlelo lokusebenza lweWindows. I-NTFS ithambekele kakhulu ekuhlukaniseni izindawo ezithile zohlelo, ngakho-ke amakhanda wediski enza ukunyakaza okuningi kunakufakiwe iFAT32.
Manje amadiski amaningi ngokuqhubekayo asebenza ngemodi ye-Bus Mastering, ekuvumela ukuthi ushintshe idatha ngaphandle kokubamba iqhaza kweprosesa. Uhlelo lwe-NTFS lusebenzisa ukulondolozwa kwesikhashana okubhalwe phansi, lubhala imininingwane eminingi buffer ngemuva kwe-FAT32, futhi ngenxa yalokhu, ijubane lokufunda liyahlupheka. Ngenxa yalokhu, ungenza izinhlelo zefayela le-FAT zivame ukushesha kune-NTFS. Ngeke siqhathanise yonke i-FS ekhona njengamanje, sisanda kukhombisa ngesibonelo ukuthi kunomehluko ekusebenzeni.

Ekugcineni, ngithanda ukuqaphela inguqulo ye-SATA interface interface. I-SATA yesizukulwane sokuqala ine-bandwidth ye-1.5 GB / s, ne-SATA 2 - 3 GB / s, okuthi uma usebenzisa izishayeli zesimanje kumabhodi amadala asekhulile kungathinta ukusebenza futhi kubangele ukulinganiselwa okuthile.

Izinga lokufunda
Manje njengoba sesithole amamaki athinta ijubane lokufunda, sidinga ukuthola izinkomba ezifanele. Ngeke sithathe amamodeli ukhonkolo njengezibonelo, ngesivinini esilinganayo sesindilinga nezinye izici, kodwa mane ucacisa ukuthi yiziphi izinkomba okufanele zibe ngumsebenzi onethezekile kwikhompyutha.
Kufanele futhi kubhekwe ukuthi umthamo wawo wonke amafayela uhlukile, ngakho-ke, ijubane lizohluka. Cabanga ngezindlela ezimbili ezaziwa kakhulu. Amafayela amakhulu kuno-500 MB kufanele afundwe ngejubane le-150 MB / s, khona-ke kubhekwa njengokwamukelekayo. Amafayela esistimu, noma kunjalo, ngokuvamile awathathi ngaphezu kwe-8 KB yesikhala sediski, ngakho-ke isilinganiso esamukelekayo sokufunda sawo singaba yi-1 MB / s.
Hlola isivinini sokufunda idiski kanzima
Ngaphezulu, usufundile mayelana nokuthi ijubane lokufunda lediski elilukhuni lincike kuphi nokuthi liyini inani elijwayelekile. Okulandelayo, kuphakama umbuzo, ukuthi ungasilinganisa kanjani ngokuzimele lesi sikhombisi ku-drive ekhona. Izindlela ezimbili ezilula zizokusiza ngalokhu - ungasebenzisa uhlelo lokusebenza lweWindows lasendulo. I-PowerShell noma landa isoftware ekhethekile. Ngemuva kokuhlolwa, uzothola umphumela ngokushesha. Funda imihlahlandlela eningiliziwe nezincazelo ngalesi sihloko ezintweni zethu ezihlukile kusixhumanisi esilandelayo.
Funda kabanzi: Ihlola ijubane le-hard drive
Manje usuwazi imininingwane ephathelene nesivinini sokufunda sokushayela kanzima kwangaphakathi. Kuyaqapheleka ukuthi uma uxhuma ngesixhumi se-USB njenge-drive yangaphandle, ijubane lingahluka ngaphandle kokuthi usebenzisa inguqulo engu-3.1 port, ngakho-ke gcina lokhu engqondweni lapho uthenga idrayivu.
