Umsebenzisi ngamunye uqaphela ijubane lapho i-disk eyinkimbinkimbi ifundwa khona lapho uthenga, ngoba ukusebenza kwayo kuxhomeke kuyo. Le pharamitha ithinteka yizici eziningana ngasikhathi sinye, esingathanda ukukhuluma ngazo ekuhlaleni kwalesi sihloko. Ngaphezu kwalokho, sikunikeza ukuthi uzijwayeze ngezimiso zalesi sibonakaliso futhi sikutshele ukuthi ungayilinganisela kanjani.
Yini enquma ijubane lokufunda
Ukusebenza kwedivaysi yokugcina magnetic kwenziwa ngosizo lwezindlela ezikhethekile ezisebenza ngaphakathi kweso. Bahamba, ngakho ukufunda nokubhala amafayela ngokuqondile kuxhomeke ekuvinjeni kokujikeleza kwabo. Manje izinga legolide libhekwa njengejubane le-spindle lezinguquko ezingu-7200 ngomzuzu.
Amamodeli anenani elikhulu asetshenziswa ekufakweni kwesiphakeli futhi lapha kuyadingeka ukuthi ucabange ukuthi isizukulwane sokushisa nokusetshenziswa kwamandla ngesikhathi sokunyakaza okunjalo kukhulu. Uma ufunda, ikhanda le-HDD kufanele lihambise engxenyeni ethile yethrekhi, ngenxa yalokhu kubambezeleka, okuphinde kuthinte ijubane lokufunda ulwazi. Ilinganiselwa kuma-millisecond kanti umphumela omuhle wokusetshenziswa ekhaya ukulibazisa kwe-7-14 ms.

Usayizi we-cache uphinde uthinte ipharamitha embuzweni. Iqiniso liwukuthi uma uqala ukufinyelela idatha, zifakwa kwisitoreji esincane sesikhashana. Njengoba ivolumu enkulu yalokhu kugcinwa, ulwazi oluthe xaxa lungakwazi ukuhambisana, ngokulandelana, ukufunda kwalo okulandelayo kuzokwenziwa izikhathi eziningana ngokushesha. Kumanothi athandwayo amashayeli afakwe kuma-computer wabasebenzisi abavamile, kunesiphakamiso esingu-8-128 MB ngosayizi, okwanele ukusetshenziselwa nsuku zonke.
Bheka futhi: Kuyini imemori yesikhashana kwi-disk eyinkimbinkimbi
Ama-algorithms asekelwa yi-disk eyinkimbinkimbi nawo anomthelela omkhulu kwijubane ledivayisi. Thatha isibonelo, ungafaka okungenani i-NCQ (Native Command Queuing) - ukufakwa kwehadiwe, umyalo wemiyalo. Lolu buchwepheshe bukuvumela ukuba uthathe izicelo eziningi ngesikhathi esifanayo bese uyakha kabusha ngendlela ephumelelayo kakhulu. Ngenxa yalokhu, ukufunda kuzokwenziwa izikhathi eziningana ngokushesha. Ubuchwepheshe be-TCQ bubhekwa njengento engaphelele, neminye imikhawulo ngenani lemiyalezo efanayo. I-SATA NCQ iyizinga elikugcina elikuvumela ukuba usebenze namaqembu angu-32 ngesikhathi.
Isivinini sokufunda futhi sincike kumthamo we disk, okuhlobene ngokuqondile nendawo yamathrekhi ku-drive. Ulwazi oluthe xaxa, ukuhamba kancane emkhakheni odingekayo, futhi amafayela cishe angabhalwa kumaqoqo ahlukene, okuzophazamisa nokufunda.
I-system ngayinye yefayela isebenza ku-algorithm yayo yokufunda nokubhala, futhi lokhu kuholela ekusebenzeni kwezinhlobo ezifanayo ze-HDD, kodwa kumasefayili efayela ahlukene, kuzohluka. Thatha ukuqhathanisa i-NTFS ne-FAT32 - amasistimu amafayela asetshenzisiwe kakhulu ohlelweni lwe-Windows. I-NTFS ijwayele ukuhlukaniswa kwezindawo ezithile zesistimu, ngakho-ke izinhloko ze-disk zenza ukunyakaza okungaphezu kokuthi i-FAT32 ifakiwe.
Namuhla, ukushayela kuyaqhubeka ngokusebenza ngemodi ye-Bus Mastering, okukuvumela ukushintshanisa idatha ngaphandle kokubamba iqhaza kweprosesa. Uhlelo lwe-NTFS lusasasebenzisa i-caching sekwephuzile, ukubhala iningi lemininingwane ku-buffer kamuva ku-FAT32, futhi ngenxa yalokhu, ijubane lokufunda lihlupheka. Ngenxa yalokhu, kungenziwa ukuthi izinhlelo zefayela ze-FAT zivame kakhulu kune-NTFS. Ngeke siqhathanise wonke ama-FS atholakalayo namhlanje, sasivele sibonise ngesibonelo ukuthi kukhona umehluko ekusebenzeni.

Ekugcineni, ngingathanda ukukhuluma ngenguqulo ye-interface ye-SATA yoxhumano. Isizukulwane sokuqala se-SATA sinomkhawulokudonsa we-1.5 GB / s, futhi i-SATA 2 inamandla ka-3 GB / s, okuyinto, ngokusebenzisa amaklayenti anamuhla kumabhodi omama asekhulile, ingathinta nokusebenza futhi ibangele ukulinganiselwa okuthile.

Ukufunda ngokusheshisa
Manje, lapho sicabanga imingcele ethinta ijubane lokufunda, kubalulekile ukuthola ukuthi ukusebenza kahle kangakanani. Ngeke sithathe isibonelo njengamamodeli athile, ngezivinini ezahlukene zokujikeleza kwe-spindle nezinye izici, kodwa ucacise ukuthi yiziphi izinkomba okufanele zibe ngomsebenzi okhululekile kukhompyutheni.
Kumele futhi kucatshangelwe ukuthi umthamo wazo zonke amafayela uhlukile, ngakho-ke ijubane lizohluka. Cabanga ngezinketho ezimbili ezithandwa kakhulu. Amafayela amakhulu kunama-500 MB kufanele afundwe ngesivinini esingu-150 MB / s, ngakho-ke kuthathwa njengokungavumelekile. Amafayela wesistimu ngokuvamile awahlali ngaphezulu kuka-8 KB we-disk space, ngakho-ke izinga lokufunda elamukelekayo kuzoba ngu-1 MB / s.
Hlola ijubane lokufunda i-hard disk
Ngaphezulu kwakho usufundile ukuthi isivinini sokufunda i-disk eyinkimbinkimbi sincike nokuthi iyiphi inzuzo evamile. Okulandelayo, umbuzo uvela ukuthi ungazimela kanjani ngokuzimela le nkomba ku-drive ekhona. Lokhu kuzosiza izindlela ezimbili ezilula - ungasebenzisa i-Windows classic application "PowerShell" noma landa isofthiwe ekhethekile. Ngemuva kokuhlolwa, uzothola ngokushesha umphumela. Izincwadi eziningiliziwe kanye nezincazelo ngale ndaba zingatholakala kumininingwane yethu ehlukile kusixhumanisi esilandelayo.
Funda kabanzi: Ukuhlola ijubane le diski eyinkimbinkimbi
Manje uyazi ulwazi mayelana nesivinini sokufunda amashayela angaphakathi kanzima. Kumele uqaphele ukuthi uma uxhumeke nge-USB isikhangisi njengedrayivu yangaphandle, ijubane lingase lihluke, ngaphandle uma usebenzisa i-port version 3.1, ngakho gcina lokhu engqondweni uma uthenga i-drive.
