Umsebenzisi ngamnye utsala ingqalelo kwisantya sokufunda idiski enzima xa uthenga, kuba kuxhomekeke ekusebenzeni kokusebenza kwayo. Izinto ezimbalwa zichaphazela le paraerter, esingathanda ukuba sithethe kweli nqaku. Ukongeza, sicebisa ukuba uqhelene nemilinganiselo yesikhombisi kwaye uxelele malunga nendlela yokulinganisa ngokwakho.
Yintoni exhomekeke kwisantya sokufunda
Ukusebenza kwe-magnetic drive kwenziwa kusetyenziswa iindlela ezikhethekileyo ezisebenza ngaphakathi kwezindlu. Bayashukuma, ke, kwisantya sokujikeleza kwabo ngokuthe ngqo kuxhomekeke kufundo kunye neefayile zokubhala. Ngoku umgangatho wegolide uthathwa njengokujikeleza isiphene se-7,200 ivukeli ngomzuzu.
Imodeli enexabiso elikhulu isetyenziswa kwiseva yokufakelwa kweseva kwaye kufuneka inyangwe engqondweni ukuba ukungasebenzi kobushushu kunye nokusetyenziswa kombane kunye nentshukumo enjalo nako nangakumbi. Xa ufunda intloko ye-HDD kufuneka ifudukele kwicandelo elithile lengoma, ngenxa yoku, ukulibaziseka kwenzeka, okuchaphazela isantya sokufunda. Ilinganiselwe kwi-millisecond kunye nesiphumo esifanelekileyo sokusetyenziswa kwekhaya kukulibaziseka kwe-7-14 i-MS.

Isixa se-cache siyichaphazela iparameter ethathelwa ingqalelo. Inyani yile yokuba xa uqala ukubhena kwidatha, zibekwe kwindawo yokugcina okwethutyana - buffer. Okukhona isixa solu gcino, ulwazi ngakumbi apho lunokulingana, ngokulandelelana, ukufunda kwalo okulandelayo kuya kukhawuleza. Kwiimodeli ezidumileyo zokuqhuba ezifakwe kwiikhompyuter zabasebenzisi abaqhelekileyo, i-buffer ye-8-128 MB ifakwe, eyanele ukusetyenziswa kwemihla ngemihla.

Ixhaswe zii-algorithms zediski enzima ineempembelelo ezibonakalayo kwisantya sesixhobo. Ungayithatha umzekelo okungenani i-NCQ (umyalelo wemveli womqolo) - usete yeHardware yokulandelelana komyalelo. Itekhnoloji ikuvumela ukuba uthathe izicelo ezininzi ukuba zilingane ngaxeshanye kwaye ziyakha kwakhona njengendlela esebenzayo. Ngenxa yoku, ukufunda kuya kwenziwa ngokukhawuleza. Ukuphambuka okungaphezulu yitekhnoloji ye-TCQ, enesithintelo kwinani lemiyalelo ethunyelweyo ngaxeshanye. I-SATA NCQ ngowona mgangatho mtsha kakhulu ekuvumela ukuba usebenze ngexesha kunye nemiyalelo engama-32.
Isantya sokufunda sixhomekeke kumthamo wediski, oxhunyiwe ngokuthe ngqo kunye nendawo yokulandela umkhondo kwidrive. Olona lwazi lukhona, ukuqhubela phambili kuya ukufudukela kwicandelo elifunekayo, kwaye iifayile zinokurekhodwa kumaqela ahlukeneyo, eziya kuchaphazela ukufunda.
Inkqubo nganye yefayile isebenza ekufundeni kwaye irekhode i-algorithm yayo, kwaye oku kukhokelela kwisantya semifanekiso efanayo ye-HDD, kodwa kwi-FS eyahlukileyo, iya kwahluka. Thatha ukuthelekisa i-NTFS kunye ne-Fat32 - ezona ndlela isetyenzisiweyo yefayile kwinkqubo yokusebenza yeWindows. I-NTFs iphantsi kobuqhetseba kweendawo ezithile zenkqubo, ke iintloko zediski yenza iintshukumo ezininzi kunamafutha32 efakiwe.
Ngoku sisebenza ngakumbi kwimowudi yokulawula ibhasi, evumela ukuba utshintshe idatha ngaphandle kweprosesa. I-NTFS System isebenzisa enye i-caching kade, ukurekhoda uninzi lwedatha kwi-buffer kamva i-FAT32, kwaye ngenxa yoko, isantya sokufunda siyakhathazeka. Ngenxa yoku, unokwenza ukuba iinkqubo zefayile zamanqatha zihlala zikhawuleza kakhulu kune-NTFS. Asiyi kuthelekisa zonke i-FS namhlanje, sibonise umzekelo owenziwa ngumahluko kwintsebenzo.

Okokugqibela, ndingathanda ukuphawula iinguqulelo zonxibelelwano ze-SATE zonxibelelwano. I-SATA yeSizukulwana sokuqala ine-bandwidth ye-1.5 GB / C, kunye ne-SATA 2 - 3 GB / C, ethi, Xa usebenzisa isantya sanamhlanje.

Imilinganiselo yesantya sokufunda
Ngoku ekubeni siye sajongana neeparamitha ezichaphazela isantya sokufunda, kufuneka ufumane izikhombisi ezilungileyo. Asiyi kuthatha umzekelo wemodeli ethile, enesantya esahlukileyo sokujikeleza kwe-spindle kunye nezinye iimpawu, kodwa zicacisa kuphela ukuba zeziphi izikhombisi ezimele ukuba zingumsebenzi okhululekileyo kwikhompyuter.Quka, kuya kufuneka uthathele ingqalelo into yokuba umthamo wazo zonke iifayile wahlukile, ke ngoko isantya siya kwahluka. Qwalasela ezona zinto zibalulekileyo. Iifayile, zingaphezulu kwe-500 mbs kufuneka zifundwe ngesantya se-150 mb / c, ke ithathelwa ingqalelo ngaphezulu kwaoko kwamkelekileyo. Iifayile zenkqubo-nkqubo zihlala zingabi ngaphezu kwe-8 kb yendawo kwindawo yediski, ke izinga lokufunda okwamkelekileyo ziya kuba yi-1 MB / s.
Idiski yediski ye-HARD
Ngaphezulu sele ufunde malunga nokuba ixhomekeke kwisantya sokufunda idiski enzima kwaye ixabiso eliqhelekileyo. Okulandelayo, umbuzo uphakama, indlela yokulinganisa esi salathisi esigcinweni. Oku kuya kunceda iindlela ezimbini ezilula- ungasebenzisa isicelo se-claschell ye-Windows okanye ukhuphele isoftware ekhethekileyo. Emva kovavanyo, uya kufumana ngokukhawuleza iziphumo. Incwadana yemigaqo-nkqubo eneenkcukacha kunye neenkcazo ngeli nqaku zifundwa kwisabelo esahlukileyo ngeli thuba ilandelayo.
