Izinto eziphambili zokuThatha

IiHDD zibalulekile kugcino lwedatha enkulu kwikhompyuter yanamhlanje.

Uyilo lwezakhiwo lubandakanya amacandelo afana neepleyiti zealuminiyam kunye nemoto yokuphotha.

Ugcino lwedatha luxhomekeke ekuguquleni imagnethi polarity yomphezulu wepleyiti.

Ukurekhoda ngemagnethi yinkqubo apho idatha ibhalwa kwaye ifunyenwe.

Indibaniselwano yobunjineli kunye nezinto ezizibuthe zenza iiHDD zomelele kwaye zisebenze kakuhle.

Ii-SSD zigcina njani iDatha?

Ii-SSD ziyahluka kwiidrive zediski zemveli (HDDs) kuba ziswele iindawo ezihambayo. Basebenzisa i-NAND flash memory chips ukugcina idatha. Le teknoloji ikhusela idatha nangona kungekho mbane.

Ii-SSD zigcina idatha ngenkqubo yegridi yombane. Inkqubo yohlulwe ibe ngamaqhekeza. Yenza ugcino lwedatha kunye nolwakhiwo lusebenze ngakumbi.

Ukubhala idatha kwi-SSD kubandakanya iindlela ezininzi. Ezi ndlela zinceda ukubethela idatha ngokuchanekileyo. Enye into ebalulekileyo omele uyazi kukubhala ukukhulisa.

Ukwandiswa kokubhala kwenzeka xa idatha eninzi ibhaliwe kunokuba bekucetywayo. Kubalulekile ukuqonda ukuba ii-SSD zihlala njani kwaye zisebenze kakuhle.

Njani HDD Gcina Data?

Ii-Hard Disk Drives (HDDs) zigcina idatha ngokuyibhala kwiipleyiti zedisk. Ezi zicwecwe zenziwe ngeglasi okanye ialuminiyam kwaye zinemagnethi yokwaleka. Zicwangciswe ngokwezangqa ezibizwa ngokuba ziingoma, ezahlulahlulwe zibe ziindawo ezincinci ezibizwa ngokuba ngamacandelo.

Idatha igcinwa yintloko efundwayo kwi-activator arm. Le ntloko idada ngaphezulu kwepleyiti, itshintsha imimandla yemagnethi. Olu tshintsho lubangelwa yi-magnetic flux, enceda ukugcina idatha ngokuchanekileyo.

Ngaphambi kokusetyenziswa, i-HDD ihamba ngokufomatha okukumgangatho ophantsi. Eli nyathelo limisela iingoma kunye namacandelo kwiipleyiti. Emva koko, ukufomatha okukwinqanaba eliphezulu kudala ulwakhiwo lwesixokelelwano sefayile. Oku kuvumela inkqubo yokusebenza yekhompyuter ilawule kwaye ifikelele kwidatha ngokufanelekileyo.

FAQ

Yintoni indima yemoto yokuphotha kwii-HDD?

Ngawaphi amacandelo aphambili abandakanyekayo ekugcinweni kwedatha ngaphakathi kweHDD?
Ukugcinwa kwedatha ye-HDD kubandakanya amacandelo amaninzi: iipleyiti zedisk, iintloko zokufunda, i-activator arm, i-spindle motor, kunye ne-magnetic material coating. Iipleyiti zeDiski zihlulwe zibe yimizila kunye namacandelo, apho idatha igcinwa ngokuguqula imimandla yamagnetic. Kwizisombululo ezikhethekileyo zokugcina idatha, ukuhlola iinketho ukusuka abavelisi beekhompyutha zoshishino inokuba luncedo.

Ngaba ukufomatha okukwinqanaba eliphezulu kwahluke njani kulungiselelo lomgangatho ophantsi?
Ukufomatha okukwinqanaba eliphezulu kuseka inkqubo yefayile kwi-HDD, evumela inkqubo yokusebenza ukuba ilawule, ifumane, kwaye isebenzise idatha egciniweyo ngokufanelekileyo. Ilandela ukufomatha okukwinqanaba elisezantsi kwaye iyimfuneko ekudityanisweni kweHDD nenkqubo yekhompyuter. Ukulungiselela uhlengahlengiso, a ithebhulethi eqinileyo eneWindows 11 ingaba sisisombululo esiphathwayo.

Kutheni i-magnetic flux ibalulekile kwi-HDD yokugcina idatha?
Imagnethi iguquguquka ilinganisa amandla omhlaba wemagnethi aveliswa yintloko yokufunda-bhala, eguqula imimandla yemagnethi kwipleyiti ukugcina idatha. Ukuchaneka kwi-magnetic flux ibalulekile ekuchanekeni kwedatha kunye nokuthembeka kwii-HDD.

Yiyiphi indima edlalwa yi-magnetic domains kwii-HDDs?
Imimandla yemagnethi yimimandla emincinci ngaphakathi kwesixhobo semagnethi kwipleyiti yedisk. Indawo nganye imagnethi polarity ingatshintshwa imele amasuntswana edatha. Ulungiselelo kunye noqhelaniso lwale mimandla lumisela ulwazi olugciniweyo lokubini. Kwiimfuno zekhompyuter ezihlala zihleli, a iPC encinci okanye i ishishini PC Advantech inokunika ukusebenza okuthembekileyo kokugcinwa kwedatha kunye nohlalutyo.
