Kwixesha ledijithali, ii-hard drives zihlala zisisiseko sezisombululo zokugcinwa kwedatha kusetyenziso lomntu kunye nobungcali. Ukuqonda ubunzima bendlela abasebenza ngayo kunye nokukhetha eyona ilungileyo kunokuphucula kakhulu amava akho ekhompyuter. Esi sikhokelo siya kuhamba kwihlabathi lee-hard drives, sikhanyisele ekusebenzeni kwazo, iingenelo, kunye nendlela yokwenza ukuba zisebenze kakuhle kuwe.

Yintoni i-hard drive
I-hard drive, okanye i-hard disk drive (i-HDD), sisixhobo sogcino lwedatha esisetyenziselwa ukugcina nokubuyisela ulwazi lwedijithali usebenzisa idiski enye okanye ezininzi eziqinileyo ezijikeleza ngokukhawuleza (iipleyiti) eziqatywe ngezinto ezinozibuthe. Ezi zixhobo zizinto ezisisiseko zeekhompyuter, iilaptops, kunye nezinye izixhobo zombane ezifuna ukugcinwa kwedatha. Ii-hard drives ziye zavela kakhulu ngokuhamba kwexesha, ukusuka ekunikezeni i-megabytes encinci yokugcina ngeentsuku zokuqala ukuya kuthi ga ngoku ukuqhayisa ngezakhono zeeterabytes ezininzi.
Ii-hard drives zahlulwe kwi-slid-state drives (SSDs) ngamalungu abo omatshini. Ubukho bezinto ezihambayo-ezifana neediski ezijikelezayo kunye nokufunda / ukubhala iintloko-zibahlula kwii-SSD, ezigcina idatha kwimemori ye-flash kwaye zingenazo iindawo ezihambayo. Lo mahluko usisiseko awuchaphazeli kuphela isantya kunye nokuqina kwesixhobo kodwa nokufaneleka kwaso kwiimfuno ezahlukeneyo zokugcina.
Ngaphandle kokunyuka kokugcinwa kwamafu kunye ne-SSD, ii-hard drives ziqhubeka zibamba umhlaba, zibonelela ngeendleko ezisebenzayo, izisombululo zokugcina umthamo ophezulu. Badlala indima ebalulekileyo kumaziko edatha, iikhompyuter zedesktop, kunye needrive zangaphandle zokugcinwa, zibonelela ngendlela ethembekileyo yokugcina inani elikhulu ledatha kwixesha elide.
Isebenza njani i-hard drive
Embindini wokusebenza kwe-hard drive kukukwazi ukugcina idatha ngemagnethi. Iipleyiti ezingaphakathi kwi-hard drive zigqunywe ngento enozibuthe kwaye zahlulwe zaba ziibhiliyoni zeendawo ezincinci, nganye iyakwazi ukwenziwa nguzibuthe ngokwayo. Ezi ndawo zimele idatha yokubini (0 kunye no-1s) ezenza iifayile kunye neenkqubo kwikhompyuter yakho.
Xa idatha ibhaliwe kwi-hard drive, intloko yokufunda/yokubhala ihamba ngapha komphezulu wesitya ngelixa ijikelezisa. Intloko iguqula indlela yemagnethi kwicandelo ngalinye edlula kuyo, ifaka ikhowudi yedatha njengeepateni zemagneti. Idatha yokufunda isebenza kumgaqo wokufumanisa ezi patheni. Njengoko iipleyiti zijikeleza, iintloko ezifundwayo/zibhala zindanda nje ngeenanometers ngaphezulu komphezulu, zibona umhlaba wemagnethi ngaphandle kokudibana ngokwasemzimbeni.
Lo mdaniso untsonkothileyo wokusonta iipleyiti kunye neentloko ezihambayo zilungelelaniswe yi-hard drive's firmware, isoftware ekhethekileyo elawula ukusebenza kwehardware. Ilawula indawo ebonakalayo yedatha, igcina umkhondo wamacandelo amabi, kwaye iqinisekisa ukunyaniseka kwedatha ngexesha lokufunda / ukubhala imisebenzi. Le ndlela entsonkothileyo ivumela ii-hard drives ukuba zigcine kwaye zifikelele kwixabiso elikhulu ledatha ngokuthembekileyo, nangona ngesantya esicothayo kunoogxa babo be-SSD.
Izibonelelo kunye neengxaki zee-hard drives
Iidrayivu ezinzima zinika umxube onyanzelisayo weenzuzo ezenza zibe ukhetho olunomtsalane kwizicelo ezininzi zokugcina. Enye yeenzuzo zabo ezibalulekileyo kukusebenza kakuhle kweendleko. Ngokwe-gigabyte nganye, ii-hard drives zifikeleleka ngakumbi kune-SSD, zibenza babe lolona khetho lubalaseleyo kwiimfuno zogcino oluphezulu ngaphandle kokwaphula ibhanki. Baziwa nangokuphila ixesha elide xa kufikwa kugcino lwedatha, ekwaziyo ukugcina idatha iminyaka okanye amashumi eminyaka ngaphandle kwamandla.
Nangona kunjalo, ii-hard drives azikho ngaphandle kokuphazamiseka kwazo. Ubume babo boomatshini bubenza babe sesichengeni ngakumbi kumonakalo womzimba ukusuka kumothuko okanye ukuhla, okunokukhokelela ekulahlekeni kwedatha. Zikwacotha xa kuthelekiswa nee-SSD, ngakumbi kwimisebenzi efuna ufikelelo olukhawulezayo kwidatha, efana nokuqalisa inkqubo yokusebenza okanye ukuqaliswa kwezicelo. Ngaphaya koko, ii-hard drives zisebenzisa amandla amaninzi ngenxa yeendawo zazo ezihambayo, ezinokuthi ziqwalaselwe izixhobo ezisebenza ngebhetri.
Indlela yokukhetha i-hard drive
Ukukhetha i-hard drive echanekileyo ibandakanya ukuthathela ingqalelo izinto ezininzi ezibalulekileyo ezilungiselelwe iimfuno zakho ezithile. Umthamo udla ngokuba yeyona nto iphambili; cinga malunga nokuba ingakanani idatha ofuna ukuyigcina ngoku nakwixesha elizayo. Isantya, esilinganiswe kwiinguqu ngomzuzu (RPM), sichaphazela ukuba idatha ingafundwa ngokukhawuleza okanye ibhalwe kwi-drive-i-RPM ephezulu ithetha ukusebenza ngokukhawuleza.
Olunye uqwalaselo olubalulekileyo lujongano, kunye ne-SATA yeyona nto ixhaphakileyo kwiidrive zangaphakathi, ngelixa iidrive zangaphandle zinokusebenzisa i-USB, iThunderbolt, okanye unxibelelwano lweSATA. Ifom factor ikwabalulekile, kunye ne-3.5-intshi yedrive esemgangathweni yeedesktops kunye ne-2.5-intshi yeelaptops. Ekugqibeleni, ukuthembeka kunye newaranti yimiba ebalulekileyo, ebonisa ukuzithemba komenzi kwimveliso yabo.
Indlela yokusebenzisa i-hard drive
Ukusebenzisa i-hard drive ngokufanelekileyo kubandakanya ukufakela okufanelekileyo, ukugcinwa, kunye nolawulo. Ukulungiselela iidrive zangaphakathi, qinisekisa ukuhambelana ne-motherboard yekhompyuter yakho kunye neendawo ezikhoyo zokuqhuba. Ukufakela ngokuqhelekileyo kufuna ukudibanisa i-drive kwi-motherboard kunye nokunikezelwa kwamandla usebenzisa iintambo ezifanelekileyo. Kwiidrive zangaphandle, ihlala ilula njengokudibanisa idrayivu kwikhompyuter yakho nge-USB okanye olunye ujongano.
Ukugcina i-hard drive yakho ibandakanya i-backups rhoqo, i-defragmentation (ye-HDDs), kunye nokubeka iliso kwiimpawu zokusilela, njengengxolo engaqhelekanga okanye ukusebenza kancinci. Ukulawula ngokufanelekileyo idatha kwi-hard drive yakho kunokuphucula ukusebenza kwayo kunye nokuphila ixesha elide, njengokucwangcisa iifayile ngokufanelekileyo kunye nokuphepha ukuzalisa i-drive kumthamo wayo, onokucothisa isantya sokufunda/sokubhala.
isiphelo
Ii-hard drives zihlala ziyinxalenye ebalulekileyo yezicwangciso zokugcinwa kwedijithali, ezinikezela ngebhalansi yomthamo, iindleko, kunye nokuthembeka. Ukuqonda indlela abasebenza ngayo, izibonelelo zabo kunye nemida, kunye nendlela yokukhetha nokuyisebenzisa kunokuchaphazela kakhulu izenzo zakho zokulawula idatha. Nokuba kukusetyenziswa komntu, usetyenziso lweshishini, okanye amaziko edatha, ii-hard drives ziyaqhubeka nokubonelela ngesiseko esithembekileyo sokugcina umthamo okhulayo wolwazi lwedijithali kwihlabathi lethu.
