Indawo yediskhi esekhompyutheni - ukuba ... njani ukuze ukhethe nzima ukuya ikhompyutha kunye laptop drive

hard - kuqukwa amacandelo athile eso PC okanye kwi laptop yakho. yokusebenza ikhompyutha ixhomeke iimpawu ezi zixhobo. Ziziphi iintlobo nzima drives thaca kwi kwimarike namhlanje? Indlela ukukhetha ilungileyo ukusuka kwindawo Ngenxa yokusombulula isixhobo eqhelekileyo imisebenzi umsebenzisi?

Yintoni hard drive?

Hard drive - yeyona isixhobo esingundoqo yokugcina ifayile kwi PC yakho okanye kwi laptop yakho. Constructional i ipleyiti rotary kunye ukufunda Imagnethi yomhlaba kunye nokurekhodisha ilungu - entloko. Slang kubalandeli zobugcisa computer ubizwa ngokuba 'hard drive "," lizulu "," kunzima ". Ezi nkcukacha ye esebenzayo hard drive olesayo nangaxeshanye intloko ukurekhodwa ayikho ukudibana kunye nembasa ngemagnethi. Ngenxa oku, kwakunye nenani nezinye iimpawu zoyilo, ifowuni isebenza ithuba elide kwaye sijongwa njengenye indlela inokuthenjwa ukwenzela ukugcina ulwazi.

Hard drive - kweziBonelelo, nto leyo, njengokuba umthetho, indawo iifayile nkqubo, oko kukuthi, abo anokufumaneka isakhiwo OS, izicelo ezininzi, imidlalo. Faka i software phantse lonke busenza ukuba ukubandakanyeka kwezibonelelo "hard drive."

Uninzi computer mihla lixhasa ezininzi hard disk. Ephathekayo ngokufuthi wabeka nzima enye kuphela drive - ngenxa imilinganiso encinane izixhobo ezifanelekileyo. Kulo mzekelo, xa kuziwa kumacebo okugcina angaphandle ezifana (ingakumbi kwabo siza kuqwalasela kamva), inani eliphezulu zabo ngokufuthi umda nokufumaneka slot ezifanelekileyo kwi-PC, kwakunye iimpawu yokusebenza ye khompyutha.

Ngenxa yoko, i-hard drive - icandelo yentsimbi lubalulekileyo computer. Umsebenzi wethu - ukumisela Iikhrayitheriya zokukhetha ngokupheleleyo PC efanelekileyo devaysa. Ukuze nilicombulule, kuya kuba luncedo ukuba uqale ukuhlola uhlelo "hard drive."

Ukwahlukanisa nzima drives

Cinga, ke ngoko, kuyo nayiphi na uhlobo lizisa disks mihla nzima kwi kwimarike nobuchwepheshe computer.

Phakathi iintlobo uthandwayo izixhobo - ikhompyutha hard drive, okuhambelana uhlobo eyongeziweyo 3.5 intshi. compact anjalo isantya ojikeleza ngaso yeenguqu 5400 okanye 7200 ngomzuzu. Unxibelelwano "drives" ne PC nge lwenjongano ezahlukeneyo. Eyona ziqhelekileyo - IDE kunye wada wabiliswa uphela.

Kukho drives nzima eyenzelwe kubancedisi. ubukhulu sabo ngokubanzi ngokufanayo kwi PC, kodwa isantya ojikeleza ngaso yezixhobo ezinjalo iphezulu kakhulu - ngokulandelelana yeenguqu 15,000 ngomzuzu. "Drives Nzima" kubancedisi eqhagamshelwe kumacandelo iintsimbi eziphambili rhoqo nge ujongano SCSI, kodwa unako inkxaso wada wabiliswa uphela okanye SAS imigangatho serial. Umncedisi Hard Drive - isixhobo oluthembekileyo kakhulu, nto leyo ayimangalisi: iikhompyutha apho ezi drives zibekwa, ekujongwe ukuba bakhonze kwiinkalo ezingundoqo kwiinkampani zeziseko digital, imibutho karhulumente, ababoneleli ngenkonzo Internet.

Ezi ntlobo "drives" zixhomekeke kufako kwi PC semoto okanye umncedisi. Kodwa ke zikhona lwangaphandle nzima drives. Bona kubekanye kwizithuba ze kumazibuko lwangaphandle ikhompyutha - inkoliso yabo yonke USB okanye Ucingo lomlilo. ukusebenza yabo iyafana jikelele ukuba lowo ubonakalise uhlobo isixhobo lwangaphakathi. isithuba hard disk ukubayinxalenye kudidi zangaphandle, njengoko umthetho, enkulu kangangoko - malunga 500-1000 GB. Isibakala sokuba olu hlobo isixhobo idla lingasetyenziswa ukusa ukusuka kwenye ikhompyutha ukuya kwenye izixa ezikhulu data.

Kukho drives nzima, aguqulelwe laptops. isayizi yazo incinane "HDD", zenzelwe kuzo i "desktop" ikhompyutha - 2.5 intshi. indawo yediskhi Isantya nzima ukuba laptop - ngokuqhelekileyo 4200 okanye 5400 rpm. Yokuyisebenzisa drives enjalo ngokuqhelekileyo xa ngokumandla wada wabiliswa interface. Lubonakala ngokuba ukuxhathisa ophezulu utshintsho indawo, apho kusengqiqweni ngenxa nkcukacha zokusebenzisa zokubhalela.

Phakathi iintlobo ezininzi enobuchwepheshe of drives nzima - SSDs. Bathi ke, umgaqo, zingathathwa njengodidi olwahlukileyo izixhobo, ekubeni isakhiwo wabo akukho amacwecwe ehambayo. Idatha kolu hlobo lwe disk nzima drives abhalwe ukuba idanyaze memory. Devices yale hlobo bobabini ezilungileyo nezingalunganga.

Uninzi ekhokela abenzi PC liya ngokuhlenga imigca zabo mveliso ekuveliseni izixhobo, lixhotyiswe okuqinileyo karhulumente drives. Olu hlobo nzima drives zibiza kakhulu kunalawo isakhiwo apho izinto ejikelezayo akhoyo. Nangona kunjalo, xa kuthelekiswa nawo, baya luphawulwa ukusetyenziswa eliphantsi ngamandla, phantse ukungabikho iyonke ingxolo emsebenzini, kwiimeko ezininzi - ubunzima ngaphantsi. Relative ukuba isantya yokosulela data ukuba kuqatshelwe izinga okufana okuqinileyo-state drives hard - 300-400 MB / umzuzwana, leyo enesidima kakhulu kwi imvelaphi eziphambili nemigangatho zonxibelelwano exhaswa yi computer mihla.

interface

ufakelo ngempumelelo le disk nzima kwi PC ixhomekeke kakhulu ubukho interfaces ezifunekayo. Cinga nkcukacha zemigangatho zonxibelelwano iqhelekileyo kwi emalikeni izixhobo zekhompyutha. Oku kuza kuba luncedo correlating imisebenzi umsebenzisi kunye nohlobo "indawo yediskhi esekhompyutheni", leyo ezifaneleke ngeyona ukuhlangabezana nazo.

Phakathi kujongano zixhaphakileyo loqhakamshelwano drives lwangaphandle nzima - USB. Ngaloo umgangatho wonxibelelwano olusebenzayo zinganikezelwa kwiinguqulelo ezahlukeneyo - 1, 2, no-3 isantya hard disk ixhomekeke ngqo kwi ukuhambelana kwayo ngeteknoloji efanelekileyo. Ngokuphathelele inguqulelo woku-1 esibonakalayo, ungenza zithi xa kusetyenziswa ngayo ukuze adlulisele data kwi Mbits 12 / umzuzwana, luqinisekisa 2nd ifayile ukwabelana ngesantya ukuya ku-480 Mbit / s, 3 kwesizukulwana USB-ujongano inika isalathiso ukuya 5 Gbit / s. Ukuba ufuna ukusebenzisa ifowuni ayikho kuphela iifayile ivenkile, kodwa, umzekelo, ukufaka imidlalo okanye iinkqubo, kungcono ukuba kukugcina ujongano USB yangoku - ezininzi kwinguqulelo-2, yaye ngcono nangowesithathu.

ikhompyutha yangaphandle hard drive kananjalo enxulumene ujongano Ucingo lomlilo. Lubonakala yi izinga data eliphezulu - malunga 400 Mbit / umzuzwana. Yeyokuba isebenza kakhulu xa besebenza kunye neefayile zevidiyo.

Cinga imigangatho esetyenziswayo xa ufaka drives lwangaphakathi uhlobo PC. Njengento ujongano kodwa noko ugugile, ethandwayo - IDE.

It angadlulisela data ngesantya malunga 133 MB / umzuzwana. Eziqhelekileyo bekhompyutha - ubukhulu becala ngenxa isixa kunokuba elikhulu izihlanganisi kwi non-eliphezulu isakhiwo laptop noshowo.

Wada wabiliswa uphela yekhompyutha - isiphumo yokuphucula umgangatho IDE. It ikuvumela ukuba ukudlulisela data ngesantya ukuya ku-300 MB / umzuzwana. It ebonakala okukwazi eliphezulu kuphazamiseko. Luphawu ezisetyenziswa kweekhompyutha eziphathwayo - kubulelwe ubungakanani elincinane ngokwentelekiso isinxibelelanisi, kwakunye nezinga data elungileyo.

SCSI interface, njengoko sibonile ngentla apha, ibekwe ikakhulu phezu abancedisi. Linophawu izinga data eliphezulu - malunga 320 MB / umzuzwana. Kukho ukulungisa zaphuculwa zojongano kwengxelo - SAS. HDDs ukuba asebenza phantsi ngokunxibelelana zinganika lonaniselwano data kwi umyalelo izinga 12 Gb / s.

Iikhrayitheriya zokukhetha disk hard

Iinkcukacha Interface siye saxubusha ingentla ingqalelo njengendlela ebalulekileyo xa ukhetha i hard drive. Kwakhona siphakamise ukuba inani nezinye iparameters ezibalulekileyo - ezifana ngesantya njengokujikeleza izinto devaysa ifomu factor. Kodwa mhlawumbi, kukho inkalo ebalulekileyo kukhethwa imodeli eliphezulu devaysa uphawu - hard memory disk. Ngeendlela ezininzi, olu khetho luluvo - abasebenzisi abaninzi bakhetha ngokukhawuleza "hard drive" kunalowo apho kuya kuba lula ukubeka inani elikhulu leefayile. Nangona kunjalo, le disk amandla nzima - kusekho into yokuqala uhlawula ingqalelo kubasebenzisi abaninzi.

Eyona nkalo ibalulekileyo ukukhetha "Winchester" - ezinye iimpawu zayo wesiqhelo (umz, ngokuhambiselana nale okanye ezinye ujongano) kufuneka esihambisanayo nale unxibelelwano izakhono ze-PC. Kwenzeka ke ukuba ikhompyutha hard disk aku- yobuchwepheshe, kodwa nenkxaso kwimigangatho efanelekileyo kwi PC motherboard ayonelanga. Cinga bokuqonda isitshixo wokuhambelana "drives 'yaye amanye amacandelo iintsimbi i kweekhompyutha mihla.

Ubukhulu Ezibalulekileyo wokuhambelana

Ngaphezu sibonile ukuba drives hard ziyahluka ubukhulu. Kusenokwenzeka kubonakale ukuba lo parameter - minor. Kodwa ke ujika ube phantse izigqibo. Isibakala sokuba ukufakela disk nzima PC yakho okanye kwi laptop yakho ukuya kwindawo efanelekileyo kuya kuba nzima kakhulu, ukuba ubukhulu yokugcina lincinane kakhulu, kwaye ke ngoko sub-ngokupheleleyo ngokubhekiselele ekusetyenzisweni kwe-indawo efumaneka kulwakhiwo devaysa. Bekuya kuba nzima ukuba imilinganiselo zinkulu kakhulu - "hard drive" nto nje abanakwanela na ikhompyutha.

Kakade ke, le ndlela ekuso ikakhulu ngenxa laptops, njengoko iingxaki kunye nokubekwa lwe disk nzima kwi PC "desktop" ngokuqhelekileyo ongaphunyelwayo ntoni (ubukhulu becala ngenxa ukufumaneka lwezincedisi ezahlukeneyo ozikhethelayo). Ngoko ke, xa uceba ukuthenga hard drive elitsha laptop yakho, kufuneka ukwazi oko ubungakanani ngqo le yangoku. Ngaphezu sibonile ukuba "drives hard 'eqhelekileyo kunye luhlobo ngumba of intshi 2.5 iintlobo ezahlukeneyo ze computer. Kodwa simele sikhumbule ukuba drives hard 1.8 intshi wazibeka ezinye iimodeli laptop.

amazinga zonxibelelwano Ihambelana

Ukuhambelana kufuneka kwakhona ibe unxibelelwano "hard drive" interfaces and motherboard PC. The main caveat apha - umahluko phakathi kweenguqulelo ze zemigangatho exchange data. Ngoko ke, kukho iinguqulelo ezintathu wada wabiliswa interface. Kubalulekile ukuba umgangatho unxibelelwano efanelekileyo ixhaswa ivenkile, nayo ehambelana kunye motherboard. Mhlawumbi kungenzeka ukuba umsebenzisi uthenga into ebizayo, iqinisekisa ukutshintshiselana data kwi yangoku standard wada wabiliswa uphela 3 hard drive (ixabiso imifuziselo ezinjalo kunokuba 10 lamawaka. Hlikihla.), Kodwa ikhompyutha akayi kuba nako ngokupheleleyo inkxaso. umnini PC, ngaloo ndlela, uyakwazi overpay kakhulu.

Kukwanjalo uya kuba kungqinelwano exhaswa nemigangatho "hard disk" kunye USB kwiPC. Ukuba hard drive yenzelwe ukudibanisa nge njengesixokelelwano USB 3.0, kodwa motherboard esi sicwangciso, izakhono zobugcisa asemgangathweni efanelekileyo kwaye ngeke uze ngokupheleleyo. Ngokuphathelele interface Ucingo lomlilo, unako ukuba inkxaso ukuthenga yalo hard disk (isixhobo ixabiso unokuba endilisekileyo - .. 8-10 amawaka engange), kufuneka uqinisekise ukuba PC yakho umgaqo ehambelana nayo. Lo mgangatho unxibelelwano okufana laptops, kodwa angekhoyo abaninzi PC "desktop." Kakade ke, drives nzima, inkxaso Ucingo lomlilo, njengoko umthetho, lo gama kwakhona ehambelana kunye lwenjongano USB, yaye oko akuthandeki kakhulu ukuba icebo liya kuba non-functional ngenxa yokungabikho izibuko Ucingo lomlilo kwi-PC. Kodwa ukuba umsebenzisi, umzekelo, kulindeleke ukuba abandakanye ezi ecaca loncedo lokhuphiswano Ucingo lomlilo - ukusebenza ngokufanelekileyo data ividiyo, awukwazi ukufumana iziphumo ezinqwenelekayo-hard drive.

Imali kahle

Njengokuba sibonile ngentla apha, umthamo njengoko iimpawu eziphambili esi sixhobo, ngathi hard drive - eli parameter ayinyani kakhulu. Abasebenzisi abaninzi kwanele, masithi, a gigabytes embalwa isithuba sediski - umzekelo, ukuba zisebenza ikakhulu kunye namaxwebhu. Umntu kunye drive ulinganiso lweenkcukacha ezinkulu nzima kubonakala ebanzi ngokwaneleyo ukuba ukunyanzela ukuthunyelwa rhoqo imithamo emikhulu isiqulatho multimedia - iividiyo, iifoto, umculo.

Lucebisa ukuba imali ngokupheleleyo zokugcina kunzima. Kodwa ingqiqo ka "kokukhona - ngcono" - akusoloko ukhetho ilungileyo, kwakhona ukusuka kwindawo kwezoqoqosho ngayo. Uyakwazi tirhisa endleleni, esikhulu hard drive - 1TB. yonke ulinganiso lweenkcukacha ezinkulu ifumaneka njalo - kodwa Kuqeqesho zingasetyenziswa phantse isiqingatha. Kulo mzekelo xa uthenga capacious kangako, kodwa umi imali wakhululwa zitshiphu i drive ingasetyenziswa ukuphucula ukusebenza PC yakho okanye kwi laptop yakho (umzekelo, athenge ezongezelelweyo imodyuli RAM okanye kwesibandisi enamandla ngakumbi phezu iprosesa).

Ngokutsho kwinani IT-iingcali, i hard drive 500 GB - isisombululo elilelona ukuba uninzi lwemisebenzi umsebenzisi. Ngoko, kwi "hard drive" umqulu ohambelana inokubekwa malunga 100-150 amawaka. Umfanekiso e quality elungileyo, ukufaka 100-150 imidlalo mihla. Ukuba umnini-PC - hayi fotoshedevrov nomqokeleli hayi ungumdlali, akuthandeki ukuba iqeshe ubuncinane isiqingatha lwecebo ahambelanayo. Kodwa ke amathuba eya kubetha zithi idiski nzima 500 GB, kuba kungenako nokuba nako zaneleyo ukuba yena, naye, unomdla nokufota nemidlalo. Nangona kunjalo, imali "indawo yediskhi esekhompyutheni" sithathwa njengomnye makamisele ngeyona nto intle ngokwemiqathango imisebenzi eqhelekileyo ukuba basombulula kubasebenzisi abaphambili.

ukujikeleza

Enye parameter ebalulekileyo oluphawula hard drive - lelona zinga ukujika amacwecwe. Malunga kunokuthiwa ukuba kubalulekile ukusuka kwindawo Ngenxa izinga transfer idata ngqo kwakunye yokusebenza baphatha Dynamics iifayile ezahlukeneyo. Ukuba 'hard drive "lisetyenziswa ephambili, oko kukuthi, kubalulekile ebaleka, it efakwe iinkqubo nemidlalo, kungcono xa siqwalasela iimpawu ziya luboniswe kukuninzi kangangoko kunokwenzeka. Ukuba umsebenzisi uthenga yesibini hard drive, eyenzelwe ikakhulu ukugcina iifayili, kule mqondo isantya ojikeleza ngaso le amacwecwe - hayi eyona nto ibalulekileyo.

Ukuba liphakamile ixabiso lale salathisi, ugcino ebiza kakhulu. Ngale ndlela, le egqithisileyo ngenxa isantya ephakamileyo nangona yokuba ubukho babo asifuneki, ukuze, kwakhona, akusayi kufuneka. "Winchester" enesantya ujikeleziso disk nekhupha ingxolo ngokubonakalayo ngaphezu kwesinye uguqulela endilisekileyo, kwaye uphawu ebonakala ngalo ukusetyenziswa eliphezulu ngamandla. Izinga eliphezulu nzima disks mihla, apho isigqibo kunokwenzeka ngempumelelo uninzi imisebenzi umsebenzisi - 7200 rpm.

imemori yecache

Phakathi izikhombisi ebonakalayo yokusebenza drive - cache. Ngeebhayisikile le resource, a hard drive kungaba kakhulu ukukhawulezisa iinkqubo zokwenza imisebenzi ezininzi iifayile. I-cache fixed ubuchule zombuzo osetyenziswe kwizixhobo ezithile kwikhompyutha yakho. Ukuba abanye idatha kwi-cache, i "Winchester" akukho mfuneko ukujonga kuzo kwisithuba RAM okanye phakathi iifayile. Ubukhulu efihlakeleyo, ngcono. Kodwa iingcali ezininzi kucetyiswa ixabiso elilelona ehambelana nendawo isalathisi - 64 MB.

Ingaba brand ebalulekileyo?

Ngaba kusengqiqweni ukuba ukhethe hard drive, zonke ezinye izinto ilingana, ugxininise brand? Imibono IT-ziingcali kunye nabasebenzisi ngalo mba yahluke gqitha namhlanje. Oku kusebenza zombini kwiingcebiso kujolisa lophawu, yaye izimvo kumgangatho drives eyenziweyo-mveliso ethile. Abanye abasebenzisi ziimpawu yayo kakhulu omhle, eyakhutshwa yi-Samsung, ncomo drive nzima kwezinye abanini devaysa brand Korean kunokuba ngaphantsi ngehlombe. Ezinye IT-ziingcali bedumisa brand Hitachi, Toshiba, abanye musa ukucinga ukuba babe yinto engcono ngakumbi kukhuphiswano. Nangona kunjalo, ezi nkampani - iinkokeli emarikeni. Le nyaniso, nakweyiphi imeko, kufuneka luthathwe ebalulekileyo.
