Hard disk drive - kungcono ... kanjani ukukhetha hard drive kwikhompyutha kanye ne-laptop

hard drive - kuhlanganise izingxenye ezisemqoka PC noma laptop. ukusebenza Ikhompyutha ixhomeke izici zalezi amadivaysi. Yiziphi izinhlobo hard drive yethulwa emakethe namuhla? Indlela ukukhetha enembako umbono yokuxazulula ejwayelekile imisebenzi umsebenzisi kudivayisi?

Uyini drive kanzima?

idrayivu Hard - main isitoreji ifayela kudivayisi ku-PC yakho noma ikhompyutha ephathekayo. Constructional kuyinto ipuleti rotary efunda kazibuthe kanye ukuqopha ilungu - ikhanda. Slang kubalandeli computer ubizwa ngokuthi "drive kanzima", "umshudo", "kunzima". Imininingwane yalolu isebenze hard drive othi futhi kanyekanye ukuqoshwa ikhanda alikho ukuxhumana ipuleti kazibuthe. Ngenxa yalokhu, kanye eziningi nezinye izici design, idivayisi esebenza isikhathi eside futhi kungenziwa kubhekwe njengento yezindlela onokwethenjelwa kakhulu ukulondoloza ulwazi.

idrayivu Hard - insiza, okuyinto, njengoba umthetho, amafayela uhlelo zitholakala, okungukuthi, labo abakhona kule nokwakheka OS, izicelo ahlukahlukene, imidlalo. Faka isofthiwe kusikisela ukuzibandakanya kwezinsiza cishe njalo "drive kanzima."

Eziningi zanamuhla onobuhle ikhompyutha isekela hard disk oshayelayo. Aphathekayo ngokuvamile ibekwe drive kanzima eyodwa kuphela - ngenxa Ubukhulu encane amadivayisi abafanele. Kulokhu, uma kuziwa amadivayisi isitoreji sangaphandle ezifana (ngokucacile zabo sizocabangela kamuva), inani eliphezulu yabo ngokuvamile engavimba ukutholakala slot ezifanele kwi PC, kanye nezici ukusebenza computer.

Ngakho, i-hard drive - ebaluleke kakhulu hardware ingxenye ikhompyutha. Umsebenzi wethu - ukucacisa ngenqubo Ukukhetha kahle PC devaysa ezifanele. Ukuyixazulula, kuyoba usizo ukuba aqale ukuhlola Ukwahlukaniswa "drive kanzima."

Ukwahlukanisa hard drive

Cabanga-ke, kunoma yisiphi zinhlobo presents yesimanje angaphandle kanzima emakethe ubuchwepheshe bama-computer.

Phakathi ezichumayo amadivayisi - a drive yekhompyutha kanzima, okuhambelana yefomu Isici 3.5 amayintshi. akwazi ukugcina okunjalo abe ijubane ukujikeleza ka 5400 noma 7200 linemibhikisho ngomzuzu. Ukuxhumana "ngemoto" nge PC nge interface ahlukahlukene. Okuvame kakhulu - IDE futhi Sata.

Kukhona nama-hard drive ofanelana amaseva. usayizi yabo ngokuvamile kuyafana PC, kodwa ijubane ukujikeleza amadivayisi enjalo iphezulu kakhulu - ngokulandelana 15,000 linemibhikisho ngomzuzu. "Ngemoto Hard" ngoba amaseva exhunywe kwi-main izingxenye hardware ngokuvamile nge esibonakalayo SCSI, kodwa angakwazi ukusekela serial Sata noma SAS amazinga. Iseva Hard Drive - kudivayisi okunokwethenjelwa kakhulu, okuyinto akumangalisi: amakhompyutha lapho lezi ngemoto ifakwa, eyenzelwe ukusiza izindawo ezibalulekile izinkampani ingqalasizinda digital, izinhlangano zikahulumeni, service Internet.

Lezi zinhlobo "ngemoto" angaphansi ukufakwa PC chassis noma iseva. Kodwa kukhona wangaphandle hard oshayelayo. Basuke exhunywe kwi lamachweba akhanga izivakashi zangaphandle sekhompyutha - kunazo zonke-USB noma FireWire. ukusebenza yabo ngokuvamile elifana ephawula yangaphakathi lwedivayisi. Hard sediski okuqondene isigaba wangaphandle, njengoba umthetho, kahle esikhulu - mayelana 500-1000 GB. Iqiniso lokuthi lolu hlobo idivayisi ngokuvamile lisetshenziselwa bahamba ngezinyawo besuka kwenye ikhompyutha kwenye esiningi idatha.

Kukhona nama-hard drive, aguqulelwe laptops. usayizi labo lincane kakhulu 'HDD ", eyenzelwe ukufakwa ngendlela" ideskithophu "ikhompyutha - 2.5 amayintshi. hard drive isivinini laptop - ngokuvamile 4200 noma 5400 ngomzuzu. Operating ngemoto efana ngokuvamile wasebenzisa Sata esibonakalayo. Elinesimo ukumelana ushintsho isikhundla, okuyinto okunengqondo uma kucatshangelwa imininingwane usebenzisa amanothibhuku.

Phakathi izinhlobo kunazo obusezingeni hard drive - SSDs. Basuke, isimiso, kungase kubhekwe njengokwelapha esihlukile amadivayisi, kusukela isakhiwo yabo ayinakho amapuleti ezihambayo. Idatha kulolu hlobo hard disk oshayelayo zilotshiwe flash inkumbulo. Amadivayisi yalolu hlobo babe kokubili ngebuhle nebubi.

Abaningi ehola abakhiqizi PC emhlabeni ezibhekwa ukujwayeza imboni yabo imigqa ukwenziwa amadivayisi, yona ifakwe isimo ngemoto okuqinile. Lolu hlobo lwe-hard drive, ibiza amaningi kunalawo isakhiwo lapho amalunga ujikelezisa abakhona. Nokho, uma iqhathaniswa nayo them they zinezikhathi low power ukusetshenziswa, cishe ukungabi ingqikithi umsindo emsebenzini, futhi livela ezimweni eziningi - isisindo kancane. Isihlobo ukuba ijubane yokudlulisela idatha kungenzeka uphawulile ukuthi kunezimiso izinga ejwayelekile okuqinile-isimo hard drive - 300-400 MB / sec, okuyinto ehloniphekile ku isizinda amazinga zokuxhumana ehola kusekelwa amakhompyutha zanamuhla.

interface

ukufakwa ngempumelelo kwezinyathelo idrayivu kanzima e-PC incike khona interfaces edingekayo. Cabanga imininingwane yalolu amazinga ezivamile zokuxhumana emakethe imishini computer. Lokhu kuyoba usizo for ngokuqhathanisa imisebenzi umsebenzisi kanye nohlobo "idrayivu kanzima", okuyinto basuke ngokufanele ezifaneleke babahlangabeze.

Phakathi interfaces ezijwayeleke kakhulu yokuxhuma wangaphandle hard ngemoto - USB. Ngakho asebenzayo zokuxhumana ezijwayelekile kungenziwa okwethulwa izinguqulo ezihlukene - 1, 2, no-3 Ijubane disk hard kuyinto encike ngqo kwi kwedivayisi yayo nge ubuchwepheshe efanele. Ngokuphathelene version 1st kokusetshenziswa kubonwa, ungasho ukuthi uma isetshenziswa ukudlulisa idatha ku-12 Mbits / umzuzwana, kuqinisekisa 2nd ifayela ukwabelana ngesivinini esingafinyelela ku-480 Mbit / s, 3 kwesizukulwane-USB isikhombimsebenzisi unikeza inkomba ukuze 5 Gbit / s. Uma uhlose ukusebenzisa kudivayisi akusho kuphela amafayela, kodwa futhi, isibonelo, ukufaka imidlalo noma izinhlelo, kungcono uma iwukuhlale wamanje USB interface - kule nguqulo 2nd, futhi ezingcono nakakhulu lwesithathu.

ikhompyutha wangaphandle hard drive kungabuye ixhunywe nge isikhombikubona FireWire. It libhekene okusezingeni eliphezulu idatha isilinganiso - 400 Mbit / sec. Kuyinto ngempumelelo kakhulu lapho esebenza isiqophi amafayela.

Cabangela izindinganiso esetshenziswa uma ufaka ngemoto yangaphakathi e uhlobo PC. Kubhekwe esibonakalayo kuqhathaniswa esiphelelwe isikhathi, kodwa namanje ethandwa - IDE.

Kungaba ukudlulisa idatha ngesivinini mayelana 133 MB / sec. Common e ideskithophu PC - ngokuyinhloko ngenxa lemali kunalokho enkulu nezixhumi okungelona le-elilungile kwesakhiwo laptop isakhiwo.

Sata esibonakalayo - umphumela ekuthuthukiseni izinga IDE. It ikuvumela ukudlulisa idatha ngesivinini esingafinyelela ku-300 MB / sec. It libhekene amasosha omzimba okusezingeni eliphezulu sokungahloniphi. Kabanzi amakhompyutha notebook - sibonga ubukhulu elincane isixhumi, kanye nesilinganiso omuhle idatha.

SCSI esibonakalayo, njengoba sibonile ngenhla, ibekwe ikakhulu amaseva. Futhi ngezimiso eziphakeme idatha isilinganiso - mayelana 320 MB / sec. Kukhona ukuguqulwa ethuthukisiwe esibonakalayo yokubika - SAS. HDDs ukuthi usebenze ngaphansi ukubandakanyeka yayo ungahlinzekela idatha exchange ku oda 12 GB / s izinga.

Indlela ukukhetha idrayivu kanzima

Interface Imininingwane esixoxe ngayo ngasenhla kubhekwe njengento ebalulekile lapho ekhetha hard drive. siphinde ephakanyiswe eziningi nezinye nemingcele ezibalulekile - ezifana ijubane ukujikeleza izakhi devaysa Isici sefomu. Kodwa cishe, isici esibalulekile lapho ukhetha imodeli elilungile devaysa isici - hard disk inkumbulo. Ngezindlela eziningi, lokhu kukhetha subjective - abasebenzisi abaningi bakhetha ngokushesha "hard drive" kunaleyo lapho sizokwazi ukubeka inombolo enkulu amafayela. Nokho, hard disk umthamo - namanje into yokuqala banake abasebenzisi eziningi.

I isici esibaluleke kunazo kukhethwa "Winchester" - ezinye zezici zalo okuzisholo (isib kwedivayisi nalaba noma ezinye interface) kufanele kube iyahambisana amakhono okuxhumana we-PC. Kuqondane ukuthi kukhompyutha idrayivu kanzima Liyindawo nezobuchwepheshe, kodwa ukwesekwa ezindinganisweni olufanele kwi PC umbadlana enganele. Cabanga ezicashile ayisihluthulelo kwedivayisi "ngemoto" futhi ezinye izingxenye hardware lwamakhompyutha yesimanje.

Ubukhulu Okubalulekile ukuhambisana

Ngenhla sibonile ukuthi hard drive ayahluka ngobukhulu. Kungase kubonakale sengathi lokhu ipharamitha - ezincane. Kodwa ngokuvamile ke kuvela ukuthi cishe juqu. Iqiniso ukuthi ukufakwa kwe-disk kanzima e-PC yakho naku laptop yakho endaweni efanele kuyoba nzima kakhulu, uma usayizi wesitoreji lincane kakhulu, futhi ngenxa yalokho sub-elilungile ngokuya ukusetshenziswa isikhala esitholakalayo ku devaysa isakhiwo. Kungaba nzima uma Ubukhulu zinkulu kakhulu - "hard drive" omane angena computer.

Yiqiniso, nalesi sibonelo akugcini ejwayelekile ngokuyinhloko for laptops, njengoba izinkinga nokubekwa disk hard e PC "ideskithophu" ngokuvamile asivelanga (kubangelwe ukutholakala izesekeli ahlukahlukene mawuthanda). Ngakho-ke, uma uhlela ukuthenga idrayivu entsha kanzima laptop yakho, udinga ukwazi ukuthi ubukhulu esiqondile zamanje. Ngenhla sibonile ukuthi ezivamile "hard drive" factor uhlobo 2.5 amasentimitha izinhlobo abafanele lwamakhompyutha. Kodwa kufanele sikhumbule ukuthi hard drive 1.8 amayintshi setha kwezinye amamodeli we-laptop.

ukuxhumana Ihambisana amazinga

Ukuhambelana kufanele futhi zokuxhumana futhi "hard drive" interface PC umbadlana. The main caveat lapha - umehluko ku izinguqulo namazinga ukushintshanisa kwe-data. Ngakho, kukhona ezintathu yencwajana Sata esibonakalayo. Kubalulekile ukuthi indinganiso nezokuxhumana ezifanele kusekelwa esitolo, kwaba kuyavumelana futhi umbadlana. Kungase kwenzeke ukuthi umsebenzisi othenga i ezibizayo, kuqinisekisa exchange of idatha ku wamanje ejwayelekile Sata 3 drive kanzima (intengo onobuhle okunjalo kungaba emhlabeni izinkulungwane 10. Deda.), Kodwa ikhompyutha ingeke bakwazi ukweseka ngokugcwele. umnikazi PC, ngaleyo ndlela, kungaba ngokuphawulekayo overpay.

Kungokufanayo uya for ukuhlanganisa asekelwe ngezindinganiso "hard disk" futhi PC-USB. Uma drive kanzima yakhelwe ukuxhuma nge-USB esibonakalayo 3.0, kodwa umbadlana ayisekeli ke, amakhono kwezobuchwepheshe namazinga afanele futhi ngeke baqaphela ngokugcwele. Ngokuphathelene esibonakalayo FireWire, ungasho ukuthi ukuthenga ukwesekwa yayo hard disk (kudivayisi intengo kungaba futhi ehloniphekile - .. ruble ayizigidi 8-10), kumelwe siqinisekise ukuthi PC yakho isimiso iyahambisana ke. Le ndinganiso zokuxhumana kuyinto ejwayelekile laptops, kodwa engekho e-PC amaningi "ideskithophu." Yiqiniso, nama-hard drive, FireWire ukwesekwa, njengoba umthetho, ngenkathi futhi iyahambisana USB interface, futhi Mancane kakhulu amathuba okuthi idivayisi kuyoba non-functional ngenxa yokuntuleka port FireWire kwi-PC. Kodwa uma umsebenzisi, isibonelo, kulindeleke ukuba zihilela ezisobala kakhulu inzuzo yokuncintisana ka FireWire - ukusebeza kahle idatha video, ngeke uthole imiphumela oyifunayo idrayivu kanzima.

Inani elikhulu

Njengoba siphawulile ngenhla, ivolumu njengoba izici eyinhloko leli thuluzi, njengomuntu hard drive - lokhu liyipharamitha subjective kakhulu. Abasebenzisi abaningi kwanele, ake sithi, a gigabytes ambalwa sediski - isibonelo, uma zisebenza ngokuyinhloko imibhalo. Othile futhi hard drive itherabhayithi kubonakala evulekile ngokwanele ukuphoqelela ukuthunyelwa njalo lemiqulu emikhulu kokuqukethwe multimedia - amavidiyo, izithombe, umculo.

Luncoma lemali kahle isitoreji kunzima. Kodwa umqondo welithi "kulapho - ngcono" - akuyona njalo ukhetho best, futhi kusukela iphuzu kwezomnotho umbono. Ungakwazi ukuchitha endleleni, drive enkulu kanzima - 1TB. Lonke itherabhayithi Ngakho etholakalayo - kodwa umkhuba ingasetshenziswa cishe isigamu. Kulokhu uma uthenga capacious kancane, kodwa idrayivu emi izimali eshibhile ezikhishwe ingasetshenziswa ukuthuthukisa ukusebenza PC yakho naku laptop (isibonelo, ukuthenga eyengeziwe RAM module noma kuyabanda enamandla okwengeziwe wokugaya).

Ngokusho eziningana IT-ongoti, idrayivu kanzima 500 GB - ikhambi elikhulu iningi imisebenzi umsebenzisi. Ngakho, kwi "hard drive" umthamo elihambisana zingafakwa ecishe ibe yizinkulungwane 100-150. Izithombe izinga ezinhle, ukufaka 100-150 imidlalo yesimanje. Uma umnikazi PC - hhayi fotoshedevrov ngalendoda hhayi ungumdlali, akunakwenzeka ukuba iqashe okungenani isigamu yomthombo okuhambisanayo. Kodwa-ke amathuba ayinike disk hard of 500 GB, ungakwazi ngempela esanele uma yena, unesithakazelo izithombe nemidlalo. Nokho, inani "idrayivu kanzima" ubhekwa njengomunye best ngokuya imisebenzi evamile ukuxazulula abasebenzisi eziphambili.

ijubane ukujikeleza

Enye ipharamitha ezibalulekile ephawula hard drive - izinga inzuzo amapuleti. Mayelana kungashiwo ukuthi kubalulekile kusukela umbono langempela ukudluliswa kwedatha rate kanye yesistimu yokusebenza esiphatha Dynamics amafayela ahlukahlukene. Uma "drive kanzima 'lisetshenziswa njengophawu main, okungukuthi, kuyafaneleka egijima, it efakwe izinhlelo nemidlalo, kungcono uma sicabangela izici siyofezwa inqwaba ngangokunokwenzeka. Uma umsebenzisi uthenga yesibili hard drive, yayiklanyelwe ukugcina amafayela, ngalo mqondo ijubane ukujikeleza amapuleti - hhayi kuyinkomba ebaluleke kakhulu.

Ayanda ukubaluleka le nkomba, isitoreji ezibizayo. Ngalo mqondo, le ngokweqile isivinini ephakeme naphezu kweqiniso lokuthi yobukhona babo kungadingeki, kungenzeka, futhi, kube engathandeki. "Winchester" nge speed ukujikeleza disk likhipha umsindo kakhulu engaphezu kweyodwa ejika zinesizotha futhi libhekene okusezingeni eliphezulu amandla ukusetshenziswa. Izinga eliphezulu yesimanje angaphandle kanzima, lapho kungenzeka isinqumo ephumelelayo iningi imisebenzi umsebenzisi - 7200 ngomzuzu.

inkumbulo Inqolobane

Phakathi izinkomba abalulekile drive ukusebenza - isilondolozi. Ngebhayisikili le nsiza, drive kanzima angakwazi kakhulu kusheshiswe izinqubo ukwenza imisebenzi eminingi ngamafayela. Isilondolozi usulungise njalo kunazo nombuzo algorithms izinsiza ezithile kukhompyutha yakho. Uma ezinye idatha ku isilondolozi, i- "Winchester" asikho isidingo ukuzibheka esikhaleni RAM noma phakathi amafayela. I emikhulu isilondolozi, ngcono. Kodwa ochwepheshe abaningi Kunconywa ukubaluleka elikhulu elihambisana Inkomba - 64 MB.

Ingabe umkhiqizo kubalulekile?

Ingabe kunengqondo ukuba ukhethe hard drive, zonke ezinye izinto ukuba alingane, ukugxila brand? Imibono IT-ochwepheshe kanye nabasebenzisi kule ndaba ihlukile kakhulu. Lokhu kusebenza kokubili izincomo ukugxila brand, futhi amaphuzu umbono izinga ngemoto ekhiqizwa ngabakhiqizi ethize. Abanye abasebenzisi kuyakuba izimpawu ezinhle zalo kakhulu, ezikhishwe Samsung, hard drive izibuyekezo ezivela kwamanye abanikazi devaysa brand-Korean singaba sincane ngomdlandla. Ezinye IT-ochwepheshe adunyiswe brand Hitachi, Toshiba, abanye musa ababheke njengezinto okuthile okungcono kunamadodana mncintiswano. Nokho, lezi zinkampani - abaholi emakethe. Leli qiniso, noma kunjalo, kufanele sithathwe njengehlelo abalulekile. Isimo umholi emakethe ukuncintisana kakhulu computer izesekeli akuveli lula. Cishe Lokhu kunomthelela izinga okusezingeni bezimpahla ezikhiqiziwe.

Ngakho, uma sidinga drive kanzima PC noma laptop, singakwazi uholwe elandelayo zindlela:

- usayizi (ezibalulekile ikakhulukazi ngoba laptops - akuyona efiselekayo ukuthi lesi sibalo okuhambisanayo kwaba esingaphansi Slots bathole amahholo hard drive, akuvumelekile - ukuthi yayinkulu);

- amazinga asekelwe (kubalulekile ukuthi interface zobuchwepheshe kwi "hard drive" kukhona kuyahambisana ngokugcwele PC imithombo);

- Umthamo (subjective, kodwa 500GB - inkomba kangcono iningi imisebenzi umsebenzisi);

- amapuleti isivinini (elikhulu - 7200 ngomzuzu);

- isilondolozi inkumbulo (ngokufanele - 64 MB).

Libuye efiselekayo ukuthi "hard drive" kwakhululwa ngumkhiqizi, eye ehola izikhundla emakethe izwe ingxenye efanele zedivayisi.
