Khetha i-hard drive. Iyiphi i-hdd ethembekile kakhulu, yimuphi umkhiqizo?

Usuku oluhle.

I disk hard (lapha ngemuva kwe-HDD) ingenye yezingxenye ezibaluleke kakhulu kunoma yikuphi ikhompyutha noma i-laptop. Wonke amafayela omsebenzisi agcinwe kwi-HDD futhi uma ehluleka, bese uthola ukurekhoda ifayela kunzima futhi akusebenzi ngaso sonke isikhathi. Ngakho-ke, ukukhetha i-disk eyinkimbinkimbi akuyona umsebenzi olula (ngingaze ngisho ngithi umuntu akakwazi ukwenza ngaphandle kwenhlanhla ethile).

Kulesi sihloko, ngingathanda ukukutshela ngolimi "olulula" mayelana nayo yonke imingcele esemqoka ye-HDD okudingeka uyiqaphele lapho uthenga. Futhi ekupheleni kwalesi sihloko ngizobalula izibalo ezisekelwe ekuhlangeneni kwami ​​ekuthembekeni kwamanani ahlukahlukene okushayela.

Futhi kanjalo ... Woza esitolo noma uvule ikhasi kwi-Intanethi ngezipesheli ezihlukahlukene: inqwaba yemikhiqizo yokushayela okunamandla, enezifinyezo ezahlukene, ngamanani ahlukene (ngisho naphezu kwesayizi efanayo ku-GB).

Cabangela isibonelo.

Seagate SV35 ST1000VX000 Hard Drive

I-1000 GB, i-SATA III, i-7200 rpm, i-156 MB, c, imemori yokugcinwa kwemfihlo - 64 MB

I-disk eyinkimbinkimbi, uphawu lwe-Seagate, ama-intshi angu-3.5 (2.5 lisetshenziswe kuma-laptops, amancane asayizi. I-PC isebenzisa ama-diski angu-3.5 amasenti) ngamandla ka-1000 GB (noma i-1 TB).

1) Seagate - umenzi we disk hard (mayelana nemikhiqizo ye-HDD nokuthi yiziphi ezinokwethenjelwa kakhulu - bheka phansi kakhulu kwalesi sihloko);

2) I-1000 GB iyisayizi yedrayivu eyinkimbinkimbi ememezelwe umenzi (ivolumu yangempela ingaphansi kancane - cishe ngo-931 GB);

3) I-SATA III - i-disk interface;

4) 7200 rpm - isivinini se-spindle (sithinta isivinini sokwabelana ngolwazi nge-hard disk);

5) 156 MB - funda isivinini kusuka ku disk;

6) 64 MB - Imemori yekhompiyutha (i-buffer). I-cache engcono kakhulu!

Ngendlela, ukuze uqhubeke uqonda lokho okushiwoyo, ngizofaka isithombe esincane lapha nge "i-HDD" idivayisi.

Izinhlamvu ze-Hard Drive

I-disk ikhono

Isici esiyinhloko sese disk hard. Umqulu ulinganiswa ngama-gigabytes naku-bytes (ngaphambili, abantu abaningi babengamazi amagama anjalo): GB ne-TB, ngokulandelana.

Inothi elibalulekile!

Ama-disk abamba ukukhohlisa lapho bebala ubukhulu be-disk eyinkimbinkimbi (babala esimisweni sesimiso se-decimal, kanye nekhompyutheni enambambili). Abasebenzisi abaningi be-novice abazi ukuthi lokhu kubalwa.

Ngesidiski esinzima, isibonelo, ivolumu ememezelwe ngumenzi ngu-1000 GB, eqinisweni, usayizi wayo wangempela cishe u-931 GB. Kungani

1 KB (ama-kilobytes) = 1024 ama-Bytes - lokhu kusekho (ukuthi iWindows izobala kanjani);

1 KB = ama-bytes angu-1000 ukuthi abakhiqizi be-hard drive bakholelwa kanjani.

Ukuze ungakhathazeki ngezibalo, ngizosho ukuthi umehluko phakathi kwevolumu langempela neyamemezelwa cishe cishe ku-5-10% (ekulula ivolumu yediski, umehluko omkhulu).

Umthetho oyinhloko lapho ukhetha i-HDD

Uma ukhetha i-hard drive, ngombono wami, udinga ukuqondiswa umthetho olula - "akusikho isikhala esiningi futhi i-disk enkulu, ngcono!" Ngikhumbula isikhathi, eminyakeni engu-10-12 eyedlule, lapho i-disk hard disk 120 GB ibonakala inkulu. Njengoba kwenzeka, kwakungenakwanele ukumkhumbula esikhathini ezinyangeni ezimbalwa (nakuba ngaleso sikhathi kwakungekho inthanethi engenamkhawulo ...).

Ngezindinganiso zanamuhla, i-disk engaphansi kuka-500 GB - 1000 GB, ngokombono wami, akufanele kucatshangelwe. Isibonelo, izinombolo eziyinhloko:

- 10-20 GB - kuzothatha ukufakwa kwesistimu yokusebenza yeWindows7 / 8;

- Iphakethe le-Microsoft Office elibhalisiwe ngo-1-5 GB (abasebenzisi abaningi badinga le phakheji, futhi sekuyisikhathi eside kuthathwa njengokuyisisekelo);

- 1 GB - cishe iqoqo elilodwa lomculo, njenge "izingoma ezingu-100 ezinhle zenyanga";

- 1 GB - 30 GB - iningi lomdlalo wekhompyutha lwanamuhla lithatha, njengomthetho, kubasebenzisi abaningi, imidlalo eminingana eyintandokazi (nabasebenzisi be-PC, ngokuvamile abantu abaningana);

- 1GB - 20GB - isikhala se-movie eyodwa ...

Njengoba ubona, ngisho ne-1 disk ye-TB (1000 GB) - ngezidingo ezinjalo kuyoba matasa ngokushesha!

Isixhumanisi sokuxhuma

Ama-winchesters ahlukile ngokuvolumu nomkhiqizo kuphela, kodwa futhi ku-interface yomxhumanisi. Cabanga okujwayelekile kakhulu kuze kube yimanje.

IDE - isikhombimsebenzisi esivele sithandwa kakhulu sokuxhuma amadivaysi amaningi nge-parallel, kodwa namuhla sesivele yisikhathi. Ngendlela, ukushayela kwami ​​kanzima ne-IDE isikhombimsebenzisi kusasebenza, kuyilapho ezinye ze-SATA sezivele seziye "ezweni elizayo" (nakuba beziqaphele kakhulu ngalabo nalabo).

SATA - Isixhumanisi sesimanje sokuxhuma imoto. Sebenzisa ngamafayela, nalesi sikhombimsebenzisi sokuxhuma, ikhompyutha izoba ngokushesha kakhulu. Namuhla, i-standard SATA III (umkhawulokudonsa we-6 Gbit / s), ngendlela, ine-backward compatible, ngakho-ke, idivaysi esekela i-SATA III ingaxhunyaniswa nechweba le-SATA II (nakuba isivinini siyobe sesincane).

Usayizi we-Buffer

I-buffer (ngezinye izikhathi bathi nje isilondolozi) imemori eyakhiwe kwi disk eyinkimbinkimbi esetshenziselwa ukugcina idatha ikhompyutha efinyelela kaningi kakhulu. Ngenxa yalokhu, ijubane le-disk landa, ngoba akudingeki lifunde njalo le data kusuka ku-magnetic disk. Ngakho-ke, i-buffer (i-cache) enkulu kakhulu-ngokushesha i-hard drive izosebenza.

Manje ngokushayela okunamandla, i-buffer evamile kakhulu, esukela ngobukhulu kusukela ku-16 kuya kuma-64 MB. Yiqiniso, kungcono ukukhetha okukodwa lapho isikhumbuzi sikhulu khona.

Isivinini se-spindle

Le parameter yesithathu (ngombono wami) okumele ikhokhwe kuyo. Iqiniso liwukuthi ijubane le-hard drive (kanye nekhomputha lonke) lizoxhomekeka ngejubane lokujikeleza kwe-spindle.

Isivinini sokujikeleza esiphezulu kunazo zonke 7200 izinguquko ngomzuzu (ngokuvamile, sebenzisa uphawu olulandelayo - 7200 rpm). Nikeza uhlobo oluthile lokulinganisela phakathi kwesisindo somsindo nesivunguvungu (evuthayo).

Kanti futhi kaningi kukhona ama-disks anejubane lokujikeleza. 5400 izinguquko - ziyahlukahluka, njengomthetho, emsebenzini othule kakhulu (azikho imisindo engavamile, i-rattle uma ihambisa izinhloko zamagnetic). Ngaphezu kwalokho, la ma-discs aphansi kakhulu, ngakho-ke ayidingi ukupholisa okungeziwe. Ngiphinde ngiqaphele ukuthi ama-disks anjalo adla amandla angaphansi (nakuba kuyiqiniso ukuthi umsebenzisi ovamile unentshisekelo kule parameter).

Ama-discs asanda kubonakala ngejubane lokujikeleza. 10,000 revolutions ngomzuzu. Zikhiqiza kakhulu futhi zivame ukufakwa kumavava, kuma-computer anezidingo eziphezulu ohlelweni lwe disk. Inani lentengo enjalo liphezulu kakhulu, futhi ngombono wami, ukubeka i-disc enjalo kumakhompyutha asekhaya akusekhona iphuzu elanele ...

Namuhla, ama-brand angu-5 wezinkinobho ezinzima alawula ukudayiswa: Seagate, Western Digital, Hitachi, Toshiba, Samsung. Akunakwenzeka ukusho ukuthi yiliphi uhlobo elihle kakhulu - akunakwenzeka, njengokuthi ukubikezela ukuthi lokhu noma lowo modeli kuzokusebenzela kangakanani. Ngizoqhubeka ngisekelwe ekuhlangenwe nakho kwakho (angithathi izilinganiso ezizimele ezibhekene ne-akhawunti).

Seagate

Omunye wabakhiqizi abadume kakhulu bezinkinobho ezinzima. Uma sithatha sonke, khona-ke zombili amaqembu aphumelelayo ama-disks, futhi angeke ahlangane phakathi kwabo. Ngokuvamile, uma unyaka wokuqala womsebenzi i-disk ingaqala ukuthulula kuyo, khona-ke iyohlala isikhathi eside kakhulu.

Isibonelo, ngine-Seagate Barracuda 40GB 7200 rpm IDE drive. Sekusele eminyakeni engama-12-13 ubudala, noma kunjalo, isebenza kahle njengoba entsha. Ayiphumeli, ayikho i-rattle, isebenza ngokuthula. Ukulimala kuphela ukuthi kungaphelelwa yisikhathi, manje i-40 GB yanele kuphela i-PC yehhovisi, enomsebenzi omncane (empeleni, cishe le PC ekhona manje isetshenziswa).

Kodwa-ke, ekuqaleni kweSeagate Barracuda 11.0 version, lo modeli we-disc, ngokombono wami, uye wehle kakhulu. Ngokuvamile, kunezinkinga kubo, ngokwami ​​angizange ngincoma ukuthatha i- "barracuda" yamanje (ikakhulukazi njengoba abaningi babo "benza umsindo") ...

Manje imodeli ye-Seagate Constellation ithola ukuthandwa - kubiza izikhathi ezibiza kabili kuneBarcucuda. Izinkinga zabo zivame kakhulu (mhlawumbe kusasa kakhulu ...). Ngendlela, umenzi unikezela isiqinisekiso esihle: izinyanga ezingafika ku-60!

I-digital digital

Futhi enye yemikhiqizo edume kakhulu ye-HDD etholakala emakethe. Ngombono wami, ukushayela kwe-WD kuyindlela engcono kakhulu yokufaka kwi-PC namuhla. Intengo ejwayelekile ngekhwalithi enhle kakhulu, ama-disks enkingeni atholakala, kodwa kaningi kakhulu kune-Seagate.

Kukhona "izinguqulo" ezihlukahlukene zama diski.

I-WD Green (eluhlaza, kwicala le-disc uzobona isitaki esiluhlaza, bheka umfanekiso wesithombe ngezansi).

Lezi diski zihlukile, ikakhulu ngoba zidla amandla angaphansi. Isivinini se-spindle sezinhlobo eziningi kunama-revolution angu-5400 ngomzuzu. Ijubane lokushintshaniswa kwedatha lincane kakhulu kunelezi-7200 zokushayela - kodwa zithule kakhulu, zingafakwa cishe noma yiliphi icala (ngisho ngaphandle kokupholisa okwengeziwe). Isibonelo, ngithanda ukuthula kwabo, kuyamnandi ukusebenza ku-PC, umsebenzi ongezwakalayo! Ngokuthembeka, kungcono kunaseSeagate (ngendlela, kwakungekho amaqoqo aphumelelayo ama-disk eCarviar Green, nakuba angizange ngizihlangabezane nami ngokwami).

I-Wd blue

Ukushayela okuvame kakhulu phakathi kwe-WD, ungafaka amakhompyutha amaningi e-multimedia. Ziyisiphambano phakathi kwezinguquko eziluhlaza okweGreen nezinguDiski. Empeleni, zinganconywa i-PC evamile yasekhaya.

I-Wd black

Ukushayela okuqinile okunokwethenjelwa, cishe okuthembekile kakhulu phakathi kwe-WD brand. Yiqiniso, yizona ezithokozile futhi zifudumele kakhulu. Ngiyakwazi ukuncoma ukufakwa kwama-PC amaningi. Iqiniso, ngaphandle kokupholisa okungcono kungcono ukungabeki ...

Kukhona futhi ama-Red and Purple brand, kodwa ukwethembeka, angiboni ngaso sonke isikhathi. Angikwazi ukusho lutho olukhonkolo mayelana nokuthembeka kwabo.

Toshiba

Akuyona uphawu oludumile kakhulu lwezinkinobho ezinzima. Kunomshini owodwa osebenza nale drive ye-Toshiba DT01 - isebenza kahle, azikho izikhalazo ezikhethekile. Yiqiniso, ijubane lomsebenzi liphansi kakhulu kunele-WD Blue 7200 rpm.

Hitachi

Akuyona ethandwa njengoSeagate noma i-WD. Kodwa, ngokusobala, angikaze ngibhekane ne-disk Hitachi ehlulekile (ngenxa yama-disks ngokwabo ...). Kukhona amakhompyutha amaningana ane disks afanayo: asebenza ngokuthula, nakuba efudumala. Kunconywa ukuthi usebenzise nokupholisa okwengeziwe. Ngombono wami, enye yezinto ezinokwethenjelwa kakhulu, kanye ne-WD Black brand. Yiqiniso, zibiza izikhathi ezingu-1.5-2 ezibiza ngaphezu kwe-WD Black, ngakho-ke lezi zinsuku zikhethwa.

PS

Esikhathini eside kude no-2004-2006, umkhiqizo weMaxtor wawuthandwa kakhulu, ngisho nezinsizakalo ezimbalwa ezisebenza ngokushayela. Ngokokwethenjelwa - ngaphansi kwe "isilinganiso", eziningi zazo "zahamba" emva konyaka noma ezimbili zokusetshenziswa. Khona-ke uMaxtor wathengwa nguSeagate, futhi akukho lutho olungakutshela ngakho.

Yilokho kuphela. Iyiphi brand ye-HDD oyisebenzisayo?

Ungakhohlwa ukuthi ukuthembela okukhulu kunika - isipele. Okuhle kakhulu!
