Sanibonani
I-hard disk (ngemuva kwalokhu ebizwa nge-HDD) ngenye yezingxenye ezibaluleke kakhulu kunoma iyiphi ikhompyutha noma i-laptop. Wonke amafayela abasebenzisi agcinwe kwi-HDD futhi uma eshayisa, khona-ke ukubuyiselwa kwamafayela kunzima impela futhi akwenzeki ngaso sonke isikhathi. Ngakho-ke, ukukhetha i-hard drive akuyona enye yemisebenzi elula (ngingasho nokuthi ingxenye ethile yenhlanhla ayinakwenziwa).
Kulesi sihloko, ngithanda ukukhuluma ngolimi "olulula" mayelana nawo wonke amapharamitha ayisisekelo we-HDD okudingeka awunake uma uthenga. Futhi ekugcineni kwendatshana ngizonikeza izibalo ngokuya ngesipiliyoni sami ekuthembekeni kwemikhiqizo ethile yokushayela kanzima.
Futhi ngakho-ke ... Uza esitolo noma uvula ikhasi kwi-Intanethi ngokunikezwa okuhlukahlukene: Izinhlobo eziningi zemikhiqizo yokushayela kanzima, enezifinyezo ezihlukile, ngamanani ahlukile (noma ngabe kunevolumu efanayo ku-GB).
Cabanga ngesibonelo.
I-HDD Seagate SV35 ST1000VX000
I-1000 GB, i-SATA III, i-7200 rpm, i-156 MB, i-cache - i-64 MB
I-Hard drive, i-brand Seagate, ama-intshi angama-3.5 (ama-2,5 asetshenziswa kuma laptops, mancane ngosayizi. Ama-PC asebenzisa ama-intshi ayi-3.5), anomthamo we-1000 GB (noma i-1 TB).
I-Seagate Hard Drayivu
1) i-Seagate - umakhi wediski elukhuni (mayelana nemikhiqizo ye-HDD futhi iyiphi ethembekile kakhudlwana - bheka ezansi kwendatshana);
I-2) I-1000 GB yivolumu yedrayivu enzima eyenziwe ngumenzi (ivolumu yangempela incane kancane - cishe i-931 GB);
3) I-SATA III - isikhombimsebenzisi sokuxhuma idiski;
4) i-7200 rpm - ijubane le-spindle (kuthinta ijubane lokushintshana kolwazi nge-hard drive);
5) 156 MB - isivinini sokufunda kusuka kudiski;
6) 64 MB - Inkumbulo ye-Cache (buffer). Kukhulu i-cache, okungcono!
Ngendlela, ukuyenza icace ukuthi yikuphi okusengozini, ngizofaka isithombe esincane lapha ngedivaysi ye- "yangaphakathi" ye-HDD.
I-Hard drive ngaphakathi.
Ukucaciswa kwe-Hard drive
Isikhala sediski
Isici esiyinhloko se-hard drive. IVolumu ilinganiswa kuma-gigabyte nama-terabytes (ngaphambili, abantu abaningi bebengawazi lawo magama): I-GB ne-TB, ngokulandelana.
Isaziso esibalulekile!
Abakhiqizi be-Disk bakopela lapho bebala inani lediski enzima (babale ngamanani, nekhompyutha in kanambambili). Abasebenzisi abaningi be-novice abayazi isibalo esinjalo.
Kwidiski eqinile, ngokwesibonelo, ivolumu emenyezelwe umenzi ingu-1000 GB, empeleni, ubukhulu bayo bangempela bungu-931 GB. Ngani?
I-1 KB (kilo-byte) = 1024 Bytes - lokhu kumqondo (iWindows izoyicabangela);
1 KB = 1000 Bytes yilokho abakhiqizi be-hard drive abacabangi.
Ukuze ungathwali izibalo, ngizokusho ukuthi umehluko phakathi kwevolumu yangempela neyamenyezelwayo imayelana ne-5-10% (ubukhulu bomthamo wediski - mkhulu umehluko).
Umthetho oyisisekelo lapho ukhetha i-HDD
Lapho ukhetha i-hard drive, ngombono wami, udinga ukuqondiswa ngumthetho olula - "asikho isikhala esiningi futhi enkulu kangakanani i-drive, okungcono!" Ngikhumbula isikhathi, eminyakeni eyi-10-12 eyedlule, lapho i-hard drive eyi-120 GB yabonakala inkulu. Njengoba kwenzeka, bekuvele kunokushoda kwayo ezinyangeni ezimbalwa (yize-ke bekungekho i-Intanethi engenamkhawulo ...).
Ngamazinga wanamuhla, idrayivu engaphansi kwama-500 GB - 1000 GB, ngombono wami, akufanele futhi icatshangwe. Isibonelo, izinombolo eziphambili:
- 10-20 GB - ukufakwa kohlelo lokusebenza lweWindows7 / 8 kuzothatha;
- 1-5 GB - iphakethe le-Microsoft Office elifakiwe (kubasebenzisi abaningi le phakethe liyadingeka ngokuphelele, futhi sekuyisikhathi eside lithathwa njengeyisisekelo);
- 1 GB - cishe iqoqo elilodwa lomculo, njenge- "100 yezingoma ezinhle kakhulu zenyanga";
- I-1 GB - i-30 GB - kuthatha umdlalo owodwa wesimanje wekhompyutha, njengomthetho, abasebenzisi abaningi banemidlalo ethile abayintandokazi (nabasebenzisi kwi-PC, imvamisa abantu abaningana);
- 1GB - 20GB - indawo ye-movie eyodwa ...
Njengoba ukwazi ukubona, ngisho ne-1 TB yediski (1000 GB) - ngezidingo ezinjalo izoba matasa ngokushesha ngokwanele!
Isixhumi sokuxhuma
I-Winchesters yehlukile hhayi ngevolumu nophawu kuphela, kepha futhi nesixhumi sokuxhuma. Cabanga okuvame kakhulu namuhla.
I-Hard Drive 3.5 IDE 160GB WD Caviar WD160.
IDE - esivele isikhombimsebenzisi esithandwayo sokuxhuma amadivaysi amaningi ngokufana, kepha namuhla sekuphelile. By the way, my hard drive drives ne-IDE interface isasebenza, kanti amanye ama-SATA asevele eye emhlabeni ongalungile (yize benginaka kakhulu ngabo bobabili).
I-1Tb Western Digital WD10EARX Caviar Green, SATA III
I-SATA - I-interface yesimanjemanje yokuxhuma amadrayivu. Ukusebenza ngamafayela, ngalesi sixhumanisi sokuxhuma, ikhompyutha izoshesha kakhulu. Namuhla, isilinganiso se-SATA III (i-bandwidth engaba ngu-6 GB / s) isebenza, ngendlela, sinokubuyela emuva emuva, ngakho-ke, ithuluzi elisekela i-SATA III lingaxhunywa ethekwini le-SATA II (yize ijubane lizoba eliphansi).
IVolumu ye-Buffer
Isidlali (kwesinye isikhathi esibizwa nje ngokuthi i-cache) yinkumbulo eyakhelwe kwi-hard drive esetshenziselwa ukugcina idatha ikhompyutha efinyelela kakhulu kuyo. Ngenxa yalokhu, ijubane le-disk liyenyuka, ngoba akudingeki ukuthi ifunde njalo le datha kusuka kudiski kazibuthe. Ngakho-ke, lapho kukhulu i-buffer (i-cache) - ngokushesha i-hard drive izosebenza.
Manje kuma-hard drive, i-buffer ejwayelekile kakhulu ngosayizi kusuka ku-16 kuye ku-64 MB. Vele, kungcono ukukhetha eyodwa lapho i-buffer inkulu khona.
Ijubane le-Spindle
Leli ipharamitha lesithathu (ngombono wami) okudingeka unake kakhulu. Iqiniso ngukuthi ijubane le-hard drive (nekhompyutha iyonke) kuzoncika ijubane le-spindle.
Ijubane elikhulu kakhulu lokujikeleza I-7200 rpm ngomzuzu (imvamisa, sebenzisa amagama alandelayo - 7200 rpm). Nikeza ibhalansi ethile phakathi kwesivinini somsebenzi nomsindo wediski (ukufudumeza).
Kaningi kuvama amadiski ngejubane lokushintshana 5400 rpm - ziyahlukahluka, njengomthetho, ekusebenzeni okuthulekile (akukho msindo owengeziwe, indlakadla lapho zihambisa amakhanda kazibuthe). Ngaphezu kwalokho, ama-disc anjalo asha kancane, okusho ukuthi awadingi ukupholisa okwengeziwe. Ngiphawula nokuthi amadiski anjalo athatha amandla amancane (yize kuyiqiniso ukuthi umsebenzisi ojwayelekile uyathanda na ipharamitha).
Kusanda kuvela ama-disc ngesivinini Ukuvukelwa okungu-10,000 ngomzuzu. Zikhiqiza kakhulu futhi zivame ukufakwa kumaseva, kumakhompyutha anezidingo eziphezulu kuhlelo lwediski. Intengo yama-disc anjalo iphakeme impela, futhi ngombono wami, ukufaka i-disc enjalo kukhompyutha yasekhaya akusasebenzi kangako ...
Namuhla kuyathengiswa, ikakhulukazi izinhlobo ezingama-5 zokushayela ngokushayela okukhulu: i-Seagate, i-Western Digital, iHitachi, iToshiba, i-Samsung. Akunakwenzeka ukusho ngokungananazi ukuthi uluphi uhlobo lomkhiqizo oluhamba phambili, futhi nokubikezela ukuthi imodeli ethile izokusebenzela isikhathi esingakanani. Ngizoqhubeka nokususelwa kulwazi lwami uqobo (angithatheli noma yiziphi izilinganiso ezizimele).
I-Seagate
Omunye wabakhiqizi abaziwa kakhulu bokushayela kanzima. Uma ukuthatha wonke, khona-ke phakathi kwawo womabili amaqembu aphumelele ama-disk, futhi hhayi kangako. Imvamisa, uma ngonyaka wokuqala wokusebenza i-disc ingaqali ukubhoboka, khona-ke izohlala isikhathi eside impela.
Isibonelo, ngine-Seagate Barracuda 40GB 7200 rpm IDE drive. Useneminyaka ecishe ibe ngu-12-13 ubudala, noma kunjalo, usebenza okukhulu, njengokusha. Akuqhekeki, akunantethe, isebenza ngokuthula. Ukubuyisa okuwukuphela kwesikhathi ukuthi isiphelelwe isikhathi, manje i-40 GB yanele kuphela kwi-PC yehhovisi enomsebenzi omncane (empeleni, le PC lapho itholakala khona manje imatasa).
Kodwa-ke, ngokwethulwa kwe-Seagate Barracuda 11.0, le modeli ye-drive, ngokubona kwami, iye yonakala kakhulu. Kaningi kuba nezinkinga nabo, uqobo lwami ngingeke ngincome ukuthatha "i-barracuda" yamanje (ikakhulukazi njengoba "benza umsindo omningi") ...
Imodeli ye-Seagate Constellation ithola ukuthandwa - ibiza izikhathi eziphindwe izikhathi ezimbili kuneBarracuda. Izinkinga nazo zivame kakhulu (mhlawumbe zisaqala ...). Ngendlela, umenzi unikeza isiqinisekiso esihle: kuze kube izinyanga ezingama-60!
Idijithali yaseNtshonalanga
Futhi enye yemikhiqizo edumile kakhulu ye-HDD etholakala emakethe. Ngokubona kwami, ukushayela kwe-WD kuyindlela engcono kakhulu yokufakelwa kwi-PC. Intengo ephakathi ayilona ikhwalithi eyanele, ama-discs anenkinga atholakala, kepha awaphansi kakhulu kune-Seagate.
Kukhona "izinhlobo" ezahlukahlukene zama-disc.
I-WD Green (eluhlaza okotshani, uzobona isinamatheli esiluhlaza kwicala le-disc, bheka isithombe-skrini ngezansi).
Lawa ma-disc ahlukile, ngokuyinhloko ngoba asebenzisa amandla amancane. Ijubane le-spindle lamamodeli amaningi liyi-5400 rpm. Ijubane lokushintshaniswa kwedatha lincane kancane kunelamadiski ane-7200 - kepha athule kakhulu, angabekwa cishe kunoma yikuphi amacala (noma ngaphandle kokupholisa okwengeziwe). Isibonelo, ngikuthanda ngempela ukuthula, kuhle ukusebenzela i-PC omsebenzi wayo ungezwakali! Ngokuthembekile, kungcono kune-Seagate (ngendlela, kwakungekho ukuphumelela kakhulu kwama-disc we-Caviar Green, yize mina angizange ngihlangane nabo).
Wd oluhlaza okwesibhakabhaka
Ukushayela okuvame kakhulu phakathi kwe-WD, ungafaka amakhompyutha amaningi we-multimedia. Bayisiphambano phakathi kwezinguqulo ze-Green and Black izinhlobo zama-disks. Ngokomthetho, zinganconywa i-PC ejwayelekile yasekhaya.
Mnyama
Ukushayela kanzima okuthembekile, mhlawumbe okuthembeke kakhulu phakathi komkhiqizo we-WD. Kuliqiniso, yizona ezimnandi futhi ezifudumele kakhulu. Ngingancoma ukufakwa kwama-PC amaningi. Kuliqiniso, kungcono ukungayisebenzisi ngaphandle kokupholisa okwengeziwe ...
Kukhona nemikhiqizo ebomvu, i-Purple, kodwa iqiniso, angihlangani nayo njalo. Ngeke ngithi ngenxa yokwethembeka kwabo okuthile okucacile.
Toshiba
Hhayi uhlobo oludumile kakhulu lokushayela kanzima. Kunomshini owodwa osebenzisana nale Toshiba DT01 drive - isebenza kahle, azikho izikhalazo ezikhethekile. Kuliqiniso, ijubane liphansi kancane kunele lemikhiqizo yeWD Blue 7200 rpm.
Hitachi
Ayithandwa njenge-Seagate noma i-WD. Kodwa ukukhuluma iqiniso, angikaze ngihlangane nama-diski kaHitachi (ngenxa yephutha lama-disks ngokwawo ...). Kunamakhompyutha amaningi anamadiski afanayo: asebenza buthule, kepha ayashisa. Inconyelwe ukusetshenziselwa ukupholisa okwengeziwe. Ngokubona kwami, ezinye ezinokwethenjwa kakhulu, kanye ne-WD brand brand. Kuyiqiniso, babiza kakhulu izikhathi eziphindwe izikhathi ezingama-1.5-2 kune-WD Black, ngakho-ke okuncono kungcono.
I-PS
Emuva ngo-2004-2006, uhlobo lweMaxtor lwaludumile impela, ngisho nokushayela okushayela izikhawu eziningana kwasala. Ukuthembela - ngaphansi "kokujwayelekile", iningi labo "kwandiza" ngemuva konyaka noma emibili ukusetshenziswa. Ngemuva kwalokho uMaxtor wathengwa yi-Seagate, futhi empeleni akukho okunye engingakusho ngabo.
Konke lokho. Uhlobo luni lwe-HDD olusebenzisayo?
Ungakhohlwa ukuthi ukuthembeka okukhulu kunakho konke - ukulekela. Konke okuhle!
