Njengamalungu amaningi ekhompiyutha, ukushayela kanzima kuhluke ezimfanelweni zabo. Imingcele enjalo ithinta ukusebenza kwensimbi futhi inqume ukuthi kungenzeka kanjani ukusetshenziswa kwayo ukwenza imisebenzi. Kulesi sihloko, sizozama ukukhuluma ngesici ngasinye se-HDD, sichaza ngokuningiliziwe umphumela wabo nomthelela ekusebenzeni noma kwezinye izici.
Izici eziyinhloko zokushayela okunzima
Abasebenzisi abaningi bakhetha i-disk eyinkimbinkimbi, bacabangela kuphela ifomu lesimo salo nevolumu. Le ndlela ayilungile ngokuphelele, ngoba izinkomba eziningi eziningi zithinta ukusebenza kwedivayisi, nazo zidinga ukunaka lapho uthenga. Siphakamisa ukuthi uzijwayele izici ukuthi indlela eyodwa noma enye izothinta ukuxhumana kwakho nekhomputha.
Namuhla ngeke sikhulume ngemingcele yezobuchwepheshe nezinye izingxenye zedrayivu okucatshangwayo. Uma unesithakazelo kule ndaba ethize, sincoma ukufunda izihloko zethu ezikhethiwe kulezi zixhumanisi ezilandelayo.

Ifomu lesimo
Omunye wamaphuzu okuqala abathengi abhekana nawo ubukhulu be-drive. Amafomethi amabili abhekwa njengothandwayo - 2.5 no 3.5 amasentimitha. Amancane amancane avame ukufakwa kuma-laptops, ngoba isikhala ngaphakathi kwesikweletu sinqunyelwe, futhi amakhulu amakhulu afakwe kuma-computer amancane ajwayelekile. Uma ungafaki i-hard drive ye-3.5 ngaphakathi kwe-laptop, bese-ke 2.5 ifakwe kalula ku-PC.
Ungakwazi ukuhlangabezana nokushayela namasayizi amancane, kodwa asetshenziswa kuphela kumadivayisi eselula, ngakho-ke uma ukhetha inketho yekhompiyutha okufanele ungayiqapheli. Yiqiniso, ubukhulu besidiski esinzima abukali isisindo saso kanye nobukhulu bayo, kodwa futhi inani lamandla adliwe. Ngenxa yalokhu, ama-HDD angu-2.5-intshi asetshenziswa kakhulu njengamashayeli angaphandle, njengoba anamandla kuphela anikezwa nge-interface yokuxhumanisa (i-USB). Uma kunqunywe ukwenza i-disk yangaphandle ye-3.5, kungadinga amandla engeziwe.

Umbhalo
Okulandelayo, umsebenzisi ubheka njalo ivolumu yedrayivu. Kungaba okuhlukile - 300 GB, 500 GB, 1 TB nokuningi. Lesi sici sinquma ukuthi amafayela amaningi angangena kanjani kwi-disk eyodwa. Ngalesi sikhathi ngesikhathi, akusekho ngokuphelele ukucelwa ukuthenga amadivaysi anomandla angaphansi kuka-500 GB. Ngokungabikho ukulondoloza kuzokuletha (ivolumu eyengeziwe yenza intengo nge-1 GB engezansi), kodwa uma into edingekayo ingase ingahambisani, ikakhulukazi ngokucabangela isisindo semidlalo yanamuhla namabhayisikobho ngesinqumo esiphezulu.
Kuyafaneleka ukuqonda ukuthi ngezinye izikhathi intengo ngayinye ye-TB ne-3 TB ingahluka ngokuphawulekayo, lokhu kubonakala ngokukhethekile kuma-2.5-inch drive. Ngakho-ke, ngaphambi kokuba uthenge kubalulekile ukucacisa ukuthi yini i-HDD ezosetshenziswa futhi ukuthi ingakanani indawo ezoyithatha.

Isivinini se-spindle
Isivinini sokufunda nokubhala ngokuyinhloko sincike ekuvinjeni kokujikeleza kwe-spindle. Uma ufunde isihloko esinconywayo kwizingxenye zediski eyinkimbinkimbi, usuvele wazi ukuthi i-spindle kanye namacwecwe ajikeleza ndawonye. Okunye okuguqula lezi zakhi kwenziwa ngomzuzu, ngokushesha kuhamba emkhakheni oyifunayo. Kuvela kulokhu ukuthi ngejubane elikhulu ukushisa okukhulu kukhishwa, ngakho-ke ukupholisa okuningi kuyadingeka. Ngaphezu kwalokho, lesi sibonakaliso sithinta umsindo. I-HDD yonke, evame ukusetshenziselwa abasebenzisi abajwayelekile, abe nesivinini ebangeni kusuka ku-5 kuya kwezingu-10 000 ukuvuselelwa ngomzuzu.
Ukushayela ngejubane le-5400 le-spindle lilungele ukusetshenziswa kumaziko e-multimedia namanye amadivaysi afanayo, ngoba ukugcizelela okuyinhloko ekuhlanganiseni imishini enjalo kufakwe ekusetshenzisweni kwamandla aphansi kanye nokukhishwa komsindo. Amamodeli anesibonakaliso esingaphezu kuka-10,000 kungcono ukugwema abasebenzisi bama-PC ekhaya bese ubheka i-SSD. I-7200 r / m ngesikhathi esifanayo kuyoba yindoda yegolide kulabo abathengi abaningi.

Ukusebenza kweJomethri
Sivele sisho i-hard disk drive. Ziyingxenye ye-geometry yedivayisi futhi kumodeli ngayinye inani lamapuleti nobukhulu bokurekhoda kuzo kuyahluka. Ipharamitha elicatshangwayo lithinta kokubili ivolumu ephezulu yedrayivu kanye nesivinini sokugcina sokufunda / ukubhala. Okusho ukuthi ulwazi lugcinwe ngokuqondile kulezi zingqimba, futhi ukufunda nokubhala kwenziwa ngamakhanda. I-drive ngayinye ihlukaniswe ngamathrekhi omsakazo, ehlanganisa imikhakha. Ngakho-ke, yilapho irejista ethinta ijubane lokufunda ulwazi.
Ijubane lokufunda liphakeme njalo emaphethelweni epuleti lapho amathrekhi ahlala khona, ngenxa yalokhu, encane ifomu lesimo, ukwehlisa isivinini esiphezulu. Inamba encane yamacwecwe kusho ukuphakama okukhulu, ngokulandelana, kanye nesivinini esengeziwe. Noma kunjalo, ezitolo ze-intanethi nakwebhusayithi yomkhiqizi, lesi sici asibonakali kangako, ngenxa yalokhu, ukhetho luba nzima nakakhulu.
Isixhumanisi sokuxhuma
Uma ukhetha i-hard disk imodeli, kubalulekile ukwazi ukuxhuma kwesikhombikubona. Uma ikhompyutha yakho isimanje, kungenzeka ukuthi izixhumi ze-SATA zifakwe ebhodini le-motherboard. Kumamodeli asebekhulile amashayela angasakhiwa, isikhombimsebenzisi se-IDE sisetshenzisiwe. I-SATA inemibukiso eminingana, ngayinye ehlukile ku-throughput. Inguqulo yesithathu isekela ukufunda nokubhala ukuvinjelwa kuka-6 Gbps. I-HDD ne-SATA 2.0 (ijubane kuze kufike ku-3Gb / s) yanele ukusetshenziswa kwekhaya.
Ngamamodeli abizayo, ungabona isikhombimsebenzisi se-SAS. Ihambisana ne-SATA, kodwa i-SATA kuphela ingaxhuma ku-SAS, futhi hhayi ngokuphambene nalokho. Le iphethini ihlotshaniswa nokuthuthukiswa komkhawulokudonsa nokuthuthukiswa kobuchwepheshe. Uma ungabaza mayelana nokukhetha phakathi kwe-SATA 2 no-3, zikhululeke ukuthatha inguqulo yakamuva, uma kwenzeka isabelomali sivumela. Ihambisana nabangaphambilini ezingeni lezixhumi kanye nezintambo, noma kunjalo liye lathuthukisa ukuphathwa kwamandla.

Usayizi we-Buffer
I-buffer noma i-cache ibizwa ngokuthi isixhumanisi sendawo yokugcina ulwazi. Inikeza isitoreji sesikhashana sedatha ukuze esikhathini esizayo i-hard drive ikwazi ukuyithola ngokushesha. Isidingo sobuchwepheshe obusukayo ngoba ijubane lokufunda nokubhala lihlukile futhi kukhona ukubambezeleka.
Ngamamodeli ane Usayizi wamasentimitha angu-3.5, usayizi we-buffer uqala ngo-8 futhi uphela ngamamithabhisi angu-128, kodwa akufanele uhlale ubheka izinketho nge-index enkulu, ngoba i-cache ayisebenziswanga ngenkathi isebenza namafayela amakhulu. Kungaba ngcono kakhulu ukuhlola kuqala umehluko ngesivinini sokubhala nokufunda imodeli, bese-ke, ngokusekelwe kulokhu, sinquma usayizi we-buffer ophambili.

Isikhathi esiphakathi sokuhluleka
I-MTBF (Isikhathi Sesikhathi Phakathi Kokuhluleka) sibonisa ukwethembeka kwendlela ekhethiwe. Uma uhlola i-batch, abathuthukisi banquma ukuthi i-disc izosebenza isikhathi esingakanani ngaphandle kokulimala. Ngakho-ke, uma uthenga idivayisi yesitoreji noma isitoreji sedatha yesikhathi eside, qiniseka ukuthi ubuka le nkomba. Ngokwesilinganiso, kufanele ilingane namahora ayisigidi owodwa noma ngaphezulu.
Isikhathi sokulinda sesilinganiso
Inhloko ihamba kunoma iyiphi ingxenye yethrekhi isikhathi esithile. Lesi senzo senzeke ngesekhondi elilodwa kuphela. Okuncane ukulibaziseka, ngokushesha imisebenzi yenziwa. Emibonisweni yendawo yonke, isikhathi sokulinda sesilinganiso esingu-7-14 MS, futhi kumamodeli wevava - 2-14.
Amandla Nokushisa Okushisayo
Ngenhla, lapho sikhuluma ngezinye izici, isihloko sokushisa nokusetshenziswa kwamandla sekuvele sikhulisiwe, kodwa ngingathanda ukukhuluma ngakho ngokuningiliziwe. Yiqiniso, ngezinye izikhathi abanikazi bekhompuyutha bangase bangayinaki ipharamitha yokusebenzisa amandla, kodwa uma imodeli ithengwa nge-laptop, kubalulekile ukwazi ukuthi inani eliphakeme, ngokushesha ibhethri liphuma uma lingenayo amandla.
Amanye amandla asetshenziswe njalo aguqulwa ekushiseni, ngakho-ke uma ungakwazi ukubeka ukupholisa okwengeziwe kule ndaba, kufanele ukhethe imodeli ngokufunda okuphansi. Noma kunjalo, ukusebenza kwama-HDD okushisa okuvela kubakhiqizi abahlukene kungatholakala kwesinye isiqephu esixhumanisi esilandelayo.

Manje uyazi ulwazi oluyisisekelo mayelana nezici eziyinhloko zamashayeli asebenzayo. Ngenxa yalokhu, ungakhetha kahle uma uthenga. Uma ngesikhathi sokufunda kwalesi sihloko unqume ukuthi kungcono kakhulu imisebenzi yakho ukuthenga i-SSD, sikukwazisa ukuthi ufunde imiyalelo yalesi sihloko ngokuqhubekayo.
