Njengezakhi eziningi zamakhompiyutha, ama-hard drive ashiyana ngezimpawu zawo. Amapharamitha anjalo athinta ukusebenza kwensimbi futhi anquma ukuvumelana kokusebenzisa kwayo ukwenza imisebenzi. Kulesi sihloko, sizozama ukukhuluma ngesici ngasinye se-HDD, sichaza ngokuningiliziwe umphumela nomthelela wabo ekusebenzeni noma kwezinye izinto.
Izici Key of Hard Drives
Abasebenzisi abaningi bakhetha i-hard drive, becinga kuphela ifomu layo levolumu kanye nevolumu. Le ndlela ayilungile ngokuphelele, ngoba ukusebenza kwensiza kuthintwa izinkomba eziningi eziningi, futhi kufanele unake zona lapho uthenga. Siphakamisa ukuthi uzijwayeze nezimpawu ezizothinta ngandlela thile ukuxhumana kwakho nekhompyutha.
Namuhla ngeke sikhulume ngamapharamitha wezobuchwepheshe nezinye izinto ze-drive okukhulunywa ngazo. Uma unentshisekelo ngalesi sihloko esithile, sincoma ukufunda izindatshana zethu ngazinye kusixhumanisi esilandelayo.

Isici sefomu
Enye yamaphuzu abathengi abhekene nabo usayizi wedrayivu. Izindlela ezimbili zithathwa njengezithandwayo - ama-intshi ayi-2,5 no-3.5. Amancane amancane avame ukufakwa kuma laptops, ngoba isikhala ngaphakathi kwecala lilinganiselwe, kanti ezinkudlwana zifakwa kumakhompiyutha omuntu agcwele usayizi. Uma ungafaki i-hard drive engu-3.5 ngaphakathi kwe-laptop, khona-ke i-2,5 ifakwe kalula esimweni sePC.
Kungenzeka uthole amakhono okushayela amancane, kepha asetshenziswa kuphela kumadivayisi eselula, ngakho-ke akufanele ubanake lapho ukhetha inketho yekhompyutha. Vele, ubukhulu be-hard drive bunqunyelwe hhayi kuphela isisindo nobukhulu bayo, kepha futhi nenani lamandla asetshenzisiwe. Kungenxa yalokhu ukuthi ama-HDD angama-intshi angu-2,5 asetshenziswa kakhulu njengezishayeli zangaphandle, ngoba anamandla anele anikezwe nge-interface interface (i-USB). Uma kuthathwe isinqumo sokwenza i-drive engu-3.5 yangaphandle, kungadinga amandla angeziwe.

Ivolumu
Okulandelayo, umsebenzisi uhlala ebheka ivolumu ye-drive. Ungahluka - 300 GB, 500 GB, 1 TB nokunye. Lesi sici sinquma ukuthi mangaki amafayela angalingana kwi-hard drive eyodwa. Ngalesi sikhathi, akusaluleki ukuthi uthenge amadivayisi anamandla angaphansi kwama-500 GB. Kuzoletha cishe ayikho imali (inani elikhulu lenza intengo ye-1 GB liphansi), kepha uma into edingekayo ingahle ingafanele, ikakhulukazi uma ubheka isisindo semidlalo nama-movie wesimanje ngokulungiswa okuphezulu.
Kuyasiza ukuqonda ukuthi ngesinye isikhathi intengo yediski ngayinye ye-1 TB ne-3 TB ingahluka kakhulu, lokhu kubonakala ikakhulukazi ngokushayela kwe-2-intshi. Ngakho-ke, ngaphambi kokuthenga kubalulekile ukunquma ukuthi yiziphi izinhloso i-HDD ezizohileleka ngayo nokuthi kungakanani cishe okuzofuneka kulokhu.

Ijubane le-Spindle
Ijubane lokufunda nokubhala ngokuyinhloko lihambisana nesivinini sokujikeleza kwe-spindle. Uma ufunda i-athikili enconyiwe ezingxenyeni zediski enzima, usuvele uyazi ukuthi izikhala kanye namapuleti ziyajikeleza ndawonye. Ukuguquguquka okuningana okwenziwa yilezi zinto ngomzuzu, kushesha bathuthela emkhakheni oyifunayo. Kulokhu kulandela ukuthi ngesivinini esikhulu kukhishwa ukushisa okwengeziwe, ngakho-ke, ukupholisa okuqinile kuyadingeka. Ngaphezu kwalokho, le nkomba ibuye ithinte nomsindo. Ama-HDD e-Universal, avame ukusetshenziswa ngabasebenzisi abajwayelekile, anejubane elisukela ekuguqukeni kwezinkulungwane ezi-5 kuye kwezi-10 ngomzuzu.
Ukushayela ngejubane le-5400 spindle kulungele ukusetshenziswa ezikhungweni ze-multimedia nakwamanye amadivayisi afanayo, ngoba ukugcizelela okuyinhloko ekuhlanganweni kwemishini enjalo kusetshenziswa amandla aphansi nokukhishwa komsindo. Amamodeli anesinkomba esingaphezu kwe-10,000 angcono ukudlula kubasebenzisi be-PC yasekhaya futhi abhekele i-SSD. Ngasikhathi sinye, i-7200 rpm izoba yigolide kubathengi abaningi abangaba khona.

Ukukhishwa kwejometri
Sisanda kusho ipuleti le-hard drive. Bayingxenye yejometri yedivayisi futhi kwimodeli ngayinye inani lamapulethi nobuningi bokurekhoda kubo buyahluka. Ipharamitha elibhekwayo lithinta zombili umthamo wesitoreji esiphezulu kanye nesivinini salo sokugcina / sokufunda. Okusho ukuthi, ulwazi lugcinwa ngqo kulawa mapuleti, futhi ukufunda nokubhala kwenziwa ngamakhanda. Idrayivu ngayinye ihlukaniswe ngemikhondo ye-radial, equkethe imikhakha. Ngakho-ke, kungumsakazo othinta ijubane lolwazi lokufunda.
Ijubane lokufunda lihlala liphakeme emaphethelweni epuleti lapho amathrekhi ede khona, ngenxa yalokhu, incane into ifomu, yehlisa ijubane esiphezulu. Izingcosana ezimbalwa zepuleti zisho ukushuba okuphezulu, ngokulandelana, kanye nesivinini esithe xaxa. Kodwa-ke, ezitolo eziku-inthanethi nakuwebhusayithi yomkhiqizi akuvezi ukukhombisa lesi sici, ngoba kulokhu ukukhetha kuba nzima kakhulu.
Isixhumi sokuxhuma
Lapho ukhetha imodeli yediski eqinile, kubalulekile ukwazi ukuxhumeka kwayo koxhumo. Uma ikhompyutha yakho ingeyesimanjemanje, kungenzeka ukuthi izixhumi kakhulu zeSATA zixhunywe kubhodi yomama. Kumamodeli amadala wokushayela angasasebenzi, i-IDE yasetshenziswa. I-SATA inezibuyekezo eziningana, ngayinye ihluka nge-bandwidth. Uhlobo lwesithathu luxhasa isivinini sokufunda nokubhala esifinyelela ku-6 Gb / s. Ukusetshenziswa kwasekhaya, i-HDD ene-SATA 2.0 (ishesha ifinyelela ku-3 Gb / s) yanele.
Kumamodeli abiza kakhulu, ungabona ukubonwa kwe-SAS. Isebenzisana ne-SATA, noma kunjalo, yi-SATA kuphela engaxhunywa kwi-SAS, hhayi okuphambene nalokho. Leli phethini lihlobene ne-bandwidth kanye ne-technology development. Uma ungabaza ukukhetha phakathi kwe-SATA 2 no-3, zizwe ukhululekile ukuthatha inguqulo yakamuva, uma isabelomali sivuma. Iyahambelana neyangaphambilini ezingeni lezixhumi nezintambo, kepha yathuthukisa ukuphathwa kwamandla.

IVolumu ye-Buffer
Isilondolozi noma inqolobane isixhumanisi esiphakathi sokugcina imininingwane. Inikeza ukugcinwa kwedatha yesikhashana ukuze ngokuzayo lapho ufinyelela i-hard drive ibamukele khona manjalo. Isidingo sobuchwepheshe obunjalo siphakama ngoba isivinini sokufunda nokubhala sivame ukungafani futhi kukhona ukubambezeleka.
Kumamodeli anosayizi wamasentimitha angama-3.5, usayizi we-buffer uqala kusuka ku-8 futhi uphela ngama-megabytes ayi-128, kepha akufanele ngaso sonke isikhathi ubheke izinketho ezinezinkomba ezinkulu, ngoba i-cache ayisebenzi neze lapho kusebenza namafayela amakhulu. Kungaba okulungile ngokwengeziwe ukuthi uqale uhlole umehluko ekubhalweni nasekufundeni isivinini semodeli, bese-ke, ngokusekelwe kulokhu, sekunquma usayizi ophelele we-buffer.

MTBF
I-MTBF noma i-MTFB (Kusho Isikhathi Phakathi Kwehluleka) ibonisa ukuthembeka kwemodeli ekhethiwe. Lapho uvivinya i-batch, onjiniyela banquma ukuthi i-drive izosebenza isikhathi esingakanani ngaphandle komonakalo. Ngokufanelekile, uma uthenga idivaysi iseva noma ukugcinwa kwedatha isikhathi eside, qiniseka ukuthi ubheka le nkomba. Ngokwesilinganiso, kufanele ilingane namahora ayisigidi noma ngaphezulu.
Isikhathi sokulinda esimaphakathi
Ikhanda lihamba liye kunoma iyiphi ingxenye yethrekhi isikhathi esithile. Isenzo esinjalo senzeka ngokoqobo esihlukweni sesibili. Ukwehlisa ukubambezeleka, imisebenzi igcwaliswa ngokushesha. Kumamodeli e-universal, i-latency ejwayelekile yi-7-14 MS, neseva - 2-14.
Ukusetshenziswa kwamandla nokushisa
Ngaphezulu, lapho sikhuluma ngezinye izici, isihloko sokushisa nokusetshenziswa kwamandla sekuvele kuphakanyisiwe, kepha ngithanda ukukhuluma kabanzi ngalokhu ngokuningile. Kuliqiniso, kwesinye isikhathi abanikazi bamakhompiyutha bangayinaka ipharamitha yokusebenzisa amandla, kepha uma bethenga imodeli yelaptop, kubalulekile ukwazi ukuthi inani eliphakeme, ngokushesha ibhethri likhipha ngokushesha lapho kusebenza off-line.
Amanye amandla asetshenziswayo ahlala eguqulelwa ukushisa, ngakho-ke uma ungakwazi ukufaka ukupholisa okuthe xaxa ecaleni, kufanele ukhethe imodeli enenkomba ephansi. Kodwa-ke, ungazijwayeza amazinga okushisa okusebenza we-HDD kusuka kubakhiqizi abahlukahlukene kwesinye isihloko sethu kusixhumanisi esilandelayo.

Manje usuyayazi imininingwane eyisisekelo mayelana nezimpawu eziyinhloko zokushayela kanzima. Ngenxa yalokhu, ungenza ukukhetha okuhle lapho uthenga. Uma, ngenkathi ufunda i-athikili, uthathe isinqumo sokuthi kungayilungela kakhulu imisebenzi yakho ukuthenga i-SSD, sincoma ukuthi ufunde imiyalo ngalesi sihloko ngokuqhubekayo.
