Chikamu I: Kuitwa
Fixed media or hard drive storage is a great and market market. Dhiyabhorosi yakaoma inokonzerwa nepamusoro-soro sevhareji inotungamirira kune maduku maduku emakiromita anenge akaenzana nekota. Nezvose zvakasiyana-siyana zvemotokari kunze uko pamusika, munhu anoenda sei pakusarudza gwara rakakodzera yekombiyuta yavo?
Kuwana gwara rakanaka kunowira pasi pakuziva zvaunoda mumotokari. Inoshanda here kutyaira kwekombiyuta? Iko kukwanisa zvose izvo zvinokosha here? Kana kuti inonzi aesthetics? Iyi ndiyo mitatu yakakosha yekutarisisa chero dhigori yedhizimusi pamusika. Tine tariro kuti mutungamiri uyu achakubatsira kuziva kuti ndezvipi zvezvinhu izvi zvine basa uye kuti ungazvitarisa sei kana uchitenga motokari yako inotevera .
Performance
Kugadzirwa ndiko kutengesa kwevanhu vakawanda kusarudza kutsvaga . Iko kunotonhora kwakaneta motokari kunobata zvakakwana zvose zvekombiyuta yako mabasa. Kushanda kwekutsvaga kwakasimba kunonyatsotsanangurwa nemhando yechina yenhengo dzekutya:
- Interface
- Rotational Speed
- Access Times
- Buffer Size
Interfaces
Ikozvino pane zvinyorwa zviviri zvakakosha zvinoshandiswa pamatokari akaoma emakombiyuta ega pamusika: Serial ATA (SATA) uye IDE (kana ATA). Panewo sangano reSCSI raive raishandiswa kare kune mamwe madhikiti ekushanda akakwirira asi izvi zvakabva zvadonhedzwa uye zvinowanzoshandiswa kusachengetedza seva.
IDE interfaces ndiyo inowanikwa yakawanda pane inowanikwa pamakombiyuta evanhu. Kune huwandu hwehuwandu hunowanika kuI IDE kubva paATA / 33 kusvika ATA / 133. Inowanzofambisa inotsigira kusvika kuATA / 100 yepamusoro uye inodzokera kumashure inoshandiswa nevekare. Nhamba iri mumutauro inoratidza huwandu hwegwendeti mu megabytes kwechipiri iyo interface inokwanisa kubata. Nokudaro, ATA / 100 inoshandiswa inogona kutsigira 100 MB / sec. Parizvino hakuna dambudziko rekukwanisa kukwanisa kuenderera mberi idzi, uye chero chinhu chinopfuura ATA / 100 hachidiwi.
Kune Multiple Devices
Chikuru chakakosha kusvika kuDI standard ndeyekuti inobata sei zvigadzirwa zvakawanda. Mutungamiri mumwe nomumwe we IDE ane 2 makirani ayo anogonawo kutsigira madivayiri maviri. Mutevedzeri anofanira kunge akakurumidza kuenderera mberi kune imwe nzira inononoka pane imwe nzira. Ichi ndicho chikonzero unoona 2 IDE chiteshi: chimwe chekutyaira uye chechipiri chekufambisa. Rimwe dhirairi rakaoma uye optical drive pamusana iwoyo zvinokonzera kuti mutungamiriri achidzokorora zvakare kushanda kwayo optical drive speed iyo inoshatisa kushanda kwebasa rakaoma.
Serial ATA
Serial ATA ndiyo inoshandiswa mutsva uye inokurumidza kuisa IDE kumatokisi akaoma. Iyo iri nyore kushandiswa inoshandisa kamwe kambo pamusara uye inokurumidza kubva kubva 150 MB / s kusvika ku 300 Mb / s yezvinyorwa zvitsva. Kuti uwane mamwe mashoko pamusoro pekubatanidza uku, ona serial yangu yeAerial article .
Ikufambisa kwema diski mumatokisi ndiyo inonyanya kukosha mukushanda kwekutya. Iyo yakakwirira iyo inotenderera inomhanya yemotokari, iyo inowedzera dhidhii iyo inogona kuverenga nekunyora kubva mumotokari mune imwe nguva yakatarwa. Kupisa uye ruzha ndidzo mbiri dzinobhururuka dzenhepfenyuro yepamusoro. Kupisa kunokonzera kushanda kwemagetsi mukati memakombiyuta, kunyanya kana pane uwandu hwemhepo yakashata. Mhere-mhere inogona kukanganisa zvipfeko zvevanhu vari mukati kana makakomba kombiyuta. Yakawanda yekombiyuta inotambaira pakombiyuta inotenderera pa7200 rpm. Imwe yepamusoro yepamhanyi inotyisa inotambaira pa10 000 rpm.
Access Times
Kutsvaga nguva dzinoreva nguva yakareba iyo inotora motokari kuti iise musoro wekutya mundiro yebasa rakakodzera. Iko kune nheyo dzinowanikwa nhatu dzinotsanangurwa pamatokari ose akaoma pamusika:
- Verenga Tsvaka
- Nyora Tsvagai
- Track-to-Track
- Full Stroke
Zvose zvina dzinotaridzwa milliseconds. Verenga kutsvaga kazhinji inowanikwa nguva yakawanda inotora kuendesa musoro kubva pane imwe nzvimbo pamotokari kune imwe kuti uverenge data kubva kuchiteshi. Nyora kutsvaga inenge yakawandisa yakawanda yenguva iyo inotora motokari kuenda kune chimwe chinhu chisina chinhu pane disk uye uchitanga kunyora data. Track-to-track ndiyo inowanikwa yakawanda yenguva iyo motokari inotora kuti iendese musoro wekutya kune imwe nzira yekutengesa pane motokari. Kurwisa kwakakwana inguva yenguva inotora musoro wekutenderera kuti uende kubva kune imwe kunze kune chikamu chemukati che disk kana hurefu hwakazara wekutenderera musoro wekufamba. Kune dzose idzi, nhamba yakaderera inoreva kushanda kwakakwirira.
Chinhu chekupedzisira chinokanganisa kushanda kwebhuku rakaoma ndiro chiyero chebhuku pamotokari. Ikutakura motokari inguwandu ye RAM pamutokari yekuchengetedza kazhinji dhesi inowanikwa kubva kuchiteshi. Sezvo RAM ichikurumidza pakuendesa dhamusi kupfuura kutengesa musoro musoro, inowedzera kasi yemotokari. Iyo inowedzera kubhadhara pamotokari, iyo inowedzera data inogona kuchengetwa muchidziro ichi kuderedza chiyero chekushanda kwepanyama. Mafambiso akawanda nhasi anouya ne 8MB drive buffer. Zvimwe zvinotungamirira zvinotakura zvakadaro zvinouya nechepamusoro 16MB buffer.
