Tsanangudzo yeHat Drive Inoda Nguva
Nguva yekutsvaga ndiyo nguva inotora chikamu chakati chema mechanics ye hardware kuti uwane chimwe chikamu chemashoko pane imwe chigadziro chekuchengetedza. Nhamba iyi inowanzonzi milliseconds (ms), apo kukosha kwechidiki kunoratidza nguva yekutsvaga nokukurumidza.
Nguva ipi inotsvaga haisi iyo nguva yakawanda yenguva inotora kunyora faira kune imwe dhirairi rakaoma, download data kubva paIndaneti, kupisa chimwe chinhu ku diski, nezvimwe. Kunyange nguva yekutsvaga inobatanidzwa mune nguva yakazara inotora kuti upedze mabasa akadai, zvinenge zvisingabatsiri kana zvichienzaniswa nezvimwe zvinhu.
Tsvaga nguva inowanzodanwa kusvika nguva , asi chaizvoizvo nguva yekuwana yakareba kwenguva yakareba kupfuura nguva yekutsvaga nokuti kune nguva duku ye latency pakati pekuwana data uye zvino kuitora.
Chii Chinosarudza Kutsvaka Nguva?
Nguva yekutsvaga dhirairi rakaoma ndiyo nguva inotora kuti hurukuro yemusoro wegoroidhi (inoshandiswa kuverenga / kunyora data) kuti iite ruoko rwayo rekugadzirisa (uko misoro inosungirirwa) yakamira panzvimbo yakarurama panzira (apo iyo data inonyatsochengetwa) kuitira kuverenga / kunyora data kune imwe nzvimbo ye disk.
Sezvo kuendesa ruoko rwekugadzirisa ibasa ndiro basa remuviri rinotora nguva yekupedzisa, nguva yekutsva inogona kunge yava pedyo nguva iyo kana nzvimbo yepamusoro inenge iine nzira yakarurama, kana kuti yakareba kwenguva yakareba kana musoro uchienda kunzvimbo yakasiyana.
Nokudaro, nguva yekutsvaga dhiyabhorosi iri kuenzaniswa nenguva yakatsvaga yekutsvaga sezvo haisi yega yega dhirairi ichagara iine hurukuro yemusoro panzvimbo imwe chete. Nenguva yekutsvaga yakawanda yekutsvaga motokari inowanzorongwa nekufungidzira kuti zvinotora nguva yakareba sei kutarisa dhenda pamusoro peiiii chetatu emitambarakede.
Zano: Ona peji 9 yemu PDF iyi kubva pawebsite yeYunivhesiti yeWisconsin yehuwandu hwemasvomhu nezvekushandisa nguva yakawanda yekutsvaga nguva.
Kunyange zvazvo muvhareji kutsvaga nguva ndiyo nzira yakawanda kwazvo yekuyera kukosha uku, inogona kuitwa nedzimwe nzira mbiri zvakare: kutarisa-ku-track uye kugadzirisa zvizere . Track-to-track ndiyo yakawanda nguva inotora kutsvaga dheari pakati pematakiti maviri ari pedyo, asi shamhu yakazara ndiyo nguva inotora kutsvaga kuburikidza nehurefu hwose hwe disk, kubva mukati memukati kuenda kune imwe kunze.
Zvimwe zvipfeko zvekuchengetedza zvigadzirwa zvine madhiyabhorosi akaoma zvisinganzwisisiki muhutano kuitira kuti pane zvishoma maitiro, zvichizobvumira bhidhiyo kuti ave nechepfupi pamakwikwi kuenderera mberi nematakiti. Izvi zvinonzi shoro shokking .
Aya mazwi ekutsvaga motokari angave asingazivi uye anokanganisa kutevera, asi iwe wose unoda chaizvo kuziva kuti nguva yekutsvaga dhiyabhorosi yakawanda ndiyo nguva inotora motokari yekuwana deta iri kutsvaga, saka kukosha inomirira nguva yekutsvaga nokukurumidza kupfuura imwe huru.
Tsvaka Nguva Mienzaniso yeChina Hardware
Vavhareji vanotsvaga nguva yekufambisa zvinotyisa zviri kuwedzera zvishoma nezvishoma kupfuura nguva, uye yekutanga (IBM 305) ine nguva yekutsvaga inenge 600 ms. Mumwe mushure memakumi emakore akazotevera akaona nguva yakawanda yeHDD yekutsvaga nguva yekuve yakapoteredza 25 ms. Mazuva ano zvinotyisa zvinogona kunge zvichitsvaga nguva inenge yakapoteredza 9 ms, zvigadzirwa zvemasasa 12 ms, uye masereji ekupedzisira ane makore anosvika 4 masikati munguva yekutsvaga.
Dhiyabhorosi dzakaoma zvinotyisa (SSDs) hadzina mafambiro anofambisa sezvinoita zvinotenderera zvinotenderera, saka nguva dzavo dzinotsvaga dzinoyera zvishoma, uye dzakawanda SSD dzine nguva yekutsvaga pakati pe 0.08 ne 0.16 ms.
Imwe hardware, kufanana ne- optical dis drive uye floppy disk drive , iine musoro mukuru kune dhirairi rakaoma uye saka inonoka kutsvaka nguva. Semuenzaniso, maDVD uye maCD ane nguva yekutsvaga yakawanda pakati pe 65 ms na 75 ms, iyo inononoka zvikuru kudarika iyo inotyisa.
Inotsvaka Nguva Chaizvo Chaizvo Chaicho Chinokosha Here?
Zvakakosha kuziva kuti nepo nguva yekutsvaga ichiita basa rinokosha pakusarudza kufara kwekombiyuta kana chimwe chigadzirwa, kune zvimwe zvikamu zvinoshanda mumagetsi zvakafanana zvakakosha.
Saka kana uri kutarisa kuti uwane dambudziko rekutsvaga rekutsvaga kombiyuta yako, kana kuti kuenzanisa zvinhu zvakasiyana-siyana kuti uone kuti ndiani arikukurumidza, yeuka kufunga zvimwe zvinhu zvakadai se system system , CPU , file system , uye software inoshanda the device.
Semuenzaniso, nguva yose inotora kuita chimwe chinhu chakadai sokukanda vidiyo kubva paIndaneti haina chakanaka zvachose kuita ne nguva yekutsvaga yedhijidhi. Kunyange zvazvo chiri chokwadi kuti nguva yekuchengetedza faira kune disk inotenderera pane imwe nguva panguva yekutsvaga, ichitaura kuti iyo dhirairi yakaoma haina kushanda pakarepo, mune imwe nguva yakafanana neizvi pakunyorera mafaira, iyo yose inokurumidza inokurudzirwa nebandaneti bandwidth .
Izwi rimwechete rinoshanda kune zvimwe zvinhu zvauri kuita sekushandura mafaira , kubvarura maDVD kune dhirairi rakaoma, uye mabasa akafanana.
Unogona Kuvandudza DHD & # 39; s Kutsvaka Nguva?
Kunyangwe iwe usingakwanisi kuita chero chinhu chipi nechipi kuti chikurumidze zvinhu zvenyama yedhirai rakaoma kuitira kuti uwedzere nguva yaunotsvaka, pane zvinhu zvaunogona kuita kuti uvandudze kushanda kwese. Izvi ndezvokuti nguva yekutsvaga motokari haisi iyo chete inokonzera kushanda.
Imwe muenzaniso ndeyokuderedza kupatsanurwa nekushandisa sarudzo yekudzivirira pasina . Kana zvidimbu zvefaira zvakapararira zvose pamusoro pebhuku rakaoma muzvikamu zvakasiyana, zvichazotora nguva yakawedzerwa kuti dhirairi rakaoma kuunganidza nekugadzirisa ivo muchikamu chakasimba. Kuzvidzivirira kwekutya kunogona kusimbisa mafaira aya akaparadzana kuvandudza nguva yekuwana.
Usati wazvidzivirira, iwe ungatotanga kufunga kubvisa mafaira asina kushandiswa sewe browser caches, kubvisa Recycle Bin, kana kutsigira data iyo inoshandisa system isingashandisi kushandiswa, zvichida nedhiyabhorosi yekuchengetedza zvishandiso kana basa rekuchengetedza mutsamba . Nenzira iyo dhirairi rakaoma haifaniri kusvitsa zvose izvi dhidha nguva imwe neimwe inoda kuverenga kana kunyora chimwe chinhu kune diski.
