Ndeupi nani: SSD kana HDD? Musiyano uri pakati SSD uye HDD?

Kana kutenga PC mutsva kana ndiwedzere hwakare dhisiki imwe kombiyuta hazvo anomutsa mubvunzo wokuti: "Zviri nani - the SSD kana HDD» makore mashanu apfuura, mubvunzo uyu harimuki?. Alternatives kune kwakajairika zvakaoma dhisiki haana (zita rake rechipiri - "zvakaoma ngarurege" kana kungoti "sikuruu"). Saka, ndiko yakadaro mudziyo kuti kuchengeta mashoko anoshandiswa kwose kwose. Asi zvino zvinhu zvachinja zvikuru. Kuwedzera, vanoishandisa tisasiya yakasimba-mamiriro Zvifambiso, iyo, kunyange vari anodhura, asi kuita kwavo yepamusoro zvikuru.

nyaya

Usati uzive zvinhu musiyano SSD uye HDD, isu kutora muchidimbu nhoroondo muchidimbu uye kuongorora mashoko okuchengetera michina kuti rinoshandiswa ose mhando mudziyo.

Wokutanga ngarurege zvizere pamusoro zvakaoma dhisiki (mukuru zita) chakaitwa IBM Corporation muna 1973 gore. Zvadaro Inzwi rayo riri 60 MB (2 MB kubva pamahwendefa 30). Mumakore 40-shamisa makore, zvakadai mano kunge wakashanduka-shanduka, uye maitiro avo nani nokuda kakawanda - zvose kugona uye unongotaura. Asi ruzivo havana kushanduka. Hwaro chero HDD (kubva Chirungu shoko «zvakaoma» - zvakaoma, «dhisiki» - drive «ngarurege» - iyi kana nemotokari) nhema ndiro zvemapuranga ane ferromagnetic rukoko. With musoro nayo anosika imwe dzidziso ( "kuchamhembe" uye "rwezasi" Matanda kuti anoenderana musoro "0" uye "1"). SSDs vakatanga kuudzwa nezvechokwadi muna 1978. Asi kwakapararira Kushandiswa yavo yakati yapfuura - the hrs kutanga navo panzvimbo huru okuchengetera mudziyo, akaonekwa 2009. Solid-mamiriro okuchengetera mano kunobva semiconductor zvokuvakisa, izvo anoumbwa "nemasero". Zvakadaro "sero" anogona kunyorwa tsika mbiri chete "0" (hapana chiratidzo) uye "1" (zvinogona chipo). Nokudaro musiyano HDD uye SSD. Musiyano kubva HDD ndizvo chii rinoshandiswa pagadzirwe vamwe zvinhu (nesilicon Anti-ferromagnet) uye akaita musimboti mashoko okuchengetera (ICs pamusoro ndiro). Nezvazvo kuyeuka pakusarudza mudziyo mutsva mukirasi yacho.

The klassiske Version

Kuti tipindure mubvunzo, chii nani - SSD uye HDD, tarisa nomumwe okuchengetera mudziyo nomumwe ruzivo. Kutanga wechipiri pavo. Ndiwo chaiwo musiyano pakati kurongwa dhisiki hurongwa. The chikuru zvechadenga zvakaoma ngarurege sezvinotevera:

• Capacity - uwandu mashoko mudura grade nhamba hurongwa. Panguva iyoyo paakati ino uchishandisa ino ichava yakasiyana, nekuti pano dzemaitirwe kwatova binary ino. Pari kutengeswa okuchengetera inokwana 250 GB kusvika 8 TB.
• kubatanidza inowanikwa zvinogona Ide, USB uye SATA. Wokutanga wavo mutsika uye mumuviri usashanda uye ari kungoshandisa pamusoro PC kuti asunungurwa 5 apfuura uye adarika. Wechipiri mukuru kuti inotakurika date chekuchengeta. Uye wechitatu, chikuru - zvino kushandiswa kunenge kwose. Shanduro yake yokupedzisira ine indekisi kuti "3". All namano kuti anogona kushanda shanduro iyi inowanikwa anogona kutapurira mashoko ari kusvika 6 GB / s. Uyewo, SATA chinokosha shanduro indekisi «M», iyo inoshandiswa chete Laptops uye netbooks.
• The date chinja unodiwa. Sezvambotaurwa, izvozvo zvinoenderana norudzi inowanikwa. The yepamusoro zviri, nani.
• chitete kutenderera maitikiro. Zvino Kutengeswa pane mienzaniso 5400 uye 7200. paminiti. Chii mufananidzo uyu yakakwirira, dzakanga chokupika.

Ndivo chikuru zvechadenga zvakaoma disk. Kupindura mubvunzo, chii nani - SSD uye HDD, unofanira kufunga parameters zvokufonongonwa-ehurumende Zvifambiso. Zvahuchaita kuitwe.

Utsanzi

Mune imwe nzira, sezvo anoziva, kuti SSD haangavi zita. mano izvi akaenda pasero makore mashanu apfuura. Pakarepo constraints vari kudhura dzavo uye guru kukura. Asi zvino zvinhu zviri zvishoma nezvishoma kuchinja. Kuwedzera, vanogona kuwanikwa desktops uye Laptops. Main zvatariswa vane zvinotevera:

• Capacity - zvakafanana kuti zvakaoma tikachirega. Zvino iripo yokutevedzera kubva 32 GB 1 TB.
• Manufacturing muitiro unogona kubva 19 nm 26 nm. Vashoma, chokupika nani, asi akazoita nhamba masero overwrite zvinogara.
• Connection inowanikwa. Vose zvakafanana avo kare kupiwa nokuda HDD, kunze Ide, iro harishandiswi nokuda SSD.
• Kuwanda nyora zvinogara. Zvingava kubvira 1000 kusvika 5000 zvinogara. The yepamusoro mutengo, Kureba SSD.

Inobva kumusoro, unogona kupa nyore mhinduro chii akasiyana SSD HDD uye kuti ndiye nani.

enzanisa Zvifambiso

Achifananidza chokupika nerimwe Zvifambiso zvinogona kuzivikanwa kuti hwakasimba hurumende kuva yepamusoro date unodiwa. Izvi kunosimbiswa nemashoko mabikirwo pachayo. Microchips mune zano iri nani kupfuura rinobva mahwendefa. On zvakanakira kwakadai mugumo mano. Kana iwe enzanisa mutengo uye kukura nemotokari, zvinoitika kuti pane imwe mutengo 40-50 USD unogona kutenga 32 GB SSD kana HDD 160-250 GB. Saka, kusarudza vanoshandisa vakawanda. Panguva mutengo zvingava nani pane vhoriyamu kupfuura kuita. Uyewo, vaifanira vanokwanisa vari HDD yakawanda 8 nguva (1 GB kusvika 8 GB).

Chii uye kupi nani?

Zvino ngatitarise kubata izvo zviri nani - the SSD kana HDD - neimwe nyaya. Nokuti Multimedia dzemapurisa uye hofisi hrs akakwana kuti dzakaoma Zvifambiso inokwana 160-320 GB. Uye mutengo yakaderera, uye kukura ichi chichava zvinokwana matambudziko kuti anogadziriswa. Mamiriro ezvinhu akafanana ne netbooks uye kupinda-pamwero Laptops. Asi mukuru-waivako Mobile makombiyuta zvichava kurwa nani SSD kukura 128-256 GB. Gaming bv, Graphics workstations uye servers zvinofanira inodiwa kuti yakanyatsoiswa pamwe 2 Zvifambiso. Rimwe hurongwa uye zvirongwa - SSD ichi. Uye chechipiri - the nemotokari zvakaoma kuti achengetere User Data. Izvi zvichaita kuwana uye kumhanya, uye zvaida vhoriyamu kuti mashoko okuchengetera.

zvabuda

Sechikamu ino zvakaitwa nokuenzanisa yakazara SSD uye HDD, zvichiratidza maitiro avo chikuru, kurumbidza nokuda kwokushandisa kwavo, vachitevera izvo unogona nyore osimudza mashoko okuchengetera mudziyo kuti zvakakodzera zvaunoda zvakanaka.
