Chii chinonzi SSD? A mberi itsva kukura dzakakwirira ruzivo

Technical mberi yava kukura. Kune zvitsva mano aivabatsira yekudyidzana upenyu murume ano. Izvi ndezvechokwadi kunyanya siyana kombiyuta peripherals. Izvi yepamusorosoro namano kuti yakabuda ichangobva vari chakasimba-mamiriro Zvifambiso. Pamutemo, idzva nhau, zvimwe sevatsigiri SSD, shandisa zviviri zvamarudzi ndangariro: kubva NAND uye RAM. Zvifambiso nendangariro rechipiri mhando hadziwanzowaniki uye zvinoshandiswa mafomu yaida kutsanya zvakaoma nemotokari unongotaura. NAND-Zvifambiso zviri zvikuru zvakafanana. Izvi mhando ndangariro yakashandiswa Mobile mano uye tsika hrs, saka nyaya ino ichakurukurwa chinhu NAND-Zvifambiso.

Chokwadi iri SSD uye sei akasiyana kwakajairika dzakaoma Zvifambiso, wamusingazivi zvose. Zvichakadai, kusiyana chikuru pakati pavo - kuverenga uye kunyora nokukurumidza. SSD Izvi zvikuru mberi zvimwe zvose nhau. By sechivako yakasimba wehurumende nemotokari zvakare vangasimudzira rakasiyana zvakaoma tikachirega. Kana wechipiri zvikamu ichifamba, kuti SSD ane monolithic chivako kuti anopa anenge akanyarara kushanda Laptop kana piritsi. Chaizvoizvo chii yakasimba-hurumende Zvifambiso havana kuverenga musoro rinopa pasi simba zvinodyiwa uye nokukurumidza kuverenga yakakwirira, uyewo diki kukura uye yakakwirira mukurumari yacho mudziyo. Chimwe chakanakira SSD mudziyo huru inowirirana zvose panhu interfaces.

Mumwe rokushandisa, tsvaka izvo SSD, sokuti mudziyo iri rinenge hapana zvaunokanganisa. Zvisinei, hazvisi. The chikuru zvakaipira SSD anonzi mashoma "pasherufu upenyu." Uyewo isipi-nemotokari, hwakasimba hurumende nemotokari ine finite nhamba nyora zvinogara. Zvikurukuru kuremara iyi zvakasimba vainzwa nokuda kudhura ari mudziyo, iyo zvinoenderana inzwi rayo.

Vakawanda vanofarira kwete chete izvo SSD, asiwo chii ari mudziyo zvakasiyana senguva rutanda. SSD anogona kunzi ane "mukoma guru" nokupenya. Ivo anosiyana, pakutanga kwezvose, chokwadi chokuti USB nemotokari ndiyo Chip imwe chete isipi-ndangariro, uye SSD anoverengeka, uye ruzivo pamusoro pavo zvakanyorwa rave. Kazhinji, kuti vawedzere chokupika mudziyo pamusoro wayo pcb akatasva kuroora nokupenya ndangariro chip. Controllers mu yakasimba-hurumende okuchengetera zvakare basa kudarika USB. Izvi zvinopa SSD yakareba inoshanda.

Zvirokwazvo vanhu vane hanya mubvunzo uyu uye kuti izwi SSD basa. Kufanana USB-nemotokari, rakasimba mamiriro nemotokari, ari pasherefu upenyu haisi kuyerwa nemakore, uye overwrite zvinogara. nemotokari yavo anomira kubva zviuru mazana mashanu hafu yemiriyoni. Saizvozvowo, paunonyanya kushandisa mudziyo, asi nokukurumidza ichava maturo. Kunowedzera uchishandisa upenyu uye anokosha controllers okuchengetera nako ndangariro masero inoshandiswa zvikuru kana zvishoma zvakaenzana. Kana nguva, vaitungamirira SSD vagadziri hunovimbisa makore matatu dambudziko isina kushanda mishonga kwayo. Kana pakuguma SSD "pasherefu upenyu", izvi hazvirevi kuti mudziyo raputsika. Hakuzovi kukwanisa kunyora mashoko matsva, asi mashoko kuchengetwerwa zvichangoramba kuwanikwa.

Kwakaita SSD akasiyana kunyanya kukura. Kazhinji ndivo kana 1,8 padiki kana 2.5 padiki, asi dzimwe nguva pane vasiri mureza 3.5-padiki chikwata. Dzinowanzotanga zvakabatana Via eSATA connector. Kana iwe kubatanidza SSD Via USB-inowanikwa zvakanakisisa kushandisa USB 3.0. Zvino, pamwe hwakasimba ehurumende Zvifambiso, ari SSD, pane kuwedzera makadhi, izvo zvinoshandiswa Laptops uye servers. Uyezve, vagadziri vakawanda pave kuti "chemasanganiswa" SSD uye kwakajairika zvakaoma dhisiki imwe mhando. Kwakadaro vakaberekwa mano vane kumhanya uye vane gwanza yokuchengetera mashoko.

Vakawanda vanoshandisa vasati vadzidza kuti kuvimba hwakasimba-mamiriro Zvifambiso. Wana mhinduro dzemibvunzo pamusoro izvo SSD, wose achakwanisa kusarudza inoda chitsva mhando kuchengetwa mudziyo, kana unogona kuwana zvakanaka yekare zvakaoma tikachirega.
