Thiab yog nws tsim nyog?

Sij hawm ntawm sab nraud cia li, txhua qhua tuaj noj mov yog sib txawv. Loj qhauj xav tau kom lub hnub hloov nyob rau hauv lub database. Qhov tseeb hais tias loj nyiaj ntawm cov ntaub ntawv tsuas tsis tau muab tso rau hauv lub hauv paus ntawm ntau yam servers thiab ntau yam computers. Thiab mus rau lub heev cov ntaub ntawv ntawm yav dhau los sij hawm yuav tsum tau kho tsis tu ncua, rau Piv txwv li, rau cov kws tshuaj ntsuam los yog ceeb toom.

Tsev neeg siv kom conveniently rov qab xov xwm cov ntsiab lus, txuag cov duab, cov yeeb yaj duab los yog cov suab paj nruag ntaub ntawv. Los ntawm txoj kev, muaj ntau cov tswv ntawm PCs thiab laptops naively ntseeg tau hais tias cov ntaub ntawv thiab thiaj li securely khaws tseg rau hauv hard drive. Txawm li cas los, ob peb cov neeg paub hais tias lub zog tsav yog lossi ua hauj lwm lub neej yog sharply txo thiab cov reserved ntaub ntawv tej zaum yuav tsuas yuav poob. Rau cov hom phiaj, thiab yog nruab nrog computers ntawm cov neeg siv nyob rau hauv-lub khw DVD-ROM tsav, muaj peev xwm ntawm cov ntaubntawv povthawj siv rau kho qhov muag disks.

universal optics

Yog, cov xov xwm nyob rau hauv kho qhov muag discs yog cov uas yooj yim piv txwv. Muaj lwm cia li, CD-, DVD-, HD- thiab Blu-txoj sab ci-disks. Lub ntsiab qauv tshau rau xws tsheb yog siab muaj kev cia siab cov ntaub ntawv cia. Nws yog ib qho nruab nrab ntawm 70-100 xyoo. Txawm li cas los, qhov no daim duab no tsuas yog ua tau nrog ib tug txhim khu kev qha kev tiv thaiv tiv thaiv lub cev disks.

Raws li rau lub ntim, muaj yog twb ntshiab faib mus rau hauv pawg, nyob qhov twg CD- thiab ib tug DVD-disk yog muab 700 MB thiab 4 GB, ntsig txog, thiab xov xwm Blu-txoj sab ci - 25-50 gigabytes. Hlob uniformly los ntawm lub ntim thiab tus nqi ntawm kev sau ntawv ntaus ntawv, ua ke nrog muaj. Tsis txhob hnov qab txog cov ntaub ntawv tus nqi - vim tus kho qhov muag ntaus ntawv yog thov mus rau lub disk-line qauv (laser-ces ib tug), ces sau ntawv mus rau disk peev xwm loj yuav tsum tau ib tug ntau lub sij hawm.

Pom zoo NWS cov tub txawg

Txawm li cas los, kho qhov muag sab nraud cia ntaus lub computer tseem nrov ntawm lub tsev cov neeg siv, thiab yog nyob rau hauv coob nyob rau hauv cov lag luam me me, uas yog ib daim ntawv, los yog muaj ib tug me me database. Cov tub txawg xav kom muab kev xaiv li cas mus rau lub pa DVD-ROM tsav. Qhov tseeb hais tias tus ntaus ntawv yog nyob rau hauv nruab nrab ntawm lub golden ntawm kev "nqi-zoo". Yog, thiab compatibility rau cov neeg yuav tsis muaj teeb meem.

Cov neeg siv yuav tsum xyuam xim rau cov tau overwriting cov ntaub ntawv (Txawm tias nws yuav muaj mus yuav cov tsim nyog tshaj tawm). Nyob rau hauv txhua rooj plaub, lub buyer yuav tau txais ib tug tsim nyog cia lwm ntaus ntawv, uas muaj feem ntau ntawm cov kev tsim nyog zoo. Zoo tsim nyob rau hauv lub kho qhov muag tsav lag luam makers LG, Samsung thiab Asus. Tab sis hauv xov xwm yog zoo dua yuav hom verbatim - no lub tuam txhab tsis yog cov ntaub ntawm puas khoom.

Tsis-volatile nco

Yog, li ib txwm flash thiab SSD-drives kuj yuav ntshai li DDT, tab sis thaum nws los txog rau lub tsev siv, los yog luv luv-term cia ntawm cov ntaub ntawv. Lub fact tias lub peev xwm ntawm ib tug uas tsis yog-volatile nco yog tus nqi uas siab nyob rau hauv lub ratio ntawm "nqi-volume" thiab unreliable. Raws li kev xyaum qhia tau hais tias, cov tib USB flash drive yooj yim ua rau hauv disrepair nyob rau hauv lub li ib txwm zoo li qub hluav taws xob paug, uas accumulates nyob rau hauv tib neeg lub cev. Qhov no yam ntxwv uas niaj hnub sab nraud cia li, yog kom meej meej tsis nyob rau hauv dej ua si rau lub seemingly yooj yooj yim thiab txhim khu kev qha cov khoom.

Tsis xav kom muaj tej illusions tias nyob rau hauv lub xyoo tom ntej qhov teeb meem no nrog cov Nand-nco kev hloov. Lub tagnrho yuav loj hlob nyob rau hauv ncaj qha kev faib ua feem rau tus nqi. Qhov teeb meem nrog zoo li qub tsis tau solved, vim hais tias yuav tsis muaj kev xav tau kev pab mus yuav tus tshiab kiag li lawm. Rau nruab nrab thiab loj ua lag luam, raws li tau zoo raws li factories thiab qhauj tej ntaub ntawv xov xwm yog tsis zoo li yuav pab tau raws li ib tug txhim khu kev qha saib.

unreliable pab kiag li lawm

Kws txawj pom zoo kom tag nrho cov neeg tuaj tshiab uas yog tsis zoo versed nyob rau hauv computer technology, yog cais los ntawm cov ntawv teev cov sab nraud cia li xws li nco daim card thiab flash drive.

Teeb meem abound nyob rau hauv cov drives. Pib los ntawm cov pa tsis ua hauj lwm vim zoo li qub voltage xaus commonplace lub cev puas tsuaj los ntawm xa me nyuam rov los yog kev sib cuag nrog dej nyob rau hauv cov neeg ntawm lub ntaus ntawv. Yog, cov txheej txheem no yog pheej yig, nws yog ib qho yooj yim mus ua hauj lwm thiab muaj ib tug loj ntim. Tab sis nws yooj yim lub hom phiaj - nws yog ib tug luv luv lub sij hawm cia ntawm cov ntaub ntawv, uas yog tsim nyog nyob rau hauv cov ntaub ntawv ntawm kev thauj mus los. Thaum qhov zoo ntawm cov khoom thiab qhov kawg.

Yuav ua li cas xaiv ib tug flash tsav?

Cov yam ntxwv ntawm lwm cia li raws li nyob rau hauv Flash tsuas yog ib - yog cov ntaub ntawv sau ntawv ceev. Tsis txhob xav tau tus neeg muas zaub mus saib cov tsos los yog yooj yim, cov xim los yog cov khoom, ces nws yog tag nrho hais txog ib tug kos xws li, uas yuav muaj mus ua hauj lwm sai sai, tsis hais txog ntawm lub cia ntim thiab connectivity interface.

Yog hais tias peb tham txog nco phaib, cov kev xaiv no yog heev yooj yim - koj yuav tsum ua kom pom tseeb rau hauv lub chav kawm ntawv ntawm lub ntaus ntawv. Lub sab nws yog, lub qeeb qeeb hauv cov ntaub ntawv yog muab sau tseg rau cov cab kuj. Qhov tseeb tiag mas, zoo dua yuav muab nyiam mus rau lub qib 10 thiab labeling Ultra. Yog hais tias peb tham txog hom, uas yog cov pov thawj nyob rau hauv kev ua lag luam ntawm lub tuam txhab Transcend, Pretec, SanDisk thiab Team.

Tab sis nrog ib tug USB-drives yog ntau npaum li cas complicated. Ntawm no feem ntau ntawm cov manufacturers cov uas ntsiag to txog cov sau ceev. Qhov no hom tsis yog ib tug priori tsim nyog los muab txawm xim. Tag nrho li nrog dlej ua hauj lwm ceev ncaj qha rau ntawm lub pob qhia rau cov ntaubntawv povthawj ceev nyob rau hauv USB 2.0 hom. Sab nraud cia li Kingston, Transcend Pretec, thiab nyob ntawm no, ntawm chav kawm, yog cov thawj coj. Sau ceev ntawm xws li kom meej meej tshaj 10 megabytes ib ob. Thiab nws yog tiag tiag uas tsim nyog daim duab.

Nthuav kev tawm

Nws yuav tsum tau muab sau tseg tias niaj hnub sab nraud cia li, SSD kim disks, nrog rau cov kev kub ceev kev ua tau zoo, thiab muaj dlej muaj kev cia siab nyob rau hauv tej kev txiav txim.

Yog, raws li koj nyuaj tsav SSD-tsav tom qab qhov kev puas tsuaj yog tsis tau mus ua hauj lwm. Tab sis nws yuav tig mus rau hauv ib tug lossis loj stick, uas yuav tsum tau kev raws li ib tug yav tas los ntaub ntawv kaw tseg. Nws yog qhov no feature thiab attracts tej zaum cov neeg muas zaub mus rau ib qho nkaus tshiab technology nyob rau hauv lub computer ua lag luam, vim hais tias cov cia cia siab rau yog ib feem rau feem ntau.

Npaj ua kev daws teeb meem nyob rau hauv lub computer ua lag luam

Basic yam ntxwv ntawm sab nraud cia li thaum nws los txog rau SSD-drives, qhov tsawg kawg nkaus tus nqi ib chav tsev ntawm muab cov ntaub ntawv. Hais tias yog, tus neeg siv yuav tsum txiav txim seb cov khoom rau lub lag luam, tus nqi ntawm uas raws li ib tug ntim. Yuav kom nrhiav tau tawm nws yog yooj yim zoo nkauj - koj yuav tsum phua lub nqi rau lub SSD-tsav loj. Yog li ntawd, buyer paub ntau npaum li cas yog 1 gigabyte ntawm cov ntaub ntawv khaws tseg rau hauv xov xwm. Nyob rau nruab nrab, cov nqi ntawm 1 GB yuav tsum tsis muaj ntau tshaj li 10-15 rubles.

Nws yog ib zajlus kom xav hais tias cov ntaus ntawv yog ib qho kev zoo xwb los kis tau cov ntaub ntawv los ntawm ib tug loj ntim (tshaj 640 gigabytes). Yes, nws yog. Nrog kev xav txog tej hom, cov kev xaiv yog loj txaus. Qhov tseeb yog tias tag nrho cov manufacturers siv zog los yeej muaj cov haum ntawm tus neeg muas zaub thiab muab cov kev ua lag luam tiag tiag tsim nyog cov khoom. Zoo tsim hom: Transcend, Toshiba, Kingston thiab Samsung. Cov buyer yuav tsum xyuam xim rau cov ntaub ntawv tus nqi, txhua chaw tsim tshuaj paus sib txawv.

Dhia los ntawm lub xyoo lawm

Nyob deb ntawm cov txhim khu kev qha thiab cuab yeej zoo heev yog hais tias yuav tus tsav, uas tau sau cov ntaub ntawv ntawm kev kub ceev rau ib tug tshwj xeeb daim kab xev cartridge. Txij li thaum lub yooj yim yam ntxwv ntawm lwm cia li - yog muaj kev cia siab thiab ambiance rau, nws yuav nrhiav tsis tau ntau tshaj li ib zaug xwb ntsuas nyob rau hauv lub ntiaj teb no, muaj zoo xws li cov yam ntxwv.
