Hnub, cov drives siab yog cov nyiam tshaj tawm sab nraud. Tsis zoo li optical thiab sib nqus disks (CD / DVD thiab nyuaj drives, ntsig txog), flash drives muaj ntau compact thiab resistant rau mechanical puas tsuaj. Thiab vim li cas twb tiav compactness thiab stability? Cia peb pom!
Lub flash drive muaj dab tsi thiab ua li cas
Thawj qhov uas yuav tsum tau nco yog tias tsis muaj qhov txav ntawm txhua yam tsav hauv lub tshuab flash uas tuaj yeem raug kev tsim txom los yog ntog. Qhov no yog tiav los ntawm tus qauv siv - tsis muaj cov ntaub ntawv tiv thaiv, USB flash drive yog lub rooj tsav xwm luam tawm uas tus USB connector yog siv. Cia saib nws cov khoom.
Lub Nroog Cheeb Tsam
Cheebtsam ntawm feem ntau flash drives tau faib ua theem pib thiab ntxiv.
Cov tseem ceeb yog:
- NAND nco chips;
- xws li;
- quartz resonator.
- USB connector
NAND nco
Tus tsav ua haujlwm los ntawm NANDRA-nco: semiconductor chips. Cov teeb meem ntawm lub cim xeeb no yog, thawj zaug, heev compact, thiab secondly - heev capacious: yog thaum xub thawj cov drives tau poob rau hauv cov me me mus rau qhov niaj zaus kho qhov muag disks thaum ntawd, tam sim no lawv txawm tshaj Blu-Ray discs hauv lub peev xwm. Xws li nco, ntawm lwm yam, kuj yog tsis-volatile, uas yog, nws tsis yuav tsum tau lub hwj chim qhov chaw khaws cia cov ntaub ntawv, tsis zoo li RAM chips tsim siv ib tug zoo xws li technology.
Txawm li cas los, NPE-nco tau ib drawback, zoo sib xws nrog lwm hom cia li. Qhov tseeb yog hais tias lub neej ntawm cov chips no tsuas yog siv rau qee cov xov tooj ntawm cov kev hloov rov qab (cov ntaub ntawv nyeem ntawv / sau cov kauj ruam hauv hlwb). Qhov nruab nrab, cov naj npawb ntawm kev nyeem ntawv sau yog 30,000 (nyob ntawm seb lub cim xeeb nti). Nws zoo nkaus li ua tau ntau ntau heev, tab sis qhov tseeb nws yog 5 xyoos siv heev. Txawm li cas los xij, txawm tias txwv tsis pub tshaj tawm, lub tshuab flash tseem tuaj yeem siv, tab sis tsuas yog rau kev nyeem cov ntaub ntawv xwb. Tsis tas li ntawd xwb, vim yog qhov xwm txheej, NAND nco yog qhov yooj yim heev rau hluav taws xob thiab electrostatic tawm, yog li ua kom deb ntawm cov chaw muaj kev phom sij.
Xws li
Ntawm tus xov tooj 2 nyob rau hauv daim duab thaum pib ntawm tsab xov xwm muaj ib tug me me nti - ib tug xws li, ib lub cuab yeej sib txuas ntawm flash nco thiab txuas nrog (PCs, TVs, tsheb xov tooj cua, thiab lwm yam).
Tus maub los (tsis yog hu ua tus microcontroller) yog lub tshuab computer minimalist nrog nws tus kheej processor thiab ib qho txiaj ntsig ntawm RAM siv rau cov ntaub ntawv kev nrhiav thiab kev pab cuam. Nyob rau hauv txoj kev kho kom haum cov firmware los yog BIOS txhais tau tias yog cov software hloov tshiab ntawm cov microcontroller. Raws li kev xyaum qhia, feem ntau tsis ua hauj lwm ntawm cov flash drives yog qhov tsis ua hauj lwm ntawm tus neeg tswj xyuas.
Quartz resonator
Kev tivthaiv no yog ib qho siv lead ua quartz, uas, raws li nyob rau hauv ib qho kev saib xyuas hluav taws xob, ua rau muaj qhov sib txawv ntawm lub cev. Nyob rau hauv flash drives, lub resonator yog siv rau kev sib txuas lus ntawm tus maub los, NAND nco thiab ntxiv yam.
Qhov no yog qhov flash drive kuj yog kev pheej hmoo ntawm kev puas tsuaj, thiab, tsis zoo li cov teeb meem nrog ib tug microcontroller, nws yuav luag tsis yuav daws tau koj tus kheej. Zoo hmoo, nyob rau hauv niaj hnub drives resonators tsis kuj tsis tshua muaj.
USB connector
Hauv feem ntau ntawm cov neeg mob, niaj hnub USB flash drive nruab nrog hom A USB 2.0 connector, uas yog taw qhia kom tau txais thiab xa tawm. Cov drives tshiab siv USB 3.0 Hom A thiab Hom C.
Cheebtsam ntxiv
Ntxiv rau qhov saum toj no-lum lub ntsiab lus ntawm lub twj tso kua hluav taws xob, manufacturers feem ntau muab lawv nrog cov khoom yeem, xws li: tus cim qhia LED, sau kev tiv thaiv kev sau, thiab ib co nta tshwj xeeb rau qee cov qauv.
LED qhov taw qhia
Muaj ntau lub vag drives muaj lub me me, tiam sis ci ntsa iab. Nws yog tsim los siv kev pom qhov kev ua si ntawm qhov flash drive (sau ntawv lossis nyeem cov ntaub ntawv) lossis tsuas yog tus qauv tsim.
Qhov kev ntsuas no feem ntau tsis muaj qhov haujlwm zoo rau lub flash drive nws tus kheej, thiab xav tau, qhov tseeb, tsuas yog rau kev yooj yim ntawm tus neeg siv los yog kev zoo nkauj.
Sau kev tiv thaiv kev hloov
Cov keeb no muaj ntau dua rau SD-phaib, tab sis qee zaus nws muaj nyob rau ntawm USB cia li. Cov tom kawg yog siv rau hauv chaw ua haujlwm xws li cov khoom nqa ntawm ntau yam ntaub ntawv, suav nrog tseem ceeb thiab tsis pub leej twg paub. Yuav tsum tsis txhob muaj qhov xwm txheej tshem tawm ntawm cov ntaub ntawv, cov lag luam ntawm flash drives hauv qee yam qauv siv txoj kev tiv thaiv: thaum uas sib txuas rau lub hwj huam ntawm ib lub tshuab cim xeeb, tiv thaiv hluav taws xob tam sim no kom tsis txhob ncav lub cim xeeb.
Thaum koj sim sau lossis rho tawm cov lus qhia los ntawm tus tsav hauv qhov kev tiv thaiv muaj peev xwm, tus OS yuav tso tawm cov lus qhia no.
Zoo sib xws, kev tiv thaiv yog siv rau hauv lub thiaj li hu USB-tuav: flash drives, uas muaj daim ntawv pov thawj ruaj ntseg tsim nyog rau kev khiav lag luam ntawm qee qhov software.
Lub caij no tseem tuaj yeem ua txhaum, ua rau muaj kev ntxhov siab - cov cuab yeej zoo li yuav ua haujlwm, tabsis nws tsis tuaj yeem siv nws. Peb muaj cov ntaub ntawv ntawm peb qhov chaw uas tuaj yeem pab daws qhov teeb meem no.
Nyeem ntxiv: Yuav ua li cas kom tshem tawm kev tiv thaiv sau ntawv ntawm ib qho flash drive
Cheebtsam cim
Cov no muaj, piv txwv li, lub xub ntiag ntawm cov khoom sib txuas, MicroB lossis Hom-C: flash drives nrog cov neeg uas siv rau kev siv, nrog rau smartphones thiab ntsiav tshuaj.
Saib kuj: Yuav ua li cas coj mus cuag ib tug flash tsav rau lub smartphone ntawm Android los yog iOS
Muaj cov tsav tsheb nrog kev tiv thaiv ntau tshaj plaws ntawm cov ntaub ntawv kaw tseg - lawv muaj ib cov kauj ruam built-in rau hauv ib lo lus zais ruam.
Qhov tseeb tiag, qhov no yog qhov ntau tshaj plaws ntawm qhov saum toj-hais txog kev tiv thaiv kev tiv thaiv.
Qhov zoo ntawm cov drives:
- kev ntseeg tau;
- muaj peev xwm loj;
- compactness;
- tsis kam rau txhua yam kev nyuaj siab.
Tsis zoo ntawm cov drives:
- fragility ntawm lub Cheebtsam;
- kev pab cuam txoj sia tsawg;
- kev ruaj khov rau qhov poob siab thiab cov tso tawm zoo li qub.
Los ua ke - lub flash drive, los ntawm kev taw qhia kev pom, yog qhov nyuaj. Txawm li cas los xij, vim yog lub zog ntawm lub xeev thiab lub zog ntawm lub cheebtsam, ntau dua kev ua haujlwm rau cov neeg ua haujlwm nceb. Ntawm qhov tod tes, cov flash drives, tshwj xeeb tshaj yog cov ntaub ntawv tseem ceeb, yuav tsum muaj kev tiv thaiv los ntawm cov teeb meem ntawm cov cua daj cua dub lossis hluav taws xob.
