Flash drives, lossis flash memory devices, yog siv niaj hnub no rau PCs thiab laptops, nrog rau cov koob yees duab digital, ntsiav tshuaj thiab smartphones. Feem ntau ntawm cov xov xwm no tuaj yeem txuas rau hauv USB chaw nres nkoj, tab sis qee hom yuav tsum tau muab tso rau hauv lub siab tawv tsav lossis daim npav nyeem ntawv.
Dab tsi yog flash drives? Muaj ob hom kev tsav tsheb no. Lawv siv thev naus laus zis zoo sib xws tab sis txawv ntawm lub cev thiab sib cuam tshuam.
Secure Digital (SD cards)
Nov yog hom ntawv tsis hloov pauv tsis hloov pauv uas tsim los ntawm SD Card Association (SDA) siv rau hauv cov khoom siv nqa tau. Tus qauv tau tshaj tawm thaum Lub Yim Hli 1999 los ntawm kev sib koom tes ntawm SanDisk, Panasonic (Matsushita Electric) thiab Toshiba thiab txij li ntawd los ua tus qauv kev lag luam. Dab tsi yog qhov loj ntawm flash drives ntawm hom no?
Lub Ib Hlis 2000, cov tuam txhab kuj tau tsim lub koom haum SD (SDA), lub koom haum tsis muaj txiaj ntsig los txhawb thiab tsim cov qauv rau flash drive. Cov hom miniSD tau tshaj tawm thaum Lub Peb Hlis 2003 los ntawm SanDisk Corporation, uas tau tshaj tawm thiab ua qauv qhia qhov nokev tsim kho tshiab. Nws tau txais yuav los ua ib daim ntawv me me ntxiv rau SD daim npav tus qauv. Txawm hais tias cov flash drives tshiab no tau tsim tshwj xeeb rau cov xov tooj ntawm tes, lawv tau pib muag nrog lub adapter uas ua rau lawv sib xws nrog cov qauv SD nco daim npav qhov. Txij li xyoo 2008, qhov kawg tau txiav tawm.
Miniature Secure Digital microSD nco phaib yog Ameslikas hu ua T-Flash lossis TF, uas yog lub npe luv ntawm TransFlash. Lawv ua haujlwm zoo ib yam rau miniSD thiab tuaj yeem ua haujlwm hauv txhua lub cuab yeej nqa tau. SanDisk tau tsim qhov sib txawv no thaum kev sib koom ua ke nrog cov neeg sawv cev ntawm Motorola tau xaus lus tias daim npav nco tam sim no loj dhau rau cov xov tooj ntawm tes. Lub flash drive yog Ameslikas hu ua T-Flash, tab sis lub npe tau hloov mus rau TransFlash tsis ntev ua ntej cov khoom tsim tawm.
Hauv xyoo 2005, SDA tshaj tawm daim ntawv me me microSD nrog rau siab bandwidth Secure Digital Formatting (SDHC) tshaj (2GB). Cov cuab yeej cia no muaj qhov tsawg kawg nkaus nyeem thiab sau nrawm ntawm 17.6 Mbps. SanDisk thawj coj tau hais kom SDA tswj hwm tus qauv microSD. Qhov kawg specification rau cov flash drives tau sau npe rau lub Xya hli ntuj 13, 2005. phaib microSD thaum xub thawj muaj nyob rau hauv 32MB, 64MB, thiab 128MB.
Motorola E398 yog thawj lub xov tooj ntawm tes uas tuaj yeem txuas daim npav TransFlash (tom qab microSD). Ob peb xyoos tom qab, lawv cov neeg sib tw tau pib siv cov flash drives tag nrhokhoom siv.
Dab tsi yog flash drive rau cov xov tooj niaj hnub no? Tam sim no, smartphones siv micro nco phaib, uas feem ntau yog 32 lossis 64 GB. Cov khoom siv me me tau maj mam raug txiav tawm, thiab cov cuab yeej muaj peev xwm ntau dua tam sim no tsis tau txais kev txhawb nqa los ntawm txhua tus qauv xov tooj.
Lub ntsiab lus ntawm cov xov xwm no yog dab tsi?
Daim npav nco tau siv ntau yam khoom siv hluav taws xob thiab tau dhau los ua qhov dav dav ntawm kev khaws cia ob peb gigabytes ntawm cov ntaub ntawv me me. Dab tsi yog flash drives ntawm hom no niaj hnub no? Cov khoom siv uas tus neeg siv yuav nquag tshem tawm thiab hloov flash drives (cov koob yees duab digital, camcorders thiab game consoles) nyiam siv hom mini. Cov khoom siv uas qhov me me yog qhov tseem ceeb (xws li lub xov tooj ntawm tes) nyiam siv daim npav microSD.
Qhov ntau yam ntawm flash drives no tau pab txhawb kev lag luam smartphone, muab cov tuam txhab thiab cov neeg siv khoom zoo sib xws kom yooj yim dua thiab muaj kev ywj pheej. Vim lawv qhov loj me me, daim npav microSD tau siv ntau yam khoom siv nqa tau. Qhov tseeb versions ntawm cov kev khiav hauj lwm loj, suav nrog Windows Mobile thiab Android Marshmallow, tso cai rau cov apps khiav los ntawm microSD phaib, nqa cov haujlwm ntxiv rau cov qauv tshiab.
Txawm li cas los xij, SD phaib tsis yog qhov kev daws teeb meem zoo tshaj plaws rau cov khoom siv uas tsuas yog xav tau me me ntawm lub cim xeeb tsis hloov pauv (piv txwv li, chaw nres tsheb presetshauv xov tooj cua me). Lawv kuj tsis yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau muaj peev xwm cia siab dua lossis nrawm dua. Cov kev txwv no tuaj yeem hais ntxiv los ntawm kev hloov kho lub cim xeeb thev naus laus zis. Daim npav microSD loj tshaj plaws hauv ntiaj teb niaj hnub no muaj peev xwm ntawm 256 GB. Yog li ntawd, nws yog ib qho nyuaj rau kwv yees txawm nyob ze yav tom ntej dab tsi flash drives thiab hom twg yuav tshwm sim sai sai no.
Ntau lub khoos phis tawj ntawm tus kheej ntawm txhua hom, suav nrog cov ntsiav tshuaj thiab smartphones, siv SD phaib los ntawm cov qhov sib xyaw ua ke lossis los ntawm cov khoom siv hluav taws xob siv hluav taws xob. Cov yav tas muaj nyob rau hauv PC Cards, ExpressBus, USB, FireWire, thiab ib tug parallel tshuab luam ntawv chaw nres nkoj. Active adapters tseem tso cai rau SD phaib siv rau hauv cov khoom tsim los rau lwm hom ntawv xws li CompactFlash.
USB sticks

Nyob rau yav tom ntej, flash drives txog li 2 TB tau kwv yees tias yuav kis tau nrog kev txhim kho tas li ntawm lawv qhov loj thiab tus nqi. Ib txhia ntawm nocov cuab yeej muaj peev xwm txog li 100,000 sau thiab tshem tawm cov voj voog, nyob ntawm seb lub cim xeeb nti siv, thiab tuaj yeem nyob nruab nrab ntawm 10 thiab 100 xyoo nyob rau hauv ib txwm muaj xwm txheej.
USB drives feem ntau yog siv rau tib lub hom phiaj uas floppy disks lossis CDs tau siv ib zaug rau, piv txwv li khaws cia, cov ntaub ntawv thaub qab, thiab hloov cov ntaub ntawv hauv computer. Txawm li cas los xij, lawv me dua, khiav nrawm dua, muaj ntau txhiab zaus ntau lub zog, thiab ruaj khov thiab txhim khu kev qha vim lawv tsis muaj qhov txav mus los. Tsis tas li ntawd, lawv tiv thaiv kev cuam tshuam ntawm electromagnetic cuam tshuam (tsis zoo li cov disks) thiab tsis cuam tshuam los ntawm khawb qhov chaw (tsis zoo li CDs). Txog xyoo 2005, feem ntau lub desktop thiab laptop computers tuaj nrog lub qhov chaw floppy disk ntxiv rau USB ports, tab sis qhov kev ua haujlwm no tsis muaj nyob rau niaj hnub no.
Device compatibility
USB flash drives siv cov txheej txheem khaws cia ib txwm muaj kev txhawb nqa los ntawm cov haujlwm niaj hnub xws li Windows, Linux, MacOS thiab lwm yam Unix-zoo li tshuab, nrog rau ntau lub BIOS khau raj ROMs. USB 2.0 muaj peev xwm drives tuaj yeem khaws cov ntaub ntawv ntau dua thiab hloov nws sai dua li cov khoom siv kho qhov muag loj dua (xws li CD-RW lossis DVD-RW) thiab tuaj yeem nyeem tau los ntawm ntau lub tshuab suav nrog Xbox Ib, PlayStation 4, DVD-players. Tsis tas li ntawd, xws li flash drive tuaj yeem nyeem tau los ntawm niaj hnub smartphones thiab ntsiav tshuaj, txawm hais tias SD nco daim npav zoo dua rau qhov no.cov hom phiaj.
qauv ntawm lub flash drive
Ib lub flash drive muaj lub rooj tsav xwm me me uas nqa lub voj voog thiab ib lub USB txuas uas yog rwb thaiv tsev thiab tiv thaiv los ntawm yas, hlau, lossis roj hmab casing. Qhov no tso cai rau tus neeg nqa khoom nqa mus rau hauv lub hnab tshos lossis ntawm cov saw hlau. USB connector tuaj yeem tiv thaiv los ntawm lub kaus mom tshem tau lossis thim rov qab rau hauv lub tsev tsav. Nyob rau hauv cov ntaub ntawv no, nws yog tsis raug rau kev puas tsuaj nyob rau hauv ib tug unprotective xeev. Dab tsi yog flash drives los ntawm hom kev sib txuas? Feem ntau cov tsav tsheb siv tus qauv Hom A USB txuas mus rau qhov chaw nres nkoj ntawm tus kheej lub khoos phis tawj, tab sis kuj tseem muaj cov tsav tsheb rau lwm qhov cuam tshuam. Tag nrho cov flash drives yog powered los ntawm lub computer ntawm ib tug USB kev twb kev txuas. Qee cov khoom siv ua ke ua haujlwm ntawm cov khoom siv xov xwm portable nrog USB flash drive. Lawv tsuas xav tau lub roj teeb thaum siv los ua suab paj nruag.
hom ntawv dab tsi ntawm flash drive muaj?
Nws tsim nyog hais txog ntau hom flash drives uas muaj muag rau hnub no. Txhua qhov tshem tau tsav tau sib txawv raws li qhov kev pabcuam nws muab. Cov chav kawm dab tsi ntawm flash drives nyob hauv khw niaj hnub no raws li lawv txoj haujlwm?
Qee tus ntawm lawv tuaj yeem raug cais raws li cov kev pabcuam uas lawv muab, tab sis kuj tseem muaj qhov xav tau los nkag siab txog kev ua haujlwm ntawm txhua tus. Yog li ntawd, lub peev xwm ntawm flash drives tsis yog tib yamlos ntsuas thaum xaiv ib lub cuab yeej.
txheem tsav tsav
