Key Takeaways
- Ib txoj kev khaws cov ntaub ntawv tshiab tuaj yeem tso siab txog 500 terabytes ntawm lub disc.
- Kev tsim kho tshiab hauv kev cia tuaj yeem ua lub zog tsav tsheb tsis muaj tsheb thiab kev paub txog kev muaj tiag.
- Hard disk tseem tau loj dua thiab pheej yig dua.
Npaj khaws tag nrho koj cov ntaub ntawv hauv tsev.
Cov kws tshawb fawb tau tsim "5D" cov ntaub ntawv khaws cia thev naus laus zis uas tuaj yeem tso cai 500 terabytes ntawm cov ntaub ntawv sau rau hauv CD-qhov loj me ntawm cov iav disc. Nws yog ib feem ntawm qhov kev hloov pauv loj zuj zus hauv cov ntaub ntawv loj thiab pheej yig siv txoj hauv kev siv cov thev naus laus zis tshiab uas tuaj yeem ua kom muaj zog txhua yam los ntawm cov tsheb tsis muaj tsheb mus rau kev paub txog kev muaj tiag virtual.
"Cov ntaub ntawv zoo li cov roj crude ntawm cov hnub qub," Hang Liu, tus pab xibfwb ntawm hluav taws xob thiab computer engineering ntawm Stevens Institute of Technology, hais rau Lifewire hauv kev xam phaj email.
"Peb tuaj yeem tshem tawm kev nkag siab los ntawm cov ntaub ntawv raws li lawv tau muab tso rau hauv disk tag nrho. Cov kev nkag siab no yog qhov tseem ceeb tsis yog rau cov tuam txhab lag luam loj rau kev npaj cov tswv yim, tab sis [lawv] kuj txhawj xeeb txhua tus neeg lub neej txhua hnub."
Txhua yam ntawm Disc
Kev khaws cov ntaub ntawv ntawm lub disc yog ib txoj hauv kev khaws tag nrho koj cov ntaub ntawv ntawm koj lub ntsis ntiv tes. Nyob rau hauv ib daim ntawv tsis ntev los no, cov kws tshawb fawb tau piav qhia txog ib txoj hauv kev sau cov ntaub ntawv uas suav nrog ob lub qhov muag pom thiab peb qhov ntev.
Cov discs tshiab yog tsim los siv cov lasers ceev thiab muaj ntau dua 10,000 zaug denser dua Blu-duab tshav. Txoj hauv kev tuaj yeem sau nrawm ntawm 1 lab voxels ib ob, sib npaug rau sau txog 230 kilobytes ntawm cov ntaub ntawv (ntau dua 100 nplooj ntawv ntawm cov ntawv) ib ob.
Cov kws tshawb fawb tau siv lawv txoj kev tshiab los sau 5 gigabytes ntawm cov ntaub ntawv cov ntaub ntawv mus rau silica iav disc txog qhov loj ntawm cov pa compact disc nrog ze li 100% kev nyeem ntawv raug. Txhua lub voxel muaj plaub yam ntaub ntawv, thiab txhua ob lub suab sib raug rau cov ntawv nyeem. Nrog rau kev sau ntawv ceev muaj los ntawm txoj kev, lub disc tuaj yeem tuav 500 terabytes ntawm cov ntaub ntawv.
"Nrog rau cov txheej txheem tam sim no, peb muaj peev xwm khaws cov ntaub ntawv terabytes, uas tuaj yeem siv tau, piv txwv li, khaws cov ntaub ntawv los ntawm tus neeg lub DNA," Peter G. Kazansky, tus thawj coj ntawm pab pawg tshawb fawb, tau hais. hauv xov xwm tshaj tawm.
Tsis Tau Delete
Hard disc drives kuj tau loj dua thiab pheej yig dua, Jacky Lee, tus thawj coj ua lag luam ntawm cov neeg siv khoom siv hluav taws xob lub tuam txhab Toshiba, hais rau Lifewire. Piv txwv li, Toshiba siv hom microwave kaw ua ntej lub xyoo no los thawb HDD muaj peev xwm mus rau 18 terabytes hauv nws Nearline hard disk drives.
"Lub peev xwm loj dua tso cai rau cov neeg siv khoom muaj peev xwm los sib sau cov ntsiab lus digital los ntawm ntau lub cuab yeej rau hauv ib qho HDD," Lee ntxiv. "Qhov no ua rau nws yooj yim dua los npaj thiab khaws cov ntsiab lus tseem ceeb."
Cov ntaub ntawv zoo li cov roj crude ntawm hnub qub.
Solid-state disks muab kev nyeem ntawv nrawm dua thiab sau nrawm dua, muaj peev xwm loj dua, thiab muaj cov ntawv me me, sib dua, nyias, Allan Buxton, tus thawj coj ntawm forensics ntawm lub tuam txhab khaws ntaub ntawv SecureData, hais rau Lifewire. Ntawm qhov tod tes, hard disks tseem yeej ntawm kev them taus, muaj peev xwm, thiab txawm tias kev ua siab ntev.
"Cov neeg siv tshwm sim tawg ntawm kev siv huab cia thiab tswj hwm tus kheej cov chaw khaws cia, nrog rau yav tom ntej yuav ua kom zoo dua tam sim ntawm kev nce qib hauv hard disk thev naus laus zis," Buxton hais.
Cov chaw muab huab cia kuj tseem tab tom hloov mus rau kev khaws cia sai dua. Cov ntaub ntawv ntau dua txhim kho tag nrho cov kev ua haujlwm khaws cia, suav nrog cov chaw khaws cia, thiab tso cai rau kev tsav tsheb nrawm dua thiab rov ua kom muaj zog ntau dua, cov kws tshaj lij thev naus laus zis thiab IEEE tus khub Tom Coughlin hais rau Lifewire.
Cov HDDs loj dua yuav pab khaws cov ntaub ntawv ntawm tus nqi qis, txhawb kom khaws cov ntaub ntawv daws teeb meem ntau dua thiab cov ntaub ntawv ntau dua.
Lwm qhov kev hloov tshiab tsis ntev los no yog Microsoft's Project Silica, uas siv ultrafast laser optics khaws cov ntaub ntawv. Nws muab qhov nruab nrab cia uas muaj peev xwm kav tau ntau txhiab xyoo yam tsis muaj degradation.
Muaj ntau qhov chaw khaws cia tuaj yeem qhib qhov muaj peev xwm tshiab rau cov neeg siv. Piv txwv li, Coughlin tau hais tias cov ntawv thov tuaj yeem tso siab rau ntau cov ntaub ntawv los rho tawm cov kev nkag siab thiab txiav txim siab zoo tshaj plaws, xws li kev kawm tsheb tsis muaj tsheb los ntawm tag nrho cov ntaub ntawv tsheb khaws cia. Kev khaws cov ntaub ntawv dav dav ntxiv tseem yuav pub rau yav tom ntej kev txawj ntse txawj ntse thiab ua rau cov ntawv thov AI zoo dua.
"Kev muaj peev xwm ntau dua, kev ua tau zoo dua, qis dua cov thev naus laus zis ntawm txhua hom yuav txhawb kom tsim kom muaj kev paub ntau dua AR / VR uas yuav ua rau muaj kev lom zem ntau dua, kev kawm, thiab txoj hauv kev tshiab rau tib neeg sib cuam tshuam nrog lwm tus, "nws ntxiv.
