- kuj pheej yig.
- Muaj ruaj khov.
- Yuav ua tsis tau.
- Yuav poob rau hauv kev puas tsuaj.
- Kev txav ntawm lub cev ua rau cov no muaj kev cuam tshuam ntau dua li SSDs.
Magnetic storage yog hais txog txhua qhov chaw cia uas suav nrog lub hard disk. Txawm hais tias feem ntau cov tuam txhab hauv computer tab tom txav mus rau cov khoom siv hauv xeev (SSDs), cov khoom siv sib xyaw ua ke tseem siv tau, ob qho tib si hauv cov khoos phis tawj thiab hauv cov chaw khaws cia sab nraud thiab cov chaw txawb.
Magnetic cia ruaj khov thiab tuav cov ntaub ntawv ntau heev. Peev xwm yog ntsuas nyob rau hauv units zoo li terabytes. Ntawm qhov tsis zoo rau cov hard drive sab nraud yog lawv qhov tsis zoo rau lub cev puas tsuaj, xws li los ntawm hluav taws lossis lwm yam kev puas tsuaj. Tsis tas li ntawd, cov hlau nplaum sib nqus cia siab rau lub cev txav mus los, ua rau lawv muaj kev cuam tshuam rau kev ua haujlwm tsis zoo dua li SSDs. Ntau tus kws yees duab uas siv hard drives khaws cov tsav thib ob ntawm qhov chaw ruaj ntseg ntxiv.
Yog tias koj tab tom xav txog lub hard drive sab nraud, ib qho uas tuaj nrog lub kiv cua txias yog tsim nyog tus nqi ntxiv; cov disks yog nyob rau hauv qhov chaw uas yuav kub.
Solid-State Drives (SSDs)
- Qiet, ceev ceev.
- Tsis muaj qhov txav txav txhais tau tias muaj kev ntseeg siab dua thiab lub neej ntev dua.
- Me me ua rau cov khoom txav tau yooj yim.
-
Nyiaj ntau dua li sib nqus hard drives.
- Ntau lub cev muaj kev cuam tshuam ntau dua li huab cia.
SSDs siv circuits thiab, qee zaum, flash nco los khaws cov ntaub ntawv. Lawv tsis muaj qhov txav mus los thiab, yog li ntawd, nyob ntsiag to, nrawm dua, thiab txhim khu kev qha ntau dua li cov hard drives. Cov txiaj ntsig no tuaj ntawm tus nqi, tab sis koj yuav pom lawv tsim nyog tus nqi ntxiv thaum koj xav txog kev ua neej ntev, kev ruaj ntseg, thiab kev txav mus los.
Secure Digital (SD) Cards
- Me me thiab nqa tau.
- Tuav cov ntaub ntawv ntau ntawm cov hneev taw me me.
- tuaj yeem hloov pauv ntawm cov khoom siv sib xws, xws li koob yees duab thiab khoos phis tawj.
- Limited lifespans.
- Yooj yim rau misplace.
- Yooj yim puas.
SD phaib yog me me, cov duab plaub uas haum rau hauv cov khoom siv hluav taws xob thiab daim npav nyeem ntawv. Muaj nyob rau hauv ntau qhov ntau thiab tsawg, lawv tuaj yeem khaws cov ntaub ntawv ntau heev. Lawv qhov me me ua rau lawv txav tau yooj yim, tab sis qhov no kuj ua rau lawv yooj yim plam lossis yuam kev. Lawv muaj kev txwv tsis pub dhau lub neej, teev raws li lub zog qhib / tawm mus.
Qhov teeb meem zoo: Cov npav SD pheej yig yog qhov ua rau tsis ua haujlwm ntau dua li cov npe nrov thiab muaj npe nrov.

- Yooj yim ua thiab khaws cia.
- Inexpensive.
- Shareable.
- Yooj yim ploj lossis puas.
- muaj peev xwm.
- Tus lej ntawm cov khoom siv sib xws tau ploj zuj zus.
CDs, DVDs, thiab Blu-duab tshav discs yog cov cuab yeej kho qhov muag. Txhua yam muaj nyob hauv ntau hom R (nyeem nkaus xwb) thiab RW (rewriteable) hom:
- RW discs rewritable.
- R discs tuaj yeem hlawv ib zaug xwb, tab sis qhov no kuj txhais tau tias lawv tsis tuaj yeem sau tsis raug. Qhov nruab nrab, R discs ruaj khov nyob rau lub sijhawm ntev dua li RW discs.
Ntawm no yog ob peb lub peev xwm kom nco ntsoov:
- Standard CDs tuav 700 MB ntawm cov ntaub ntawv, uas txhais mus rau ib ncig ntawm 125 12-megapixel JPEG cov duab, lossis 40 12-megapixel RAW cov duab.
- Ib txheej DVDs tuav 4.7 GB ntawm cov ntaub ntawv, uas yog li ntawm rau lub sijhawm ntau dua li CD. Ob txheej txheej DVDs tuav 8.5 GB ntawm cov ntaub ntawv.
- Blu-ray disks tuav 25 GB ntawm cov ntaub ntawv ntawm ib txheej disks thiab ib ncig ntawm 50 GB ntawm ob txheej disks.
Feem ntau cov kev pab cuam hlawv disc tuaj nrog kev pov thawj kev xaiv uas yog qhov tseem ceeb rau kev ua raws, txawm hais tias nws txuas ntxiv cov txheej txheem ntawm kev hlawv lub disc. Thaum kuaj xyuas, qhov kev pab cuam kuaj xyuas tias cov ntaub ntawv hlawv rau hauv CD lossis DVD yog tib yam li cov ntaub ntawv pom hauv lub khoos phis tawj hard drive.
Yuav tsis tau hnov txog thaum hlawv CDs lossis DVDs, tshwj xeeb tshaj yog thaum siv lwm cov haujlwm. Thaum hlawv ib CD lossis DVD, kaw tag nrho lwm cov kev pab cuam, thiab siv cov ntaub ntawv pov thawj.
Qhov teeb meem loj ntawm no yog tias ntau lub khoos phis tawj (tshwj xeeb yog lub laptops) tsis xa nrog CD / DVD drives lawm. Tej zaum koj yuav xav tau yuav ib qho DVD tsav sab nraud los txuas ntxiv siv DVDs thiab CDs tom qab koj lub khoos phis tawj tom ntej hloov kho.
Cloud Storage

- muaj peev xwm.
Flash drives yooj yim heev, thiab lawv tuav cov ntaub ntawv ntau dua li yav dhau los. Lawv qhov me me ua rau lawv txaus nyiam khaws cia thiab sib koom ntau cov duab ib zaug. Raws li kev daws teeb meem rau lub sijhawm ntev, txawm li cas los xij, lawv tsis yog qhov kev xaiv zoo tshaj plaws vim tias lawv tuaj yeem raug puas lossis ploj tau yooj yim, thiab cov ntaub ntawv uas lawv tuav tau yooj yim dhau los lwv.
paub Muaj Peev Xwm Cia Koj Xav Tau
Rau cov khoom siv tshiab thiab cov kev pabcuam tshiab, qhov peev xwm khaws cia feem ntau ntsuas hauv terabytes (TB), tshaj li gigabytes (GB) thiab megabytes (MB) ntawm cov thev naus laus zis qub. 1 TB yog me ntsis ntau dua 1000 GB; muab lwm txoj hauv kev, 1 TB kev daws teeb meem khaws 1000 npaug ntau cov ntaub ntawv ntau dua li 1 GB.
Tus naj npawb ntawm cov duab koj khaws tau nyob ntawm lawv qhov kev daws teeb meem thiab hom. JPGs yog compressed thiab siv qhov chaw tsawg dua, thaum cov duab tua hauv RAW hom tsis yog compressed thiab loj dua. Piv txwv li, xav tias koj tab tom tua ntawm 16-megapixel daws teeb meem. Ib qho TB ntawm qhov chaw khaws cia muaj txog 183,000-j.webp
