SD Card Siv Thiab Hloov Tiv Thaiv
Nov 23, 2022| SD nco daim npav (Secure Digital Memory Card) yog lub cim tshiab ntawm cov khoom siv ceev ceev raws li semiconductor flash nco. Lub tshuab ntawm SD daim npav yog tsim los ntawm MMC daim npav (Multi Media Card) hom ntawv, thiab SDIO (SD Input/Output) daim npav yog tsim los ntawm lub hauv paus ntawm SD nco daim card. Qhov kev sib raug zoo no suav nrog kev siv tshuab, hluav taws xob, hluav taws xob, teeb liab thiab software, SD thiab SDIO phaib feem ntau hu ua SD daim npav nco.
SD daim npav muaj peev xwm nco tau siab, cov ntaub ntawv hloov pauv ceev ceev, kev txav tau yooj yim thiab kev ruaj ntseg zoo, nws tau siv dav hauv cov khoom siv nqa tau yooj yim, xws li cov koob yees duab digital, ntsiav tshuaj PCs thiab multimedia players, thiab lwm yam.
Cov qauv ntawm SD daim npav tuaj yeem ua kom muaj kev ruaj ntseg ntawm cov ntaub ntawv xa mus rau digital, thiab nws kuj tseem yooj yim rau kev hloov kho, yog li nws muaj ntau yam kev siv. Cov ntaub ntawv multimedia xws li suab paj nruag thiab tsos tuaj yeem yooj yim khaws cia rau SD daim npav. Muaj ntau hom SD phaib nyob rau hauv kev ua lag luam xws li: SANDISK, Kingmax, Panasonic thiab Kingston.
Raws li hom tshiab ntawm cov cuab yeej cia, SD daim npav muaj cov yam ntxwv hauv qab no:
● Muaj peev xwm cia siab, feem ntau siv muaj peev xwm: 8GB, 16GB, 32GB, 128GB, 256GB, thiab lwm yam.
● Built-in encryption technology, yoog raws txoj cai tiv thaiv kev ua haujlwm raws li SDMI raws tu qauv.
● Kev xa cov ntaub ntawv ceev ceev; qhov siab tshaj plaws nyeem thiab sau tus nqi yog 100MB / s.
●Nws yog lub teeb thiab me me, nqa tau yooj yim, thiab muaj kev cuam tshuam tsis zoo.
Los ntawm daim duab, feem ntau muaj qhov hloov ntawm sab xis ntawm SD daim npav, uas yog qhov hloov pauv kev tiv thaiv overwrite, thaum daim npav MMC tsis ua. Thaum qhov hloov pauv kev tiv thaiv overwrite raug kaw, SD daim npav yuav nyob rau hauv kev tiv thaiv overwrite, thiab cov ntaub ntawv tsuas tuaj yeem nyeem tau. Thaum lub overwrite tiv thaiv hloov nyob rau hauv lub Upper txoj hauj lwm, cov ntaub ntawv yuav tsum tau overwritten. Txij li qhov hloov kev tiv thaiv no yog xaiv tau, qee lub npe ntawm SD daim npav tsis muaj qhov kev tiv thaiv no.
Lub hauv paus ntsiab lus ntawm kev tiv thaiv overwrite hloov yog zoo ib yam li kev tiv thaiv overwrite ntawm cov kab xev, VHS video tapes, thiab computer disks. Lub xeev kaw txhais tau hais tias nws tuaj yeem sau tau, thaum lub xeev qhib txhais tau tias nws muaj kev tiv thaiv.
Yog tias qhov hloov pauv tau tawg, daim npav tsuas tuaj yeem dhau los ua daim ntawv tiv thaiv kev nyeem nkaus xwb. Ib txoj kev nyob ib ncig ntawm qhov no yog kaw lub thais kom daim npav yuav sau tau ib txwm.
SD cards yog siv nyob rau hauv cov nram qab no portable digital devices:
Lub koob yees duab digital SD daim npav
Lub koob yees duab digital SD daim npav
●Digital lub koob yees duab khaws cov duab thiab yeeb yaj duab
●Digital camcorder khaws cov duab thiab yeeb yaj duab
●Tablet PC khaws ntau yam ntaub ntawv
● Txawb xov tooj khaws cov duab, ringtones, suab paj nruag, video clips thiab lwm yam ntaub ntawv
● Multimedia player
SD phaib feem ntau yog siv rau hauv MP3 players, digital video koob yees duab, digital koob yees duab, thiab lwm yam, thiab kuj tseem siv rau hauv phau computers. SD daim npav tau tsim sai heev hauv xyoo 2013, thiab nws tau pib hem kev lag luam ntawm CF daim npav. Txawm li cas los xij, nws yuav tsum raug sau tseg tias ntawm qee yam khoom xws li xov tooj ntawm tes, SD phaib thiab MMC phaib tsis sib xws. SD phaib xyoo 2013 muaj peev xwm ntawm 8MB txog 128GB.
Ekev tuav pov hwm
Khoos phis tawj daim npav nyeem ntawv zam kev tuav txoj kev:
①Yog tias daim npav SD tuaj yeem xauj cov duab ib txwm nyob hauv lub koob yees duab, tab sis nws tsis tuaj yeem lees paub thaum nws tso rau hauv lub khoos phis tawj, nws yog qhov tshwm sim los ntawm qhov tsis sib xws ntawm tus tsav tsheb ntawm SD lub qhov (socket). Nrhiav qhov tseeb SD card tsav tsheb thiab hloov kho nws.
② Tom qab hloov tshiab, yog tias muaj lub cim daj ceeb toom nyob rau hauv tus thawj tswj ntaus ntawv, thiab software nrog USB disk tiv thaiv muaj nuj nqi raug ntsia rau hauv lub computer, nws yuav yog vim tsis sib xws, thiab nws yuav raug lees paub tom qab rov pib lub computer.
Kev tu siab
1. Yog tias SD daim npav siv lub koob yees duab ib txwm siv, thiab cov duab thaij hauv lub khoos phis tawj raug saib, thiab cov duab yuav tsum tau rov qab, thov luam cov duab rau hauv lub computer ua ntej ua haujlwm. Yog tias daim npav SD muab tso rau hauv lub koob yees duab saib cov duab cuam tshuam, nws yuav tsis tuaj yeem saib cov duab. Tom qab ib tug loj tus naj npawb ntawm cov duab raug hloov, SD card tej zaum yuav "tus tuag tes tuag taw", thiab nws yuav tsum tau formatted ua ntej nws yuav siv tau ib txwm.
2. Yog tias daim npav SD khov lossis khov thaum tua hauv lub koob yees duab, nws yuav yog tias SD daim npav tsis raug lossis tau tas sijhawm. Thov siv daim npav nyeem ntawv kom xa tawm cov ntsiab lus ntawm daim npav kom txuag thiab tom qab ntawd format nws. (Yog tias nws yog daim npav tsis zoo, nws yuav qeeb qeeb rau kev nyeem thiab luam), qee qhov tuaj yeem siv tau ib txwm tom qab formatting, koj tuaj yeem siv qee qhov kho software, nws yuav faib qhov tsis zoo rau hauv ib qho kev faib cais, thiab tom qab ntawd nkaum nws. Tab sis nws raug nquahu kom tsis txhob khaws cov ntaub ntawv tseem ceeb rau kev siv, vim tias lwm qhov chaw kuj yuav raug huab cua thiab yuav tsis ntev.
3. Daim npav SD muaj me ntsis zais cia. Yog tias koj ua txhaum SD daim npav lossis ua txhaum nws thiab siv tsis tau, tsis txhob maj muab pov tseg ntawm daim npav "scrap". Thaum koj disassemble saum npoo ntawm daim npav SD ua tib zoo, Koj yuav pom tias muaj daim npav TF me me "pob ntseg" hauv, uas tuaj yeem siv los ntawm ntau lub xov tooj ntawm tes, thiab nws kuj tuaj yeem siv nrog TF adapter card chaw nres nkoj rau SD. daim npav. (Daim npav no yog daim npav SD tsis zoo. SD daim npav feem ntau yog tsim los ntawm PCBA ntxiv rau kev tswj xyuas tseem ceeb ntxiv rau FLASH, tsis yog TF daim npav hloov dua siab tshiab)
