Gjennom \u00e5rene har flyttbar lagring kommet i mange former \u2013 noen med litt mer finesse enn andre.<\/p>\n<p>Dette kan kanskje komme som en overraskelse, men den f\u00f8rste formen for flyttbar lagring var faktisk en punchkort. Kortet ble designet p\u00e5 1950-tallet for \u00e5 registrere ulike typer data som deretter ble matet inn i en datamaskin. Maskinen ville lese p\u00e5 punchene og tolke dataene.<\/p>\n<p>Derfra utviklet seg magnetb\u00e5nd. Denne innovasjonen dominerte databehandlingen p\u00e5 1960- og 1970-tallet, men ble til slutt erstattet av disketter og CD-ROM-er p\u00e5 1980- og 1990-tallet. Men s\u00e5 snart det nye \u00e5rtusenet begynte, krevde brukere og deres enheter en ny type lagring: flash.<\/p>\n<p>Flashminne kommer i mange former. Denne typen lagring er oftest forbundet med USB-minnepinner, men flashteknologi brukes ogs\u00e5 p\u00e5 SD-kort.<\/p>\n<h2>Hva er et SD-kort?<\/h2>\n<p>SD-kort eller sikre digitale kort er en liten form for flashminne som har blitt popul\u00e6rt med introduksjonen av digitale kameraer og smarttelefoner. De fleste av disse enhetene krever et SD-kort for \u00e5 lagre dataene sine. Kortet, som ofte er p\u00e5 st\u00f8rrelse med en kvart eller mindre, kan enkelt flyttes fra en enhet til en annen for \u00e5 raskt og enkelt overf\u00f8re data.<\/p>\n<p>Disse enhetene har mye kraft og lagringsplass for sin st\u00f8rrelse. Sammenlignet med punchkortene og magnetb\u00e5ndene fra tidligere ti\u00e5r er SD-kort en m\u00e5te \u00e5 m\u00e5le hvor mye databehandling som har endret seg over tid.<\/p>\n<p>Men hva f\u00e5r SD-kortene til \u00e5 fungere? Finnes det forskjellige typer SD-kort? Hva b\u00f8r en bruker gj\u00f8re hvis SD-kortet deres svikter? Les videre for \u00e5 l\u00e6re mer.<\/p>\n<h2>Hvordan fungerer et SD-kort?<\/h2>\n<p>Som tidligere nevnt st\u00e5r SD for \u201csecure digital\u201d, men hva er egentlig en SD-kort? For \u00e5 forst\u00e5 SD-kort og hvordan de fungerer, m\u00e5 du f\u00f8rst forst\u00e5 flashminne.<\/p>\n<p>Flash-stasjoner er lagringsenheter i solid-state-teknologi, noe som betyr at de ikke har bevegelige, mekaniske deler. Disse enhetene er 100 prosent elektroniske og kan skrive, slette og omskrive data. Det som skiller flash-lagring fra andre lagringsenheter er muligheten til \u00e5 utf\u00f8re alle disse handlingene p\u00e5 en begrenset mengde plass, ettersom flash-lagring er kjent for \u00e5 v\u00e6re liten og ekstremt b\u00e6rbar.<\/p>\n<p>SD-kort er en type flashlagring. De kommer vanligvis i st\u00f8rrelsen p\u00e5 et frimerke eller lignende og er mindre enn en tiendedel av en tomme tykk. De bruker et lite kretskort og reagerer p\u00e5 en elektrisk str\u00f8m for \u00e5 lagre data. Denne samme teknologien gj\u00f8r det mulig \u00e5 hente ut dataene med en hvilken som helst enhet med en SD-kortleser.<\/p>\n<p>De fleste SD-kort har SDHC-protokollen, som betyr \u201csikker data med h\u00f8y kapasitet\u201d. Denne protokollen gj\u00f8r det mulig for SD-kort \u00e5 lagre opptil 32 GB data. SDHC var en gjennombruddsfunksjon for SD-kort, noe som gjorde dem til det foretrukne valget for mange forbruksvarer p\u00e5 grunn av forholdet mellom stor lagringskapasitet og st\u00f8rrelse (og pris).<\/p>\n<p>Imidlertid kan det snart finnes enda st\u00f8rre SD-kort p\u00e5 markedet. Et nytt protokoll kalt secure data extended capacity (SDXC) gj\u00f8r det mulig for SD-kort \u00e5 lagre opptil 2 TB data. Denne teknologien er fortsatt under utvikling, men vil snart f\u00f8re til SD-kort med enda st\u00f8rre lagringskapasitet.<\/p>\n<h2>Hva er typene av SD-kort?<\/h2>\n<p>Som diskutert finnes det ulike protokoller (SDHC og SDXC) for SD-kort, noe som absolutt utgj\u00f8r to typer. Men det finnes ogs\u00e5 flere forskjellige st\u00f8rrelser. SD-kort kommer i vanlig, mini og micro.<\/p>\n<p>Da SD-kort kom p\u00e5 markedet for f\u00f8rste gang, var den vanlige st\u00f8rrelsen ganske popul\u00e6r og ble generelt ansett som standard. Den vanlige st\u00f8rrelsen er 32 x 24 mm, noe som passer i de fleste datamaskiner og digitale kameraer. Konsumentene ble raskt forelsket i denne kompakte lagringsl\u00f8sningen, og etter hvert som enhetene ble mindre, ble SD-kortene ogs\u00e5 mindre.<\/p>\n<p>Mini-SD-kort ble utviklet for \u00e5 passe i mindre digitale kameraer og andre lignende medier. De m\u00e5ler 21,5 x 20 mm. Enheter som bare har en vanlig SD-kortport kan enkelt bruke en adapter for \u00e5 koble mini-SD-kort til en vanlig port. Men denne typen SD-kort brukes sjelden i dag, ettersom mikro-SD-kortet, en mye mindre variant av mini-SD-kortet, har overhalet det lille flashlagringsmarkedet.<\/p>\n<p>Mikro-SD-kortene er hittil de minste kortene, med en st\u00f8rrelse p\u00e5 15 x 11 mm og en tykkelse p\u00e5 kun 1 mm. N\u00e5r mobiltelefoner ble smartere og mindre, var det behov for en enda mindre lagringsl\u00f8sning. Mikro-SD-kort passer godt til dette form\u00e5let og brukes ofte for \u00e5 utvide de innebygde lagringskapasitetene i smarttelefoner og andre sm\u00e5 enheter.<\/p>\n<h2>Hvor mye koster SD-kort?<\/h2>\n<p>Da SD-kortene f\u00f8rst kom p\u00e5 markedet, var de ganske dyre. For bare 15 \u00e5r siden kunne du lett bruke $100 p\u00e5 et mini-SD-kort p\u00e5 4 GB. Men de dager er for lengst forbi, og som med de fleste lagringsenheter har kostnaden for SD-kortene g\u00e5tt betydelig ned.<\/p>\n<p>Her er en oversikt over hva du kan forvente \u00e5 betale for et SD-kort i 2020:<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_row-fluid wpex-relative\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div  class=\"wpb_single_image wpb_content_element vc_align_ wpb_content_element\">\n\t\t\n\t\t<figure class=\"wpb_wrapper vc_figure\">\n\t\t\t<div class=\"vc_single_image-wrapper   vc_box_border_grey\"><img width=\"1890\" height=\"560\" src=\"https:\/\/drivesaversdatarecovery.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-27-at-1.03.41-PM.png\" class=\"vc_single_image-img attachment-full\" alt=\"\" title=\"Skjermbilde 2020-04-27 klokken 13.03.41\" srcset=\"https:\/\/drivesaversdatarecovery.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-27-at-1.03.41-PM.png 1890w, https:\/\/drivesaversdatarecovery.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-27-at-1.03.41-PM-300x89.png 300w, https:\/\/drivesaversdatarecovery.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-27-at-1.03.41-PM-1024x303.png 1024w, https:\/\/drivesaversdatarecovery.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-27-at-1.03.41-PM-768x228.png 768w, https:\/\/drivesaversdatarecovery.com\/wp-content\/uploads\/2020\/04\/Screen-Shot-2020-04-27-at-1.03.41-PM-1536x455.png 1536w\" sizes=\"(max-width: 1890px) 100vw, 1890px\" \/><\/div>\n\t\t<\/figure>\n\t<\/div>\n<\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_row-fluid wpex-relative\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p>Som du kan se, er prisene sammenlignbare, og i noen tilfeller er mikroSD-kortet rimeligere enn vanlig SD-kort.
