Yiliphi ikhadi lememori okufanele ulikhethe: Sibutsetelo bamakilasi namafomethi amakhadi we-SD

Sawubona.

Cishe noma iyiphi idivaysi yesimanje (kungaba ifoni, ikhamera, ithebhulethi, njll.) Kudinga imemori khadi (noma ikhadi le-SD) ngokusebenza kwayo okugcwele. Manje emakethe ungathola inqwaba yezinhlobo zamakhadi wememori: ngaphezu kwalokho, ziyehluka ngentengo nevolumu kuphela. Futhi uma uthenga ikhadi le-SD elingalungile, insiza ingasebenza "kabi kakhulu" (ngokwesibonelo, ngeke ukwazi ukuqopha ividiyo ephelele ye-HD kwikhamera).

Kulesi sihloko, ngithanda ukubheka yonke imibuzo ejwayelekile mayelana namakhadi we-SD nokukhethwa kwawo kumadivayisi ahlukahlukene: ithebhulethi, ikhamera, ikhamera, ifoni. Ngiyethemba ulwazi luzosiza ekufundeni kabanzi kwebhulogi.

Amasayizi ekhadi lememori

Amakhadi wememori atholakala ngosayizi abathathu abehlukene (bheka. Umdwebo 1):

• - I-MicroSD: uhlobo oludumile lwekhadi. Kusetshenziswa ocingweni, ezibhebheni nakwamanye amadivayisi aphathekayo. Imemori khadi Ubukhulu: 11x15mm;
• - I-MiniSD: uhlobo lwekhadi olungathandeki, olutholakala, ngokwesibonelo, kubadlali be-mp3, amafoni. Ubukhulu bekhadi: 21.5x20mm;
• - I-SD: mhlawumbe uhlobo oludumile kakhulu olusetshenziswa kumakhamera, ama-camcorder, amaqoshwa, njll. Cishe wonke ama-laptops anamuhla namakhompyutha afakwe abafundi bamakhadi okuvumela ukuthi ufunde lolu hlobo lwekhadi. Ubukhulu bekhadi: 32x24mm.

U-fig. 1. Izici zezimpawu zamakhadi we-SD

Isaziso esibalulekile!Naphezu kweqiniso lokuthi lapho uthenga, ikhadi le-microSD (ngokwesibonelo) lifaka i-adaptha (i-Adapter) (bheka i-Fig. 2), ayituswa ukuyisebenzisa esikhundleni sekhadi le-SD elijwayelekile. Iqiniso ngukuthi, njengomthetho, iMicroSD inciphile kune-SD, okusho ukuthi iMicSS efakwe ku-camcorder ene-adaptha ngeke ivume ukuqoshwa kwe-Full HD video (ngokwesibonelo). Ngakho-ke, kufanele ukhethe uhlobo lwekhadi ngokuya ngezidingo zomenzi zedivayisi ethengelwe yona.

Ijubane noma isigaba Amakhadi wememori we-SD

Ipharamitha ebaluleke kakhulu yanoma iyiphi imemori khadi. Iqiniso ukuthi hhayi kuphela inani lekhadi lememori lincike esivinini, kepha futhi nasekusebenziseni kwayo.

Ijubane kwimemori khadi, imvamisa, ikhonjiswa ngumphindaphinda (noma faka isigaba sememori khadi. Ngendlela, abaphindaphindayo kanye nesigaba sememori khadi "baxhumene" komunye nomunye, bheka ithebula elingezansi).

Abakhiqizi abahlukahlukene bamaka amakhadi ngendlela ehlukile. Ukwenza isibonelo, emkhiwaneni. I-3 ikhombisa imemori khadi ene-class 6 - ijubane layo ku-acc. netafula elingenhla, ngu-6 Mb / s.

U-fig. 3. Iklasi lekhadi le-SD elidlulisiwe - isigaba 6

Abanye abakhiqizi abakhombisi isigaba kuphela kwimemori khadi, kodwa futhi nesivinini sayo (bheka. Umd. 4).

U-fig. 4. Ijubane likhonjiswa ekhadini le-SD

Yisiphi isigaba semephu esivumelana nokuthi imuphi umsebenzi ongatholakala etafuleni elingezansi (bheka Fig. 5).

U-fig. 5. Isigaba nenhloso yamakhadi wememori

Ngendlela, ngiphinda ngidonse ukunaka emniningwaneni owodwa. Lapho uthenga imemori khadi, bheka izidingo zedivayisi ukuthi iliphi iklasi elidinga ukusebenza okujwayelekile.

Isizukulwane sekhadi lememori

Kunezizukulwane ezine zamakhadi wememori:

• SD 1.0 - kusuka ku-8 MB kuye ku-2 GB;
• SD 1.1 -ukufika ku-4 GB;
• I-Sdhc - kufinyelela ku-32 GB;
• I-Sdxc - Kufika ku-2 TB.

Ziyahluka ngevolumu, ijubane, futhi zibuyela emuva ziyahambisana nomunye *.

Kunokungafani okubalulekile kulokhu: idivaysi esekela ukufunda amakhadi we-SDHC izokwazi ukufunda womabili amakhadi we-SD 1.1 namakhadi we-SD 1.0, kodwa ngeke ikwazi ukubona ikhadi le-SDXC.

Ungabheka kanjani ubukhulu bangempela kanye nesigaba sememori khadi

Kwesinye isikhathi akukho okukhonjisiwe ekhadini lememori, okusho ukuthi asihloniphi ivolumu yangempela noma isigaba sangempela ngaphandle kokuhlolwa. Kukhona into eyodwa enhle yokuhlola - H2testw.

I-H2testw

Iwebhusayithi esemthethweni: //www.heise.de/download/h2testw.html

Ukusetshenziswa okuncane kokuhlola amakhadi wememori. Kuzoba wusizo ngokuthengisa abathengisi abangathembekile kanye nabakhiqizi bamakhadi wememori akhombisa amapharamitha wemikhiqizo yabo overestimated. Hhayi, futhi nokuhlola "amakhadi we-SD angaziwa"

-

Ngemuva kokuqala isivivinyo, uzobona ngewindi elifanayo nalesisithombe esingezansi (bheka. Fig. 6).

U-fig. 6. I-H2testw: bhala isivinini se-14.3 MByte / s, ubukhulu bangempela bememori khadi ngu-8.0 GByte.

Ukukhetha imemori khadi ngethebhulethi?

Amathebhulethi amaningi emakethe namuhla asekela amakhadi wememori we-SDHC (afika ku-32 GB). Kunamathebhulethi asekelwa i-SDXC, kepha mancane kakhulu futhi abiza kakhulu.

Uma ungahleleli ukudubula ividiyo esezingeni eliphakeme (noma unekhamera yokulungiswa okuphansi), khona-ke nememori khadi yesigaba 4 izokwanela ukuthi ithebhulethi isebenze ngokujwayelekile. Uma usahlela ukurekhoda ividiyo, ngincoma ukukhetha ikhadi lememori kusuka ebangeni le-6 kuye kwele-10. Njengomthetho, umehluko "wangempela" phakathi kwebanga le-16 nele-10 awubalulekanga kangako ukuthi ungawuhlawulela.

Ukukhetha imemori khadi yekhamera / ikhamera

Lapha, ukukhetha imemori khadi kufanele kusondele kakhulu. Iqiniso ngukuthi uma ufaka ikhadi elineklasi eliphansi kunalelo elifunwa yikhamera, idivaysi ingahle isebenze ngokungazwisiseki futhi ungakhohlwa ngokudubula ividiyo ngekhwalithi enhle.

Ngizokunikeza ucezu olulodwa lwezeluleko (futhi okubaluleke kakhulu, olusebenzayo oluyi-100%): vula iwebhusayithi esemthethweni yomenzi wekhamera, bese uyala abasebenzisi. Kufanele ibe nekhasi: “Amakhadi wememori anconyiwe” (okungukuthi amakhadi we-SD umakhi azihlolile!). Isibonelo sikhonjiswa emkhiwaneni. 7.

I-PS

Ithiphu yokugcina: lapho ukhetha imemori khadi, lalelisisa kumenzi wayo. Ngeke ngifune okungcono kakhulu phakathi kwabo, kepha ngincoma ukuthenga amakhadi kuphela kwimikhiqizo eyaziwayo: iSanDick, iTranscend, iToshiba, iPanasonic, i-Sony, njll.

Yilokho, wonke umsebenzi omuhle nokukhetha okulungile. Ngezengezo, njengasosikhathi sonke, ngizokubonga 🙂
