Ngokunokwenzeka, ubukholelwa ukuba ukuthenga ikhadi le-SD elincinci okanye elinye lilinganiselwe ekuthengeni eyona memori khadi inexabiso elaneleyo. Noko ke, akunjalo. Ngoku Iifowuni eziphathwayo sele zisezingeni eliphezulu, kwaye ziyakwazi ukurekhoda kwi-4K. Yeyiphi i-micro SD yememori khadi onokuthi uyithenge ukurekhoda ividiyo ye-4K ngeselfowuni yakho?
Rekhoda umgangatho wevidiyo ye-4K
Kungenzeka ukuba ifowuni yakho iyakwazi ukurekhoda ividiyo ye-4K. Nangona kunjalo, ukuba awunayo imemori khadi, ividiyo iya kugcinwa kwimemori yangaphakathi ye-smartphone. Ividiyo ye-4K inokuthatha indawo eninzi, ke ukuba sifuna ngokwenene ukurekhoda iividiyo ze-4K, kuya kufuneka sithenge imemori khadi. Kwaye ukuba sifuna iividiyo ze-4K zirekhodwe ngomgangatho, ngoko kuya kufuneka sithenge imemori khadi yomgangatho owaneleyo. Ukuba imemori khadi ayinayo isantya sokubhala ngokukhawuleza, ngoko siya kubona ukusikwa kumfanekiso wevidiyo, kwaye kungenxa yokuba ifowuni ephathwayo ayiyi kukwazi ukugcina ividiyo njengoko ibirekhoda. Ngoko, Yiyiphi imemori khadi esifanele siyithenge ukuba sifuna ukurekhoda umgangatho we-4K?
Yeyiphi ibitrate irekhodi yakho yeselula?
Ngokwenene kuxhomekeke kwi bitrate ukuba iirekhodi zakho mobile. I-bitrate ngumlinganiselo wevolumu ehlala ifayile njengoko isenziwa. Umzekelo, i-bitrate ye-20 MB/s iya kuthetha ukuba i-20 MB iya kuveliswa ngesekondi nganye yevidiyo. Lo ngumzekelo, i-bitrate iyahluka ukusuka kwifowuni enye ukuya kwenye, ukusuka kwikhodekhi yevidiyo ukuya kwenye, kwaye kuxhomekeke kwizakhelo ngesekhondi esirekhoda kuyo. Ngokubanzi, eyona nto ilungileyo kukuthenga ikhadi elihambelana neyona bitrate iphezulu yeyona ndlela iphezulu yevidiyo yemowudi yeselula yethu. Ke, masicinge ukuba ifowuni yethu iyakwazi ukurekhoda kwi-4K kwiifreyimu ezingama-60 ngomzuzwana. Kuya kufuneka sifumane kwidatha yezobuchwepheshe ye-smartphone ukuba yeyiphi i-bitrate yevidiyo ekulo mgangatho kwi-smartphone yethu.
Kodwa ukuba ufunda eli nqaku kungenxa yokuba: a) awufuni ukwenza nzima kakhulu izinto ngokufunda ukuba kutheni uthenga imemori khadi okanye enye; kwaye b) ufuna ukwazi ukuba ngawaphi amakhadi angawona angcono.
Yeyiphi imemori khadi onokuyithenga?
Nangona kuyinyani ukuba akunakwenzeka ukuthetha ukuba yeyiphi imemori khadi egqibeleleyo, kwaye mhlawumbi kwiifowuni eziphathwayo eziza kuboniswa kunyaka ozayo, esi sithuba asisayi kuba luncedo ekurekhodweni kwi-4K (into eya kwenzeka ukuba iifowuni eziphathwayo ziyakwazi. Ukurekhoda kwi-4K kwiifreyimu ze-120 ngomzuzwana), sinokuqinisekisa ukuba zonke iimemori khadi ziyahambelana Itekhnoloji ye-U3 iya kuba luncedo ekurekhodweni kwi-4K. Amakhadi ahambelana nobuchwephesha be-U3 anelogo ekwikhadi ngokwalo, nto leyo eyenza kube lula ukuyifumana. I iimemori khadi ezine-logo ye-U3 ziqinisekisa ukuba isantya sokubhala sidlula i-30 MB/s.
Ukurekhodwa kweselula kwi-4K kwiifreyimu ze-30 ngesekhondi kuya kuba ne-bitrate phakathi kwe-30 kunye ne-60 Mbps (megabits ngesekhondi). Ukukhumbula ukuba i-byte yi-8 bits, kufuneka nje uhlukanise ubuninzi ngo-8. Sifuna isantya sokubhala esiphezulu se-7,5 MB / s. Amakhadi ane I-logo ye-U1 iqinisekisa ukuba banesantya sokubhala esidlula i-10 MB / s. Kananjalo bangamakhadi odidi lwe-10, abonisa uphawu lweC10. Ngokwesiqhelo, iimemori khadi zinokufaka zonke iilogo ezahlukeneyo.
Ukuba uthenge isiphelo esiphezulu samva nje kwimarike, Ingcebiso yam kukuba uthenge ikhadi elinophawu lwe-U3. Sinokuthenga ikhadi elinjalo ngexabiso malunga ne-euro ye-55, kunye ne-64 GB yamandla. Ukuba uthenge ifowuni ebiza ngolo hlobo, kuyaqondakala ukuba uthenge imemori khadi esemgangathweni. Ukuba uthenge ifowuni ephathwayo yodidi oluphakathi, thenga ikhadi leClass 10 elifikelelekayo. Kule meko, kunokwenzeka ukufumana amakhadi e-32 GB malunga ne-euro eyi-15. Nokuba ifowuni yakho irekhoda i-4K, ayinakuze, nangohlaziyo, irekhode i-4K kwiifreyimu ezingama-60 ngomzuzwana, ke awuyi kufuna imemori khadi enesantya esiphezulu sokubhala.
