Sony 4GB Memory Stick - PRO Duo Card - MSMT4GN

Product Information

This is obviously my personal experience with these brands and cards – your mileage might certainly vary and you might find one brand to be more reliable than another based on cards that have failed you in the past. It is also worth pointing out that memory card specifications and features change every year, so if you have experienced a problem with one particular model, it does not mean that the next model will be as bad.

Some people choose to move contents of memory cards instead of formatting them. That’s a perfectly fine practice and there is nothing wrong with doing that, but I personally stay away from delete and move operations on my memory cards. Reading contents of a memory card is always going to be faster than read + delete. 8. Don’t Rush Deleting Images From Your Camera Az utóbbi időkben a Secure Digital (SD) kártya a legelterjedtebb, mivel a korábban (főként mobiltelefonokban) alkalmazott MMC kártyáknál sokkal nagyobb adatátviteli sebességet tesz lehetővé. A hagyományos SD-kártya mellett később megjelentek a kisebb méretű MiniSD, majd a még kisebb MicroSD kártyák is. Ezeket a fényképezőgépek, videókamerák és mobiltelefonok is képesek közvetlenül írni és olvasni, a külső kártyaolvasókban azonban csak kiegészítő adapterrel használhatók. A kártyák sebességét a típusuk utáni class 2, class 4, class 6, class 8, class 10 adja meg, amiben a class utáni számok a kártyák minimum írási/olvasási sebességét jelölik MB/s-ban. There have been cases with some cameras being incompatible with particular memory cards and write operations would take excessively long as a result. Some photographers were not patient enough to wait for the light to turn off and they would take the battery out, which often resulted in memory card corruption. If you take a picture and it takes over 5 seconds for the memory light to go off, you might want to stop using that memory card and replace it with a different one. Same build as microSD/microSDHC, but greater capacity and transfer speed, 32GB and higher. Standard goes up to 2TB (not compatible with older host devices). Thinner (3.3mm), flash only, now up to 512 GB, although standard goes up to 128 PB since CF 5.0 [2]

Emellett még a mérés módszerei sincsenek szabványosítva; a tesztek kevesebb nagyobb méretű fájlt gyorsabban visznek át, mint több kisebb, de összességében ugyanakkora méretű fájlt. A különböző gyártók másként, vagy egyáltalán nem definiálják a sebességet. Egyesek az írási, míg mások az olvasási sebességet veszik alapul, és vannak, akik egyszerre mindkettőt figyelembe akarják venni, és adatátviteli sebességről beszélnek. A neves gyártók azonban mindig megadják a maguk pontos definícióját. [ forrás?] Összehasonlítás [ szerkesztés ] Típus X (requires an e Xternal adapter) – Technically the same as E, but such adapter usually consists of 2 parts: a pseudo-card with pin routing and physical enclosure size that perfectly match the target slot and a break-out box (a card reader) that holds a real card. Such adapter is the least comfortable to use. Memory Card Capacity– The capacity of the memory card is typically displayed in large numbers. As can be seen here, this memory card has a total capacity of 128 GB.

Memory Cards and Everything You Need to Know About Them Memory Cards and Everything You Need to Know About Them

Every now and then we all delete something from the card. And that leads me to the second mistake author made here. By saying that it is OK to delete data from the card, he was misleading. I once formatted a used card with photos I needed, because I did not label or mark it after it was used. While you can recover photos from formatted cards, if you happen to write anything over the formatted card, the images you had before will not be recoverable, especially if you fill up the card with new images. D ( Directly compatible) – A card may be used in such a slot directly, without any adapters. Best possible compatibility.

Maximum Read Speed– This is the maximum sequential read speed the memory card is capable of in Mega Bytes per second (MB/sec). Please note that write speeds are rarely ever published on memory cards and you will need to find that information in memory card manual or listed specifications. In this case, the maximum read speed of the SD card is 300 MB/sec. A memóriakártyák sebességét nem közvetlenül kB/s-ban adják meg, hanem a CD-k olvasási sebességéhez mérik. Például: SD card 50x = ca. 7,5 MB/s. Az egyszeres sebesség 150 kB/s. A sebességnek ez a megadási módja a CD-égetésből terjedt át más eszközökre. A High Speed vagy a HyperSpeed kifejezések mögött nincs szabvány, ami megmondja, hogy milyen gyorsnak is kell lenniük.
