If someone has set, when we buy a camera card Photos, besides the size of the memory are other names that come with flash cards (SD, XD, CF, MS, etc.).
We will divide in speed, capacity and improvements. Then at the end add a "What do I need?" to resolve any doubts.
Speed \u200b\u200b- "classes"
The first SD cards have in the upper right side (usually on this side) a number surrounded by a circle. The numbers can be 2, 4, 6 and 10 and then is part of a "1" contained in a U. Well
numbers mean the minimum speed , ensure that the manufacturer that will work card, that is, if you have a 2, the card at least have to read and write data at 2MB / s.
Then there are the cards that have 1, one does not mean working at 1MB / s as above, in contrast with 1 cards are the professional and means that they will work at full power, up to 104MB / s. Speed \u200b\u200bUHS are called Class 1. These cards work in electronic devices intended for such use, typically professional video cameras with a huge recording rate.
other hand there are manufacturers who even numbered card with a class on the left side (usually on this site) put a speed "15 MB / s "," 22 MB / s "," 30MB / s ", etc. This means that although the rate your card manufacturer in a class, for example 6, ensures that your card is not going a6, will go to the MB that says (15, 22, 30, 50 ...). This exception to the classification is usually for business cards, people who need to secure greater speed.
Capades - SD, SDHC and SDXC
standards are first born SD, SDHC, and finally after SDXC. These standards are for defining the amount of memory you can have the cards.
SD: You can make cards up to 2GB .
SDHC: 4 to 32 GB.
SDXC: 32 GB up to 2TB.
Just as the calling card market needs more capacity, improved the standard for creating higher capacity cards. Does the problem? that electronic devices only read the standard for which they were created, the good thing is that there is backward compatibility, meaning that a team that can work with SDHC, so does for SD, but can not for the SDXC because it is more modern, therefore a SDXC can work with 3 standard, and that was the first SD can only work only with these cards. Improvements
Sometimes you will read SD and CF "Ultra" Extreme "followed by numbers. Well if we talk about the Ultra are like the above, but cards that have a class number, ensure a higher speed. Extreme
But beyond not only ensure faster, with physical improvements, better materials, for conditions "extreme" as the name. Cards are manufactured to withstand extreme temperatures of minus 25 degrees to 85 degrees of temperature (depending on model), shock and dust. Words are cards for professionals working in conditions outside of study, travel, harsh climates will be exposed to many situations that would not hold a regular card.
What do I need?
If you use a compact camera , ie a normal camera pictures with a regular card you better, if your camera is new must support (look in manual or look on the camera logo) SDHC standard, and as you will take photos holding 1 or 2 MB as you will need an SDHC 4 or 8 GB, what kind? You better any speed even 2.
reflex camera, here you see the speed, not only is class 6 or 10, but are enhanced and they tell you that at least 15, ideally 22MB / s, because if you take several pictures, the card will be fast enough to save the pictures, think that the reflex Bharatiya more market takes pictures of 15MB jpg + RAW, if you have a slower card 22MB, you can not do 5 pictures in rapid succession, in fact when you take 3 if the card is SLOW, class 4 for example, the camera will not let you take photos, because photos will be spending your RAM to the card, and if you take more photos will be erased from memory and therefore lose without being copied to the card (surely more than one has passed and said where are these pictures taken?).
video camera. Well, the HD world is coming and with it the FULL HD, here we can not have a crappy card class 6, here we have to buy a card with better speed, which is less than 15MB / s, otherwise we will see videos badly recorded, with stoppages, error when trying to open them, etc. It is for this reason that many cameras incorporate hard disk, so that the novice does not record videos with slow memory cards and then say, "go fuck camera," speak ill of the brand and sales down, but if you understand and see two houses with a difference of 200 euros and no hard disk and the other not, and what else being equal, because if do not want to drop both, Spend your 70 euros on a 16GB card which lets you record about 2 hours , and have more than enough if you are someone who uses only one party, met, baptism, unless you are of those who can swallow more than 2 hours these things.
