* The class 2: forget them, they are usually largely outdated models, therefore ageless stocks.
* The class 4: the bare minimum for today device debits read / write means. Ideal for smartphones and compact camera without HD video storage or transfer large files, go your way.
* The class 6: The flow rates are sufficient for 720p HD video and fast copies. But since the price drop of 10 class, this format bcp has more interest.
* The class 10: for now, the fastest and most suited to the demands of Full HD 1080 also ideal for any photographer using RAW format and modes "burst". Not forgetting eager to copy files.
THE NAMES:
* ULTRA: the basic range for a quality product
* EXTREME: excellent quality and constant rates
* EXTREME PRO: THE MUST for those who have the means and demanding
Remember tjrs a memory card does NOT displayed the number of gigabytes. Expect a "loss" of about 5 to 10% required to format the memory. USELESS so to complain to length of your wonderful comments 32GB SD only 29 ... is NORMAL (... but ask people to stop complaining in this country ...) :-(
Short. All I wanted to say is that the product is good ... ;-)
Edit the comment. 04/24/2014
Shortly after writing this text, needing to buy a card, I realize that the offers are very diverse and often damaged ... ...
Explanations:
Even on SANDISK, the endorsements included on the cards confusing. You can find
"Extreme" with identical flow rates at "ultra" or 30m / s .....! So vigilance!
Refer instead to advertised speeds and the pictures of the proposed product.
TO KNOW:
15 to 30 mb / s okay if you have a compact, YOU DO NOT VIDEOS full HD (1080) !!
45 to 80 mb / s: well, if you have a apn "expert", an SLR (for burst modes) and full HD video.
80 to 95 mb / s: the must, especially interréssant for very fast speeds copy files to a computer or data transfer.
So in summary for those who follow ....
An "ultra" 30mb / s class 10 is the bare minimum for most uses.
An "extreme" 95 mb / s class 10 for pros, demanding and impatient .....
CONCLUSION (provisional ...)
Considering the prices, remain on models "class10" and read many descriptions
Good luck,
(And interro. In a week ......)
EDIT ... to edit .... 06.10.2014. (You sent your interro.?) ......... :-(
Since the subject that you are passionate about and many of you reading this comment (thank you to you), turn to other things to know about these extraordinary pieces of plastic ....
- The SDHC and SDXC mentions. In the genre, it's Thomson and Thompson, as the standards SDHC (High Capacity) and SDXC (eXtended Capacity) primarily concern storage capacities. Indeed, the SDHC range from 4 GB to 32 GB. SDXC cards offer for their storage capacities ranging from 64 GB to 2 TB. For the latter, the MAJORITY devices dating from before 2008 will not be compatible!
NO CONNECTION WITH SPEED OR PERFORMANCE OF THE CARD !!!
- UHS 1. You see this statement on bcp cards is the "Ultra High Speed". Well, let's be clear and brief, it is as "whiter than white washing" .... The standard UHS 2 is on the market soon, just to convince you that you need to invest again if you not want to go for "has been" to your neighbors .....
In a general manner, do not buy high-performance cards if your device does not.
Let me explain. It's like putting a Ferrari engine in your Twingo! (It's more clear? ... Uh, not sure ...)
OK, migraine watching you, so we will discuss the theory of relativity data transfer rates again.
! NO, NO ..... Go not, you see, it's not too complicated .... ........: - [
EDIT LAST. 05/07/2014 ............ ...... all good things come to an end!
Yes, summer vacation, caps .... so many new adventures that require close this already very long comment :-) :-) :-)
But do not worry, I will not leave you without some summer homework ..........: - [: - [
QUESTIONS / ANSWERS:
- WHAT CARD FOR SMARTPHONE OR TABLET? (Touch, what!)
These machines are equipped so that a low internal memory SD bcp almost mandatory if you have any kind games apps, storing and downloading videos. In my opinion Prefer QUANTITY Go on pure PERFORMANCE card. So, a 32GB class 10 Just 1 uhs rather than 8GB Extreme Pro at the same price! In 80% of cases, you hardly notice the difference !!!
- WHAT CAMERA CARD?
Well, it depends on bcp things .... but simply put, RETURN SEE THE START OF THE TEXT :-) :-) :-)
- WHAT CAMERA VIDEO CARD FOR SINGLE OR "ACTION CAM" (like Go Pro and company)
Well then, you need heavy .... in quantity and quality. I think 32GB SDHC Extreme Pro or minimum 45mb / s, ideal 95MB / s. I know it's expensive, more reason to take care !!!
- WHAT CARD FOR GPS?
Ben, the cheapest you find enough well .....
- WHAT CARD FOR THE IRON?
Uh .... reread the instructions for the device .....?
Finally, remember that these cards CONSTANTLY like neither
HEAT, HUMIDITY's, DUST, FINGERS ON THE SHOCK CONTACTS and ...... !!!
Well, that's all I have to "menu" of the band EX dunces class :-)
For the rest, see the "card" :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) - ) :-)
A chao, good wind and good fuck OUT COVERED ..........................!
