Wrong SD Card class....

While I was at Costco, I saw they had a 32GB, Class 10, Micro SDHC card for a cheap, so I grabbed one. I got my trunk full of stuff home, and went to open the package. It says Class 1, or 30 mbps speed.

My Maxx has the original 16gb class 4 from my OG Droid in it now, and works fine. Before I take this back, does anyone know if this will work ok, or do I need to get a refund and get at LEAST a class 4 to replace what I have?

I just want some more storage. There is nothing wrong with my current card as of now.
 
There are different classes of SD cards. Class 1 is supposed to be the best. Never heard of a class 4 but class 3 is the most common and seen on most store shelves. At Fry's electronics for example, my father in law was looking for a new SD card one time and well he noticed they varied a lot in price so he looked into it while he was there and well let's say a class 3 32gig cost 30-40 bucks. Pretty good right? Well add 30 bucks to that price for a class 2. And then when you jump to class 1 you are looking at triple digit cost.

The reason for this is that each class is made a little better. Ever had an SD card go corrupt on you? I have, and I lost A LOT of pictures and videos from more than just a year of taking them. I'm still tempted to send it out to a company to have them pull it all off. Anyways, if you did actually get a class 1 SD card for cheap then you scored big! I have done my research after my father in law told me this and find it to be true. Good luck with the card and I hope I have been able to help.

Sorry, but you need to get your facts straight. Below is a copy from this website

Secure Digital - Wikipedia, the free encyclopedia

Speed Class Rating

The SD Association defines standard speed classes indicating minimum performance to record video. Both read and write speeds must exceed the specified value. These are defined in terms of suitability for different applications:
  • Class 2 for SD video recording
  • Class 4 and 6 for high-definition video (HD) to Full HD video recording,
  • Class 10 for Full HD video recording and consecutive recording of HD stills
  • UHS Speed Class 1 for real-time broadcasts and large HD video files
The specification defines these classes in terms of performance curves that translate into the following minimum read-write performance levels on an empty card:

ClassMinimum performance
Class 22 MB/sec
Class 44 MB/sec
Class 66 MB/sec
Class 1010 MB/sec
 
I'll be you can guess why I'm here. ;)

I deleted a few threads that were getting too personal.

Here we attack issues, not each other. Please try to remember that when you are discussing differences of opinion.

To the op: There have been counterfeit class 10 MicroSD cards floating around the channel for some time. You can usually identify them by inconsistent or non-standard markings. They will perform horribly, if they work at all.
 
So, I wanted to apologize for my words earlier in this thread. I was harsh and out of line with my wording. I am not one that normally lays out personal attacks honestly. I just don't believe in using an open source website that allows everyone and anyone to put what they want on it as credible information.

I do have to say that I have never heard of a class 10 sd card. I never knew of any sd card class until recently. Perhaps different markets and areas of the US make available different classes?
 
A little off topic but the idea behind Wikipedia is similar to the open source paradigm for software. The more eyes on the code (or information), the more likely errors and bugs are caught. While I agree the potential for misinformation is there, if any blatant errors get posted, they get shouted down very quickly.

Now, don't get me wrong. I do not believe in "truth by consensus" but I've found Wikipedia to be general accurate and always informative.

I don't think classifications of SD cards or the nomenclature varies by region, at least within the continental US. However, it's not required to imprint the class on the card. There are many brand name cards that are blank ... especially those that come as OEM cards in a device like a phone or tablet. We won't even begin to get into the Chinese market. :rolleyes:
 
Your best bet is to go with a well known brand from a well trusted retailer.
Picked up this Sandisk 32gb class 10 micro sd on Amazon a few months ago. Caught it on sale for $28. Well below the retail price. Couldn't be more happy with it. For that low of a price I couldn't pass it up.
