quote=weebit]Yesterday evening I was shopping for a memory card. The one I have is only a 8gb and I wanted a 32gb card so I would not have to worry about space. In two months I am going on a trip and hope to take lots of pictures.
You usually can't go wrong with Lexar Cards. I have several of these cards and have never had a problem with them.
Imagine my surprise when I went on the web looking for them and found out memory cards have different classes.
I found this info below online and for the life of me I can't find that link today to share with you guys. Be sure after the info below to read the last entry because it is a eye opener.
-----------
Class ratings represent the minimum write speed for a memory card. So a memory card with a Class 6 rating will have a minimum write speed of 6 megabytes per second. Canon requires a Class 6 card or higher in order to record and playback HD video with the T2i.
The class six is the minimum and so it can have problems specially with video jpgs and raw pictures all on one card at the same time. So the class has to increase if you plan to do a mixture of types and save them to a memory card. So after some checking the least the card is to be a 6 for just jpgs and a 10 if you want video and jpgs on the card. Most of the ones on walmart website on sale are below a six there is only one memory card I found on sale and it's a class 6. Oh and btw with the memory cards ALL memory cards have to be a six or above for video. Including yours. If you use less than a class six the video wont continue to record, refuse to record etc. In other words it does as yours does and only records for two minutes or less and quits. It does this because video is writing at a pace of so many frames per second and the memory card can not keep up if it is below the six. OH and be careful of off brand memory cards some fool you by putting a number higher than six on their card but the card is not displaying a class number it is only part of the name of the card. So i did some searching and two cards get mentioned that is sandisk extream, Lexar Professional, and a few others. But these are the cheapest in their genre.
Oh and even JPGs have their non perks of six or less. If you use burst to take pics or rapid taking of pictures like in sports mode then you need a class ten because most digital cameras take pictures at three or four pics in one to three seconds.
Lexar Professional (133x or higher) or a SanDisk Extreme (30MB/s or higher).
Another thing the lower the space of a memory card under 16gb the higher the chance the memory card is a class six or under.

Apparently a few companies want to cash in on memory cards. They see the cash flowing and thinking many people wont pay attention to the stats, and only check that it works with their camera. Canon cameras need a class six or better in order to get pics video etc. So I went looking for a card after learning this above info and to my surprise I found cards labeled to look like they were class six or better but they were not class six they were class four. You see some companies not only put a number on their cards they also label with certain colors for each class. Walmart had several memory cards not labeled correctly. None of their on sale off brand cards were what they claimed to be as far as I could tell. Price was a give away. But the reviews told the whole story. Many people reviewing the cards stated the cards either did not work, or the cards would not record video. Or they could not use the rapid picture taking setting their camera could not keep up. Some even said their new card ended up corrupted and was not able to transfer to their computer.
Apparently too your camera will tell you what class your memory card is you have installed. But I don't know where this is on my canon T2i
This is all I have and sorry I can't tell you the name of the fake brand. I believe it started with a "T" and the card was either blue or purple. But I ended up getting a Lexar Professional 400x 32 GB SDHC card. Do any of you have your favorites? Honestly it took me hours last night to find a card because I am not well versed in the brands. I was sweating plus worried I will end up with a card that was not any good, or not labeled right.
