Which SD card should you choose?
Not all SD cards are created equal — there are different makes, speed classes, physical sizes, and capacities to consider. This can be daunting for a first-time buyer, so here are all the differences you need to keep in mind when making your decision.
Generic or Name brand
Most of these chips are made by the same silicon chip fabricator and assembled in China, Taiwan or South Korea and this is where most of the brands come from. So the chances that your generic and name brand are made in the same factory are high, however, the money you save by getting the generic may be lost if it fails and you have no service backup. It is better to get a name brand so that you have recourse if it does fail. You are likely to see very little difference in brands.
Samsung the single largest manufacturer of memory chips in the world and manufactures most of the memory module chips that go into SD cards. There are obviously other manufacturers, but in this arena Samsung is king.
There are four different speed classes — 10, 8, 4, and 2, with 10 being the fastest, and 2 the slowest. They are measured in MB/s or Megabytes per second.
Class 2 is fine for point and shoot cameras, where you will be shooting single images every now and then. I would not recommend a Class 2 SD card to anyone who has is serious about his or her photography. Classes 4 and 6 are fine for standard definition video recording and JPEG images coming out of most consumer DSLR or mirrorless cameras. If you plan on shooting full HD video or you only shoot on RAW, then a Class 10 card is what you should be looking at.
