Why do 32GB Class 10 SDHC cards vary so much in price between brands?

I'm comparing several 32GB Class 10 SDHC cards from different brands and seeing very large price differences, even though they all have the same capacity and speed class. What usually explains the higher price? Is it mainly brand name, or do more expensive cards tend to offer better reliability, durability, or real-world performance? For an amateur photographer, are cheaper cards usually fine, or are they more likely to fail sooner?

SDHC cards get a class rating (6, 8, 10) which denotes how fast the card can transfer data, higher class cards will transfer data faster and for that reason cost more money. However the 3 cards you've linked to are all class 10.
The other difference between them is quality, cheaper cards are more likely to fail sooner in my experience. I've had a search around and I can't find any studies done on this, maybe someone else can. I've personally had issue's with a Transcend branded card very early in its life and since then I've only bought Kingston cards (and have yet to have an issue). Others will likely recommend other brands.
It's my understanding that flash memory is actually produced in very few places by very few companies and that the majority of brands that you find on cards haven't actually produced the flash memory itself, they simply buy it from the places that do and put their own branding on it. I suspect that some of the cheaper brands will buy the lower quality samples from factories!
I won't tell you to buy the most expensive card but neither will I tell you to by the cheapest either, I'm afraid you have to decide how much you feel is a reasonable price and shop around.

Price differences between SDHC cards with the same capacity and class rating usually come down to more than just the Class 10 label. Class only indicates a minimum write-speed tier, so cards with the same class can still differ in real-world performance, durability, testing, and reliability.
Higher-priced cards may use better flash memory and controllers, and some premium product lines are tested more heavily for speed consistency and toughness. Brand reputation also affects pricing. Some manufacturers sell multiple tiers, where budget lines are cheaper and premium lines are marketed as faster or more durable.
Cheaper cards are often perceived as more likely to fail sooner, though the answers here are based mostly on user experience rather than hard studies. Also, many card brands do not manufacture all the flash themselves, so branding alone does not tell the whole story.
In practice, an amateur may not notice much difference if the card meets the camera’s needs, but reliability matters for everyone. A sensible approach is to buy from a reputable brand and avoid choosing solely on the lowest price.
