does micro sd card class matter?
 

I was looking into buying a micro sd card for my N810, and I noticed while looking that there are a few different classes of them (1-6, I think). I was wondering if a certain class wouldn't work with the N810? If so, please tell me which ones to avoid. Thanks!

They all work. Higher class cards just do so faster, generally. Please see:

• Class 6 vs class 4 SDHC card - am I likely to notice any performance difference?
• Questions about MiniSD cards - class 4/6?

Would you say that a class 2 micro sd card would be too slow for "normal use" in an N810?

If "normal use" is holding an assortment of MP3, JPEG, PDF, and whatnot files you access now and again throughout the day, then yes, Class 2 should be fine. If "normal use" is booting off the card, then you're better off paying for Class 4 or better.

thanks! when I said normal use, I meant the first one (I didn't even know you could boot from the memory card!), So a class 2 sounds fine to me!

The class rating replaced the "x" speed rating (4x, 12x, 155x, etc.) of non SDHC cards, but is primarily used only for SDHC cards, which a 2GB card is not. Between several cameras, phones, and other electronic devices, I've bought quite a few SD and SDHC cards, and I've never yet to even see a Class 2 card and never seen a 2GB or less card with a Class rating instead of a "x" speed rating. The slowest I've seen is a Class 4, and those are usually dirt cheap (like US$6 for a 4GB Class 4 card). If you're paying more than that for a 2GB Class 2 card, you may want to look into getting something more for less money.

The Class or speed rating of SD/SDHC cards typically refers to write speed. The read speed is typically only limited by the hardware you are using it in. So if you're predominately reading data (playing MP3's, videos, etc.) with your SD cards, then it doesn't really pay to go for the faster classes/speeds, because the price will typically go up significantly with the better speed rating. It will take longer to initially copy the data to the card, but if you're patient and predominately read data of the card anyway, then it's probably better (especially financially) to just go with a Class 4 card.

Only time I've seen Class 2 is on cards that are the largest capacity cards that are currently available. The 16 GB microSD card I have is a class 2. There may be 16 GB Class 4's, but they are likely quite a lot more money than what I payed for my card.
