    I got almost 6MB/s write speed with the stock SDHC card (4GB capacity) that came with the N1. I replaced the stock card with a 8GB class 6 card I had flying around.

    To my surprise, the class 6 card isn't faster! Write speed is still slightly below 6MB/s.

    The point is that I eventually want to upgrade to a 16GB. But if the class makes no noticeable difference on the N1, I might as well get a "slower" class 2 card. Thoughts?

    This is something I've been hearing with the N1 not needing a class 6 card but I'm still waiting to confirm.

    there is nothing the N1 can do that will require anything faster than a class 2. hence anything above a class 2 will have zero impact on your performance.

    It makes a difference when you're transferring data to and from your card. If you listen/watch lots of podcasts and you're transferring GB's back and forth regularly it's worth the extra speed IMO, but you do have a point.

    Class 6 means min 6MB/s, it sounds like your class 6 card is slightly under par and your stock card is pretty good. If you bought a class 6 16GB card you shouldn't expect it to be any faster than 6MB/s. C6 16GB cards are too expensive at the moment (in the UK at least).

    I like to use my N1 for Sneakernet, the highest write speed I have reached on the class 6 card on my N1 is 3.9MB/s this is the card that came with my HTC Magic.
    Class 6 cards are guaranteed to have atleast a 6MB/s write speed. It is either a problem with my computer or a problem with the Nexus One and I am suspecting the Nexus One.

    I get 4.6mb with the card that came with it, and a unrated 16GB that i bought.

    I don't think its really worth buying anything faster for the N1. Its different on cameras etc where it affects the picture speed.

    I take you're point about transfering big files but I really think a small file at 4mb/s vs 6mb/s isnt going to make any difference at all, and huge file will still take many minutes - which means you have to go and do something else while its transfering.

    I'll save my money for when 32mb's come out :)

    thanks all. looks like the consensus is class 2 will do. the other question, of course, is whether to wait for 32gb. (but that has been discussed to death in other threads...)

    32gb looks like its going to be pretty expensive when it comes out. I heard a story about some company mass producing 16gb's and their price is about to crash. I forget where now tho but it was a reputable news source. I still think it'll be months before they drop in price.

    We can probably expect 32gb's to be no less than twice the price of 16gb's today when they first arrive :(

    hello guys, new on here and thought I would share what I have found.
    I have just got my self a Desire HD and it came with a 8GB class 4 but I had a 16GB class 2 already, oh and I also had a Nokia 8GB class 6 sitting about so tested all 3 and this is what I got:

    Sandisk 16GB Class 2
    Writing speed: 8.97 MByte/s
    Reading speed: 17.2 MByte/s

    Sandisk 8GB Class 4
    Writing speed: 5.49 MByte/s
    Reading speed: 11.1 MByte/s

    Nokia 8GB Class 6
    Writing speed: 4.84 MByte/s
    Reading speed: 15.5 MByte/s

    Now I was just about to give away my class 2 16GB Now Im glad I did'nt
    Its confused me more then ever but from the test I just done, it shows this class business dont seem to mean alot, Unless Im missing somthing??
