    !!!!!! Warning!!!!! Warning!!!!!
    To all of those thinking of buying this 32gb sd card hold your wallets.. People this is a class 2 card. Remember this phone is a very fast & powerfull machine with a stunning 8mp camera and 720p video.. I dought if you want to put a very,very,very slow processing class 2 memory card in it. The best route is to purchase a 16gb class 6 sd card for 79.99 and really enjoy the speed of taking pictures and recording video.. Trust the 32gb their trying to sell u for $100 bucks is no match for a 16gb class 6 for $79.99.
    If u are confused by this post just google class 2 vs class 6 micro sd memory cards.. The rest is history....

    you're not going to see the speed issue in taking video or pictures nearly as much as transfering them. Don't do what I did though, and buy a fake card on ebay

    I'm glad someone came out and said what speed the 32GB card's speed actually was. I have some Class 6 regular-SD cards and they are nothing short of stunning, like the phone.

    Of course its a class 2 card, did you really expect VZW to offer a deep discount on a speedy class 6 card?

    Im looking for space not transfer speeds, but thats just me. If I were a photographer or something like that class might matter.

    Are the transfer speeds really that different from the class 2 to the class 6? I don't know much about these SD cards so any information would be helpful. What would be the difference in speeds?

    The class determines the minimum write speed the card must meet. Some cards might specify a class 2, but perform at speeds much higher. Mostly important when recording HD video.

    Bingo. It's write speed that makes the difference. I am photographer and need fast-writing cards in my DSLRs. I hadn't thought about the HD video recording with the Droid X. I bought the 32gb card for music storage needs. I'll have to test the card for HD recording. I suspect it's more of an issue when taking long videos.

    Some Perspective...

    For Video
    ------------
    Class 2 = 16Mbits/sec
    Class 4 = 32Mbits/sec
    Class 6 = 48Mbits/sec
    Class 10 = 80Mbits/sec
    Secure Digital - Wikipedia, the free encyclopedia

    DVD Playback = ~10 Mbits/sec
    HDTV Broadcast limit = 19.3 Mbits/sec
    Blue Ray Playback = 36-48 Mbits/sec
    Blue Ray Spec limit = 54 Mbits/s
    Blu-ray and HD-DVD - What You Need To Know About The Blu-Ray and HD-DVD High Definition DVD Formats
    ---------------

    For Transfer speeds
    ------------
    Class 2 ~= 13x CD-Rom Rating system
    Class 4 ~= 26x
    Class 6 ~= 40x
    Class 10 ~= 66x

    MegaBit to GigaByte per second = /8000
    Seconds to Minute = *60

    Class 2 = 0.12 GB/min transfer speed ~ 8 minutes per GB
    Class 4 = 0.24 GB/min ~ 4 min per GB
    Class 6 = 0.36 GB/min ~ 3 Min per GB
    Class 10 = 1.2 GB/min

    Class 2 ~= 128 Minutes to fill 16GB Card or 4 hours for 32GB
    Class 4 ~= 64 Minutes to fill 16GB or 2 hours for 32GB
    Class 6 ~= 48 Minutes for 16GB or 1.5 hours for 32GB
    Class 10 ~= 13 minutes for 16GB or 27 minutes for 32GB
    -------------------

    You should ask yourself... How will I use this card... and how often will I transfer HUGE amounts of data, and will I wipe and refill my music collection on a somewhat regular basis.

    ------------------

    Then again... 32GB is just plain awesome in that small of a form factor. I for one will be happy with a class 2 card. Don't forget the 'Class' markings are min spec. Most things are not min spec but somewhat greater in performance.

    The Sandisk 32 GB card from Verizon for $100 is a great deal, and is running fine on my X. Loaded 0ver 2000 songs with missing sync from a Mac in about 20 min. Camera and video camcorder are responsive and fine ! You'll never notice a "class " difference in day to day once large amounts of files are loaded.

    I ordered the 32gb card from Verizon,so that I can actually compare its performance with the class 4 16gb that came with it. I can always return it if it actually degrades performance, rather than depend on assumptions that it will.

    You most likely will notice a difference in doing hi def video recording. All hi def video cameras recommend only class 6 for that use.

    The 16GB card that comes with the Droid X is a class 4 (at least mine is). The specs say the Droid X can handle Class 6 cards. The difference in transfer speed between a clsas 2 and a class 6 is probably about 2-3 times faster - a noticable difference.

    That's likely for an SD card, not a micro SDHC card.

    I just received and installed my 32gb card today. To compare performance, I made short video clips with the original class 4/16gb card and with the new 32gb/class 2 card, that consist of panning with dense subject matter, which to me has been most likely to display when frame dropouts occur due to lagging processing. There may be other ways to test and compare that I haven't thought of yet, or lack the skills, knowledge, software, or equipment to perform but this is a first attempt, anyway.

    I really don't see any significant differences between them. They are both a bit jittery, partly because of me, and partly, I think because of the low frame rate of the DX, but I think they are pretty comparable.

    FWIW, the file size on my 18 second clip above was 17.9 MB, and of course it was recorded to the microSD card. I guess that would translate to about 1 MB/s, and 8-10 mb/s, which would be within the class 2 capability. I wouldn't try to record while simultaneously doing other data intensive activity to or from the same memory.
