    I picked up one of the new 32gb Sandisk cards from Verizon for $75 this week. I thought I would post up a speed comparison since many people seem concerned that it's only a class 2 card. I performed a full format on the cards (except the brand new 32gb which I quick formatted) to make sure they didn't have any data on them prior to testing them with Crystal Disk Mark.

    The net of it is that the 32gb class 2 card is either almost as fast or significantly faster (depending on the test) than the 16gb class 4.
    It seems to be exceptional at doing non-sequential writes in particular. I actually ran it several times just to be sure it wasn't some kind of fluke. All of the cards performed well beyond their stated class (especially the class 2 cards). Any of these cards are more than capable of keeping up with anything that the Droid X (or any other smartphone) can throw at it.

    For reference purposes, the Droid X records 720p at around 23 mbps or less than 3 MB/s per boygeniusreport.com.

    EDIT: I took a few videos myself the other day at 720p, and my videos all came in at just under 1 MB/s. I'm not sure what explains the difference between my own files and boygenius, but either way, they're both well under the capabilities of any of these cards.

    16GB Class 4 (came with the Droid X)

    Great post OP!

    I also purchased the 32GB microsd card (couldn't pass up the $75 price). My tests also confirmed that the 32GB was just as fast if not faster than the included 16GB; note that my droid came with a class 2 SanDisk instead of a class 4 Japan-sourced.

    Testing done on an XP-32 box with H2testw v1.4

    16gb Sandisk class 2 (came with Droid X)
    Writing speed: 3.85 MByte/s
    Reading speed: 13.2 MByte/s

    32gb Sandisk class 2
    Writing speed: 5.37 MByte/s
    Reading speed: 13.5 MByte/s

    8gb Sandisk class 4 (for comparison)
    Writing speed: 4.08 MByte/s
    Reading speed: 18.0 MByte/s

    Most people see class 2 and just go nuts and seem to forget that is a minimum speed. And if Sandisk does not feel like testing them they just slap a 2 on them and go along their way. Even if they know full well that the card is faster.

    Where are you getting SanDisk 32 GB for $100?

    I am checking Amazon and they have it for $130 through resell: Komputerbay.

    Has anyone any experience with Komputerbay?
