    Anybody know if the speeds a class 10 micro sdhc card affords are taken advantage of in the DX i/o system? I.e., will my music and pictures load faster?

    TIA,

    Don't do it. Get a class 4 at the highest.

    Elaborate please? Are the problems with the phone or the cards on the market?

    Random performance on class 10 cards is too low for this type of use. Ask me how I know ;)

    I'd like a bit more in-depth of a technical explanation than that :/

    Yes, please elaborate!

    And what type of use exactly are you talking about? Does the droid X do a lot of random read / write action? I thought these cards were just for storage.

    Just don't get a class 10 card. It will eventually lock your phone up.

    Or do - I don't care. But you've been warned.

    Agreed. This was discussed last week.

    Mind linking to that thread then? I've searched all over this forum and others looking for info on which sdhc cards work best with a droid x and all I can find are people saying don't get this or that. No mention of how exactly they came to that conclusion. I wouldn't care if there were some kind of majority consensus about good cards that do work but there isn't.

    So far the Patriot 32gb c10 seems to be the only guaranteed failure.

    No one has apparently tried the Lexar 32gb c10.

    Has anyone tried lower capacity c10 cards with a droid x?

    Anyone tried any c6 cards at all in an x? If so which ones? Cause I haven't heard a single report.

    I think Sandisk makes a 32gb c4. Is that a good choice? Anyone tried it?

    Best I've got now is this guy who says c4 is best based on personal experience with who knows what. I don't mean to say you're wrong. Only that I'd like the full explanation of your experience. If you've typed it somewhere else please just kindly post a link cause I can't find it.

    I can tell you from experience that not all class 10 SDHC cards are created equal.

    From Wikipedia:
    I purchased a Transcend class 10 SDHC card for HD video recording in my Canon camcorder. The camcorder manual states that minimum speed for HD recording is Calss 4, however the Transcend card that I bought did not work. I returned it and replaced it with a Kensington Class 10 of the same capacity and all is well.

    I'm not sure how this all may or may not apply to the DX.

    Thank you for your reply MNTNBKR. This is exactly why we need more information on the subject. It seems entirely inadequate to say that all cards of a particular size, or class do not work in the droid X without some further technical explanation of why that is. An explanation as yet not given, anywhere, that I can find.

    Anyone try the Lexar 32gb C10?

    It doesn't apply to phones. A camcorder acceses one file at a time. Class 10 cards are great for this, even though high sequential throughput comes at the cost of random throughput, and indeed this makes sense as recording resolutions have increased, and random performance is inconsequential in this usage scenario.

    For a phone, the problem is with operations such as cataloging large music libraries. The optimizations for sequential throughput make random operations like this extremely slow. So slow in fact, the phone will become unresponsive. Now, if you plan on only putting a small number of very large files on the card, a class 10 would be fine, but that is far from the typical usage scenario for an sd card in a phone.

    Clear?

    And if you need an analogy:

    Class 10 is a drag car while Class 4 is a road racer.

    Class 10 can run in a straight line extremely fast, just don't ask it to make a turn - where turning is akin to accessing another file.

    OK Fantastic. Thank you for that explanation. That does help.

    And I assume that a C4 is an advantage over a C2 only as a matter of balancing the advantage of fast sequential with the loss in random access? Would that be correct?

    Further, would you say the Sandisk 32gb C4 is an optimal card for the Droid X?
