    I'd like to start collecting MicroSD card benchmarks. If you have bought a MicroSD card for use in your Captivate, please help out.

    To test:

    Install the following:
    SD Card Speed Tester - Android app on AppBrain

    Run it several times to make sure you don't get a fluke low number (like from momentary activity). If your phone is idle, you should get consistent results.

    Then, please post to this thread with the following:

    Card brand/model
    Capacity
    "Class" rating
    Write speed (MB/s)
    Read speed (MB/s)

    Although it's not made obvious, the author has updated this app so that on Galaxy S phones it appends sd/ to the test path in order to test the external card (if present).

    Results will be consolidated onto CapFAQ.com

    I never formatted this card on the Captivate. Took it out of my blackberry and put it in the new phone.

    Do I need to reformat it on the Captivate?

    Just pop out the card and look. It should say right on the card.

    Unfortunately any data without a "class" rating is not of use and won't be tabulated.

    I tested two cards. My 8GB is in use, full of data, and I just unwrapped my 16GB. Used the default buffer of 1MB. After seeing the results, I'm a bit concerned about the read speeds. Looks like more people are getting 13+ even with Class 4 cards, where I'm maxing out at 13 with the Class 10 and not even getting close with the Class 4.

    Kingston SDC 2GB (bought ~2 years ago on Woot for $5)
    I never paid attention to class, and it isn't marked on the card.
    The tests says it may be class 6.

    I ran the test thee times, results were identical-

    Write 7
    Read 9

    Ebay, Seller from New York I trusted from previous transaction, he must have been feeling out the market because he has since pulled the 'buy it now' auction, here is one of his completed listings TinyURL.com - shorten that long URL into a tiny URL he also threw in a USB adapter along with the SD card reader. If he still had them available I would recommend it to my mom if that means anything to you. As I am sure you know, there are lots of fakes out there, but that doesn't mean they all are. I have been researching for a while hoping to find the promised Samsung Class6 MicroSd card but I just could wait anymore. Didn't want to buy 16 when for just a bit more I could get 32...

    On a completely different note and something you might want to consider in your benchmarks, I upgraded to Cog 2.2 B7 last night using the "From Eclair 2.1" steps found here TinyURL.com - shorten that long URL into a tiny URL and here are my numbers...

    Write 6-7-7-7
    Read 13-14-13-12

    I was quite pleasantly surprised as this is now reporting class 6 speed, I even bumped the buffer up to 5MB and still got the same results.

    I upgraded from 2.1 which had Unleash the beast v0.2 and RyanOCLF. Backed up my apps to my new card with TiBU, restore went perfectly.

    Patriot 16gb Class 6
    29.99 at Frys with SD adapter

    7/15, 7/15, 7/15

    I have a fistfull of movies on it and they playback very smoothly. Media scanning time isnt too shabby either, considering I have about 10 gigs of music on the internal and 12 gigs of movies on the external. Price for phone: 149.99, price for card $30. total, less than 200 for a 32gb phone. Price of 32gb Ip4 $300. Cant complain about that at least!

    Sandisk 8gb, class 2, tested 4 times (I guess something was running on the 2nd test), all 4 test were with a 1MB buffer

    Write: 6MB/s - 2MB/s - 8MB/s - 6MB/s
    Read 13MB/s - 12MB/s - 15MB/s - 13MB/s

    The app thinks I have a class 6 card

    Yeah, that's not gonna work for me. I've using the leaked Froyo, and even emulating other markets, I can't see it on the market. Fast Install on AppBrain also isn't working for me.

    So please, if you wish to help me, send me the APK, as I requested.
