    So I got a Sandisk 8GB Class 4 MicroSDHC from DealExtreme when I got my SuperCard like last April and for some reason, SuperCard auto detects the read speed as a speed of 5. My friend's Kingston 8Gb Class 4 MicroSDHC on the other hand gets detected with a read speed of 25! Does this seem right? I've formatted the card numerous times, and I can't even get past the full format when using the Panasonic formatter. The card works, but I'm beginning to think that I got a fake.

    If I do have a slow card and it's the reason behind why my DS videos are out of sync, then I may purchase a new one. Can you guys recommend me a good, fast MicroSDHC card just in case I need a new one? Thanks!

    Can a slow SD card cause problems when playing DPG4 videos on Moonshell? DPG videos that were originally converted from AVI works fine, but if they're converted from RMVB format, the sound gradually gets faster than the video.

    as far as i know
    the read/write speed between kingston and sandisk is different
    some tempers say kingston got one of the better speed [​IMG]

    on the other hand, i am using sandisk class4 8GB and i never ever have any problem on my gaming experience

    the rest i can't answer since i hardly mess with videos

    Format using FULL [ERASE: OFF] option.

    Are your videos out of sync if you play them on your computer or just your DS? If it's out of sync on your computer then the problem is with your encoding.

    You can test your card's speed with this program that you run on your DS: http://gbatemp.net/index.php?download=1381

    I have a Class 2 Sandisk 8GB and these are the results. If your numbers are significantly higher (slower) than mine then there's something wrong.

    My videos are fine on the computer, but when I convert them to DPG using Xilisoft, then the sound gets out of sync. I have a thread over at the Homebrew section on this.

    @elixir. Thanks for the info. Will definitely keep that in mind.

    @zero. Did you get your Sandisk from DX too? I'll test my SD card with that program later tomorrow due to studying for exams and report back with the results. I'll also use HD Tune (or was it HD Tach) and see what it says.

    Edit: Didn't want to double post.

    @zero. I did the test. How do I see my results?

    No, I got mine from from eBay.

    I think both HDTune and HDTach will work. I use one called Flash Memory Toolkit which was designed for flash drives.

    @zero. I did the test on my DS. How do I see my results?

    As for the results from HD Tune after using the Panasonic Formatter.

    Does that seem right? There's nothing in the SD card yet. Oh and don't mind the CPU usage. I'm running F@H as seen in my sig.

    The results are displayed on your DS screen.

    Your read speeds are fine but your Access Time is high.

    Here's my Class 2 8GB Sandisk:

    For reference, here is a Class 6 Transcend 8GB:

    I suspect mine's a fake, thus the slower speeds, higher access time, and probably the cause of why RMVB to DPG videos converted with Xilisoft get out of sync.
