    Hey everyone, just wondering if anyone notices any difference in game play/video playback when using a Class 2 SDHC memory card compared to a Class 4+ SDHC Memory card. Like lag for example.
    Thanks.

    Also, does anyone notice any difference in playback between using a 8GB sdhc and a 16GB sdhc with the same class?

    Nope, but some games such as calsavenia are a bitch to run; on low class cards.

    Is that for games AND videos?

    And thanks for the feedback. Some more would be appreciated xD

    I just ordered the DSTwo and I was seeing if the price range between Class 2 and 4 is worth it.

    I have 2 dstwo
    one is for me, I'm using the 8gb class 6 for RPG games only
    my kid is using the other DSTWO with the 16gb class 2, and it's full of NDS games, DPG movies, sega genesis emulator/games, GBA games, etc.
    they both run fine, the class 6 will always be better, but the DSTWO does a pretty good job of running slow memory cards..so I didn't see much of a difference

    the 16gb class 2 sandisk, I bought it from amazon for about $29
    and the 8gb class 6 sandisk, I also bought it from amazon for about $20


    I'll probably buy another 16gb class 2 for my RPG games

    I have 2 SDHCs, one is a class 4 4gb and the other is a class 2 8gb. I usually use the 8gb on my Acekard 2i, and haven't had any kind of lag in game or video. I use the 4gb on my TTDS, but decided to use my 8gb on the TTDS and really, it took like 2 or 3 minutes to load a game, but after the game starts there's no lag.

    In my DSTWO none of them have lag, only the Rune Factory 2 game has lag when so many sprites are in the same map, but that's normal.

    Alright, Thanks! I Just ordered an 8GB and 16GB Class 2 memory card xD If what everyone says is true, I won't have any problems with lag.

    I couldn't find anything other than a class 2, as I don't have any means of shopping online, but I have yet to have a problem in the months that I've been using it.

    It's not the class of the card that matters in this case. It's the card's random access speed (or rate) that matters. Classes are for their max transfer speed. NOT their random access speed.

    Then are you saying that all memory cards have the same random access speed?
    And I thought the class represented the Minimum transfer speed.

    It is Minimum, assuming your machine can handle it.

    Also I would think the DSTwo's in built Processor would help with the Speed issues of Class 2's.
    Personally I'da got a Class 6 as I hate waiting for files to transfer [​IMG]

    Oh and Class 6 is soooo much faster than Class 4 when saving games [​IMG]

    =P Alright thanks. The built in processor should help. And the save time on Class 4 is like 1-5 seconds depending on the game. (RTS is usually 5 seconds)

    I was thinking of Dragon Quest 9 and HG/SS in particular.

    Different brand memory cards have ALL different speeds. The "class" represents a guaranteed sustained write speed to the SD; Class 2 means a sustained write speed of 2MB per second, Class 4 is 4MB...and so on.

    Read speed is not rated, but is ALWAYS faster than the write speed. For instance, my Sandisk Class 2 16gig writes at 3.8megs (just missing a class 4 rating), but reads at 18megs per second.

    Random Access Speed is the SD's response time to any request made to it. The closer you can get to an "instant" response, the better. The problem is, it's usually not an advertised specification. So it's tough to determine what you will get when choosing an SD card to buy. This where where the brand-name SD cards usually shine. For instance, a Sandisk SD card will almost always have quick response time, regardless of its Class rating. There are other SD brands that are good...Toshiba is one, but I generally just stick to Sandisk these days, so I don't really know what-all SD brands are considered good anymore. Maybe someone else can help with that.

    Random Access Speed seems to only be important to "some" DS flashcarts. Otherwise, for other devices such as cell phones, mp3 players, cameras, etc. it's not a vital specification for the device to work. That's probably why most companies never bother to mention the response time specification.

    Most newer flashcarts have workarounds in place to fix problems between slow SD cards and demanding games. It's generally not a problem anymore....unless you have a REALLY crappy (and/or failing/defective) SD card.....or a really old flashcart that isn't "officially" supported anymore.

    Alright thanks! Just one more question. Would Kingston and Sandisk be on par with eachother in terms of Random Access Speed?
