Nintendo DS cartridges, as well as their newer counterparts the DSi cards that are compatible with the newer Nintendo DSi and DSi consoles, enable users to expand on their handheld console experience. Not only can they play games as before, but are able to perform a host of other activities including converting their Nintendo DS console into an MP3 player, movie viewer, or even a PDF and office document reader!
The R4 SDHC card was the first card ever to accept memory greater than 2GB. It could accept higher high capacity (HC) memory cards, hence the name R4 SDHC. It is now an established norm that cards accept high memory capacities, but the R4 SDHC was the card that started the trend. At the time, 8GB Micro-SDHC cards were just beginning to emerge on the market and the amount of users that flooded to the R4 SDHC to take advantage of this made it a real contender for the fastest selling DS card at the time, alongside the original R4v2 and the DSTT card. The only obvious downside to the R4 SDHC card was that because of the increased memory capacity, loading times on the card were approximately 6 to 8 seconds, much slower than the 2 to 3 seconds often seen on the R4v2 and the DSTT.
