here is a write up i found about sony cards:
Memory Stick:
(Measures: 50.0 × 21.5 × 2.8 mm)
MS Memory Stick is a removable flash memory card format, launched by Sony in October 1998, and is also used in general to describe the whole family of Memory Sticks. This family includes the Memory Stick Pro, a revision that allows greater maximum storage capacity and faster file transfer speeds, and Memory Stick Duo, a small-form-factor version of the Memory Stick.
Memory Stick Duo:
(Measures:31.0 × 20.0 × 1.6 mm)
The Memory Stick Duo, which is slightly smaller than the competing Secure Digital format, was developed in response to Sony's need for a smaller flash memory card for pocket-sized digital cameras and cell phones, as well as Sony's PSP. Memory Stick Duos are available in all the same variants as their larger cousins (normal ones limited to 128 MB, larger Pro Sticks, with and without High Speed mode, with and without MagicGate support), and a simple adapter (often sold along with the Memory Stick Duo) allows a Duo to be used in any device that can accept their larger cousins.
Memory Stick Micro M2:
In a joint venture with SanDisk, Sony announced a new Memory Stick format on 30 September 2005. The new Memory Stick M2 ("micro") measures 15 × 12.5 × 1.2 mm and could theoretically have 32GB in the future. Maximum transfer speed is 160MB/s. It will come with an adaptor, much like the Duo Sticks, to ensure compatibility with current Pro devices.

The Nintendo R4 gaming cards are, quite simply, the best storage cartridges available in stores today. The card has been referred to with different names in different countries, i.e. Revolution for DS in English, YushenDS in Japanese and YDS in German.
Here is a brief history of the card as well as its clones:
The Original R4
This Nintendo gaming card came into being in early 2007 and was engineered by a team of engineers that proudly called themselves "Team R4". The original R4, unlike its successor, the R4v2, had a push lock system for placing a micro SD card inside it.
The mechanism came with a set of problems. The malfunctioning spring rarely but did cause the micro SD card to break inside the card slot.
Team R4 realised this and made relevant changes to the card and launched a new version under the name of R4v2.
The R4v2
Also called the Revolution for DS, version 2, the card replaced the original R4 some where around late 2007. The new version came without the hassles of the spring mechanism. Instead, it came with a slot inside its back. It enabled the user to manually push the micro SD card inside the cartridge.
With the new mechanism, people were worried that the micro R4 Cards may dislodge itself from the cartridge, while game play on the go. The r4 cards were tested for this speculation as well and the results came out to be just fine.
R4 Clones
A number of poor quality clones of the R4 card are swarming the market today. N5, ND1, E7, MARS, U2DS and Nplayer are some of them. Well, these still sound a bit "branded"! We came across a number of others such as R4 DS Upgrade II, R4 Advanced, R4 Deluxe, R4 SDHC and R4 Pro.
All these cards also make use of micro SD cards for storage and include auto-DLDI patching, Action replay cheats and can also render support for Nintendo Wi-fi.
Some Other Specifications
Unlike many new cards in its category, the R4 and all its subsequent versions are incapable of reading SDHC cards. You will be interested in knowing that some recent developments have suggested that a number of SDHC cards are highly prone to failure and malfunctioning. Only one clone by the name of R4 SDHC is know to be reliable as it hasn't shown any kind of mechanical or software problems.
The latest entrant from the labs of Revolution, the R4DS is the best of them all but with so many clones and bad quality remakes, it's becoming increasingly difficult to find a genuine R4DS.
Some other equally good cards in the market are Acekard 2, Edge and M3 real. They support SDHC technology as well and come with a host of added features.
