I just got a samsung-a920 cell phone to play with and one of the most interesting aspects is the absolutely TINY TransFlash memory card that comes as part of the package. As you can see from the picture at the right this card is smaller than an American quarter. It comes with the SD adapter, also pictured. Now, this got me thinking. I had seen at least one USB card reader in the past. Are there more? Are they small? SO I set out to discover what is out there. What I was looking for were models that look like USB thumb drives. I have seen the multi-slots that are often large and clumsey (in my view). What I want is something small and easy to carry around. And something that’s going to work in nearly every computer.
All of the following drives use USB 1.1 or 2.0 and can be used on windows and Mac OS 9 or greater. They don’t all read every memory card, however. And some will need an adaptor for certain cards like the very very small TransFlash. These cards tend to come with their adaptors, which is good.
