Panasonic (RP-SD128BU1A) (128 MB) SD Card

Pros: Powerful, fast and can hold huge amounts of data.
Cons: None that I can think of.

I bought the SD card because I was going on a trip and needed a memory card for my digital camera. This worked out perfectly! Not only did I keep piling photos on to it, I also downloaded my trip details, phone book and more. This card really is so versatile--I was able to keep everything on this one single card! I also really like that it is super small and durable and can hold so much data. I know my friend bought another competing format product and she had problems with it not being compatible with her other stuff--I have not had any of those problems! I highly recommend this to anyone who is in the market for a SD memory card. I know they have one that is even bigger that has 512 MB and can hold up to 11 hours of audio! Pretty amazing stuff.
