I recently needed to purchase a new memory card for pictures before this year's vacation. So I headed to WalMart thinking I was going to get another one of what I already have. I have a 128 MG SD Card, and it holds about 165 pictures on it when used in my 4 mega-pixel digital camera. Looking around I couldn't find one like it. The only SD Card I saw was the Lexar 1GB SD Card.
I picked up the box and started reading the back. WOW, it looks like this one holds way more pictures than my old one! It doesn't give the exact amount for a 4 mega-pixel camera, but I could tell it was going to hold a lot more. So I bought it! Brought it home and put it in my camera and it holds 760 pictures!!!!! Great news for me, I LOVE taking pictures!
It easily transfers pictures to my computer and works great! The box also says it will hold 243 songs on an MP3 player. I don't have an MP3 so I can't give any personal experience on that, but thought that information might be useful to someone.
Overall a great deal in my opinion!
