Query: An excellent storage device

I bought it for my Minolta Dimage Z1 digital camera. The camera has high speed auto focusing and it works well with the SD chip. I wasn't sure about it at first, having read a lot about Sandisk's problems. Thought maybe it was just an OEM version of Sandisk. I was going to buy a Lexar or a Panasonic, but thought I give the Kingston a try. Had it for more than a month now with over a hundred pictures, it has performed perfectly. Also, 512MB will last forever. Never a need for more space. . Kingston has tranditionally done well in all their products. Kingston SDRAM memory chips have always been very reliable.
