The OCZ Secure Digital Dual 1 GB is a really good SD-card that can also function as a USB2.0 memory card. What I really like about the card besides from the general performance is that you can access its data anywhere with every PC because of the USB2.0 capability. This is quite handy because you do not have to carry a card reader on you which is quite handy for a student like me.
One of the neat things about this card is the write performance, which is way better than most SD-cards. This means that you won't miss that second all important shot because your camera is still writing to the memory card. I have tested this with my 10 MP camera and there was actually a substantial reduction in write time over my A-DATA 1GB card.
Now the only thing that I disliked about the card is the access time which is way above that of my two A-DATA cards. This of course isn't that important unless you plan on using it as a Vista ReadyBoost memory.
