Installation and Testing:

Use larger opening

Contacts up

Secured SD

If I have to explain how to install a SD media card into a SD media port, it's time to pull the power on the computer. Now, what I will explain is regarding the USB connection: you will have to pay attention to how the tab slides into the USB port. When looking at an USB port, you will notice a divider that is off center of the opening. One side will be larger than the other side. The USB tab on the OCZ SD Dual card will fit into the larger opening with the contacts facing toward the divider in the USB port.

For testing the Removable Storage /Flash Benchmark test from SiSoftware Sandra was used and the results are shown below.

Conclusion:

There isn't too much I really can say about SD flash media other than it's one of the most versatile media cards I have used so far. I personally have have CF, SD, and Micro SD cards in my collection, and I normally have to make sure I either have a card reader installed in my computer or have a portable card reader that I keep in my laptop bag. This sometimes can be a major inconvenience, especially when I just grab my DSLR and head out to take some pics.

With the OCZ SD Dual connection system, I no longer have to worry if I have my card reader with me or if the closest computer has the proper media slots. Instead, I just pop the top cover off and use a free USB port on the closest computer I can get a hold of. It definitely makes my life easier, and it can for you as well. I suggest picking up one of these bad boys as soon as you can. I would like to thank OCZ for sending out the Secure Digital Dual 1GB card for VH to review.
