Initially, this card was slow to accept data. I forced it to store 2.5GB of data through a USB Compact Flash adapter. When finished, I placed it into my device and it read fine without any problems. 5 stars, good enough for me.

When it came to putting more data on it later, it was even slower, but I don't have the actual data, but the speed drop was definately noticeable.

NOW this card won't work in anything I tested it with. I will let it sit for a month and give it another try, but for now I will go with a known name brand like SanDisk.

Works fine on my PC and is faster than my Transcend 120X. It lost a star because it skips more often than the Transcend on my Pioneer 6900UB car stereo.

Used the card a few times in Maine with no problems, but after shooting 500+ shots at a bike race, it stopped working. I lost a day's worth of shots. I'll never use an A-Data product again.

This card is too slow to be reasonably used for continuous-drive shooting on a large-sensor camera. However, on the Canon 5D Mark II, it can keep up with the HD video stream. Some supposedly "fast" cards apparently are only fast on the reading part, not on the writing part, and eventually cause the camera's video buffer to fill up and eventually lock up the camera. This card won't do that. It will hold a good amount of video for (relatively) little money.

It also works just fine, of course, for single-shot shooting.

I got two of these, and they both work great. I was able to upgrade my good buddy's ipod mini, as well as my own zen micro to 16 gb. It was alot cheaper than buying a new unit. Highly recommend.
