Rating: - A matter of luck?
I bought several of this card, this time I got 2 and 1 did not work, some time it accept data, some time it doesn't. A reliability issue...or just a bad luck?

Generally this brand is ok for the price but if the quality is dropping, is better to put more money and get something that work 100% of the time.

Rating: - Very Fast
A simple benchmark test using the HDTune benchmark program indicates an impressive 21Mbps READ rate using a USB 2.0 card reader. The card may be faster but that's the max speed supported by the USB 2.0 port on my computer. I also tested WRITE speed using a 100MB data file and it took 4.5 seconds to copy which is also very fast.

My previous card (which was expensive at the time) only runs at 4Mbps.

According to the Transcend specs it can operate up to 266x. The x refers back to the data rate of a traditional 2 channel audio CD running at 1x speed which works out to be 150Kbps if you do the math.

So if their specs are accurate it can go up to 150Kbps x 266 = 39.9Mbps. I'll have to get a card reader with a IEEE1394/Firewire interface to be able test a card that fast.

I also observed that it's detected as an IDE device on compatible systems, not just a flash drive. This card may have some interesting uses in the future.
