Very fast card – Transcend 16GB SDHC SD Mega Memory Card (Class 10 High Speed) Reviews

Pros:
It's fast. A quick benchmark with bonnie yielded around 18/16 MB/s R/W rate for contiguous transfers, which is the highest I've seen in an SD card.
Cons:
Nothing serious. Highly random access is much slower, naturally. A lot depends on the workload, of-course. Obviously the on-board flash controller wasn't optimized for random data access patterns.
Other:
I'm using this as system disk for a PandaBoard, and it works beautifully.
Bottomline:
In common use, such as a storage medium for still/video cameras, or media-players, this is probably as good as it gets. The price is pretty good, too.
On the other hand, if you want this card to serve as a hard-disk replacement with a lot of random I/O to smaller files, then this *might* not be optimal. I suspect there are other class 6 or maybe even class 4 cards that may be faster under certain random loads.
