Uneven Map

This card (Transcend 8 GB Class 10) is very uneven in its performance:
- The video backup sometimes fails with a message "Insufficient card speed" (APN Panasonic TZ5)
- Some pictures are taken forever to be completely recorded on the map
And sometimes everything is fine (PC benchmarks also work well) ...

When transferring data to a PC, sometimes it's fast, and sometimes the transfer hangs for several tens of seconds ...

In short, I would put out a score of 2.5 / 5
I consider this card as a cheap backup card for when my main card (Class 4 Lexar "only") is full, because it really works more regularly (no failure in video recording: this is a fatal defect of Transcend )

Note: The packaging of my card is yellow (Model "Ultimate Class 10") and not black gradient as the current illustration.

*** Update 13/11/2011 *** comment
Less than a year after the first use of the card, it has become illegible by the camera, and in the midst of a journey.
Using software, I have been able to recover some of the photos taken (the card is no longer directly readable on PC), but more than a hundred pictures of my trip has disappeared.
The card is now unusable (anyway, after this mishap, I would not take the risk of losing still pictures with it)

==> Update Note: I changed from 2 to 1.
I do not rachèterais this brand (my other cards, Lexar and Sandisk, continue to give me satisfaction)
