OK... I thought I understood SD "Class" speeds, and have often told people to go for a Class 6 or above card, and also pointed people to the Wikipaedia article and speed table here.

So what on earth is this, which arrived in my inbox today, from a respected company?

I would have assumed the "Class 1" in the text was just a typo, but there's a logo for it on the label too. It's at a premium price and it says it's especially for fast full-motion video recording. [/img]

Looks like it's a new class - UHS and needs a device which is compatible with it, otherwise it may even be slower than a class 10 SDHC.

Well, that's what it says here - see latest post 5 days ago by hogwild.

UHS-1 technology is an all-new way to improve speeds on SDHC cards. That's good news...

.... but to "avoid confusion" they've decided to use a numbering system for class-rating that's totally different from normal SDHC. Brilliant! Rolling Eyes

So from what I've read on those links, there is absolutely no point in using one of these new cards in a TomTom. In fact it might actually be slightly slower than a Class 10.
