400D CF card and UDMA?

[Trifid]

Hello.

I would like another CF card for my 400D. I already have 2x Sandisk 4GB Extreme cards and was going to order a 8GB one.

I've seen this on Amazon and wondered if it is compatible? I've not heard of UDMA but now the HC SD cards are not backwards compatible with normal SD so wanted to check.

Thanks.

Alternatively I may get this if anyone knows they are compatible? http://www.amazon.co.uk/Sandisk-Ult...OLE&s=computers&ie=UTF8&qid=1312193911&sr=1-8

I'll probably use it as a overflow from my current 2x 4GB Sandisk Extreme.
