How fast is the O2 when reading RAW files?

[frozenpeas42]

Hi, I've been looking at getting a PMP, primarily as a way of viewing my photos when I am travelling - reviewing and deleting them.

I am shooting 21mp RAW files, which are about 20mb each. I know that the O2 supports the RAW format, but I am worried about the speed.

Can someone please tell me about their experience using the O2's photo library. Do you think it would be feasable to transfer 5-10 gig of photos using USB OTG and review them?

I am actually going to get the Cowon V5, but If the O2 can do it then I will have more faith in the ability of the newer model.

Thanks!
