Difference Betweeen Ultra and Ultra II

I have 2 Compact Flasd ii cards  (silver on top of card “Compact Flash”)

1 is 1 GB the other 2GB

I have recently ordered a new 8GB card

The invouce says 8GB Ultra II

bur the card just says Ultra Compact Flash 30MB/s 8GB

I am confused because the Sandisk web site does not seem to mention Ultra ii anymore

is this card effectively Ultra ii but just repackaged? and now faster?

Any help would be appreciated

My other concern is that my ageing Sony DSC F828 will not be able to write at this speed anyway I assume it will just be slower if anything but still compatible?

Many Thanks
