Why I could not ask ;-) Just Kidding !

I think a bit of experimentation will be necessary.

What I could say is:
1.) Blob Pages are not shared between blob's, so the tendency is to have
more unused/wasted space with big page sizes (ok, HD space is not
important nowadays)
2.) If a Blob is small enough to fit in the data page it will be, so
less records will be stored on the same page which increases the number
of pages to be read (So small page size should avoid this)

But I would go for 16kb page, and have a test for performance and size
on 8kb and probably 4kb too and see if it's significant.

see you !
