for an update, my nextweb card unbuffered read is 10.75 and my buffered read is about 27.65mb, unbuffered write is 930.10kb buffered write is 2.97mb

this is with the file cahce (4096) tweak enable.

since I don't have a VZW card to test, not exactly direct comparison, but from the #s they seem to be comparable (in fact the nextweb seem to beat the VZW in the read test by quite a bit, but again, not direct comparison.)
