First, you probably should have gotten the NM29A040V, not the "M"
series, because the M series will be a bitch to solder to the board.
The chips are equivalent, but they'll be harder to use.
Also, those "block read" and "page read" values are very confusing,
and they don't explain the table very well. First, there really isn't
a such thing as a "block read" function in the chip. ALL chip reads
deal with pages, not blocks, so I don't exactly know what that block
read rate means. Nonetheless, we will never get close to either
limits, so those rates won't have any significance to the user.
