I think you are not studying the specs closely. For the 24LC512, the 5mS 
is MAX; I  get
about 3mS normally.

The other thing is that you can place 128 bytes into a write buffer so 
that 3mS is needed
for the whole 128 bytes. So It writes faster than you think.

If you have room, use two RAMTRON SPI memories, they are 32Kx8 each, so 
you can reach
65K without ANY waits to flash the parts.
