As far as I remember, they say that you can
write to the device at the full speed of the serial
interface. And if so, the actual write-time doesn't realy
matter. This might have changed in more reasent devices...

And at (e.g.) 400kb/s, you're not *that* far from 72us/byte.
And 72 us is far better then the normal 5-10 ms in regular
EEPROMs, not ?
