14MB/s is the maximum internal transfer rate. Also, we're talking about
write performance here, which will likely be quite a bit slower than read
performance. As I said before, a more realistic number should be had with
rawio or by measuring actual real-world transfers. Unless all you do is
write zeros with dd all day long, I don't think that that is the best
measure of performance.
