UW's top speed is 40MB/sec, so there > shouldn't be any bottlenecks. 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.
