Re: Perf in UDMA Mode 5



See nothing strange about it. The figures dramatically demonstrated the
difference between burst speed and throughput speed of both hard drives.
Throughput speed is what's important for speed of the OS and applications.
The second is good for storage, not OS installed usage.

You should do a write test of the same, not just read test.
