Differences between Phoenix and Pro

[nine9]

What are main differences between Phoenix and Phoenix Pro ?
or should I ask for who is Phoenix Pro for server use or desktop computers ?

[vaca]

Phoenix Pro has higher 4KB files random write than Phoenix.
We can measure about 50000 IOPS in IOmeter 2008.6 with condition:"32 outstanding I/O;4KB transfer size; 100% Random ;100% write ; Align I/Os on 4KB.

If you have server run applications with similar condition, the Phoenix Pro would be the better choice.
