My issue is not directly related to physical hard disk performance (even if
that is another point), but on RAMDISK performance.
Devsk is right: I am modelling memory performance.
A ramdisk without a file system on it (such as the one obtained using the
ramdisk create command) is like a raw disk.

he is modeling memory copy...I think. He is expecting DDR3 speeds (not sure but
around 10-15GB/s range)

Or compression. It turns out that /dev/zero compresses extremely well.

Does "TestPool" use dedup? If so, turn it off and try again.
