Hello I have tested freenas. with
4 x 500 GB WD enterprice drives and 1 x 250 GB random disk in raidz2
I max out the netcard 110 MB/s.
And if I run 4 x 500 GB WD enterprice drives
I also max out the netcard 110 MB/s
But if i replace the 250 GB drive or one of the other 4 drives with a WD Caviar Blue 500 GB and ofc setup the pool again.
The tranfer performances drop to 5 MB/s to 18 MB/s
Tried it on openindiana with Raidz2 also. And same result, the Blue caviar 500 GB take down the performance from 110 MB/s to 5 MB/s to 18 MB/s
Can anyone explain why ?
WD500AAKS Sata 3 GB's
UPDATE: I got 1 Blue Caviar drive on my PC exactly the same as the one i tried in my nas. I backed it up and plugged it to my nas server. And now all runs fine..
So must be the first Blue drive there is close to its DEAD :D
