Hello everyone!
I need to tell you this! I am delighted with this ZFS implementation on my iMac. I don't know where to begin.
The raidz1 option is beyond magic. Combined with the self tuning, I get extraordinary writing results on my external Thunderbolt2-HDD drive with 4 2GB HDDs.
Not to mention the read! With 85% used I still get 402MB/s wright and 1560MB/s read!!!
I have the backup on a USB3 HDD, and I get maximum wright speeds on that drive, according to the Manufacture provided specs.
I can not thank you guys enough!
With the warmest regards
Oskar
