Oh, and with 4x 3 TByte SATA mirrored pool is pretty much without

You can also use raidz2, which will have a little more resiliency.
With mirroring, you can lose one disk without data loss, but losing a
Hi guys, sorry in advance if this is somewhat a lowly question, I've recently
built a zfs test box based on nexentastor with 4x samsung 2tb drives connected
via SATA-II in a raidz1 configuration with dedup enabled compression off and
pool version 23. From running bonnie++ I get the following

I've since turned off dedup, added another 3 drives and results have improved
to around 148388K/sec on average, would turning on compression make things more
CPU bound and improve performance further?

Thanks everyone, I think overtime I'm gonna update the system to include an ssd
for sure. Memory may come later though. Thanks for everyone's responses

You can't really do that.
Adding an SSD for L2ARC will help a bit, but L2ARC storage also consumes
RAM to maintain a cache table of what's in the L2ARC. Using 2GB of RAM
with an SSD-based L2ARC (even without Dedup) likely won't help you too
much vs not having the SSD.
If you're going to turn
Ah ok, I wont be using dedup anyway just wanted to try. Ill be adding more ram
though, I guess you can't have too much. Thanks
