Hi Eric,

I'm using drbd over zfs raid 10 ssd without problems.

As I know, RAIDZ has bad performances with block devices, so I advise 
you raid 10

You don't need this, zfs on the first layer already compresses the data.

Furthermore, zfs works better with physical disks

Emmanuel Florac, zfs replication is asynchronous, even you can set it 
every minute, you always lose some data after a node failure
