IMO, RAIDZn should perform admirably on the write loads. The random reads aspects is more limited. The simple rule of thumb is to consider that a RAIDZ group will deliver random read IOPS with the performance characteristic of single device. That rule does not apply to either read or write streaming data but only for small random reads pattern. If that means you need to construct small RAIDZ groups then do consider mirroring as an alternative.
So, mirroring, on jbods would give me the same/better performance than raidzn? Would that apply to fc drives or also to SATA?
