How would hybrid SSD/HDD-s fare in a raidz1 array??

I suppose for large sequential reads it wouldn't be much use, while for random read/write cycles it might help?

The value would depend entirely on how much RAM (and L2ARC) a system has. If the zfs ARC is large enough, the cache on the drive would not help much. If the system is rebooted often, then there could be some benefit since the drive cache is non-volatile.
