apart from the fact that they seem to be hard to source, this is a big
question about this interesting device for me too. I hope so, since

Actually for the ZIL you may use the a-card (memory sata disk + bbu + compact
flash write out).
For the data disks there is no solution yet - would be nice. However I prefer
the "supercapacitor on disk" method.
