Any duration limit on the supercap? How long can it sustain the data?
A supercap on a SSD drive only needs to sustain the data until it has
been saved (perhaps 10 milliseconds). It is different than a RAID

them today ;)
I have one and i love it...I sliced it though, used 9 gb for ZIL and the
rest for L2ARC (my server is on a smallish network with about 10 clients)
It made a huge difference in NFS performance and other
