In my environment there are about 12 clusters ranging from the
210 to 3600.  I have only experienced 1 issue with a 240 that
lost power (UPS failed) and came back up on the backup partition
because (what I'm guessing) a failed fsck.

I did a reinstall (since the recovery was an older version) and
it booted fine.

I also did a handful of controlled power failures without issue.

I don't see the SRX being any more susceptible than any other
Juniper product and they have enough protections to prevent
catastrophic failure form corruption.

The only branch model that has RPSU is the 650 so there is the
risk of a PSU failure, of course.
