Same thing with the Cisco CSS.  Even without a hard drive, you should have 2
of them anyway.  How do you plan to do software upgrades or other certain
types of maintenance without an outage if you don't have a second one?  

I've seen them flake out too, either by not passing traffic or by load
balancing getting messed up somehow.  In most of these situations, a
failover to the standby unit fixed the problem (this was with F5 gear).
