Yes, it's often a really good idea. If you're doing software RAID on
Linux, you really should either disable disk drives' write cache or have
the system on a UPS with monitoring and automated shutdown. Most people
will opt for the latter. Using an SSD can boost write performance and
reliability for other systems. I just found this write-up on the topic:

Well, only if you're using swap space. If that's the case, adding RAM
to the system will probably be less expensive and a lot more effective.
