This is one of those time of "Just becasue you can do something, doesn't mean you should"
Depends on what you're using it for; it's great for temporary working space, or for application/OS installations which you can reinstall if you've got a separate non-raid volume for data. For that matter, if you've got a decent backup, it's not a bad way to get extra speed - one big slow drive plus two smaller fast ones and automated backup is often cheaper than 4 faster ones (for a RAID 10 - striping + mirroring.)
Ditto if your important data is already on severs; until we moved to SSDs, the default configuration for developer machines at my workplace was dual 15k SAS drives. The assumption is that anything really important that's more than a day or two old is in source control or on a file server.
