Hi guys I just got 4 SSDs for my FreeNAS box. This server is only used to serve a single iSCSI extent to my Citrix XenServer pool and was wondering if I should setup them up in a RAIDZ or a RAID 1+0 configuration.

This isn't used for anything in production, just for my test lab so I'm not sure which one is going to be better in this scenario. Will I see a major difference in speed or reliability?

Currently the server has three 500GB Western Digital Blue drives and it's dog slow when I deploy a new version of our software on it, hence the upgrade.
