X-RAID2 (available on ARM and x86 ReadyNAS) uses standard RAID levels, RAID-1, RAID-5, RAID-6.
With two disks it would be RAID-1, with three disks RAID-5 and optionally with four or more disks installed in a 6-bay or greater ReadyNAS you can use X-RAID2 dual-redundancy (uses RAID-6).
X-RAID2 has multiple layers. So with say 2x2TB + 2x3TB you'd have a RAID-5 layer of 4x2TB + a RAID-1 layer of 2x1TB.
If you value your data you should make sure you backup your data regularly (e.g. to a USB disk).
