X-RAID2 vs RAID 5 or 6
What's the difference, technically between the readynas xraid technology and these other types of raid? Is it just dynamic volume expansion?
Related to this article on RAID 5 (and even 6 if you follow the previous article he links) how does xraid2 compare? Is it vulnerable to the same Unrecoverable Read Error situation?
If you're very concerned with data integrety should there be a loss of a drive, which configuration would you recommend? RAID10? X-RAID2?

- mdgm is correct in the RAID configurations.
The XRAIDs will allow for dynamic volume expansions. The two options with the ReadyNAS is XRAID and Flex-RAID. The XRAID will help maintain your volume, where the Flex-RAID will have a static volume.Hi I have a readyNas Ultra 4. It had 4 disk but 2 (disk1 and disk2) of them were marked as dead/failed. I tried to replace those 2 disk but the rebuild failed (maybe because disk 4 also starting to fail during replacement)...
i'm trying to recover. in the recovery tool i need to pick the raid scheme (raid0, raid5, raid6 etc), i'm plugging in the original disk 1/2/3/4 - which raid should i pick? i'm trying raid-6 but seems to take a long time to scan...
- 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).
