ReadyNAS nv+v2 Raid configuration
How can I setup multiple RAID configurations? I have four disks installed in a ReadyNAS NV+ v2. I would like to have Disks 1 and 2 in a RAID 1 configuration. Then Disks 3 and 4 as RAID 0. ...

You need to put the NAS into FlexRAID mode. With your NAS, that requires that you do a factory default. That starts a ~10 minute window where you can enable FlexRAID using RAIDar. This requires using the old RAIDar version (4.3.8) https://kb.netgear.com/20684/ReadyNAS-Downloads
My advice here is to do the factory default with only disks 1 and 2 in place, and then add disks 3 and 4 after you are in FlexRAID and confirm that you have the RAID-1 mode you want. Once that's done, you can hot-insert the two remaining disks, and set the RAID mode as you wish.
Personally I would go with 3 volumes (C for disks 1-2, D for disk 3, E for disk 4). That's because using a single volume for disks 3-4 results in a fragile file system. Failure of either disk results in losing all the data on both. Going with 3 volumes eliminates that flaw.

The labeling here is confusing, so I generally will post some info on how to correctly identify your model.
The original NV+ (called a v1 here)
- says ReadyNAS NV+ on the front panel
- runs 4.1.x firmware
- often has labels saying v2 or even v3 on the back or side.
The v2
- says ReadyNAS NV+ v2 on the front panel
- runs 5.3.x firmware
Both the v1 and v2 require you to go through the factory default procedure, and use RAIDar 4.3.8 to set up FlexRAID. But the boot menus are different, so it is good to make sure you know what you actually have.
You did not say if your drives already contain data. Note that while he didn't expressly say so, the process StephenB described will destroy your current volume and any existing data, so you'll need to back it up and restore it after the factory default. Unfortunately, there is no other way on your legacy NAS.
Thank you for the tips. I have tried several times. The first two drive go in as RAID 1, but the system doesn't give me a choice when I add in the third drive, it will aways go in as RAID 1, but without a redundant drive. Then, when I put in the fourth disk, it adds is as a redundant drive to disk 3. I'm a bit frustrated at this point. It seems like I will need to use two NAS servers. One in RAID 1 and another in RAID 0.
Is there anyway to change from RAID 1 to RAID 0 after the third disk is installed?
At this point, I don't have any data that I want to save. I completely remove all partitions before putting the disks in the ReadyNAS.
I am very grateful for any assistance.

Can you confirm that you have a v2 (running 5.3.11 firmware)?
