How to get Data off a Failed ReadyNAS NV+ Model RND4250-100EUS
Hi, I have an aged ReadyNAS NV+, which has been worked well for many years. It has two 500Gb discs in only 2 of the 4 slots. However, it recently failed to boot with a Kerel Panic message. I have ...

This worked fine thanks, so I am just checking that I have all the data now.
Great. Then disk 1 has likely failed, and needs to be replaced. But first back up the NAS đ.
You don't need to match the model you are using with disk 2, but you do need to use a drive that is at least the same size.
I don't think there are current mechanical disks that are only 500 GB, so I'd go with something larger. Your NAS can't handle anything bigger than 2 TB. Since the price difference between 1 TB and 2 TB is small, I'd personally just get 2 TB. When you replace the second disk with a 2 TB model, you will end up with a 2 TB volume (the biggest RAID-1 volume possible with your NAS).
I recommend either a WD Red Plus (WD20EFZX), or a Seagate Ironwolf (ST2000NT001). Avoid the WD Red (WD20EFAX) - it is an SMR drive, which isn't a good choice for ReadyNAS.
