Do you know what CPU's are in

NV+

102

202

Yes. The NV+ v1 (Sparc) uses an Infrant Infrant IT3107 Storage Processor. It's a Sparc CPU. This is the same model CPU that was used in the NV released back in February 2006. It's very old now.

The NV+ v2 released November 2011 uses a Marvell ARMv5 1.6Ghz CPU.

The RN102 uses a faster ARMv7 1.2Ghz CPU.

The RN202 is faster again with an Annapurna Alpine AL212 (dual-core) 1.4Ghz CPU

The RN212 is still faster with an Annapurna AL214 (quad-core) 1.4Ghz CPU

The RN102 has 512MB RAM whereas the RN202 and RN212 have 2GB RAM. As is typical for products using ARM CPUs, the RAM is soldered onto the motherboard.

Isn't X-Raid a Netgear proprietary solution, I usually stick with standards like Raid5 to aid data recovery

X-RAID on Sparc ReadyNAS units was a bit different but it still used standard RAID levels. It used RAID-4 for X-RAID, but on those units for volumes created on RAIDiator 4.x, the volume used a large block size. This makes data recovery slightly more complicated but it is still possible using a standard x86 Linux machine.

All newer models use X-RAID2. X-RAID2 uses RAID-1 for two disks and RAID-5 for three or more disks. You can also use dual-redundancy (RAID-6) in systems with four or more disks if you wish. There's nothing proprietary about the RAID levels used. What we have done is to automate expansion. You don't have to use X-RAID2 if you don't want to.

4 bay is always better but I want to cut power usage, besides cost of kit is always coming down and you get better hardware developed as time goes on, so best to get what I need now.

Just wanted to make sure you were considering the options and the fact that going with the RN102 you'd need to use quite expensive disks to get higher capacity than what is possible with the NV+, even the NV+ v1 (the Sparc version that was limited to 4x2TB disks).

Generally it could be at least a few years between NAS purchases (if not more) so it is best to make a judgment as to how well a unit will suit your capacity needs for the time you think you will keep it however short or long, whether it will cater for your data growth during that time etc. You can start with smaller capacity disks and upgrade to higher capacity disks later on of course.

I am only going to use for backup so will be powered off most of time

You can use a schedule to power the NAS off and on to help with this if you wish

using as a storage for plex makes no sense when I can just stick a big hard disk in or outside PC..

Well if you connect a disk to your PC for use with Plex if that external disk fails all the data is gone. So it would make sense to have a backup of that data e.g. on the NAS.

No important data should be stored on just the one device. That goes for data stored on the NAS too regardless of what RAID level is used. If the only copy of data is on your NAS then it's not backed up.
