questions about RN424 and RN524 new models
I have been a very happy Ultra 2 Plus user for quite a while, currently running OS6.8.0. I am a little frustrated, however, by the 2gb memory max capability, crashplan is a memory hog and I'm relyin...
My understanding is that the memory in the RN42x systems is soldered on, so it cannot be upgraded.
The RN524x supports up to 32 GB (2x16). It uses ECC memory (DDR4). As usual, this is unsupported by Netgear so it is at your own risk.
Some more details are on this thread: https://community.netgear.com/t5/ReadyNAS-Hardware-Compatibility/Memory-upgrade-for-Readynas-RN-422/m-p/1285452/highlight/true#M15958
I think it is a bit harder to reach the memory in the RN52x chassis (I only opened mine once, and that was a while ago).

oh really? Soldered on? That's kind of dissapointing. Absolutely no point in upgrading from my Ultra 2 plus to the 422 then. There could possibly be an argument made to go to the 424 in order to have a 4 bay with a bit more CPU speed, but with only 2GB of ram I'd be hesitant. That's actually the main thing insufficient on my U2P, the memory. Not really so much the CPU (as long as I'm not trying to transcode anything.
Sounds like 524 is the way to go eventually. Even with its stock 4GB of ram it would probably be enough memory for what I need to do. I could eventually move plex back to it also, but that is not really a strong requirement for me right now.
Do note that we use memory for caching to improve performance and free that up as needed. If you're using a lot of swap that would suggest that you may see significant benefits from having more memory, but it could just be that a memory leak needs addressing.
Like it or not soldered on memory (RAM) is the way things are trending. The RAM isn't soldered on in the 520 series and 620 series.
There are other uses for the fast CPU in the RN524X than simply transcoding. Also the RN524X has a 10GBASE-T port. 10G NICs, switches etc. have become more affordable over time.
I am using crashplan which is unfortunately a memory pig... 2GB is not enough.

It does use a lot of memory for deduplication. I ended up maxing my Pro-6 to 8 GB and allocating the maximum 32bit JVM ( between 3 and 4 GB). That was enough for 9.5 TB of data on the NAS (around 11.5 TB stored at Crashplan Central). I did have to tweak the retention settings at Crashplan Central (saving 3 months back) at some point. Turning off compression might also help. That was with Crashplan Home, the footprint with Crashplan Pro might be different.
I've put a 10GBASE-T card in a windows 10 desktop, and am running Crashplan Pro there (mapping the RN526x data volume to a network drive letter). Presently the PC has 8 GB of ram, I'll increase that to 16 GB later this week. It's rebuilding my backup from scratch, which will take a while.
