It takes me to Plex and I chose Netgear "v.1.42.2.10156-f737b826c September 18, 2025" Which only has Arm7 and Win64. I tried the Arm 7 and it fails. I believe the Ultra 6 is Arm5. 

No, it is x86 (so select the Intel 64-Bit package).

It has no GPU, so transcoding performance isn't great.  Best to use direct play on that NAS.

The Ultra 6 (RNDU6000) uses a dual-core D510 atom processor.  But there is a similar Ultra 6 Plus model (RNDP600U-200) that has an E5300.

I upgraded it to 6.9.5 firmware and added ram. It still booted so I assume that it took the ram but I don't know where to look to find out.

Download the log zip file and open mem_info.log.  The first line is MemTotal.

If you look in dmesg.com you can confirm the processor (search for smpboot: CPU0: )

I suggest enabling ssh, and also updating software to 6.10.9 or 6.10.10.  Note 6.10.10 removes the app install from the web page, but you can still upload plex by pretending the deb file is a firmware update.

Note you need the x86_64 firmware for your NAS.

all the links for drive compatibility are dead.

Not surprising, since they haven't updated it for years (and stopped manufacturing the Ultra 6 back in 2013).

Get NAS-purposed drives (WD Red Plus, Seagate Ironwolf, Toshiba N300) or enterprise-class.  Desktop drives are mostly SMR technology, which don't work well with ReadyNAS.
