RN424 , 4x 8TB WD Red Plus failing after 120 days?
This problem is with a RN424 with 4x 8TB WD80EFAX, all identical HDs purchased at the same time as the 424. The system has 6.10.4 Hotfix1 and has been up for 120 days, I had not even transferred all ...

Pfeww Hurray
Thank you to all for the support
Added note – WD has not replaced the failed disk yet.
When I will receive it (if I do), I could get another NAS, maybe a 2 bay one, and I could twin it with another 8TB on RAID 1, purely for backup duties.
Unfortunately NETGEAR seems to have disappared from the UK market, for reason I cannot really fathom.
One simple question – in the event of a NAS failure – can a RAID1 disk be read by any LINUX machine or would I need recovery software (which is kind of pricey)?

Yes. You would need to install mdadm and btrfs on the linux system. But no paid software packges are needed.

It is 7200 rpm. https://www.pcmag.com/news/western-digital-confuses-everyone-with-5400-rpm-class-hard-drives
Note after this came out, WD put 7200 rpm on their datasheet (with a footnote talking about the performance class). Not sure if they updated the firmware to report the actual speed.

Ouch. That possibility is why I also test mine before putting them in my NAS.
