Thank you! I feel reassured about the replacement.
I had read ages ago about teh parity but forgotten - or as i say I must have slept since then. Thank you for explaining it in more detail. Pretty neat.
One follow up regarding replacement drive size.
I found in another post - by you I believe - the concept of
""sum the disks and subtract the largest". " to find storage space in Raid 5.
Using this format, - again my orig confi is 4x1TB
Can I use 4x4TB replacements and still be under the 8 TB expansion limit.?
The growth would be 9 TB (since your starting point was a 3 TB volume, and 4x4TB would give you a 12 TB volume). 9 TB is ~8.2 TiB, which unfortunately that is just over the limit.

(4x4)-4= 12 and 12 is 8 larger than original 4
Thank you again!

One option open to you TMcL is to convert your Pro 4 operating system to the current one of OS 6, this has no expansion limits

The process involves reformatting the disks, so you do need a full backup if you want to do that. Going to 4x4TB requires destroying the data 4.2.31 anyway, so if you want that size you should certainly consider converting. Many folks have here have done it. Some of the other advantages are that you'd have SMB 3 (current version of SMB used by Windows 10), have a current of version of linux, and be able to use ReadyCloud and Plex.
The downside is that Netgear won't offer paid support if you convert.
My own Pro-6 is still running 4.2.31, and is at it's expansion ceiling. When/if I need more space I plan to convert it.
