Ready NAS Pro Business Edition and Western Digital Red 6 Tb Hard Disk
Hi have an old Ready NAS Pro Business Edition with the following configuration:
i'd like to swap the Seagate ST2000DL003 (1858Gb) and the WDC WD30EZRX (2790Gb) with 2x WDC WD60EZRX (roughly 5580 Gb).
The questiions are:
1) Is it possible?
2) With the Raid X-RAID 2 will i obtain roughly 4x4tb +(2-1)x6Tb = 22 Tb? Is it correct?
3) In the future if i gradually switch (once at time) the 4x4Tb Drives with 4x6Tb will i obtain a Total capacity of (6-1)x6Tb = 30 Tb..?Is it correct?
thank you very much for the time you dedicate in helping me..

Your capacity math is correct, but the expansion will fail with OS 4.2.
There are two limits to growth with OS 4.2:
(a) a volume cannot expand over 16 TiB
(b) a volume cannot expand more than 8 TiB from it's starting point.
You are right at the expansion ceiling for (a) (17 TB is ~15.5 TiB), so you can't expand any further.
Your best option to expand your NAS is to switch over to OS 6. That will require a factory reset (destroying all your data) - but there is no way to expand the capacity of the Pro that doesn't include a factory reset.

Hi,
first of all thank you for your help.
Just another question:
I've read here that on my old ReadyNAS PRO 6 is it possible olnly to install a Raidar 4.2.x firmware.
As i understand instead you have written that with a factory reset is it possible to upgrade to the new OS 6.x firmware also my ReadyNAS PRO 6.
May you please give me a link of the right procedure...?
thank you very much.

Netgear doesn't support OS 6 on "legacy NAS" but many people have done it. There are various posts here on the procedure, one is here: https://community.netgear.com/t5/Using-your-ReadyNAS/Ultra-6-OS-Upgrade-from-4-2-30-to-OS-6/m-p/1181060/highlight/true#M120724
