ReadyNAS Pro Business Edition with Os 6 and upgrade Bios (v2)
Hi all, lately I upgrade my Readynas Pro business Edition with a new CPU (E7600) 4GB of OCZ Platinum PC8500 and latest OS.
So far so good and work great. Now I want to upgrade the Hard drives.
...
So I can use 3TB to 8TB drives ?
I was thiking to buy 2x 4TB Red or Red Pro and use them with the 2x 3TB Red I already have and remove the 500GB drives. So I will probably going to use 4 bigger drives instead of 6 for now. Buy other later if I will need it.
I will have to check for the best $/TB

yes you should be able to use any size drives that conform to standard hardrive specifications.
do keep in mind, the bigger the drives, the bigger the array, the longer it will take for rebuilds/expansions/etc.
One should consider raid6/dual redundancy if they have 6 or more bay device. You do lose 2 disks of space, but the extra safety during a rebuild or expansion may save your data and your sanity.
But always remember, Raid is never a substitute for backsups. Backups = multiple copies of your data, on multiple devices, and ideally in multiple locations. Consider things like fire/flood/theft etc.
- At the moment I have 6 drives installed and when I did a factory reset in OS 6 I never had the option to use 2 drive for parity.
X-raid seems to select only 1 drive for parity up to 6 drive bay setup. On OS 4.xx i had the option to select 1 or 2 disk for parity
Maybe their is a work around in OS 6to switch to raid 6/dual redundancy on os 6, you must delete the default volume and create a new raid 6 volume. Then you can switch back to x-raid mode and it will stay dual redundancy with the regular x-raid auto expansion.
Another thing to keep in mind with dual redundancy, you would need to upgrade at least 4 disks before the array can expand.
But the peace of mine for extra safety is worth it to me, I run dual redundancy in my 6 and 8 bay devices, while my ultra 4 is regular single redunancy.
One more question: is it better to have all 6 bays filled with hard drives or only use 4 (2x4TB and 2x3TB) ?
Why i ask is because i have a bunch of 500GB that i could use to fill the 2 empty bays
