ReadyNAS ultra 6 plus mixture of HDDs
Hi,
I am running my Ultra 6 plus NAS using 3 of the 6 bays in X-Raid2.
1 is a Seagate ST3000NM0033-9ZM178 (128 MB cache)
the other 2 are Seagate ST33000650NS (64 MB cache)
These are all Constellation drives at 3 TB.
I get SMART errors on one of the Seagate ...650NS HDDs and want to replace it.
Constellation drives are no longer available here in 3 TB.
The hardware compatibility list is outdated.
Do you think I can swap the HDD for a Seagate IronWolf (64 MB cache)? I want to use the 4TB version as that has rotation vibration control even if the 1TB difference with the other HDDs will not be used in redundent mode.
If not, when is a disk compatible. Shouldn't it just have Sata (I, II or III) and the right size in inches?
Does the rotation speed matters (IronWolf differs from the Constellation drives).
Alternatively: other modern disks I can use?
OS: 4.2.31

No. I tried to say that I do recommend NAS-purposed drives like the Ironwolf and WD Red. Of course enterprise models are recommended too.
What I don't recommend is WD blue, green, Seagate DM, and other consumer drive models.

An Ironwolf should work just fine.
Ironwolf and WDC Reds work well in any ReadyNAS (including legacy NAS). Enterprise drives do also, including the Ironwolf Pro and WDC Red Pro models. I don't recommend using consumer drives anymore - they might work out, but the NAS-purposed models from Seagate and WDC are similarly priced, and intended for RAID/NAS use.
You can mix/match rotation speed - the system performance could slow down a bit, but I don't think you'll see any drop off.
On SATA, all newer drive models will have SATA 3, so that's not a concern. SATA 3 drives work in a SATA 2 chassis (which is what your ultra is). SATA 2 is already faster than mechanical disks, the performance boost with SATA 3 only matters with SSDs (or multiport SATA - which the NAS doesn't use).
Thanks Stephan,
Do you mean you don't recommend the Ironwolf or WDC red anymore if they are not the Pro versions? At least the non-pro versions are for NAS use.
Looked up the differences:
IronWolf (IW) vs IW Pro (IWP):
180 TB/year vs 300 TB/year work load
MTBF 1 M vs 1,2 M
Rotation vibration sensor 4TB and higher vs all capacities (that is why I was looking for at least a 4 TB model in the non-pro version)
guarantee 3 yr vs 5 yr
difference in rescue service.
