ReadyTIER with ReadyNAS Pro 6
Hi,
I've got a NAS Pro 6-bay system, currently on NASOS 6.9.5 hotfix 1 and loaded with 4 x WD RED 8 TB drives in FlexRAID RAID 5. Primary use case for the unit is as an NFS server for my VMwar...

So...here's my putting-the-cart-before-the-horse question: Do you know of any reason this shouldn't work when adding a 512 GB RAID1 SSD tier to the existing volume?
It should work in the Pro-6 (though you do need to change to flexraid in order to use ReadyTier).
The main challenge is adapting the trays for the SSDs, and you've already found mounting brackets for that part.
ReadyTier isn't caching the metadata, so if the SSD RAID group fails you will lose the volume. Your SSDs will reach their write limits at the same time. So you might want to replace one of them about half-way through it's expected life, so you can stagger the replacements.
Okay, I fibbed about waiting for the update to be prompted. I had some slack time tonight and went ahead and shut down all VMs and updated the NAS to 6.10.0...it succeeded and promptly updated itself to 6.10.0 hotfix 2 upon rebooting, and all appears to be well. SSDs and mounting adapters are still projected to arrive tomorrow, so hopefully we press the big "go faster" button then.
I haven't been able to find the reference I saw earlier about removing the SSD tier once it's in place, but I would SWEAR that it said you could remove the tier RAID group without losing the volume. Would REALLY like to find that again before I take irreversible steps.
Ah, found it!
kohdee mentions it in a different thread here: https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/ssd-tiering/m-p/1661052/highlight/true#M151050
Hopefully I'm reading this correctly as saying you can remove the SSD tier(s) without data loss
A tier is just a special RAID group. You can incrementally expand a tier as long as your Tier is not a RAID 0, and you can also remove a tier. When you are looking at your System > Volumes screen, select the RAID group Tier (the one that says SSD) and click the circle X underneath the dropdown box. It will restore you to pre-tier configuration.
