Hi @TMroy

I've just bought a F2-423 and it will be delivered tomorrow. I'd like to also buy at least one M.2 SSD (what are the benefits of using two?) but I can't find out whether I need a 'M' key or 'B' key type M.2? Please could you advise?

It's listed as NVMe (PCIe 3.0 ×1) only, so it needs to be M key.

So I added 2 16gb RAM stick and unit restarted and recognizes them with no problems. I also installed 2 M.2 SSD. My question is; Is there anything I need to do to set them up for caching or is it automatic? TIA

Would we have to install the nvme drive before we install TOS?
I've had my NAS for about 4 months now, I was thinking about putting an Nvme drive in it. But not if I have to totally set it up again.

Depends on how you intend to use the added NVMe drive; if it's just as additional higher speed storage, expansion of a raid or as a hyper cache, you can add it to your current setup & configure it as needed.

So to confirm. If I installed (2) 1 TB M.2 SSD's today. I need to go to control panel and format them through the hyper cache link? is there a link to instructions for this?

Are you adding them for the purpose of being a cache to 2 different existing storage pools?

The wizard for the cache within TOS is self-explanatory, so just follow it.

You can refer to the help center instructions to create hyper cache:

Please note that when an SSD is used as a system disk, it cannot be used as a cache disk.
