Qnap Ts 464

[Enquiries]

Hi Nascompares,

I bought QNAP TS-464 weeks ago (this NAS was way over my budget, but I just love the hardware on this one)
Because of this, I can only buy M.2 ssd and RAM at the moment and use my 2 x External HD as storage via usb (all my files are here)
Could I get your advice on below?

I'm saving money to buy:
2 x M.2 NVme 2280
2 x 8GB RAM
4 X 10TB WD Red Plus

I'll mainly use it for Plex, photo sync, QuMagie, and personal storage.
For my purchase, I have options below:

Option 1:
2 x 8GB RAM
2 x M.2 NVme (500GB each)

Option 2:
2 x 8GB RAM
1 x M.2 NVme (1TB) - buy additional 1TB SSD later on.
Note: this 1TB is $18 cheaper than 2x 500GB

Option 3:
1 x M.2 NVme (500GB) - buy additional 500GB later on
1 x WD Blue 2TB 2.5" Internal SSD

Questions:
1. Is it possible to run QTS on just 1 M.2 NVme SSD? your article on this says that it requires two?
2. For my use-case, can I get away on just buying WD Blues instead? If I'm not going to do any heavy loads on this NAS?

Thanks a lot
