How to plan storage drives for my build?

I have edited this post since the time it was originally made. Because i realize many here use UnRaid as opposed to TrueNas?

I am in the process of procuring h/w. I already ordered the following

MoBo: Asrock Z370 Pro4
CPU: i5 8500T

I am planning to use this NAS build merely for storage purposes and not for gaming or media serving. I do intend to run either a VM or some docker containers which will run some python scripts for web scraping.

RAM:

is a 64GB Crucial Pro RAM an overkill for my needs?

SSD

The motherboard I ordered only supports Gen3 nvme m.2 SSD. however, it is hard to find a Gen3 SSD and they are expensive. Is it Ok to use a Gen4 SSD? [WD SN560 1TB NVMe Gen4x4 Internal M.2 2280 SSD] - these are less expensive than the Gen3 ones.

Storage:

I am looking at this from the NAS killer 6.0 as a reference.

  • 1 SSD cache for docker containers and VMs
  • 1 HDD cache for large file ingest
  • 1 parity drive
  • 6 data drives (48TB usable)

I have about 6-8 TB of data to be backed up.

I have no idea how many storage, parity, cache drives should i be using. Can someone provide some suggestions?
