Hi Guys
I am putting together my first NAS, and I will try TrueNAS SCALE.
The Nas will be used only for 1 user in a homelab environment.
Primarily it will be a central location to store my movies as well as my design files.
Performance wise I don't need much, if it can stream 1 to 2 movies that will be fast enough.
All my other files are used locally and will be stored on the Nas for backup.
I intend to install a GPU passed through to a windows VM for use as a render node.
I have about 12Tb of movies currently and about 100Gb of design files.
Backups: I currently don't really have any backups (just important stuff manually copied around the place), so this NAS will be my
backup. I am aware that Raid is not a backup (I learnt this the hard way many years ago), so worst case if this Nas goes up in flames I will just lose a few movies.
Not happy, but nothing to lose sleep over either.
Once I gain experience (and money) in a few years I intend to repurpose this Nas as a backup and build a better (if needed) main Nas.
Currently I have purchased the following parts.
Case: Silverstone CS381
PSU: Corsair SF1000L
MB: Asrock Rack X470D4U
CPU: AMD Ryzen 7 5700X
RAM: 128G ECC (4x KSM26ED8/32HC)
Boot drives: 2x WD Blue SN570 250GB
Storage:
I will be using the on board sata ports of the motherboard.
I have a ROG Hyper M.2 card which I will put in 1 Kingston SKC3000D/2048G, and 1 Team Group TM8FPW002T0C101 NVME drives, mirrored.
The NVME will be used to store my VMs and my design files.
I am about to buy the main storage now and would like to make sure I am not doing anything too stupid before I put all this money into it.
Assuming the drives have a statistical life of about 5 years, I have guessed that 60Tb should be enough to last 5 years before I start replacing the drives with bigger ones.
I would like to to use no more than 6 drives as that leaves me with 2 free bays for future expansion (thinking possible NVR).
I have been contemplating 2 different paths.
1) 2x22TB exos drives as a mirror as that will be enough for the near future, and I can add mirrors as needed.
2) 6x16Tb exos drives in raidZ2 giving me about 56Tb usable space. (according to https://wintelguy.com/zfs-calc.pl)
For me I see the mirrored array advantages are that I have less money to outlay initially and I can just add mirrors as needed. If I understand correctly, rebuilding a mirror is easier than rebuilding a raidZ. Going the raidZ2 route means buying everything up front and being locked into the 56Tb storage size. Resilvering the raidZ is harder I believe, but I read that it is better to have 2 redundant devices as opposed to 1.
I am leaning toward the 6x16Tb and would like opinions if this is OK, or should I be doing something else?
Thanks in advance.
