Then ECC brings a benefit

But only because of the raidz2

Everything else that you said has 0 benefits from ECC

yeah I have to. so many lifehacker tier guides said "just pick up old pc parts and smash them together" and FreeNAS forums were very clear about how important ECC is

Data storage is directly affected by raid z2, Plex is not

im still not sure about what to run on my NAS

if your memory is fucky with z raid it's bye bye

ZFS, unRAID (XFS), mergerfs + snapraid

In my limited experience FreeNAS and zfs z2 has been good to me

How many disks, how many reliable external backups? @Goz3rr

4 disks, but i want to expand

ZFS can't expand with single disks

one hard drive already broke, it sent a mail, resilvering was a breeze

How many disks do you want to have?

i have 8 bays

How large are the single disks going to be?

8TB

Mh that's too large for raid6

i don't want to run hardware raid

Does your NAS have reliable external backups?

Or are you using raid as a backup? (don't)

there's nothing on there

there's 4 unpartitioned disks in it

and a 500GB 970 evo plus

How much reliability do you need?

And do you rather read or rather write?

(you can see selecting a raid level is science)

i was just going to put plex and a torrent client on it

i don't buy into the raid5 is broken meme either

So if it crashes for a day or two and is barely accessible during restore, it's not a big deal?

single parity disk is fine for me right now

and 3 data disks for 24TB effective

Then go Raid6 anyway

raid6 is two parity disks

Yes believe me

I've had the second disk failing during a restore way too often in my life

if i go raid6 with 4 disks i might as well go raid10

same effective space and a way better solution

`Or are you using raid as a backup? (don't)`
w-what senpai

I thought you want to expand to 8 disks though

i do

@futuremoe yes raid is NOT a backup

Once you have 8 disks, Raid6 is nicer than 10

Except for writing speed

when you say you had second disks fail during rebuild

did you ever scrub your arrays

hmmm

Nvm I misread

Did you ever = yes
How often = not enough

Still I wouldn't risk it

raidz3

or gtfo

yeah let me just throw 24 TB away

I'm still for Raid6 here

so I need another server to backup my server?
are synology servers as trash as I think they are?

synology is overpriced hardware with a shitty UI

Yep

but it works if you dont want to fuck around

yes and yes

And a shitty UI

i meant ui not io lol

You could just encrypt your entire NAS and put it on Azure archive storage. They're a few $/tb as long as you don't access it @futuremoe

That's basically storage tape as a service

azure is €0,0017 per GB, aws is €0,004 per GB

cold storage

Cheap af but takes a day to access. Tho I would encrypt everything before uploading it because it's Microsoft

Yeah that's 1.75€/TB

but you pay out the ass for data retrieval

Yes but that's just for emergency

I think it's ok for backups

Let's say you need it once every 3-4 years

archive storage is fine. what's the difference between hot/cold?

Hot = expensive to store, cheap to access
Cold = cheap to store, expensive to acceas

Hot is for your little files that you need every day, cold is for backups

and archive is cool on steroids?

Yes

Iirc the cheapest plan of azure for archiving has one day of latency to access a file

it would be 10 € a month for 5TB archive

Like, you have to request a day in advance

that's fine it's mostly my blu ray rips

I doubt it's going to cost that much but I can't check rn

I'm not paying that much

first 50tb azure archive is €0.0019 per GB a month

Switch location away from Germany

Select some US location

They might be cheaper

Northern Europe is cheap too

That's Ireland

Right

For some reason that's called North lol

I should check my Azure bill

I pay about 200 € / month for all the shit I have but I have no clue what I'm paying for the single services

I know that I have about 30 TB in cold storage

But I also have some VMs and some databases

anyways

i want to start with 1 parity disk now

and upgrade to 2 at some point

when i upgrade beyond 4 disks

all my drives are from different batches/sellers so i'm not too worried about them all failing at the same time

i intend to use the HDDs as bulk storage for media library etc
