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?
