What's the best filesystem/volume management choice, /tech/?

>ZFS

>HWRAID/mdadm+LVM+WhateverFS

>BTRFS

Also, what's the general minimum computer specs needed for a NAS? I heard you can do it with an ARM SBC like a Pi.

>>901778

Sounds good, can you give some details? How important is a good CPU / RAM, and what did you use? How did you setup the SSD caches? How much did you pay?

enjoy your paranoia

Preferred: One of those 1watt standby NAS boxes in RAID

Cheapest and simplest: plug a drive to your router

There's backdoors alright, not just wd though. I remember a list from the cia leak that had 9 hd manufacturers listed, for firmware backdoors. Do the drives come backdoored? Maybe not, but it's easy to get one backdoored because the firmware is rewritable.

You can get a serial terminal on some of the arm hd controller chips, perfect backdoor platform tbh. What I used to do is cut the pin on the controllers memory that makes it writable, but now the memory is integrated and the chips freak out because they can't log things like power on hours. They could have used it as cache so it had to be writable but it was just firmware that should never change and yet it was writable. A firmware update jumper could fix this bullshit.

Someone should make a firmware that blocks all firmware updates, at least we could consolidate to one or two backdoors.

Yeah I remember reading about that and how they'd intercept shipments. But since I don't have a security clearance and am not a cp collector I'm gonna guess they wouldn't bother spying on me. Too much work for no reward.

>>901810

>but it's easy to get one backdoored because the firmware is rewritable.

wait doesn't that mean it's rewritable by the user too?

>>901819

Yes, some serious hacking might be needed because the process is different for manufacturers and models. I wish the memory was still separate because you could do a dump without going through the (((controller))). The system running on a hd controller is sophisticated enough to have a self deleting backdoor or one that deletes itself if it detects an image dump read pattern. There was a good defcon talk about this "running linux on a hard drive" or something. There are no coincidences here.

If you just need NAS and not a general purpose lab machine on top of it, I'd just buy a Netgear ReadyNAS or something similar. They're super easy and have a nice management interface, but are Linux based and can be hacked a bit if you are so inclined. If you need NAS and also computational capacity e.g. a VM hypervisor, build your own rig and install ProxMox OS with ZFS on Linux running alongside it.

>greens

Discontinued anon, Greens also die hardcore when being used for NAS purposes, if budget is a concern get blues instead.

>>902390

They're not meant to be used in RAID configuration. There's a program called idle3-tools which you can use to alter the hard drive firmware to make them act like Blues. I have a couple of WDC_WD20EARX with 3+ years on them and no errors logged. That said, Reds or HGST NAS drives are better fit for the job.

>>902390

why should they ?

NAS drives is used far less then in a desktop

My setup:

Old laptop running 24/7. 3 external hard disks formatted with ext4, using mhddfs (FUSE) to "combine" the storage together without suffering from redundancy/reliability issues. SSHFS (FUSE) to connect it to my primary laptop.

>>902390

Greens were made to spin down after 8 seconds idle, blues after 300 seconds. You're right they probably shouldn't be used in a hardware raid but they were absolutely A-Ok for my setup. When they're always active and syncing to stripe across all disks they're never idle and spin down isn't and issue. Another point is TLER, which again isn't an issue in this software raid but would beneficial in a hardware raid environment.

>>902425

said blues meant reds.

>>902433

what's the point of the key?

if some nigger is going to steal your shit he's just going to take the whole box. if some cianigger is going to tamper with your drives then they can easily defeat what looks like a simple lock without you knowing it.

>>902434

You'd have to ask Lian Li. I keep the key because I worry that gravity and tiny vibrations could someday jiggle the latch closed leaving me to fuss with the silly lock.

>>902434

Not when bolted down

>>901769 (OP)

>what's a good setup?

That very much depends on your budget and requirements, which you should have posted in the OP you humongous queer.

whats the point of NAS? sounds like dumb idea

Is it a bad idea to set up NAS and media player as one piece of hardware?

Like some Atom board with 6 SATA ports and HDMI?

So you can hoard all your porn and Chinese cartoons

>>902550

If you have just one computer maybe. As soon as you have at least two computers, common storage which can be accessed simultaneously and independently comes in handy. The more computers you have the more useful it is (the alternative being files being dispersed over multiple computers' local storage, likely partly duplicated and becoming somewhat of a mess with time).

>>902557

you can hoard data on PC, don't need stupid NAS

>If you have just one computer maybe. As soon as you have at least two computers, common storage which can be accessed simultaneously and independently comes in handy.

Why would I have more than one computer? you think I am idiot?

I don't have four hands and two heads, so I can only use one computer at time, so why buy more of them?

And if someone has desktop + laptop, the only time you would use laptop is when you was on some few day trip or in hospital or somewhere. in that case it's just better to get your projects data onto your laptop, travel and use it, then when you come back put your projects back onto desktop.

But using any PC outside your house is idiotic, it can easily be stolen from your hands and disk encryption won't work because laptop will be running when it's being stolen.

speaking about encryption, that's another thing that makes NAS pointless. If you encrypt NAS (how?) but have it in another room, anyone can just come and get it when it's running and has password in RAM.

>>901769 (OP)

Mdadm software RAID 10 with LUKS is pretty good. Running 4 × 4TB HGST 7200 drives now. Pretty comfy.
