longpost, but if anyone can weigh in on the specifics of my situation and fast-track my learnings I'd appreciate it. an anon in the previous thread suggested I get a raid1 setup for my data storage. I've only done minimal research so far.

Ideally if I could wish some magical device into existence it would satisfy the following
> plugs into my computer via usb to transfer files to and from the pc/storage
> retard-proof features that protect it from avoidable hard drive failures
> in the situation of a hard drive failure, protects data from being lost (why anon suggested raid1 to me in the first place)
> not connected to the internet (NAS not an option)
> is compatible with connecting to any of my three computers (all with linux operating systems installed), not restricted to one pc (rules out softraid?)
> Any installation necessary for the enclosure external hdds can be done on a linux operating system (no external raid manager software that's exclusive to windows/mac).


Am I ruling out "software raid"? "hardware raid", "direct attached storage" seems like what I'm looking for. Are the three options on simply "softraid"(internal), "hardraid" (external) and nas (network)? Or is there another option I should be aware of?

I've looked up hardware raid controllers on /g/, and besides /g/ shilling softraid and saying hardware raid is outdated, all the bigname devices I'm finding online require windows or mac for the external raid manager software even when they can be used otherwise with a linux pc. There is plenty of generic chinkshit with sparse information that doesn't mention this sort of thing and says it's compatible with linux (no description of any raid managing software), but I don't want to buy some no-name crap, the entire point is I want something trustworthy. Especially because /g/ says that if the raid controller dies I am fucked unless I can find a replacement of the same model or the data is lost forever.

Thanks if anyone reads this and can weigh in. I'm not tech-savvy (only use linux because I'm too autistic to pay for windows and too retarded to pirate it).

what I mean is that I want to be able to connect to one computer today, another computer tomorrow. not both of them at the same time. from what I understand softraid can't do this.

from what i've seen, any kind of hardware RAID available to you will be either placebo-effect stuff that doesn't actually scrub data to check for bit-rot, or exorbitantly expensive enterprise hardware

your options:

bulletproof but really expensive for a given amount of space:
- cloud storage

pretty much bulletproof outside of an act of god, but requires:
- ZFS raid server in your house, configured properly for scrubbing (linuxtechtips failed at this and lost their data lol!)
you will need at least 1gb of RAM in the server for every 1tb of disk space in your ZFS server, which can get expensive

unlikely to be a problem, with modern high-capacity hard drives, probably:
- one internal hard drive and one USB hard drive, every week or month or whatever, plug the USB in and sync it with a filesyncing program like FreeFileSync - quickly review the sync changes by eye to make sure they look sane
