Out of touch things tech bros say #830635626148257: "Storage/RAM is cheap"
Just because storage and RAM cost you a fraction of the price of the other components in your gaming rig, doesn't mean those things are actually cheap!
Firstly, you're confused about relative cost vs absolute cost. Secondly, you're forgetting that not all computers are designed for the very same purpose.

@lunarood My plan is $45 each for 512 GB USB flash drives and some USB 3 hubs.

On an entirely unrelated note...
Behold my super clever plan for building a little storage server without spending much!
Rich Felker
@lunarood Oh, guess high end SSDs have come down a lot. Score!
Not interested in spinning rust, too much that can go wrong.
Luna R
@dalias oof, around $90 per TB!? That's over 3x the cost of helium-filled mechanical drives, and even rivals the cost of high-end SSDs!
Is there a particular reason you want to go that route?
Rich Felker
@lunarood @annaaurora For me it's noise, power requirements, and a feeling (that may not be accurate) that they're delicate, susceptible to physical damage, and impractical/impossible to do recovery work on if they fail mechanically.
Luna R
@annaaurora @dalias that's a fair point!

@lunarood
for me it's only really the noise that makes me want to use SSDs over HDDs for bulk storage (homeserver)

@dalias well, fwiw, USB flash tends to be just about the least reliable storage medium we have nowadays!
In any case, no matter the medium, it's going to degrade over time, so there's no point in relying on the robustness of any particular storage device... if you want reliable uptime, you need RAID, and if you want data integrity, you need backups. There's just no way around this.
In my view, the only actual gain from solid state storage is performance, not reliability. So it's HDDs for me!

@lanodan @lunarood @annaaurora Recovery of flash is a thing I've seen demonstrated. Recovery of ultra high density spinning magnetic storage that's been physically disturbed probably requires reproducing the original alignment in a way that's not physically plausible. At least this is my intuition for it.

@lanodan @dalias @annaaurora yeah, I agree regarding spinning disks in mobile devices. I touched on this elsewhere in the discussion as well.
Luna R
@dalias @lanodan @annaaurora huh, fascinating! I guess it's just whatever we happen to have stumbled upon, because my intuition is exactly reversed!
I've come across various companies doing platter-level recovery commercially (i.e. not just in an academic setting), but I haven't really come across flash recovery.
That said, it's all super expensive, and I wouldn't rely on it. If hardware failure threatens data integrity, that generally points towards the storage being improperly configured.
