> "it is trying to protect the hard drives and data through fires of up to 1550F for 30 minutes and 10 feet of water for up to 72 hours."

Trying. It does not look fire proof to me, especially the power supply. Did they ever tried to submerge it in a pool for 72 hours. They forgot to say also if those specs are operating or nonoperating.

The review seems quite clear on that point, even from the line you quoted. It's protecting the hard drives, not the NAS. The electronics (including the external power supply) are not encased in the safe are -- only the drives are.

> The concept is more that one can pull the drives out, put them in another Synology NAS, and be up and running quickly after a fire.

Even if you do that you should never rely on those drives longer than it takes to pull the data off. And even then I'd advocate for an off-site mirror rather than to rely on drives surviving any kind of fire.
Yeah, I'm trying to imagine a scenario where this solution would be better than off-site.

The only thing I can think of is CCTV footage that might be too heavy to transfer over slow links in remote locations.

I did not read any fire or water testing. It seems like a not very enthusiastic review...

Have you tried reading the article before commenting?
During a fire even a "fire safe" will reach extremely high temperatures. The goal of the box is to keep the internal temperature below 800 degrees (the autoignition point of paper). I can't imagine the internals of the NAS actually surviving above 200 or so degrees, especially given the fact there is less insulation than a standard fire safe.

A much better option would be to buy a gun safe from Costco or the like with a large internal volume and ethernet/power passthrough ports. The air inside will act as an additional insulating layer buying you time.

>below 800 degrees (the autoignition point of paper)

Isn't the autoignition temperature of paper like a third of that?

They never even mentioned what unit they're working in
800 degrees kelvin! Of course ;)
It's 451 degrees Fahrenheight, of course.

Well, no. Actually it's a bit more variable than that, but "Between Fahrenheight 424 and Fahrenheight 475" doesn't make as punchy a book title for some reason.

There are a bunch of fire tests for this thing on youtube.

Can you imagine being on the engineering team for this thing and NOT fire testing it? That's the fun part!

Testing is expensive and the development process can/must be tailored. /s
I’d settle for a jbod enclosure that isn’t loud and doesn’t randomly die/kill the drives.
I can't see 30 minutes of fire protection being all that useful in a big fire.

The Curie temp of hard drives seems to be quite low, depending on the exact platter formulation. A target temp of ~800C is far too high. In a hot fire, I wouldn't expect the data to last more than 10-15 mins,

72 hrs of water protection might be enough.

But this still makes less sense than keeping copies of data off-prem somewhere - preferably a very very long way away.

And preferably multiple copies.

There may be reasons (privacy, security...) why you might not want to do that. But still. An encrypted off-prem solution, even if it's multiple NAS boxes in various offices and not a cloud thing, is going to be far more robust than a drive safe.

If the nas is deployed in a building with a good fire suppression system, a 30-minute rating may be sufficient for it to survive long enough to allow for the system to activate. At that point, it may be sitting drenched for quite a while before people go in to recover it.
Don't bother, do something off-site instead. If you need a fireproof or waterproof NAS you've essentially already lots.
Wouldn’t it make much more sense for the design to mount all the external connection points as high up this tall-ish device as possible.

Maybe it’s just me, but seems like a bit of a design oversight to mount everything at the bottom.

In the event of a flood surrounding a potentially sealed box, having the cables further up might just make all the difference, right?

To safeguard the board, I think you're right.

But from a cursory read, it seems they are mostly interested in ensuring only the spinning disks are safe (the SSDs are outside the sealed box, with the board).

I don't understand how you review a fireproof NAS without putting it in a fire. The one thing I would want to know about a device like this is how effective it is at protecting the drives- find a burn room (I can think of several universities that have them) and chuck it in!
I think they did: there is a mention at the end of the article as how they lost a camera during a test and they are trying to piece together the footage they could salvage.
If they did they should actually mention it in the article- were they able to actually restore and use the drives?
Feels like burying a heatsinked, passively cooled NAS would be more effective if you insist on the backup being on-premises
Any guess at what size that heatsink would have to be to dissipate the heat from the spinning disks and board?
Depends on local soil conditions (type of soil and moisture content). Some soils are much better at conducting heat than others.
