That feels like a dream job for a temporary amount of time. And very effective too. I assume the VFX studio is in Melbourne?

Dream job to spend hours and hours in a plane? Then more hours clearing customs? Thanks but no thanks.

But Americans going to Australia just pass through a computerized system. You don't even have to talk to anyone.

I agree with OP, if this was a first class flight, it wouldn't be a bad gig.

"Let me just surveillance out for a second" Guess where this will have the biggest impact in the next decade - the long term storage of billions of personally invading surveillance data points forever... Seriously, this tech will be abused. Against everyone. Facial recognition much? Zoom data? TikTok Data in a very compact physical form-factor? Utah and China will LOVE this!

Can someone explain the Utah reference?

That's a great effort in technology and it is remarkable. I have some doubt about the real benefits that are beyond the technology though.

First of all about the security of this system. Yes, it is very avantgarde but being a physical support I will always have the worry that it can be damaged.

If I immagine to use it to store sensitive information this worry rise up. It can easily be accessed or stolen or damaged.

And what about the possible cost of a solution like this?

a part from this aspect it is incredible what Fujifilm has been able to reach in terms of tech

Current LTO-9 tapes can store 18TB and the LTO roadmap doubles capacity about every 3 years. So this tape tech would be on the same scale as we might expect LTO-14 to offer in 2035.

So unless this is an incredibly radical breakthrough, that’s the timeframe I’d expect for the headline to become a real product.

Note that the article shows a table from IBM claiming they achieved 35TB-per-cartridge capacity in 2010, and that still isn’t something you can buy.

In English, when purchasing on behalf of a corporation, “we” would almost always be used. “we” is even frequently employed by auctors writing papers to depersonalize.

I guess it’s just me then. I wouldn’t write “we” in a comment online without explaining who “we” is, it seems like an unnecessary detail to explain

That’s how I meant it. Seems odd to say “we” out of context like that. And anyway I would be the person purchasing so including the whole company is.. odd.

Anyway, I guess this is the pedantry we (!) should expect from HN

Time for the ever golden quote: Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway. https://en.wikiquote.org/wiki/Andrew_S._Tanenbaum

When I was working in vfx we employed a guy who's sole job was to fly back and forth from LA to Melbourne with pelican cases full of hard drives. It was faster and more secure since we were working on air gapped networks.

I wonder if tapes are more prone to some form of driveby attack, whereby instead of requiring physical or remote access to a location, a strong enough magnetic field within a certain distance of a datacentre could penetrate bricks and mortar and render them useless

I'm envisioning a huge device in the back of a van which pulses a powerful beam, similar to typical movies (Oceans 11?) cutting the power to a bank / casino prior to a raid

If your drive uses ZFS you apparently need to power it on more regularly than that to avoid bit rot.

Why would the file system affect bit rot rate?

It doesn't. What matters is that you have a filesystem that can detect and repair bitrot. For that to work, it needs to check everything occasionally, which means they need to be powered up occasionally.

If you don't do that, eventually you'll get to a point where it can't repair anything, and then you gain nothing over using a filesystem that doesn't do this, is the point.

Why do LTO manufacturers always quote compressed sizes, like we’re in the days of stacker?

> Data on the tape is stored at a record-breaking density of 317 gigabytes per square inch Me wondering about those micro SD cards that can store 1Tb.

Those SD cards aren't close to a single layer, so it's not really equivalent. Ad absurdum, stacking two Micro SD cards on top of one another hasn't just doubled your density even though surface area is unchanged.

We reached an inflection 'amazing!' point when we are able to put '100 songs in your pocket'. That was really a shocking thing given the limitations of CD/Tape etc.. But the real inflection point may come when 'all relevant information in your local disk'. The tapes here in question can maybe store every book every written! We may be able to put the entirety of Wikipedia, every film, TV Show ever made, every book eve…

Copyright is a barrier to that.
