400 TB Storage Drives In Our Future: Fujifilm (anandtech.com) 51
One of the two leading manufacturers of tape cartridge storage, FujiFilm, claims that they have a technology roadmap through to 2030 which builds on the current magnetic tape paradigm to enable 400 TB per tape. AnandTech reports: As reported by Chris Mellor of Blocks and Files, Fujifilm points to using Strontium Ferrite grains in order to enable an areal data density on tape of 224 Gbit-per-square-inch, which would enable 400 TB drives. IBM and Sony have already demonstrated 201 Gbit-per-square-inch technology in 2017, with a potential release of the technology for high volume production in 2026. Current drives are over an order of magnitude smaller, at 8 Gbit-per-square-inch, however the delay between research and mass production is quite significant.
Strontium Ferrite would replace Barium Ferrite in current LTO cartridges. Strontium sits on a row above Barium in the periodic table, indicating a much smaller atom. This enables for much smaller particles to be placed into tracks, and thankfully according to Fujifilm, Strontium Ferrite exhibits properties along the same lines as Barium Ferrite, but moreso, enabling higher performance while simultaneously increasing particle density. [...] Fujifilm states that 400 TB is the limit of Strontium Ferrite, indicating that new materials would be needed to go beyond. That said, we are talking about only 224 Gbit-per-square-inch for storage, which compared to mechanical hard disks going beyhind 1000 Gbit-per-square-inch today, there would appear to be plenty of room at the top if the technologies could converge.

LTO is going strong. Your point is why LTO cartridges are designed to never expose any part of the tape to open air.
Personally, I recommend making 2 backups of anything important when using tape.

Professional tape is actually both more reliable than disk (if used properly) and has vastly more reserve S/N rate for data recovery.

You can have the backup program write out two copies at once. Ideally, you back your stuff to a SSD cached hard drive array, so the backup windows are quick. From there, copy from the drives to tape, and doing two copies is pretty quick. That way, you can take one copy and send it offsite, and keep the other in the safe.

ok but on one scratch in the tape you'll loose even more data.
who is still using that?
People that (unlike you) actually understand the technology. These can pretty much be recovered as long as the whole tape is there and it is not too badly mangled.

I have used tens of thousands of LTO tapes. I have had three tapes go bad with soft errors. I never had a single tape that was so bad that I had hard errors when pulling data from it. LTO is archival grade, while HDDs and SSDs are not.
Yes, tape may sound not as snazzy as storing it in the cloud, but it is a lot harder for a bad guy to zap a stack of tapes physically in a safe than to destroy one's S3 buckets and Glacier vaults with a few mouse clicks.

I'm feel like Ethernet is not going to cut it. Might as well have a local tape head at each workstation, with the tape running alongside the twisted pair to the storage bunker. Heck, we could replace the LAN with a tape loop altogether -- if a machine crashes, the backup is right there.
Latency might be a slight problem for FPS games and commenting on a TikTok video before it finishes, but it might give way to a healthier online culture.

Current LTO-8 tapes hold 12 TB uncompressed and transfer at 360 MB/sec, taking about 9 hours to write all 12 TB in one go.
For comparison LTO-7 holds 6 TB but took about 5.5 hours.
The write speeds were fairly close, but with twice the capacity in LTO-8, it still took less than twice as long, so it isn't a linear change in time.
But these types of drives are used under different presumptions than normal disk based storage.
Backups are made in different tiers using different media appropriate for each tier.

Back in the 90's I had tape drives. They'd inevitably wear out or stop working, then you go get another one, and find out that it won't read the tapes you laboriously backed up important stuff onto. Hundreds and hundreds of dollars invested in junk that ended up in the dumpster. Nope, not again.

That's the whole raison d'être of the LTO standard [wikipedia.org].
People got fed up with the 90s' proprietary crap, and started using standards in the 00s.
You can buy any drive from any manufacturer and it could read the tape of any other manufacturer, as long as they follow the LTO standard (as opposed to propreitary format like DLT).
Not only that but the compatibility of the generations of hardware is also specified:
- a drive can also also write on last gen's tape in their native format: this year's upcoming LTO-9 drive will be guaranteed by the standard to be able to write on LTO-8 tape
- a drive can read two generations back LTO-7 drives could read as far back as LOT-5 drives
(The only excetion: LTO-8 cannot read LTO-6)
Had you been using tape nowadays, you wouldn't have had the "new drive doesn't read the previous backup" situation.

For home use and even small offices, spinning rust HDD are already good enough:

That's because the compatibility was assured only by the manufacturer. They're more careful with LTO because they're commonly used by enterprises who have more lawyers than the drive manufacturer has employees.

That sounds like someone who was burnt by DAT. Shitty standard that was notorious for not reading tapes written on other drives even from the same manufacturer. Alternatives at the time like 8mm and DLT didn't suffer from the same problem. LTO certainly does not suffer from the same problem.

You misunderstand: I'd buy a 'compatible' tape drive, and it wouldn't read the tapes I'd made with another drive.
You misunderstood what I'm trying to say: I'm *absolutely not* thinking you're an idiot who tries to put DAT in a DLC drive.
Again this "in between quote 'compatible'" situation is what LTO was born to address.
With QIC minicartridge and Travan, you could be being the exact same drive from the same manufacturer, but due to difference in the version of the software packaged in (Hello, different revision of Iomega's backup software!) or other invisible differences (differences of firmware? minor hardware diffe
