IBM and Sony Cram Up To 330 Terabytes Into Tiny Tape Cartridge (arstechnica.co.uk) 71
IBM and Sony have developed a new magnetic tape system capable of storing 201 gigabits of data per square inch, for a max theoretical capacity of 330 terabytes in a single palm-sized cartridge. From a report: To achieve such a dramatic increase in areal density, Sony and IBM tackled different parts of the problem: Sony developed a new type of tape that has a higher density of magnetic recording sites, and IBM Research worked on new heads and signal processing tech to actually read and extract data from those nanometre-long patches of magnetism. Sony's new tape is underpinned by two novel technologies: an improved built-in lubricant layer, which keeps it running smoothly through the machine, and a new type of magnetic layer. Usually, a tape's magnetic layer is applied in liquid form, kind of like paint -- which is one of the reasons that magnetic tape is so cheap and easy to produce in huge quantities. In this case, Sony has instead used sputter deposition, a mature technique that has been used by the semiconductor and hard drive industries for decades to lay down thin films.

Putting a few of their numbers together seems to imply a read bandwidth of 24 Tbps (330 terabytes = 330*8 terabits/tape, tape length = 1098 meters => 2.4 terabits/meter, tape speed = 10 m/s => 24 Tb/s). Which to me is way more interesting than the total storage size. Of course I have no idea what you could actually feed that into, it far exceeds CPU memory bandwidth, let alone SCSI or PCIE. Do these things not actually run at full speed for more than a fraction of a second?

This would solve a ton of storage/backup issues. A lot of people don't have the network connection to make cloud backups (much less complete disaster recoveries) feasible.

There are tons of high capacity optical offerings available (Sony has some)... but other than specialty markets, they are not worth it. What would be nice would be a tape or even an optical drive for backups.
Optical wouldn't be bad either. 400 CD jukeboxes are a solved problem, so having a BD-like format with 2-3 terabytes per disk would solve a lot of backup problems, especially with WORM capability to fend off ransomware.

If you think optical is any good whatsoever for archiving, you have never wasted time on it, No two optical drives can even agree on whether a written media can be read. Even the original drive is likely to reject a disk it wrote itself the day before. It is garbage technology on which I wasted all kinds of time and money, only to find it to have a reliability of zero. You can't have recording surfaces exposed to fingerprints and dust like that if you want something to depend on.

The only real option for most normal people is to just build a backup server with another array to hold the backups. Even ignoring media archives, personal data with photos, videos, etc. can easily approach 1TB. I just upgraded my main server, and used the old one with some of the old 2TB drives in 3-way mirrors as the backups. I'll likely move it offsite now that it's synced up.
An affordable tape system would be great, but I have yet to find one that has a reasonable cost with better reliability than my HDD arrays, even though they require a little more maintenance. Disk will always be faster for random I/O, but tape would be great for a lot of stuff if the cost were somewhat reasonable.
And $1000 won't do it. People won't buy it. A few people on /. might, but your average person? No way in hell. Not with 4TB HDDs under $100. $200 drives with $20 tapes might work, but they would need to be in the TB range, native. I don't see that happening, though I'd love to be wrong.

Agreed as to price range. And you're not wrong; it's not going to happen. It's friggin' IBM and Sony. That's practically synonymous with overpriced crap. IBM will only want to sell them with $10,000/year service contracts, and Sony will only want to sell them for $10/gig. They want to pay back the R&D after one sale. No way these drives will ever be reasonable for even medium sized enterprises, nevermind consumers.

HDD is only reliable if it's spinning and in an array that's scrubbing once a month. Otherwise a single disk fails at p=0.02 per year, which makes it impossible to bulid a large reliable offline library. LTO is enough more reliable that, using the same number of parity tapes, it can be scrubbed much less often while achieving a given size & reliability compared to a disk array.
This is an important archival characteristic. It takes a lot of infrastructure to keep a disk array scrubbing: electricity,

The question is what do you want to do and how much space you need. If you're looking for an onsite backup, then for $1000 you can build/buy a RAID server that will handle terabytes of files.

Longer archival life for the media is irrelevant if the drive becomes obsolete, as is the case with today's tapes. LTO, for example, only guarantees backwards compatibility for two generations, which come every 2-3 years. The typical consumer isn't going to put in the time to migrate archives to the current format before old drives stop being available.
If you think $1000 is a reasonable investment, might as well buy a new $100 hard drive every two years. Interface compatibility will be vastly easier to ensu

This is an accident waiting to happen. Every vendor implements encryption as they see fit, usually storing keys on either an EEPROM, flash, or battery-backed RAM -- or if you're lucky, some unused or segregated part of the tape (might waste a few blocks but that's OK).
