IBM and Fuji Announce Tape Storage Breakthrough
robkill writes "IBM and Fuji have announced a breakthrough in the amount of data that can be stored on magnetic tape, a 15X improvement to 6.67 billion bits of data per square inch. IBM estimates that it will be 5 years before this hits the mass market"
When will tape die?
is a lot of porn.
What?

How long does it take to write this stuff?
And how long to seek?
Because if it isn't faster than swapping old-technology tapes, it's not worth a damn.
I read about it a history book a few years back (right next to zip disks and 8 track players)....
What's next? Commodore 1024?
Here's a better article.. They're claiming 8TB before compression on an LTO-sized tape. Tape record smashed with 8 terabyte format
You've clearly never worked in an enterprise-level environment. Larger companies like WalMart measure their storage requirements in petabytes. To these companies, the physical space required to store tape backups is significant, especially when you consider some records (such as employee records) have to be kept for up to 30 years after the employee leaves the company. Plus, virtually all accounting records must be kept for a large number of years by law.
FYI: Sony claimed 11 billion bits per square inch quite some time ago.
It's always good news when someone figures out how to store more bits into the same amount of space, and I'm sure that companies like IBM and Sony will keep pushing the limits.
Not everyone is a home user. Corporations far more than 26TB of backup tapes, you should see some of the tape libraries I've worked with. Whole rooms full of tapes with automated robots that load and unload them from banks of machines. As for backup speed, tape is not so slow anymore. LTO3 can do over 100MB/second.

If it's for tape, it depends on how long and wide it is. They give the denisty, so you can compute how much a particular tape size would hold... If it is about 6 Gbits per square inch, and is made into half inch tape that is ten feet long, then it'll be about 60 square inches, which is about 45 GBytes. If it is about 750 feet, which seems pretty realistic, then it'd be something like 3 TBytes per tape.
I've probably scrwed up the math, but I'm sure you get the idea.
So if you combine the tape density breakthrough with the Linux device driver breakthrough, can you go faster than the speed of light? Or does SM just need a thesaurus?
-h-
But don't worry, I am sure you know better then the people at IBM, must be why you make billion and they do not advising the biggest companies in the world.
MMO Quests are like orgasms:
You may solo them, I prefer them in a group.
And I'm still waiting for the flat-screen TV you unroll like a poster and tack up with some double-sided tape.
So this IBM announcement fails to excite. Five years is a very long time in the technology industry.

Why yes, I AM a rocket scientist!
All you naysayers, understand that we had exactly the same sort of announcements before the Linear Tape Open (LTO) standard was developed. IBM led a group of manufacturers to develop a standard built around a few breakthroughs in tape density and drive head technologies. They predicted 10X (or more) capacity, 5X (or more) throughput, etc. and it would be available in 5 years or so. Sure enough, LTO-1 came about and immediately led to a tape storage boom. Quantum pushed DLT to about its limits, Storagetek upped the ante with their very high speed formats, etc. Everything got cheaper. Tape stayed relevant. I predict the very same trend in the near future...

I wonder, if the disk sizes will keep the dominance in 5 years. They probably will... Or, a major breakthrough in, say, "flash" storage technology will make all other media obsolete...

Is the value of your data that cheap? If so, hdd's may be just the thing for you. The three variables in play are for data backup & restore are: Fast, Reliable & Cheap. Pick any two.

Upgraded YOUR tape drive lately? DDS has to be the slowest "modern" tape formats in existence. I'll never touch one of those drives again. Worthless. Try VXA-2 or M2.

DLT tape cartridge was 0.5 in x 1700 ft, or 10,000 square inches.
At 0.75 Gbyte/sq in, that's 7.5 Tbyte per tape. That's a lot.

I have a 400GB Seagate SATA hard drive and it gets no where near 100MB/s, what kind of hard drive are you planning on using?
In my experience, the trouble is not in writing lots of data to tape, it's in reading it successfully afterwards. /only half-joking
Recursive: Adj. See Recursive.
In the 1950's, data was recorded on 7-track tapes at 200 bits per inch. Those 7 tracks recorded 6-bit characters (EBCDIC?) with one bit of parity. A 2400 foot tape might hold some 5 million characters (upper case only, please). By the mid 1960's tape densities more than doubled to 556 bpi.
Sorting algorithms were written to sort information using mag tapes; the speediest would make the tape vibrate in the vacuum columns with a minimum of reel-to-reel motion.
By the 1970's, most shops changed to 800bpi, 9-track tapes, which would happily handle 8-track encoding. Then came 1600 bits per inch -- you could store an amazing 50 megabytes onto a single tape.
There was a constant temptation to compress data so as to stuff as much onto the tape as possible. As a result, many graduate students earned their assistantships by decoding tapes written with oddball parity, density, and encoding combinations.
The scattering matrices from my dissertation are encoded onto 9-track 1600 bpi tapes, carefully stored in my climate uncontrolled attic.
I need it for all the pictures of your mom.
Yo momma so fat, I need all that storage for just one picture of her.
VXA-2 ist biggest piece of shit technology i've ever encountered.
We normally use LTO Tapes (mostly 1 and 2), but some customers wanted a "budget" solution. So they got VXA-2 Tapedrives from IBM.
Some points:
* They are slow, and i mean real slow. 250-300mb/min slow
* The tapes look like they are gonna break if i look at them, no comparison to LTO Tapes which look sturdy
* The loading mechanism sucks, and also look liks it's going to break
* Two of those VXA-2 Tapedrives actually broke after 2-3 Months in use. Yeah, got replaced in 4 hours, but it sucks nonetheless
* The tapes are EXPENSIVE. Cost more than an LTO2 Tape without even half the capacity
Or, in short:
Never buy VXA-2. Buy LTO1 or LTO2. If you can afford it, LTO3.
