Seagate Announces 12 TB HDD: 2nd-Gen Helium-Filled HDD

sounded good, and got depressed from the Australia Tax. US$59, but AU$100.

AU$100 - $10 = $90 (ish) as taxes are built into our prices, not added later

90 Australian play dollars = 69 American real dollars

US$69 - $59 US price = Australia Tax of ~US$10, approx 16%.

edit: I wonder if Amazon goal with this was to get their hands on as many photos with their full metadata as possible (for training).

On the other hand, 1GB is pretty tight. I suspect there's a lot of people who could come up with 1GB of photos they don't care to part with, and coming up with 1GB of valuable home videos is child's play, even assuming efficient encodings of the video rather than the rather flabby stuff that tends to come straight out of consumer cameras or phones.

But I bet if most people had to fit the Family Jewels into 10GB, they could, just one more order of magnitude away. Of course HN will have a way-above-average number of people who have way-above-average video recordings and such. Or, perhaps more realistically, call it a single 32GB SD card. At the moment my "family jewels" clocks in at about 90GB, however, that is with no judgment whatsoever about what photos we keep and with a lot of the aforementioned "flabby" videos, not to mention, no judgment whatsoever about what videos we're keeping either.

It mostly comes down to how many photos you take, really.

Personally I have close to 7TB of backups and personal video footage stored, everything encrypted, never had any issues.

However there's always the danger of them pulling a onedrive at some point in the future and reverting from unlimited back to something like 1TB if people actually use it.

No. Helium hard drives are laser-welded shut. See http://www.seagate.com/files/www-content/product-content/ent... for the details about what parts are made out of what and the basic details of fabrication.

Back in the stone age disks were "fast" in random access but they couldn't hold as much as tape could. So to get the storage you had a mix of disk and tape. That started as you had a command you would send to the operator (another historical concept) which was the person who was responsible for 'operating' the computer. That would print a message on a hard copy terminal that would say "Load Tape XYZ on Drive 2" or something similar, the Operator would go to the shelf of tapes, pull out the one that was labeled XYZ and put it on drive 2, "mount it" (which would, on vacuum readers, suck in and tension the tape and read the first block (the label)) and make it available to the operator who could verify it was XYZ and then send pack (again on the console) "tape loaded." Then your batch program would start and you'd get the classic video of a computer with the tape being read in bits and bursts and often another tape being written in bits and bursts.

Computers got bigger (able to process more data) and tape libraries got bigger, one of Sun's big customers was Fingerhut (mail order catalog) in Minnesota and they had a room where there were lots of 'tape operators' and when a customer was on the phone and the operator said "let me bring up your account" it lit a sign in the tape room with the needed tape, someone would jump up and grab it and put it on the nearest tape drive and 'tag' (there was a clock showing time from request to mount) and the tape would identify itself and send the customer record to a disk so that they were "online" and the operator's screen would light up with all the customer details.

IBM and StorageTek made robotic libraries that did the same thing, but without the human in the loop.

Then in the early 2000's NetApp and other storage vendors started offering ATA disk drives (dense, cheap) as storage offerings and slowly, eventually the tape libraries were crushed because this dense storage was more cost effective.

Primary disk storage has now gone over to solid state disks. They have even better random access and generally and do reads at the limits of the interface they are attached to.

But there is still a market for dense, cheap, read mostly data stores. That which used to be tapes, then tape libraries, and now spinning rust in a bath of helium. A typical SATA drive can really only do about 110 "IOPS" per second, in a large part because the mechanics of moving things around is inviolate.

So the use for dense data stores behind a small i/o pipe is read mostly archival and reference data. Oil & Gas sonar dumps, credit card sales transactions, backups of data which is 'live' elsewhere, etc. The role that Tape used to play but no longer does very well.

the use cases for raid5 have pretty much been replaced with raid6 plus hotspare.

(Though probably something with checksums instead of naked redundancy.)

If all you need are two hard disks, go for it.

That's how markets work.

We will need something because fossil fuels are not sustainable. In 100 years we should be pumping much less oil than we do today. This also means finding substitutes for all of the byproducts of oil production.
