Consortium Roadmap Shows 100TB Hard Drives Possible By 2025
Lucas123 writes An industry consortium made up by leading hard disk drive manufacturers shows they expect the areal density of platters to reach 10 terabits per square inch by 2025, which is more than 10 times what it is today. At that density, hard disk drives could conceivably hold up to 100TB of data. Key to achieving greater bit density is Heat-Assisted Magnetic Recording (HAMR) and Bit Patterned Media Recording (BPMR). While both HAMR and BPMR will increase density, the combination of both technologies in 2021 will drive it to the 10Tbpsi level, according to the Advanced Storage Technology Consortium (ASTC).
Clearly now that we have 3D printed a piece of cake frosting in free fall, we will 3D print any kind of technology at home in our living rooms.

MTBF and transfer rate numbers are boring... but those can be just as important, if not more, than the drive's capacity.
With high capacity tier 3 drives, one reason that RAID 6 (or a RAID 50 setup with tiers/groups of disks) is used is because it can take days to rebuild a blown drive. If drives continue to have larger capacities, but I/O stays the same, then we will need to add more parity drives to RAID arrays to support multiple drive failures and still keep the data accessible, better algorithms that run in the background to detect (and fix) bit rot, and bigger/smarter caches.
Maybe this is just me, but I'd rather see drives with double the MTBF than double the capacity. I can always add more drives and arrays. A failed disk will cost time no matter what, even if it is just walking to the server room, pulling it out and replacing it with a spare. For non-enterprise customers, a failed drive can be catastrophic since not many users have RAID arrays for protection.
by then... we should be augmented... according to Deus Ex HR
I got first post bitches!
I always figured magneto-optical discs would be a good candidate for packaging in a higher precision drive. Looks like that's on it's way. :)
Surely in another 11 years we'll have a newer tech and the de facto standard will be SSDs. HDD are only king for storage due to their pricing once SSDs match them for GB we'll start to see much larger capacities rendering HDDs obsolete.
We need to cascade memos about our homogenised administrative processing. Forward-looking companies invest in 21st Century management projections.The consultants recommend balanced logistical alignment.
A hard drive to hold all my p0rn!
I'll take this prediction with a grain of salt... http://classic.slashdot.org/st...
So lets say 100k employees, making 100k of emails a day each, that's 3.7 terrabytes per year, so this would hold the CIAs emails for 25 years?
So tell me again why the CIA and homeland security needs to delete all its all emails from the the early 2000s to "save space"?

Yet the NSA builds a new storage facility in the Petabyte class, (approaching Exobyte numbers) in Utah and has plans for 6 others!
Why are such large drives necessary? Is not all data moving to The Cloud (c) ?
He states he has a memory capacity of eight hundred quadrillion bits (TNG: Measure of a Man).
(((((800x10^15 bits) / 8bytes) / 1024kb) / 1024mb) / 1024gb) / 1024/tb) = 90949.47 TB

Why is all the good stuff already modded 5, when I have mod points?
I remember 1GB drive going for ~$100 in 1998. 1TB drives have been under $100 for a few years. We will probably see 1PB drives by 2025

2 types of drives for the foreseeable future.... SSD main drive for the OS and programs, HDD for storing pron. Better get used to it.
Here is my desktop setup:
- One fast SSD main drive
- One 3 TB HDD for video/picture/mp3/document storage
- Second 3TB HDD, gets synched to the first HDD nightly as a backup
SSD gets a manual disk image stored on the first HDD once in a while.
I feel pretty good with this setup, as I'm protected from any single drive failure. Also I have some accidental deletion/corruption protection as the two HDDs are not mirrored in real time.

100 TB is an incredible amount of porn! All slashdotters will want this!
In a few more years, everybody will have enough data space in a laptop to store the whole humanity data (as long as it's not recursive). The Internet in a cache...
Slashdot, fix the reply notifications... You won't get away with it...
interesting that these density improvements could both be applied to tape as well.
yeah, "tape yuck", but it makes a certain amount of sense for cool data. which we have lots of, always increasing. tape seeks are a minute or so, and if density is competitive, tape has a good chance to beat disks on price. certainly on power. the real problem is that the tape industry seems to be sort of demographically challenged...
So what happened to shingled, is it dead?
When all you have is a hammer, every problem starts to look like a thumb.
I think you're neglecting the fact that with larger storage capacities come new options.
Sure, right now you see a lot of people with a 1TB drive that's not nearly full. But I also see quite a few people who fill up really large amounts of drive space with photo, music and video libraries. With enough cheap storage, more people can store music in an uncompressed, lossless format (like FLAC) instead of compromising sound quality with MP3 or AAC just to save space. Digital cameras have gone from 1 or 2 megapixel to 14-18 megapixel in many cases, generating much larger image files for still photos, too. And even your commercial video games are taking up exponentially more drive space than they used to, as developers decide to tell stories with full-screen hi-res video, vs. scrolling a few lines of text up a screen to summarize things, and as they build large 3D worlds you can run around in and fully explore.
Another culprit for sucking up disk space in a corporate setting is DropBox. Companies using the paid "Teams" version wind up with everyone's copy of the software downloading and syncing ALL of the content stored in the shared folders. So instead of just keeping YOUR data, you now have a copy of the whole team/division/company's data you're all storing there. (Yes, you can use "selective sync" to trim this back down. But except for folders you know you have no use for at all, it's preferable to sync it all so you have immediate access to anything your co-workers intended to make available, even if you're not by an Internet connection.)
Somewhat off topic, but while we're talking about drives:
We put millions of transistors on a chip. Millions of photodetectors (pixels) in your phone's camera, a million pixels on it's display. Yet our hard drives have ONE sensor that swings back and forth on a mechanical arm?!?! Why the heck isn't the read/write head a strip, with a few thousand "pixels", so it can read any sector as the platter spins beneath it, without swinging the heads back and forth? That would eliminate seek time.
If needed, you could move the strip back and forth a thousandth of an inch to align a head with one of it's four tracks. That'd be a lot quicker that moving the head a full inch as they do now.
So presumably there is some good reason that can't be done. Still, an additional arm exactly like the existing one, but on the opposite side of the platter, would cut rotational latency in half and increase throughout up to 100%. Seems like an easy win.
Will SSDs with bullt-in flux capacitors be available by 2025?
Cheap $300 laptops these days slap in a 500GB HDD to satisfy the requirement of a hard drive. A basic 500GB disk is what they can source cheaply and easily from the market. However, I suspect that they could ship a smaller capacity disk as well, if that allows the manufacturer to shave off some of the laptop's price. What follows is, that I also suspect that when making a 128 GB SSD becomes cheaper to manufacture than a mechanical HDD, many low-end laptops will move to the SSD format.

"But it's to protect the children!" Bullshit, try shutting down the child traffickers accounts on facebook and ban advertising for foster carers for financial incentives - in fact, ban financial incentives for looking after other peoples' kids and instead try helping the families instead of making shit up about them. The best place for a child is with the family he was born into, NO EXCEPTIONS. If his entire family is dead, THEN you can talk about adoption, otherwise it's not adoption, it's trafficking.
"But it costs the artists money!" Bullshit, musicians don't make anything on CD sales (the last person who did died of a drug overdose, his name was Michael Jackson and he sold millions of records - not even the Beatles made money selling records until after they split up and Lennon got his face shot off). Musicians make money on concert footfall, and then they're paying royalties to their LABELS. Actors and filmmakers are paid in advance of publication, and their contracts stipulate no royalties - only the producer gets any royalties since it was he who stumped up the capital for the project in the first place!

At that density, hard disk drives could conceivably hold up to 100TB of data.
100TB, that is a LOT of porn.
it`s a brave new world we live in, a brave new world
The average new computer being sold today sits on a desk in an office or is a facebook machine at home. It will have in it 500GB to 1TB of storage on average ? Then whats the actual usage, 20% or less ? I have people asking me all the time, my computer is slow do I have too many pictures on it ? I look at their drive, 482GB capacity, 404GB free.
Sure there are some users who have hundreds of movies stored on their computer and businesses and datacenters who would love a drive like that but by number of computers, thats a small percentage. A majority of computers would do much better with just a SSD 1/4 the size of the HDD they currently have. A faster system overall, bootup times cut by 60%, 20-30 minutes more battery life in laptops....
We'll all be able to store all our "home movies" and photos on one drive!
To increase tenfold in 11 years, the Kryder rate https://en.wikipedia.org/wiki/... would have to jump from 15%/year to 23%/year. While this is not fundamentally impossible, in an era of diminishing revenue for magnetic storage I can't see it happening.
Oh, I'm sorry sir, I thought you were referring to me, Mr. Wensleydale.
I boot from the cloud.
This cache and especially native command queuing (ncq), the drive ALREADY has to pay attention to the sequence in which operations are carried out. A read requested first, then a write, might already be done in reverse order, requiring a check that the sector read isn't the same one written.
I don't see any reason reading and writing two sectors at a time makes any fundamental difference.
Another culprit for sucking up disk space in a corporate setting is DropBox. Companies using the paid "Teams" version wind up with everyone's copy of the software downloading and syncing ALL of the content stored in the shared folders.
Why do anyone bother using dropbox like this? In a 'corporate setting' no less? Never heard of "file servers?"
Dropbox can be useful for sharing some files with family or friends that can't use sshfs or a webserver of their own. But a corporation should be able to set up a simple file server, no need to store the same shit on everybody's computers. (And if they need access out of office - a VPN will do that in a safer manner than dropbox.)
Even 20 TB disks in a desktop will shift the balance of data storage from the cloud to the disk. The cloud becomes backup, and that brings up another issue...efficient and reliable restore. Backup we got. Restore at even 1 TB? GOTCHA.
