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).

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.
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. :)
I remember hearing that back in the mid-80's. May I introduce you to bubble memory?

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.
I am sorry, when is 100 TB more than 90949 TB?

For some reason extrapolating exponential growth is very popular in certain circles. I assume that's because it detracts from other areas of exponential growth, like total population, energy consumption and CO2 emissions. Singularity, here we come!

You talking about 110 GHz networking, or the prediction that the singularity would occur in January 2012?
Il n'y a pas de Planet B.
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.
They need to delete those emails because they don't want people to see them.
Each employee won't generate 100 KB of emails per day. Deduplication and compression on the back end will shrink that massively. The more employees and emails you throw at it the more effective it becomes because we all tend to say the same shit over and over.
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!

The good news is that population appears to only go through a phase of exponential growth before naturally settling down. Something about a developed society really depresses birth rates. A few extreme cases have required the use of coercive population control to get through the developing phase, but even China is now in the process of gradually eliminating it as no longer nessicary.
Johnny Five had a storage capacity of 400MB. More than enough to digest the entire contents of a library and still wanting more. Yes, even with that, they somehow managed to add a lightning strike, simmer and add emotional responses and have space to spare. I can't find a decent OS with voice recognition out of the box (never mind a heuristic analysis and response) that takes less than 20GB in the initial install!

Not really. There are a couple of developed nations that still have a high birth rate which shows that reduced fertility is not an automatic byproduct of developmnt. The current UN forecast is 11 billion in the early 22nd century. I think mother nature will have something to say about that.

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.
Because the cost of a drive to a company is somehow many hundreds of times what it is to you and me. My company measures the cost of disk at $10,000 per terabyte, whereas I can get a 3 Terabyte drive for less than $100.
My company has 60 employees and they have a 1 GB limit on e-mail accounts. I'm not sure they still manufacture drives small enough to where that is a valid limitation.
They also encourage you to back up your data, and provider a shared drive amongst all users which has a total size of 40 GB. Most of our laptops have 1 to 2 TB drives.
If you are not allowed to question your government then the government has answered your question.
400 MB is enough to store a library. The problem is, a picture is worth a thousand words, but it takes the space of 100,000. And a video takes the space of 10 or 20 pictures per second of video.
Pictures and video is what a lot of the large drives are being used to store.

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.
(shrugs) your IT is definitely stuck in the 2000s (i.e. 5+ years ago).
Cost per TB (raw storage, the hardware to hold the storage, plus the backup tapes / disks) for bulk storage - is definitely more like $800-$1000 per TB these days and not $10k. The sweet spot for bulk storage these days is the 3TB 3.5" enterprise SATA drives at about $230 each. Add in the loss of capacity due to RAID + server costs and you're at about $500/TB of actual storage.
Primary storage is still much more expensive at $1500-$2000 per TB. But primary storage is using SSDs (around $1/GB) or 15k SAS drives (about $0.35/GB to $0.50/GB). And not the relatively inexpensive 3TB enterprise drives at $0.08/GB.
