Hitachi and Partners Develop New HDD Technology Providing 8-Fold Density Increase

[theJesus]

I'd like about six of these in RAID 0 for storage

hell no, i've got about 15TB of data and NEED MOAR.

Now, imagine replacing all your drives with just one and still having ~9TB free.

Why not? Ever heard of crystals ? Pretty damn tough and are self arranged materials

Diamonds are the hardest metal known to man.

I am really looking forward to these. I have 1UE rack's running 2.5" drives. Nice, small, cool, quiet. But currently with just two drive bays I'm limited to 2x640GB, and if I RAID 1 then just 640GB. While I am OK with that storage space today (we only use 30% of it on documents, PDFs, etc) it will *not* be enough next year when we intend to store video material too.

Even if we don't go video, then having a SINGLE HDD backup server that can capture everything in the office would be marvelous! There is nothing more time-consuming that managing multiple drives with different backup hypothecations. One drive, snap the office, job done

So long as data integrity is maintained with these new drives, GREAT!

Diamonds are not metals.

Know your meme

Anyway, I will definitely be getting 24TB drives when they're available

FYI In Your Link:
Because diamond is an insulator rather than a conductor of electricity, it is not classified as a metal.

I think you're missing the point

Back to the HDDs please?

 

[Swamp Monster]

Of course, I hope these new HDD's will be avaliable in very near Future, and prices will not make my wallet empty.

 

[theJesus]

I anticipate that I'll be done college by the time the 24TB drives are out, so I'm definitely getting 6

Crickey! Proof that there is a reason we should censor the web! We should issue "licenses" to allow some people to WRITE and POST material! Amazing how we let these things develop. Someone says something stupid, and then it becomes cool to quote this disinformation, and some poor sucker who is hoping to learn, picks up the proverbial wrong end of the stick.

Personally, I disagree with lowering educational and scientific standards to the lowest common denominator, and allowing illeducated memes dominate, confuse, or muddy our thirst for knowledge. (when they are wrong). There are plenty of chat/nonsense sites full of lax editorial and rubbish. Let's stay away from them, and not let them near our beloved TPU.

Very nice and i am sure price be high for a while until others start doing ones with such high density.

Hmmm 8 fold increase in density!! I wonder what kind of real world increase in speed it would gain? 3 fold maybe?

If so they could read/write around 300MB/s which would make ssd almost obsolete if not for the quick access/load times.

It's the sata port whats slowing SSD's down if there was higher speed SATA there would be higher speed SSD's.

And they could do faster SATA ports and controllers but it's all about making money like hell SSD's dont get hot yet .. Worry about SSD's when they have massive heatsinks on them ha.

Here's an idea. I don't need more than 2 tbs. I get a 12-24 tb drive. If I short stroke that down to 2 tbs I should get a significant boost in access time, and better average transfer rates. Still no ssd, but maybe raptor level or lower at only 7200 rpm. An actual raptor using this and short stroked might get down to 4 ms. Right now it's only a neat trick, but if we hit a truly absurd over abundance of storage space I could even imagine a line of performance drives shipping short stroked from the factory.

You can make them small so you can run them at high speed. With this density we can get 1 TB 15000 RPM Raptor drives. Or 2 TB drives in Laptops, super small externals (like 1 and 2 TB drives that are only slightly larger than thumb drives).

This could also help make the Retangular Hard Disk drives more viable since we can keep the current drive sizes, but make the RHD's the size of SSD's.

Wonder what ever happened to the develop of RHD's.

The tech is still be worked out. Their are heat issues and ware issues related to it vibrating in stead of spinning. The last I checked on it, one of the devs. wanted to suspend the internal parts in a liquid. Then everyone got freaked out about it.

 

[Steevo]

I need more room, 3TB with only a few hundred gig left, and I haven't backed up my movies, video, or installed half my games.


I foresee the need for a 10TB server in my immediate future. On Gig network of course.

 

[dr emulator (madmax)]

hell no, i've got about 15TB of data and NEED MOAR.

i've got that many drives i've actually know idea how many drives i have got

actually just think of all the hot gals you could store, mind blowing

 

[WarEagleAU]

Wow, very awesome. Now if they can get them closer to SSD speeds....lol.

 

[LAN_deRf_HA]

For the average person 10% of a 24 tb drive would be enough. Look at the access time on a 10% shortstroked 2tb. Raptor territory.

 

[Wile E]

anybody else think we should slow down, i mean come on, wasnt it just the other day we were astounded by the intro of 1tb, now 3tb, very near to 10tb yeh, but24 ::

No. Not ever. There is never enough storage or speed, EVER.

I want at least 6 of these 24TB drives to put in my server in a RAID 5. That should last me at least until the 100TB or possibly even the 1PB drives release.

It doesn't quite work that way. You are not accounting for the fact that a single accessed sector would contain 8 times the information. In other words, Arel density directly affects throughput as well and storage capacity. Assuming nothing else changes about the drives, seek time would improve some, but once it found the data we are talking about a difference in the amount of available data. A single revolution of a Raptor drive, short stroked or not, will contain X amount of data. The same single revolution of the new density system will contain 8X data. This drastically alters the MB/s.

You can also look at it in this way. Lets say we have a Blu-ray disc (50 GBs) and a DVD (4.7 GB) in identical drive bays, but running at 8x read speed. When then program the system to read 1 GB's of data off the disc and into the system. Assuming both system are exactly the same, the DVD will on have to spin completely around to almost 20% of the disc's surface; however, the Blu-ray will only have to spin around to about 2%. Since they are spinning at the same speed, the Blu-ray will have completed its read long before the DVD has.

This improvement is almost a perfect parallel to Blu-ray except with HDD the systems connected to it have already been proven to be able to handle the increase in data throughput. SATA 6Gb/s is ready and waiting, and Burst Read/Write speeds show HDD's other components to be able to handle more data. While it will not yield a perfect 8 fold improvement in throughput, I personal don't think a 4 or 5 fold throughput improvement is out of the question.

In the end, the only concerns from our stand point is A. the cost of this new polymer and B. time needed to go from where they are now to mass production in place.

He might be implying that the latency on short stroked drives are pretty low as it is (as in his example). Then when you short stroke a 24TB at 10%, you'd get 2.4TB of space with comparable latencies, although the speeds will be significantly higher of course due to the massive increase in areal data density.

So then you'd have a high speed 2.4TB drive with decent latencies (almost comparable to a Raptor probably, given a constant spindle speed again). I'm guessing he meant that such a drive would be plenty for most users.

Of course, short stroking a 24TB to 200GB would maybe give a slight advantage in latencies due to the head only having to move slightly side-to-side to access any given sector, but the limiting factor would always be the spindle speed as you explained in excruciating detail.

Thanks, I just realized that he was talking about access time and not read/write speeds. I have to start doing all this at reasonable times.

 

[BorgOvermind]

Don't worry ... we won't see this tech on the market any time soon. It takes years to develop it up to mass-production status.

 

[MikeMurphy]

They need to develop something better than a read / write heads that moves around. Maybe a head strip across the platter.
