2.5 TB HDD a Reality by Late 2009

TDK Japan, a supplier of read-write heads for hard-drive manufacturers predicts that 2.5 hard drives will be a reality by late 2009, and will reach markets by early 2010. The company presented a roadmap to the press late last week, that shows that it will have the technology available to produce 3.5 inch disk platters with 640 GB data density. Four such platters will go into making 2.5 TB drives. On the 2.5 inch drive front, the roadmap shows a jump to 320 GB per platter density, which allows 640GB 2-platter SFF drives to be announced by manufacturers towards the end of this year.

Hard Drive manufacturers had reached the 2 TB milestone earlier this year. Seagate and Western Digital used four 500 GB platters in their products. At this rate of data density increases, a 5 TB hard drive in 2010, as predicted by Hitachi's Yoshihiro Shiroishi last year, sounds a little more realistic.Source: Register Hardware

Awesome - as long as the only drives at that capacity aren't the slow-as WD green series. Gimme a samsung spinpoint/seagate/WD black 2.5TB drive and i'll be a very happy man.

Missing TB mate ;)
I read it and thought the sentance was talking about 2.5inch and was like wtf :laugh:

its no surprise, they just need to slap another platter in really.

Eh. Let mechanical HDDs die.

I'd be more impressed with a cheap and fast 1TB SSD by late 2009/early 2010...

I have little interest in a 2.5TB HDD over a 2.0TB HDD except for the pressure it puts on 2.0TB prices. :)

These drives are mostly for storage, average performance is just fine for that.

That's one solution. Though TDK increased density here. I do wonder why they don't make higher drives with more platters, or 5,25" ones, like the Bigfoots (which were quite unreliable :)) back in the days. I believe the market is there.

I wonder how big mechanical hard drives will get before SSD's fully take over.

I predict... 10TB?

SSD's are doubling every year, if not more.

HDDs are increasing about 50% a year - with setbacks (for example, the latest large drives are all 5,400 RPM)


largest commercially viable right now SSD is 512GB, within a year that should be 2TB or more - while mechanical drives will be around the 3-3.5TB mark.

Give it another year after that, and we'll be close. mechanical drives will still have the better pricing at this point.

1-2 years after that, SSDs will dominate.




The simple fact is, SSD's are still 2.5" - once they're cheaper they can slap them in a 3.5" enclosure, quadruple the size and call it a day.

Prediction? I think we will see "performance" HDDs die out. They cant compete with SDD. And at slower speeds, HDDs can store at higher density at lower power.

Next step? 4500rpm 5TB HDD 3.5" format. With slower read/write speeds. Whereas SSD will get faster, and the standard size will become 320MB rather than 80/160 as it is now.

10TB? While in theory you could manuf. a double height drive like the old SCSI drives... due to manuf. and reliability costs (they were horribly unreliable and prone to damage from small knocks)... more likely peeps will just RAID array them.

Don't hold your breath waiting for that to happen.... :(

...and much like Intel sticking two Pentium 4's into one chip to keep up with AMD, we'll probably see double-height mechanical drives. They'll have to. :laugh:

Bow before the God's of the Gigabyte Age. The Megabyte's feeble Demi-Gods are no match for my platters!

wrong generation. this is the terabyte age.

isn't there a limit to the density of the process they currently use on HDD? i can't recall what limit i read but it wasn't too high in the T, like 5 or seomthing. could be wrong. i also read that they may take a route of using multi faced disc's as well as multi heads for faster read times and double the memory space per platter. could be wrong and i doubt we'll see this since SDD is going to take hold.

I'm betting on Petabyte drives before mechanical drives are historical.

i'll take you up on that, $10 USD?

Only if some other method for storing data on mechanical platters is developed -- there's a physical limit to it, and it's far, far short of a petabyte right now.

yep, something with how small the magnetic particles get or something and room temperature will mess it up due to the size. course previous estimated limits have already been broken so i'm sure something will be thought up to continue HDD size, course as i said i'm betting SDD becomes mainstream before that happens
