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.

Missing TB mate ;)
I read it and thought the sentance was talking about 2.5inch and was like wtf :laugh:
I'd be more impressed with a cheap and fast 1TB SSD by late 2009/early 2010...
I predict... 10TB?
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.
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.
