4 TB drives by 2011

This is a blatent lie

'Current hard disks can store about 200 gigabits of information per square inch (6.4sqcms) while Hitachi believes its new technology means it can store up to 1 terabit of data per square inch.'

Yeh, maybe current harddrives 4 and a half years ago. The article says 15.10.07 though

I expect by 2010 we will start seeing the first 4TB drives

edit -if that was the case by 2011 we would only expect to see 800GB drives
 
That long?, 4 years to just increase to 4 TB?
Meh, expected them in 2 years at most. In 4 years I'd expect 15-20 TB hdd's.

Sorry, but am I missing something here.

All they have done is show a prototype head smaller than ones currently in Hard Drives.

They haven't read any data from a test drive with it, they haven't written any data and from what I can see in other articles - they haven't even proved it can do anything.

They 'believe' it can read/write data at areal densities of 500GB to 1Terrabyte - but have yet to show a reliable model or method of moving the actual head to a position (track and sector) smaller than the actual read/write head. As well as that, they haven't stated what speed it can operate at or how well it handles drive errors or crosstalk. Stating it 'might' be possible to write 1TB to a drive is all well and good - Its quite possible you 'might' be able to write 100TB - but you aren't explaining how small the atoms have to be - how the magnetized atoms affect ajacent tracks and how difficult it is to actually get you head to stay on that track.

Unless they can prove the technology works in real world applications - Like Seagate did with TMR heads in 2005 or consumer perpendicular drives in 2006 - I will not be impressed.

Here is some real breakthroughs that have been tested and proven to work....2.5TB by 2009
