2010: the 5TB 3.5in HDD cometh

Hitachi has pledged to release a 5TB 3.5in hard drive within twoyears, and it claims two of the drives will boast enough capacity tostore everything in your brain.
According to a report by Nikkei Net, Hitachi Global StorageTechnologies will use Current-Perpendicular-to-Plane GiantMagnetoresistance (CPP-GMR) magnetc read heads to achieve the aim.This, the firm claims, will allow its drives to store 1TB of data inevery square inch of the recording surface.
Hitachi’s announcement is a step on from a claim it made back inOctober 2007 that 4TB of storage could become a reality by 2011.
It’s worth noting though that Hitachi’s not the first storagecompany to promise super-capacity HDDs. Back in August 2007, rival Fujitsu announcedthat 2.5in disks were its proposed ‘patterned medium’ for such compactstorage. It too plans to have commercial models available by 2010.

Fujitsu's approach uses anodised aluminium to create a pattern of"nanoholes", each holding a portion of magnetic material used to storea single bit of data. The aluminium-oxide surrounding these so-called'nanoholes' helps magnetically insulate each bit from all the others,preventing one from affecting another, which might lead to datacorruption.
Nonetheless, Dr Yoshihiro Shiroishi from Hitachi has claimed thattwo of its 5TB will together “provide the same storage capacity as thehuman brain”.
So, if your memory’s not great, then just buy a couple of 5TB drivesfrom Hitachi and download all your thoughts and memories onto them,before wiping the slate clean and staring afresh with another 10TB ofbrain capacity.

Good for Hitachi, maybe some day they'll do better than Seagate or WD. I've never used a hitachi drive before but if they accomplish this I hope they get at least in 3rd place of best disk maker. This will be such a convenience for file hosts.
