Hitachi working on 5TB hard disk drives

By on July 3, 2008, 2:01 PM
Solid state disks are slowly gaining ground on traditional hard drives, particularly in laptops, but that isnít stopping Hitachi from continuing to push HDDs to the limit. While recent developments in the field are already yielding one terabyte units, Hitachi believes they can have a commercial 3.5-inch hard drive on the market that can hold 5TB by 2010.

The company aims to achieve this boost in capacity with write heads that use something called current perpendicular-to-the-plane giant magnetoresistance (CPP-GMR), which pushed data density above one terabit per square inch. But it seems that Hitachi isn't the only one that is considering the release of a 5TB hard disk, Fujitsu also has some plans of their own Ė though fewer details on the technology used to achieve this have been made available.

OMG! I'm definitely going to need to plan the whole day to format that drive. And you can bet it will be in your best interest to install it in a RAID 1 (Mirror, or a 1+0 mirror/stripe) array for data protection. There's nothing affordable that I can think of to backup 5TB's other than a second 5TB drive.

3 years from now, people will be saying, "Remember when we used to have 500GB drives? We used to say 'How can we possibly use up all that hard-drive space?'". In our race to create ever larger drives and to store ever larger amounts of reality, it will be interesting to see how much of it will actually end up as dead storage. I've got 3 300GB+ hard-drives with stuff stored on them that I haven't looked at in over a year. I don't even know if I want to keep the data, but I'm afraid that if I delete it, I'll regret it later. I wonder whether this will create as many problems as it solves.Who's going to write the software that will dig through my old files, sort it and tell me whether it's still relevant?(I guess adobe bridge comes close...)

I think it's great that storage has come so far. Seems like a while ago where we were talking about utilizing crystals for unlimited storage, though. Wonder what happened to that. =XAnyway, I think this amount of storage is quite useful for students in animation/graphic design, as well as game development and the like. It's certainly not "really" intended for the typical home user. Though, I'm sure people could find a use for it. I have a 500gb external drive at home that's barely got anything on it.I suppose I'll be storing my old web designs/graphics on there, but it typically serves me little use besides MP3s. ;P
