Hitachi aiming for 5TB hard drive by 2010

Hitachi has announced plans to have a commercial 3.5-inch hard drive on the market that can hold 5TB. They hope for this to be available by 2010.

Hard drive specialist Hitachi Global Storage Technologies is continuing to push HDDs to the limit, with a strong emphasis on increasing capacity and with a clear goal in mind.

The space will be achieved using 'current perpendicular-to-the-plane giant magnetoresistance', or in short, CPP-GMR.
CPP-GMR pushes data density above 1TB per square inch, a long-awaited threshold that promises drives many times larger than those available today.

With hard drives, the performance is directly related to the density and speed of the drive. The denser the platter inside the drive, the faster the drive will be. The most dense platters now are around 334GB, so 1TB drives are made up of 3 platters. Actually most use 4 platters and some even use 5! (which is bad for heat). So, if the limit for each platter is 1gb, that gives you 5gb with 5 platters. Now performance wise, there will only be so much data underneath the head on each rotation, and drives are already tweaked fairly well for performance, so performance won't leap that much above the very latest current technology (like supposedly the new 32mb cache twin processor WD drives coming out). The only way to increase performance above this is to increase the rotation speed, we may see slighly faster drives but the faster they spin the more power they use, which is a big issue these days. We probably wouldn't have seen 10,000rpm drives, but if efficiency wasn't such an issue we may have seen say 8400rpm drives by now

Excellent.
I plan for a new PC in 2010/11/12 so this'll be a nice addition :D
Not close to using my current 250GB so that'll be massive.

I've still got an old Circuit City sales paper advertising 1GB hard drives, 1GB!! I remember looking at it the morning it came and thinking how incredible that was and how I'd probably never need or be able to afford such a massive drive.

An ad? I actually bought a Micropolis 1GB drive for $999. I ran a BBS in the early 90s... :)

The drive was a 5.25" full height (two drive bays!) drive... I think I still have it somewhere. LOL.

I can't wait to make a nice raid array out of a few of these


lol 1TB is overkill


5TB SSC overkill edtion IMO


2X 5TB HDD Raid0 will be ****** insane speedwise/storage i guess i will be really tidy to have em in raid5

thats what I was thinking

5 x 5TB Raid5 = 20TB of redundant usable space. Thats a lot of data, Hell just one of these drives alone is more than my current raid5 array (5 x 1TB = 4TB unformatted redundant space)

1TB is way to small for the Media Server folk, We need lots of room for SD/HD, DVD Rips, BluRay Rip Video

They should make the hard drives more reliable and resistant to mechanical failures instead of focusing solely on storage capacity...... i'm tired of having to replace at least one of my hds every 1.5-2 years.

Speak for yourself. I've got 600 GB of NAS storage and I need more. As a matter of fact, I'm heading down to the store not to pick up a pair of 1TB drives.

So if you're NOT going to pick up a pair of 1 TB drives, what are you going to pick up?

Sorry, somehow I inserted a "not" in there. I do believe I need more coffee. :happy:

I was just messin with ya. :P

I think the increase in drive space is great but I can just hear the tech support calls from the noobs that don't backup. "Um, yeah like my computer doesn't say I have a hard drive and like I had all my music from like 5 decades on there and all these videos, it was a few Terabytes." We'll need some other good formats out to backup all this massive amounts of information.

Yes, it's getting more and more important to back up things. At this scale, I'd buy them in pairs, one as the backup. They're quickly getting so cheap anyway.

Gee, how about 1 TB SSD by.. NOW! heh

Do you got ton of cash for BiTMICRO Altima E3S320

I think they (and other HDD manufacturers) should start making more solid state (or hybrid drives for that matter) which hopefully will bring prices down.

HDD's are still good, but at this point, I feel we need speed over storage

Thank god..

Please introduce 10TB hard drives in 2012..

With Blue Ray disks of 25GB and in near future 50GB, how can somebody backup his movies.. :P

What?! first of all you don't need pure 50GB bluray, no one sane can notice or care about the difference between 50GB bluray and any high quality HD codec like H.264.

1TB hdd can store ... lots of such movies.

It's like CPU's, first was the speed in Ghz, now is the number of cores and cache memory..

Next will be hard drives when they feel they can't push more GB for disk, they will focus on speed..

And I may be very wrong but I think in 3.5-inch size, there won't be much TB they can put in a drive.. Off course they may raise the physical size or just progress in speed..

you are very wrong if you think a few TB's are the limit
