Terabye Laptop anyone
Segate has anounced they could have a Terabyte laptop harddrive in the near future.
This new technology could make possible 600GB 1.8 inch drive (Microdrive, cmeras), 1.46TB 2.5 inch drive (Laptop), 7.5TB 3.5 inch drive.
This is getting nuts.

July 05, 2006 (TechWorld.com) -- Seagate Technology Inc. plans to increase disk capacity by 10 times with new technology it has just patented, meaning a computer hard drive could soon be storing as much as a terabyte of data.
The Heat-Assisted Magnetic Recording (HAMR) technology created by Seagate includes nanotube-based lubrication to allow the read/write head of a disk to get closer to the surface and store more information.
The smaller the data-recording areas on a disk surface, the more of them that can be packed together, and subsequently the greater the capacity of the disk, Seagate said. But reading and writing ever-smaller bits means that the read/write head has to come closer to the disk surface, requiring a tough lubricant layer on the surface.
Storing data properly in extremely small areas requires the magnetic material to be heated during the writing phase, but this causes the lubricant film deposited on top of the magnetized recording layer to evaporate.
Seagate's patent resolves this problem by having a reservoir inside the disk casing that contains nanotube-based lubricant. Some of this is periodically pumped out as a vapor and deposited on the surface of the disk, replenishing the evaporated lubricant. The vapor deposition process is similar to that used in the production of CDs and DVDs.
Seagate anticipates that the new technology could increase disk capacity by a factor of 10, making possible a 600GB 1.8-in. drive, a 1.46TB 2.5-in. drive, and 7.5TB Barracuda 3.5-in. drive. The lubricant reservoirs will be built to last the life of the disk.
Seagate has not given a date by which the technology will appear in products.

geez i remember when i had a 386Mhz with a 250MB hard drive....now we are talking terabytes...before long we will have memory card readers implanted in our brain....just insert a bigger memory stick to store more knowledge....haha...

The thing you always have to remeber about these huge hard drives is what are you going to use to back them up? For now, the only practical answer is another like-sized hard drive. Not too shabby a deal for the drive manufacturers.

I've got an adaptec 2.5" enclosure holding a 100GB seagate notebook drive. I love it!

I just wish it was 300GB drive for holding all my personal data (images, music, etc).

the funniest part about the whole hard drive business is in its consumer market illegal downloading is keeping it alive. I mean seriously unless you are using hard drives for a server the liklihood of you filling a 300 gb drive up with legal media is unlikely.

He has at his fingertips his entire video collection without ever needing to change dvd's from his living room. And is always adding more to his collection.
I wish I had his setup.

I can see photographers with DSLR's filling that space up pretty quick.

I've been buying drives in twos for the last 3 or 4 years.

I know there are other big factors but illegal downloading I am sure is a good segment of the hard drive/codec business.

forgot about Tivos and people saving files from that...ok nevermind because that is what most of my hard drive is. I have a lot of seasons of shows but I dont have a tivo so i just download them.

The thing to remember about drive space and photography is that it's not about the size of the files coming out of the camera. If you put in any amount of time into processing an image you obviously want to keep the processed version. And if you're working in Photosop you probably also want to do most of your processing with layers so that you can go back and change things later. A processed file from an 8MP camera with five or six layers can easily swell to over 200 MB.
And as for video, well....
SD is about 228 MB per minute
HD is about 540/840 MB per minute (720/1080)

I have something like 600 movies at appox 7GB per movie(with extras) you are talking about 4TB right there, and with HD movies it will go even faster

Also, I won't care until they have it all as solid state. HDDs are so primative.

Although the number is very high, you can only write to solid state memory so many times before it begins to lose it's ability to retain the memory for long periods of time, or so I've heard from a few people.
And on top of that, the rate at which solid state memory is advancing is no where near the rate that hard disks are advancing. And the costs associated with manufacturing solid state memory is only now starting to decline.
At the end of '04 I paid $90 for a 1GB SD card, now they can be had for $40; Whereas hard drive prices have been dropping like mad!
Just last week I saw another ad at frys for a 500GB Serial ATA 300Mb/s drive for only $190!
As much as I'd love to have solid state memory for everything we're a long way from that.
I don't know what the differences are in access times between reading from solid state and hard disk space either.
