Six months after the first 750GB, Hitachi announces the 1TB marker

Not even hours after Seagate publically announced the company would unveil its 1TB hard drive sometime in the first half of 2007, Hitachi Global Storage has announced its 1TB drive.  Like Seagate, Hitachi GST claims the drive will be available in the second quarter of 2007.

The 1TB Hitachi Deskstar 7K1000 is just one of the drives in Hitachi's scope for next week's Consumer Electronics Show.  The company also announced its 750GB Deskstar 7K750, CinemaStar 7K750 and CinemaStar 7K1000.  Hitachi CinemaStar hard drives are specifically designed for digital video players and home-theater PCs.

Both Serial ATA and Parallel ATA versions of the new high-density monsters will make appearances.  The drives spin at 7,200 revolutions per minute with an average seek time of 8.7 milliseconds.  The SATA version of the Deskstar 7K1000 will feature a 32MB read head.

The 1TB Desktar utilizes five platters from Komag, while the 750GB Deskstar uses four.  Seagate, the first drive manufacturer to announce a 750GB drive last year, also uses Komag for its platter needs.

"The industry's first one-terabyte hard drive represents a milestone that is 50 years in the making, and it reasserts the hard drive's leadership as the highest-capacity, lowest-cost storage technology," said Shinjiro Iwata, chief marketing officer, Hitachi Global Storage Technologies. "In the 51st year, Hitachi is leading a new era for hard drives -- not only providing large amounts of affordable storage, but also customizing and optimizing hard drives to deliver products that are smarter, more durable and more useful to the consumer."

Seagate's Barracuda 7200.10 750GB drive launched with an MSRP of $499 in the middle of last year.  Hitachi has bold claims for the Deskstar 7K1000 -- the company claims it will launch with a price tag of $399, or just under $0.40 per gigabyte.

Perpendicular?

Will these utilize perpendicular storage?

I think they probably have to. The Seagate ones do, and I'd be very surprised if Hitachi was able to circumvent that and still get up to 1TB.

Either way, PMR offers other benefits too, and the Seagate 1TB announced other improvements like reduced heads (and I think even platters, though I may be wrong about that) that offer significantly better longevity and performance. If Hitachi can't match that, then Seagate remains on top despite the identical capacity.

Reduced heads? How is that possible? They still need one head per surface, don't they?

Yeah, I would assume so too. I might have misinterpreted the finer points but I'm basing that on this:

It's still the same... they just mean they have fewer heads and plates cause they use plates of higher density, it's like when Hitachi introduced it's 500GB disks with 5 plates (100GB) where the competition could do/did the same with just 4 plates (133GB for Seagate).

In theory less plates means cooler, quieter and more reliable HD, but theory is not always true when speaking of different HD manufacturers.

Hitachi does have this technology, so I would bet it does - I can't imagine why they wouldn't use it. However, the 1TB Seagate is reported to have only 4 platters relative to the 5 platters reported for the Hitachi. That is an interesting difference that would seem to give Seagate an advantage in terms of noise, heat, mass, reliability, etc.

seagate is on its second-generation PDR technology, hitachi is on its first-generation. the difference is seagate can use four platters (250GB each) and hitachi needs five platters (200GB each, the same as seagate's first-generation platter density)
