Title: Seagate Unleashes New Terabyte Drives
Post by Pleonasm on Jun 26th, 2007 at 11:45am
Need more storage?

Seagate announced two models, the Barracuda ES.2 for enterprise  use and the Barracuda 7200.11 for consumer desktops. Both drives, set to ship in the third quarter, offer 7,200-rpm spin speeds, up to 32 MB of cache, average seek times of 8.5 milliseconds, and a reliability rating of 1.2 million hours mean time between failure (MTBF).

The Barracuda ES.2 has a serial attached SCSI (SAS) interface option along with SATA, and, according to Seagate, offers a 20 percent reduction in overall power consumption over earlier drives. Seagate noted the ES.2 boosts reliability with an industry-best unrecoverable error rate that is 10 times better than desktop-class drives.

$399 for a Terabyte

According to Seagate, the ES.2's applications for businesses include networked and tiered storage, disk-to-disk backup, archiving, and rich-media storage. The 7200.11, priced at $399.99, has a sustained data rate of 105 MB/sec, among the fastest for a desktop drive.

"We definitely have a race going on," said John Rydning, research manager for hard drives at IDC. Terabyte drives represent a "milestone in the evolution of hard disk drive technology," he added.

The new terabyte products have a couple of "subtle surprises," Rydning noted, such as the fact that Samsung is using three platters in its terabyte drives while Seagate is using four. "Samsung is pushing the areal density," he said, referring to how tightly data can be packed on a disk surface. "Historically, Seagate has been the leader."

An interesting aspect for businesses, he pointed out, is that the Seagate drive is being offered with a SAS interface as an option. "This is the first time that a high-capacity, 7,200-rpm drive has been offered with a native SAS," he said. Seagate said that SAS provides greater levels of reliability, data integrity, and performance.

Perpendicular Recording

Seagate's new terabyte drives use perpendicular recording, instead of longitudinal. Perpendicular recording enables magnetic charges to be stored vertically on a platter, providing a higher storage density.

Rydning said that, while perpendicular recording has been in commercial products for at least two years, it has primarily been used in mobile drives and is now moving into desktop and enterprise drives. He predicted that 60 percent to 65 percent of all hard disk drives will use perpendicular recording by 2008.

In a few years, industry observers might look at the terabyte milestone as we now look at the milestone of 1-GB drives. Reports are now indicating that Seagate's labs are working on drives that can store nearly 40 terabytes.

Barracuda 11.0

Seagate has always been my favorite drive. I know any drive can die at any time, but I feel more comfortable using my system when I know it runs on a Segate drive.

Plus I think they're quieter.

32 MB cache. Is that the most of any drive. Seems like were moving toward solid-state drives (memory-based) .. a little at a time.

Here's the product page:


Thx Pleo.

We should note that Hitachi (who bought IBM's disk storage dept) achieve 1-TB quite a while ago:

True, but Hitachi is notably more expensive at $440:


Seagate's drive brings HD storage prices to (what I consider) an amazingly low $.39/GB.  At this rate, it seems like tape drives and even optical storage will soon become impractical for even the largest data storage needs.  

Of course, optical storage may still have an advantage for the longevity of data.

I might be wrong, but I seem to recall reading that the Hitachi 1TB drive is only in limited production and is very difficult to obtain, whereas the Seagate unit is projected to be available “in volume” when it arrives.

No doubt, there will be a new set of hard disk drive benchmark comparisons on the way . . . .

As much as I like the price of this drive, a quick check of NewEgg shows you can get more storage for your money.  A Samsung Spinpoint of roughly comparable features offers 500GB for $109, or $.22/GB.  

Of course the newest and best is never the cheapest, and its nice to see that the price of the 1TB drive isn't unreasonable in comparison.

just to let you know, newegg has the hitachi 1TB drive in-stock:

The new {Seagate 1TB} drive does all of its storage on four platters instead of Hitachi's five platters.  This may sound like no big deal, but is actually a very significant change.  Less moving parts means less wear and tear on the drive, and thus a much better MTBF (mean time between failures).  All of this is backed by a massive 32MB cache on a 7200RPM spindle.

Of course, don't let that 7200 number fool you - this drive may be the fastest non-SCSI drive out there.  By managing to increase the density on the platters, Seagate has given the drive a bandwidth increase to a whopping 105MB/s.  In comparison, Western Digital's popular Raptor 10,000RPM drives have maximum sustained transfer rates of 84MB/s.  Could we be seeing the performance crown change hands, finally?

It appears that Seagate’s new 1TB hard disk drive will include encryption . . . .

SCOTTS VALLEY, Calif.-September 5, 2007-Responding to expanding demand for desktop and notebook PCs that deliver the highest levels of storage capacity with state-of-the-art security, Seagate Technology (NYSE:STX) today announced a 1 terabyte (TB) desktop hard drive that uses government-grade encryption to prevent desktop PC information from falling into the wrong hands, as well as a new 250GB 2.5-inch notebook hard drive.

“Data security has traditionally focused on preventing spoofing, sniffing, eavesdropping, denial-of-service and other threats to data traversing corporate networks and the Internet,” said Tom Major, Seagate vice president of Personal Compute Business. “Now that these networks have been hardened and are much more resistant to attack, computer thugs are increasingly targeting the place where data lives – on the hard drive. Seagate is answering this threat with the strongest security available for desktop PC information.”

The Barracuda FDE (full disc encryption) hard drive is the world’s first 3.5-inch desktop PC drive with native encryption to prevent unauthorized access to data on lost or stolen hard drives or systems. Using AES encryption, a government-grade security protocol and the strongest that is commercially available, The Barracuda FDE hard drive delivers endpoint security for powered-down systems. Logging back on requires a pre-boot user password that can be buttressed with other layers of authentication such as smart cards and biometrics.

Offered in capacities up to 1TB, this 7,200-rpm encrypting desktop PC hard drive also gives organizations an easy, cost-effective way to repurpose or retire desktop computers without compromising sensitive information and to conform to the growing number of data privacy laws calling for the protection of consumer information using government-grade encryption.

Today, business PCs are frequently repurposed when employees leave or new systems are issued, requiring IT managers to repeatedly wipe the hard drive clean of information to prevent the misappropriation of sensitive data. The process can take hours and is far from full-proof. With Seagate FDE drives, all hard drive information can be easily erased and the data rendered unreadable by simply deleting the encryption key for safe, fast repurposing or disposal.

Built with the same Seagate DriveTrust Technology that powers Momentus 5400 FDE.2 hard drives, the world’s first notebook disc drive with built-in encryption, Barracuda FDE provides the optimal balance of capacity, performance and security. DriveTrust delivers new levels of simplicity, transparency and cost-effectiveness for securing digital information. The Seagate security platform automatically protects data stored throughout the drive, not just selected partitions or files, and its security functions operate independently of the hard drive, preserving the hard drive’s full performance.
