Seagate Announces Backup Plus Hard Drives
Seagate's new Backup Plus line of external storage devices can back up local documents as well as Facebook photos.
Seagate has reinvented backing up your content with its new line of mobile 2.5-inch external hard drives. The Backup Plus drives feature Seagate Dashboard, an interface that will backup your content with one-click. Designed for both Mac and PC users, Backup Plus hard drives also provide a way to share and save photos to and from social networking sites. This means that no matter where your content is saved, the drive can retrieve it and back it up.
"Backing up needs to be an essential part of everyone's digital life. Nearly everything that is dear to us is now in a digital format; from tax documents, to emails, to family photos and video, many of these files can not be recreated in the event of an accidental loss or system failure," said Scott Horn, vice president of Marketing at Seagate.
"Seagate is in the business of keeping digital content and files protected in every aspect, whether it is in the cloud, stored on PC or with our external consumer products. Backup Plus is a product that eliminates the barriers to protecting these digital assets. The new Dashboard delivers a simple and complete backup experience with the added benefit of saving photos and video stored on Facebook and other social networks."
Powered by USB 3.0, the new portable 2.5-inch drives require no external power source and work interchangeably with Mac and PC.
Available starting today in red, blue, silver, and black, the portable 2.5-inch external drives will be offered in 500GB ($119.99), 750GB ($129.99), and 1TB ($139.99) capacities. The larger 3.5-inch desk drives will be offered in 1TB ($129.99), 2TB ($149.99), 3TB (179.99), and 4TB ($249.99) capacities.

its getting o so close to where i will buy a 4tb drive, i can almost taste it.
Is for the size of a backup drive... 2,5...3,5 or even 5.25 don't matter much. Speed and especially Reliability are important to me.
I have a suspicion that a larger drive would have a lower failure rate.
That's what I what I meant. a larger disk at the same RPM will still have more data passing under the read/write head (on the outer portion of the drive).
As for turbulence, I don't think that would be a problem; besides, they could always create a vacuum or at least low pressure environment inside the drive to take care of that.
