In the future, Seagate sees additional potential for on-disk encryption. The technology can be used to provide trusted applications with their own partitions that would otherwise be hidden from the operating system. That could allow, for example, an anti-virus program to keep its virus definition files separate from the system and free of potential corruption. It could also provide key storage for programs enforcing Digital Rights Management. Seagate is well aware that DRM isn't terribly popular among PC enthusiasts, but it's a reality for consumer electronics devices powered by the company's DB35 hard drive line.
Momentus 5400 FDE.2 drives will become available in the channel in December and as options in OEM systems by January. The drives will be more expensive than their non-FDE counterparts, but Seagate says the premium will be less than what you'd pay for software encryption.
