Break Through Performance Barriers
Now, with a Seagate Desktop Solid State Hybrid Drive (SSHD), you can experience the performance of a solid state drive for a fraction of the cost. Desktop SSHD fuses solid state storage with a traditional hard drive to deliver the best of both worlds: blazing-fast performance and high capacities at prices that work.

Solid State Speed, Hard Drive Budget
Seagate Desktop SSHD leverages several gigabytes of NAND flash to deliver the performance benefits of solid state drives. SSHD is 4X faster than standard 7200RPM hard drives*; it improves system-level performance by an average of 20%; and you'll get far faster bootups.

*As measured by PC Mark Vantage benchmark software

Capacity without Compromise
Solid state drives are typically only affordable in very low capacities, but there's no need to compromise with a Seagate Desktop SSHD. Choose from 1TB, 2TB or 4TB models at prices that make sense.

Installs with Ease
Seagate Desktop SSHD installs and communicates with your desktop computer exactly like a standard hard drive. It's fully compatible with standard SATA technology, and there's no need to worry about what OS you're using: desktop SSHD is OS-, driver- and software-independent.

Windows® 8 Boot-Ups in Less Than Ten Seconds
Seagate Desktop SSHD delivers the "instant-on" experience you crave, cutting boot times by 40% - 60% compared to standard hard drives. Plus, with Windows® 8 support, you'll experience a new standard in responsiveness: Startup-to-ready in less than ten seconds.

Performance that Adapts to You
Seagate Adaptive Memory™ technology is the secret to Desktop SSHD's stunning responsiveness. Adaptive Memory software learns what data you use most then copies it to the drive's solid state memory, where it can be accessed in an instant.

Rock-Solid Reliability
By blending solid state storage with a traditional hard drive, Desktop SSHD reduces the wear issues associated with both technologies. Mechanical wear and tear to the hard drive is reduced since frequently-used data gets stored in the solid state memory. This also reduces wear on the solid state memory by minimizing the frequency of data erasures and rewrites. Your Seagate Desktop SSHD will help protect your precious data even as it delivers mind-blowing performance.
