Just upgraded my Macbook Pro to a Seagate Hybrid drive.

"Seagate Laptop SSHD leverages several gigabytes of NAND flash technology to deliver the performance benefits of solid state drives. SSHD is 4× faster than standard 7200 RPM hard drives*; they improve system-level performance by an average of 20%; and you'll get far faster bootups. Seagate Adaptive Memory technology is the secret to Laptop SSHD's stunning responsiveness. This 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."

It really works, I've had it for about 2 weeks now and it is booting up faster, launch programs faster. It sped everything up really. I highly recommend picking one up .

• 1 TB 5400 RPM 2.5" solid state hybrid drive 
• Utilizes Seagate flash management technology to deliver SSD-like performance 
• Integrates NAND flash with traditional hard drive storage 
• 9.5mm design for maximum capacity laptops 

Update: Still going strong. I didn't notice any changes in battery life. The only thing that I did notice is that its faster than my buddies BRAND NEW MacBookPro. Haha you should have seen the look on his face. My older early 2009 MBP out performing his 2012 MBP muahaha. Seriously go Buy it here!
