The hybrid drives combine two things from different worlds into one, the cheap storage, storage capacity, and reliability of mechanical hard drives and the speed of NAND-based SSDs. The drive will sort the most used files into the flash memory for speedy access while keeping the cold data on the mechanical part of the drive.
This method will provide you with better boot times than traditional hard disks and your most used apps will too. This is an ideal drive to upgrade older notebooks and give them a needed performance boost
